In the sixth section of his light quantum paper of 1905, Einstein presented the miraculous argument, as I shall call it. Pointing out an analogy with ideal gases and dilute solutions, he showed that the macroscopic, thermodynamic properties of high frequency heat radiation carry a distinctive signature of finitely many, spatially localized, independent components and so inferred that it consists of quanta. I describe how Einstein’s other statistical papers of 1905 had already developed and exploited the idea that the (...) ideal gas law is another macroscopic signature of finitely many, spatially localized, independent components and that these papers in turn drew on his first two, “worthless” papers of 1901 and 1902 on intermolecular forces. However, while the ideal gas law was a secure signature of independence, it was harder to use as an indicator that there are finitely many components and that they are spatially localized. Further, since his analysis of the ideal gas law depended on the assumption that the number of components was fixed, its use was precluded for heat radiation, whose component quanta vary in number in most processes. So Einstein needed and found another, more powerful signature of discreteness applicable to heat radiation and which indicated all these properties. It used one of the few processes, volume fluctuation, in which heat radiation does not alter the number of quanta. (shrink)

This paper defends the Quine-Putnam mathematical indispensability argument against two objections raised by Penelope Maddy. The objections concern scientific practices regarding the development of the atomic theory and the role of applied mathematics in the continuum and infinity. I present two alternative accounts by Stephen Brush and Alan Chalmers on the atomic theory. I argue that these two theories are consistent with Quine’s theory of scientific confirmation. I advance some novel versions of the indispensability argument. I (...) argue that these new versions accommodate Maddy’s history of the atomic theory. Counter-examples are provided regarding the role of the mathematical continuum and mathematical infinity in science. (shrink)

The bulk of Orientalist research regarding Islamic theological literature has neglected Ibāḍī theological opinions related to cosmology, which has led to an incomplete understanding of Islamic theology in the West and to a significant gap in Western scholarship. The omission of this important movement of Islam is understandable, considering the unavailability, lack of publication, circulation and translation of Ibāḍī texts. Therefore, this study seeks to address some of these gaps in the scholarship on early Islamic theology. The goals of this (...) article are: 1) to characterize the classical Ibāḍī theological literature dealing with the atomistic theory of substance and accident; 2) to review the texts of Ibāḍī scholars as they argued and engaged with other Islamic theological schools: pre-Bahshamiyya Muʿtazilites and Ashʿarites , in relation to the atomistic theory of substance and accident during the 3 rd /9 th century; 3) to survey the wide range of opinions among the early Ibāḍī theologians, and to examine the specific sources and themes that may have influenced this multifarious school of thought. Likewise, it is the aim of this article to demonstrate the common features in the Ibāḍī approach to producing theological literature during the formation of Islamic theology, and to explore how these early theologians may have gained access to cosmological themes that predate Islam. Résumé Le gros de la recherche orientaliste consacrée à la littérature théologique islamique a négligé les idées théologiques Ibāḍī à portée cosmologique, ce qui a conduit à une compréhension incomplète de la théologie islamique et à un manque considérable dans la recherche occidentale. L'omission de ce mouvement important de l'Islam est compréhensible étant donné que les textes Ibāḍī ne sont accessibles, publiés, diffusés et traduits que de façon très partielle. Cette étude vise donc à combler certaines de ces lacunes dans la recherche sur la première théologie islamique. Les objectifs de cet article sont de: 1) caractériser la littérature Ibāḍī classique portant sur la théorie atomiste de la substance et de l'accident; 2) examiner les textes d'auteurs Ibāḍī du iii e / ix e siècle dialoguant et discutant avec d'autres écoles théologiques islamiques, à savoir les Muʿtazilites pré-Bahshamiyya et les Ashʿarites , en lien avec la théorie atomiste de la substance et de l'accident; 3) passer en revue le grand nombre d'opinions soutenues parmi les premiers théologiens Ibāḍī, et examiner les sources et les thèmes spécifiques susceptibles d'avoir influencé cette école de pensée diversifiée. Cet article cherche aussi à identifier des traits communs dans l'approche Ibāḍī durant la période de formation de la théologie islamique, et à explorer les voies grâce auxquelles ces premiers théologiens ont pu avoir accès à des thèmes cosmologiques antérieurs à l'Islam.

Event concepts are unstructured atomic concepts that apply to event types. A paradigm example of such an event type would be that of diaper changing, and so a putative example of an atomic event concept would be DADDY'S-CHANGING-MY-DIAPER.1 I will defend two claims about such concepts. First, the conceptual claim that it is in principle possible to possess a concept such as DADDY'S-CHANGING-MY-DIAPER without possessing the concept DIAPER. Second, the empirical claim that we actually possess such concepts and (...) that they play an important role in our cognitive lives. The argument for the empirical claim has the form of an inference to the best explanation and is aimed at those who are already willing to attribute concepts and beliefs to infants and nonhuman animals. Many animals and prelinguistic infants seem capable of re-identifying event-types in the world, and they seem to store information about things happening at particular times and places. My account offers a plausible model of how such organisms are able to do this without attributing linguistically structured mental states to them. And although language allows adults to form linguistically structured mental representations of the world, there is no good reason to think that such structured representations necessarily replace the unstructured ones. There is also no good reason for a philosopher who is willing to explain the behavior of an organism by appealing to atomic concepts of individuals or kinds to not use a similar form of explanation when explaining the organism's capacity to recognize events. -/- We can form empirical concepts of individuals, kinds, properties, event-types, and states of affairs, among other things, and I assume that such concepts function like what François Recanati calls ‘mental files’ or what Ruth Millikan calls ‘substance concepts’ (Recanati 2012; Millikan 1999, 2000, 2017). To possess such a concept one must have a reliable capacity to re-identify the object in question, but this capacity of re-identification does not fix the reference of the concept. Such concepts allow us to collect and utilize useful information about things that we re-encounter in our environment. We can distinguish between a perception-action system and a perception-belief system, and I will argue that empirical concepts, including atomic event concepts, can play a role in both systems. The perception-action system involves the application of concepts in the service of (often skilled) action. We can think of the concept as a mental file containing motor-plans that can be activated once the individual recognizes that they are in a certain situation. In this way, recognizing something (whether an object or an event) as a token of a type, plays a role in guiding immediate action. The perception-belief system, in contrast, allows for the formation of beliefs that can play a role in deliberation and planning and in the formation of expectations. I distinguish between two particular types of belief which I call where-beliefs and when-beliefs, and I argue that we can model the formation of such perceptual beliefs in nonlinguistic animals and human infants in terms of the formation of a link between an empirical concept and a position on a cognitive map. According to the account offered, seemingly complex beliefs, such as a baby's belief that Daddy changed her diaper in the kitchen earlier, will not be linguistically structured. If we think that prelinguistic infants possess such concepts and are able to form such beliefs, it is likely that adults do too. The ability to form such beliefs does not require the capacity for public language, and we can model them in nonlinguistic terms; thus, we have no good reason to think of such beliefs as propositional attitudes. Of course, we can use sentences to refer to such beliefs, and thus it is possible to think of such beliefs as somehow relations to propositions. But it is not clear to me what is gained by this as we have a perfectly good way to think about the structure of such beliefs that does not involve any appeal to language. (shrink)

For any finite n 3 there are two atomic n-dimensional cylindric algebras with the same atom structure, with one representable, the other, not.Hence, the complex algebra of the atom structure of a representable atomic cylindric algebra is not always representable, so that the class RCAn of representable n-dimensional cylindric algebras is not closed under completions. Further, it follows by an argument of Venema that RCAn is not axiomatisable by Sahlqvist equations, and hence nor by equations where negation (...) can only occur in constant terms.Similar results hold for relation algebras.

Senior molecular geneticists were interviewed about their perceptions of the ethical and social implications of genetic knowledge. Inductive analysis of these interviews identified a number of strategies through which the scientists negotiated their moral responsibilities as they participated in generating knowledge that presents difficult ethical questions. These strategies included: further analysis and application of scientific method; clarification of multiple roles; negotiation with the public through public debate, institutional processes of funding, ethics committees and legislation; and personal responsibility.

In this stimulating investigation, Gideon Freudenthal has linked social history with the history of science by formulating an interesting proposal: that the supposed influence of social theory may be seen as actual through its co herence with the process of formation of physical concepts. The reinterpre tation of the development of science in the seventeenth century, now widely influential, receives at Freudenthal's hand its most persuasive statement, most significantly because of his attention to the theoretical form which is charac teristic. (...) of classical Newtonian mechanics. He pursues the sources of the parallels that may be noted between that mechanics and the dominant philosophical systems and social theories of the time; and in a fascinating development Freudenthal shows how a quite precise method - as he descriptively labels it, the 'analytic-synthetic method' - which underlay the Newtonian form of theoretical argument, was due to certain interpretive premisses concerning particle mechanics. If he is right, these depend upon a particular stage of con ceptual achievement in the theories of both society and nature; further, that the conceptual was generalized philosophically; but, strikingly, Freudenthal shows that this concept-formation itself was linked to the specific social relations of the times of Newton and Hobbes.

Critics who use historical evidence to challenge scientific realism have deployed a perfectly natural argumentative strategy that has created a profoundly misguided conception of what would be required to vindicate that challenge. I argue that the question fundamentally in dispute in such debates is neither whether particular terms in contemporary scientific theories will be treated as referential nor whether particular existential commitments will be held true by future scientific communities, but whether the future of science will exhibit the same broad (...) pattern of repeated, profound, and unpredictable changes in theoretical orthodoxy that such historicist critics argue characterizes its past.

The last‐half of seventeenth‐century England witnessed an increasing number of works published questioning the traditional notions of God's work of creation and providence. Ascribing agency to matter, motion, chance, and fortune, thinkers ranging from Hobbes, Spinoza, modern‐Epicureans, and other presented a challenge to the Anglican defenders of social and ecclesiastical order. By examining the genesis of the Boyle Lectures that began in 1692 with a bequest from Robert Boyle, we can see that while the Lecturers—three of whom will be examined (...) in detail (Richard Bentley, John Harris, and William Whiston)—assiduously defended classical notions of the God–world relationship, they did so without a great sense of panic or pessimism. This transitional period in the mode of conflict or concord between religion and science sheds interesting lights on matters such as argument from design, biogenesis without purposive, personal agents, and scriptural exegesis and scientific inquiries.

Contemporary arguments for forms of psycho-physical dualism standardly depart from phenomenal aspects of consciousness. Conceptual aspects of conscious experience, as opposed to phenomenal or visual/perceptual ones, are often taken to be within the scope of functionalist, reductionist, or physicalist theories. I argue that the particular conceptual structure of human consciousness makes this asymmetry unmotivated. The argument for a form of dualism defended here proceeds from the empirical premise that conceptual structure in a linguistic creature like us is a combinatorial (...) and compositional system that implicates a distinction between simple and complex, or 'atomic' and 'molecular' concepts. The argument is that conceptual atoms, qua atoms, are irreducible to anything else. If so, and if the atoms are essentially semantic, a form of dualism follows: though positively inviting naturalistic inquiry into the semantic and mental aspects of nature, it requires that we look at the mental as a primitive domain of nature. Schematically, then, the argument is as follows: Human consciousness/thought is conceptually structured. The human conceptual system is a 'particulate' system at a syntactic and semantic level of representation. This implies the existence of conceptual 'particles', concepts that have no further semantic decomposition. A conceptual atom cannot be explained in terms of anything that does not involve its own intrinsic properties. Physicalism as normally conceived is inconsistent with and. (shrink)

Strong arguments are presented by Hargrave suggesting that the crystallization of visual rhodopsin for high resolution analysis by X-ray crystallography or electron microscopy is feasible. However, the effort needed to achieve this goal will most likely exceed the resources of a single laboratory and a concerted approach to the research is necessary.

This article was first published as “Notation atomique et hypothèses atomistiques”, Revue des questions scientifiques, 31 (1892), 391– 457. It is the second of a series of articles Duhem was to publish in the Catholic journal Revue des questions scientifiques, in which he presents his understanding of what can justifiably be said about the structure of chemical substances as captured by chemical formulas. The argument unfolds following a broadly historical development of events throughout the course of the century which (...) was coming to a close as he wrote. He later reflected in his classic The Aim and Structure of Physical Theories – based in large part on articles which had appeared in the Revue – that “To give the history of a physical principle is at the same time to make a logical analysis of it” (p. 269). Logical analysis clearly dominates in the present article. The historical context was elaborated considerably in a later work, Le mixte et la combinaison chimique: Essai sur l’évolution d’une idée, which did not lead him to retract any aspect of his earlier position but provided a broader setting in which it could be elaborated. In particular, the Aristotelian influence, which is only hinted at here in some of the formulations (see especially the beginning of section VII) without mentioning Aristotle by name, is explicit in the later work, making Duhem’s own ontological conception a little clearer. A discussion of stereoisomerism, conspicuously absent in the present article, is also integrated into the later book. The same holds for Avogadro’s hypothesis. (shrink)

A matter of significance for the history of philosophy is the question of what are the issues that underlie Leibniz's response to Locke's Essay Concerning Human Understanding, in his own New Essays on Human Understanding. Exploration of that question can contribute to interpretations of both Locke and Leibniz. Equally important, it can provide insight into problems of philosophy that have their genesis in the seventeenth century. ;The dissertation uses the Essay and the New Essays to explore what it regards as (...) the central conflict between Locke and Leibniz: the conflict about the primacy of metaphysics. It takes for its focus their differing positions on atomism, contrasting the particle theory of matter that it finds central to the Essay with Leibniz's metaphysical unit, the monad. It develops the implications of those differing positions for an idea of nature specifically--nature here conceived as the arena in which science and metaphysics meet. ;The thesis of the dissertation is that the positions of Locke and Leibniz on atomism express opposing responses of philosophy to science; and, further, that this opposition had profound significance for the subsequent direction of philosophy. The first element in the thesis is the specific concern of the dissertation. Its second element, which suggests an approach to the history of philosophy since the seventeenth century, is an issue for further exploration. ;Locke's Essay is shown as a deliberate construction of an epistemology grounded in the new science, combining that purpose with an explicit rejection of the value of metaphysical speculation as the basis for knowledge. Locke's scientific background and orientation determine his analysis of ideas, of the powers and qualities of matter, and of real essences of material substances. ;In contrast, the New Essays is seen as asserting the primacy of metaphysics for the solution of epistemological and scientific questions. Leibniz's arguments against atomism are examined, to show why the basic reason for his rejection of all particle theories of matter is their violation of specific metaphysical principles. His positive position is presented in a discussion of the monad, emphasizing its characteristics in the realm of nature. (shrink)

The article addresses the old question of vitalism, starting with a very concrete and recent example: the successful laboratory production of the polio virus. Following this, the author recalls two types of arguments on the nature of living being: those of Leibniz and those of Claude Bernard. If, according to the biologists who produced the virus themselves, life’s unique trait is self-replication, what should one make of the dominant position in philosophy of biology today, which denies any argument based (...) on the substantial attribution of properties to living being? The essay concludes by suggesting a new way of acknowledging the specificity of life without turning it into a metaphysical property; a way which emphasizes the import of the philosophy of biology itself.

Stationary spacetimes containing a black hole have several properties akin to those of atoms. For instance, such spacetimes have only three classical degrees of freedom, or observables, which may be taken to be the mass, the angular momentum, and the electric charge of the hole. There are several arguments supporting a proposal originally made by Bekenstein that quantization of these classical degrees of freedom gives an equal spacing for the horizon area spectrum of black holes. We review some of these (...) arguments and introduce a specific Hamiltonian quantum theory of black holes. Our Hamiltonian quantum theory gives, among other things, a discrete spectrum for the classical observables, and it produces an area spectrum which is closely related to Bekenstein's proposal. We also present a foamlike model of horizons of spacetime. In our model spacetime horizon consists of microscopic Schwarzschild black holes. Applying our Hamiltonian approach to this model we find that the entropy of any horizon is one quarter of its area. (shrink)

During the 19th century atomism was a controversial issue in chemistry. It is an oversimplification to dismiss the critics' arguments as all falling under the general positivist view that what can't be seen can't be. The more interesting lines of argument either questioned whether any coherent notion of an atom had ever been formulated or questioned whether atoms were ever really given any explanatory role. At what point, and for what reasons, did atomistic hypotheses begin to explain anything in (...) chemistry? It is argued that 19th-century atomic accounts of constant proportions and isomerism had little to offer, whereas a non-atomic explanation of chemical combination was developed. Not until the turn of the century did atomism begin to do serious explanatory work in chemistry. (shrink)

This article highlights a use of analogies in science that so far has received relatively little systematic discussion: providing reasons for pursuing a model or theory. Using the development of the liquid drop model as a test case, I critically assess two extant pursuit worthiness accounts: that analogies justify pursuit by supporting plausibility arguments and that analogies can serve as a guide to potential theoretical unification. Neither of these fit the liquid drop model case. Instead, I develop an alternative account, (...) based on the idea that analogies facilitate the transfer of a well-understood modelling strategy to a new domain. 1Introduction2Case Study: The Development of the Liquid Drop Model3Plausibility Accounts 3.1Bartha on plausibility and analogical inference3.2Plausibility and the drop analogy4Analogies as a Guide to Unification5Generative Accounts 5.1Analogy-based modelling strategies5.2Did analogies play a merely generative role?6A New Pursuit Worthiness Account of Analogies 6.1Transferring understanding-with through analogies6.2Understanding-with and the liquid drop model7Conclusion.

ABSTRACTIn ‘Universals’, Ramsey declares that we do not, and cannot, know the forms of atomic propositions. A year later, in a symposium with Braithwaite and Joseph, he announces a change of mind: atomic propositions may, after all, be discoverable by analysis. It is clear from the 1926 paper that Ramsey intends this to be a revision of the 1925 claim. Puzzlingly, however, Ramsey does not mention analysis in 1925. My task in this article is to provide a justification (...) for that change of mind. My argument consists of two parts. I first show what relation holds between the negative 1925 assertion and the more positive 1926 assertion which allows us to read the latter claim as a retraction of the former, as Ramsey appears to have intended it. Then I shall argue that the retraction of the 1925 claim is forced upon Ramsey by reflection on the fact that three theses, all of which he held in or around the relevant period, are, rather surprisingly, revealed to be inconsistent.

Many have claimed that split-brain patients are actually two persons. I maintain that both the traditional separation argument and the more recent sophistication argument for the two persons interpretation are inadequate on conceptual grounds. An autonomy argument is inadequate on empirical grounds. Overall, theoretical and practical consequences weigh heavily in favor of adopting a one person interpretation.

This note presents an argument to show that trope theory, as usually conceived, gets into difficulties in handling certain ways in which two objects can resemble one another. Ways out of the difficulties are discussed briefly.

A study of the history of the atomic theory of matter between the time of Democritus and that of Newton. The classical atomic theory, we are told, consisted of four central doctrines: a firm commitment to indivisible units of matter; a belief in the reality of the vacuum; a reductionist conception of forms and qualities and a mechanistic account of natural agency. The work provides a critical account of the arguments used for and against these four theses during (...) three time-periods: Antiquity, the Middle Ages and the 17th century. Atomism was a minority position in Antiquity, rejected by most natural philosophers on the strength of Aristotelian objections. But Aristotle's own disciples gradually took his system apart in the Middle Ages, thus developing - albeit in a piecemeal manner - positions strikingly akin in some respects to classical atomism. So when Gassendi and others sought to revive atomism in the 17th century, the way was already prepared for them. This study is the first to emphasise the continuity of this process and the debt owed by the 17th-century moderns to the medieval critique of Aristotle. (shrink)

The scientific conception of change and motion raises two fundamental questions: Is there any evidence that the temporal order of events cannot legitimately be postulated to be continuous in Cantor's sense? Is it possible to account for such distinguishing properties of time as its possession of an "arrow" on the basis of assuming that events constitute a continuous type of order in Cantor's sense, and providing a coordinating definition for the ordering relation "later than"? We must raise these questions, since (...) at least four philosophers of the present century have denied the compatibility of the temporal structure of actual events with the order defined by Cantor's linear continuum and have held that a description of physical change which is based on the latter type of order is incompetent to account for the "arrow" of time and for such features of actual events as the latter involves. The philosophers in question are Henri Bergson, William James, Alfred North Whitehead and Paul Weiss. Each of these thinkers makes reference to Zeno's paradoxes of motion in setting forth his arguments. (shrink)

Among the French Cartesians of the second half of the seventeenth century, Géraud de Cordemoy stands out as the most radical. He was one of the first to argue that Cartesian metaphysics imply occasionalism, and he was alone in arguing that those same metaphysical commitments lead to atomism. This paper addresses the second of these positions. Following a discussion of what is taken to be the strongest version of his argument for atomism, consideration will turn to an objection against (...) Cordemoy, one that was raised in his own day by Gottfried Leibniz and more recently by Steven Nadler. The paper concludes with a response offered on Cordemoy's behalf. (shrink)

Elsasser outlines in an informal but meticulous fashion an organismic biology which promises, in his opinion, to combine the best features of epigenetic vitalism and preformationist mechanism. Mechanistic reductionism is for Elsasser an unverifiable metaphysical hypothesis; i.e., if the postulate of infinite homogenous classes is dropped from the axiomatics of Van Neumann's proof that the state of any system is, in principle, Quantum Mechanically determinable, it becomes combinatorically obvious that biological systems and classes are radically inhomogenous [[sic]], a fact which (...) operationally bars the way to any complete reductionism. The door is thus opened to an open-ended theoretical biology in which all questions do not have a truth-functional equivalent answer according to the axioms and laws of the science, and prediction in the science becomes statistical in a nonabsolute way. Elsasser is a physicist with more than a casual acquaintance with biology and his argument benefits by his obvious expertise in both of these areas. Philosophically, however, he is a lightweight and relies, in particular, too much on the ontological ice that might be cut by operationalism. Theories are not verified in the stringent operational sense; they are confirmed in a way which is not logically tied to the requirement that all laws be inductively established. Elsasser, however, has so much to say on the problem of reductionism in biology that is of obvious value that the book is easily recommended over these caveats.—E. A. R. (shrink)

Vasubandhu’s Twenty Stanzas (Viṃśikā) is among the most influential anti-Realist philosophical treatises in the history of Indian Buddhism. In particular, his refutation of the theories about the accumulation of atoms (paramāṇu) in stanza 12 if often regarded as compelling or even conclusive. But if this is the case, then the transition from stanza 12 to 13 would seem very odd, because in stanza 13 Vasubandhu bothers himself with yet another version of atomic accumulation. In this paper, I give an (...) interpretation of stanzas 12–13 by drawing clues from the Abhidharmakośabhāṣya and Dharmapāla’s Dasheng guangbailun shilun (Taishō 1571). I argue that Vasubandhu’s refutation in stanza 12 is valid only if we assume that the only possible way atoms can accumulate is by means of physical contacts with neighboring atoms. Conversely, if the opponents do not accept this assumption, then Vasubandhu’s refutation would miss its target. Given that stanza 13 cites the theory of the Kāśmīravaibhāṣikas and seeks to refute it, we must interpret that the Kāśmīravaibhāṣikas hold that atoms can form an accumulation in which atoms do not come into physical contact with each other, because this would be the only way to deal with the challenge previously posed in stanza 12. Dharmapāla provides more details about this theory and seeks to refute it again. Assuming the same Vasubandhu to be the author of Abhidharmakośabhāṣya, in which the author deals with the same issue, we must judge that Vasubandhu himself is quite aware of the limitations of his refutation in stanza 12, and this explains why he feels the need to devote stanza 13 to further refuting the theory of the Kāśmīravaibhāṣikas. However, I also argue that Vasubandhu’s refutation of this theory fails. If my argument holds, then we must conclude that the refutation of the accumulation of atoms in the Twenty Stanzas may not be successful. This explains, at least in part, why Dignāga feels the need to find new arguments in his Ālambanaparīkṣā. (shrink)

Jean Perrin’s proof in the early-twentieth century of the reality of atoms and molecules is often taken as an exemplary form of robustness reasoning, where an empirical result receives validation if it is generated using multiple experimental approaches. In this article, I describe in detail Perrin’s style of reasoning, and locate both qualitative and quantitative forms of argumentation. Particularly, I argue that his quantitative style of reasoning has mistakenly been viewed as a form of robustness reasoning, whereas I believe it (...) is something different, what I call ‘calibration’. From this perspective, I re-evaluate recent interpretations of Perrin provided by Stathis Psillos, Peter Achinstein, Alan Chalmers, and Bas van Fraassen, all of whom read Perrin as a robustness reasoner, though not necessarily in the same sort of way. I then argue that by viewing Perrin as a ‘calibration’ reasoner we gain a better understanding of why he believes himself to have established the reality of atoms and molecules. To conclude, I provide an alternative and more productive understanding of the basis of the dispute between realists and anti-realists. _1_ Introduction _2_ Perrin’s Reasoning: The Qualitative Argument _3_ Perrin’s Reasoning: The Quantitative Argument _4_ Perrin’s Realism _5_ Psillos, Achinstein, Chalmers, and van Fraassen on Understanding Perrin _6_ Conclusion.

A strong argument culture is characterized by at least five productive tensions, between: commitment and contingency, partisanship and restraint, personal conviction and sensitivity to the audience, reasonableness and subjectivity, and decision and non-closure. Differences in how communities manage these tensions explain why there are multiple argument cultures and, hence, why we need to understand arguing both within and among different cultures. The paper elaborates these five productive tensions, offers some examples of argument cultures that negotiate them in (...) various ways, and considers what it means to argue across cultures in a world that is both increasingly diverse and increasingly atomized.

The dissertation addresses the mind-body problem, and in particular, the problem of how to fit phenomenal consciousness into the rest of reality. Phenomenal consciousness - the what it’s like feature of experience - can appear to the scientifically inclined philosopher to be deeply mysterious. It is difficult to understand how the swirl of atoms in the void, the oscillation of field values, the firing of synapses, or anything physical can add up to the smells, tastes, feelings, moods, and so forth (...) that comprise our phenomenal experience. There is a series of arguments - the so-called “Conceivability Arguments” - that spells out this puzzlement. If this arguments are successful then there is no place for phenomenal consciousness in a completely physical reality. The main conclusion of this dissertation is that the Conceivability Arguments are all dependent on a flawed premiss, and that therefore these arguments - perhaps the most powerful among anti-physicalist arguments - all fail. Conceivability Arguments begin with the premiss that we can conceive of any physical or functional facts obtaining without there being any phenomenal experience at all. This is sometimes expressed by saying that zombies (i.e., beings that are our physical and functional duplicates, but possess no phenomenal experiences) are conceivable. The claim that zombies are conceivable does not have to do with our powers of imagination, or our psychological abilities, but rather with the nature of physical and phenomenal concepts. The reason that zombies are claimed to be conceivable is that each person’s thinking about phenomenal properties is completely dependent on her first person acquaintance with her own experience. From this assertion of conceivability it is inferred that zombies are genuinely possible. And this conclusion is incompatible with physicalism as that doctrine is usually understood. I argue that these arguments all fail; they are refuted by a master argument that I call “the Zombie Refutation.” The reason they fail has to do with the very nature of phenomenal concepts that gives rise to the conceivability of zombies. Because of the special nature of these concepts, the principle underlying the Conceivability Arguments - that principle that links conceivability and possibility - turns out to be self-refuting. Thus, the zombies that the Conceivability Arguments supposedly demonstrate to be possible, return to undermine those very arguments; a fitting revenge. (shrink)

Vasubandhu’s arguments against atomism in Viṃśikā stanzas 12–13 are not strong enough to disprove that atoms are simple partless substances. However, if we take the special composition question into consideration, Viṃśikā stanza 13ab can be regarded as an objection to so-called series-style answers, which results in an undesirable conclusion for the opponents, i.e. the Vaibhāṣikas. A step back to a simple bonding answer is not a good choice for the Vaibhāṣikas in responding to this objection because the simple bonding answer (...) leads to other difficulties and because some notions in Vaibhāṣika atomic theory entail multigrade relations in the material aggregates of atoms. Hence, the objection to series-style answers still makes sense in the refutation of Buddhist atomism through the claim that atoms are not proper parts of a material aggregate. (shrink)

The traditional Dung networks depict arguments as atomic and study the relationships of attack between them. This can be generalised in two ways. One is to consider various forms of attack, support, feedback, etc. Another is to add content to nodes and put there not just atomic arguments but more structure, e.g. proofs in some logic or simply just formulas from a richer language. This paper offers to use temporal and modal language formulas to represent arguments in the (...) nodes of a network. The suitable semantics for such networks is Kripke semantics. We also introduce a new key concept of usability of an argument. This is the beginning of a continuing research for adding contents to the nodes of an argumentation network. This research will allow us to address notions like ?what does it exactly mean for a node to attack another? or ?what does it mean for a network to be consistent? or ?can we give proper proof rules to manipulate networks?, and more.

The knowledge argument is an argument against physicalism that was first formulated by Frank Jackson in 1982. While Jackson no longer endorses it, it is still regarded as one of the most important arguments in the philosophy of mind. Physicalism is the metaphysical thesis that, roughly speaking, everything in this world—including tables, galaxies, cheese cakes, cars, atoms, and even our sensations— are ultimately physical. The knowledge argument attempts to undermine this thesis by appealing to the following simple (...) imaginary scenario: Mary is confined to a black-and-white room, is educated through black-and-white books and through lectures relayed on black-and white television. In this way she learns everything there is to know about the physical nature of the world. She knows all the physical facts about us and our environment, in a wide sense of ‘physical’ which includes everything in completed physics, chemistry, and neurophysiology, and all there is to know about the causal and relational facts consequent upon all this, including of course functional roles. (Jackson 1986, p. 291) The knowledge argument says that if physicalism is true, Mary knows everything in this world. However, it seems obvious that her knowledge is not yet complete. Suppose that..

This book examines the way in which Robert Boyle seeks to accommodate his complex chemical philosophy within the framework of a mechanistic theory of matter. More specifically, the book proposes that Boyle regards chemical qualities as properties that emerged from the mechanistic structure of chymical atoms. Within Boyle’s chemical ontology, chymical atoms are structured concretions of particles that Boyle regards as chemically elementary entities, that is, as chemical wholes that resist experimental analysis. Although this interpretation of Boyle’s chemical philosophy has (...) already been suggested by other Boyle scholars, the present book provides a sustained philosophical argument to demonstrate that, for Boyle, chemical properties are dispositional, relational, emergent, and supervenient properties. This argument is strengthened by a detailed mereological analysis of Boylean chymical atoms that establishes the kind of theory of wholes and parts that is most consistent with an emergentist conception of chemical properties. The emergentist position that is being attributed to Boyle supports his view that chemical reactions resist direct explanation in terms of the mechanistic properties of fundamental particles, as well as his position regarding the scientific autonomy of chymistry from mechanics and physics.

In this lucid and insightful study, Stephen Makin investigates a form of argument widespread in ancient Greek philosophy, where the absence of a reason for one alternative to be the case rather than another is used to establish substantive conclusions—where the alternatives are “indifferent”. Examples abound: Anaximander engages in such reasoning to show that the Earth does not move; Zeno of Elea to show that what is cannot be divided; Democritus to argue for finite divisibility, on the one hand, (...) and the infinite variety of atoms and worlds, on the other; not to mention the extensive use of such arguments in ancient skepticism.

Given that Lucretius offers a systematic and cohesive explanation of the workings of nature, we should not expect inconsistencies in his poem. The explanation presented by Lucretius emphatically rejects any interventionist divine machinery of the cosmos, offering in its place the eminently regular dynamics of atomic configuration and dissolution, which can explain everything that pertains to natural philosophy without necessitating the activity of any divinity. The reader who understands the basics of Lucretius’ philosophy, therefore, should be surprised that theDRNbegins (...) with an anthropomorphic description of the goddess Venus, whom the poet petitions to intervene actively in human affairs. Lucretius gradually refines this initial presentation of the goddess’ essence throughout the poem, suggesting that the Venus who inaugurates the poem must be nuanced once one has learned the basic principles of Epicurean philosophy. At the end ofDRN4, Venus is presented not as a divine being but as nothing more than the sexual drive shared by all creatures in nature (haec Venus est nobis, 4.1058). Historically scholars have been keen to ‘correct’ perceived inconsistencies such as this, either by arguing that such imperfections derive from later interpolators or by appealing to the incomplete nature of the text as we possess it. Of course, no one has suggested that Lucretius would have changed or removed the proem, so the Venus problem remains an issue. One major aim of this article is to show that the process we witness with Lucretius’ Venus is not inconsistent but programmatic, a point grasped by many with regard to Venus herself but not in respect to theDRNas a whole. In other words, this article extends this insight about Lucretius’ Venus, whose providential attributes are only provisionally attached to her at the outset of the poem and, in due course, are completely removed. In fact, I will argue that the technique of gradually redefining initial propositions—a process I will refer to as provisional argumentation—fundamentally informs Lucretius’ famous metaphor of the honeyed cup, and I will suggest that we ought to recognize this technique as a major aspect of Lucretius’ discursive method throughout theDRN.

It is commonly thought that Jean Perrin argued for the reality of atoms in the early twentieth century by using what Wesley Salmon calls a “common cause” argument, also known as robustness reasoning. After citing some concerns with this interpretation of Perrin, I offer a different interpretation of Perrin’s work that more closely depicts the details of Perrin’s reasoning in his relevant published writings. I then offer a historical argument that supports this interpretation and discuss the philosophical merits (...) of Perrin’s style of reasoning as I have presented it. I close by showing how my interpretation is distinct from previous interpretations of Perrin’s work. (shrink)

Argument“How should a modern artist react to the atomic age?” Time magazine posed this question in 1952 to open a review of an exhibition of paintings inspired by the “explosion of the atomic bomb” and by the “discovery of nuclear energy.” The energetic paintings of the Italian Spatial Movement were, according to Time, “almost as explosive as the bomb itself.” “Explosiveness” was a defining feature of much 1950s art, whose main impulse, gestural abstraction, has previously been understood (...) as the urgent expression of the artist's subjectivity. This paper argues that explosiveness in art can also be seen as an “expression” of the realities of the nuclear era. Postwar artists were ambivalent about the explosive forces, both liberating and devastating, that lay within the atom. Toward the end of the 1950s, no longer content merely to represent atomic disintegration, some artists went so far as to propose the outright self-destruction of the work of art as the only fitting means of expression in the atomic age.One must – and this is not an exaggeration – keep in mind that we are living in the atomic age, where everything material and physical could disappear from one day to another, to be replaced by nothing but the ultimate abstraction imaginable.– Yves Klein 1958.

Le présent article éclaire le contexte empirique et argumentatif du développement de la théorie corpusculaire de la matière au 17 e siècle. Dans le cadre d'une conception unitaire de la nature l'hypothèse atomique livra une description imagée des phénomènes en deça du perceptible à l'instar du monde visible. Cependant, tant sur le plan de la méthodologie empirique que sur celui de l'épistémologie, ces analogies n'étaient pas sans poser des problèmes. Différents arguments ont concouru à leur légitimation, mais aussi à leur (...) réfutation ultérieure: la métaphore antique de la literarum similitudo‚ qui considérait les atomes comme les lettres du livre de la nature caractérisées par leurs formes, le progrès de l'instrumentation optique nourrissant l'espoir que le microscope rendrait directement visibles les atomes eux-mêmes, et enfin un scepticisme croisssant à l'égard de la tentative de rendre tangible l'essence de l'être. De Sennert et Jungius à Gassendi, Boyle et Locke, l'atomisme ontologique cédera finalement le pas à une notion de corpuscule qui laissera en suspens la question de l'essence des atomes. (shrink)

Francis Bacon's position on the existence of void and its nature has been mostly studied with regard to his views on the atom. This approach is undoubtedly right, but it disregards further topics related to Bacon's account of void, namely the world system and the transmutation of bodies. Consequently, a more comprehensive study of Bacon's view on vacuum seems desirable where all the contexts are taken into account. To address this desideratum, the present paper examines Bacon's different views on vacuum (...) drawing attention to the various contexts of the discussion. It also gives an evaluation of the arguments put forward in support of his positions. The first section presents a reconstruction of Bacon's consecutive positions and the reasons for his changes of mind. The second section lists the experimental facts traditionally cited in debates about vacuum and Bacon's interpretation of these. The final section evaluates the role that these experimental facts played in Bacon's arguments. As a result, it is shown that Bacon fits entirely into the general pattern of the early seventeenth century. Empirical arguments by themselves had little value for solving the question of the void; it was also necessary to have a formerly established theory. (shrink)

In abstract argumentation, each argument is regarded as atomic. There is no internal structure to an argument. Also, there is no specification of what is an argument or an attack. They are assumed to be given. This abstract perspective provides many advantages for studying the nature of argumentation, but it does not cover all our needs for understanding argumentation or for building tools for supporting or undertaking argumentation. If we want a more detailed formalization of arguments (...) than is available with abstract argumentation, we can turn to structured argumentation, which is the topic of this special issue of Argument and Computation. In structured argumentation, we assume a formal language for representing knowledge and specifying how arguments and counterarguments can be constructed from that knowledge. An argument is then said to be structured in the sense that normally, the premises and claim of the argument are made explicit, and the relationship between the premises and claim is formally defined (for instance, using logical entailment). In this introduction, we provide a brief overview of the approaches covered in this special issue on structured argumentation. (shrink)

According to a common belief concerning the Mach-Boltzmann debate on atoms, the new experiments performed in microphysics at the turn of the 19th and 20th centuries confirmed Boltzmann’s atomic hypothesis and disproved Mach’s anti-atomic view. This paper intends to show that this belief is partially unjustified. Mach’s view on atoms consists in fact of different kinds of arguments. While the new experiments in microphysics refute indeed his scientific arguments against the atomic hypothesis, his epistemological arguments are unaffected. (...) In this regard, Mach’s epistemological approach remains relevant for today’s discussion on the status of the notion of atom. (shrink)

This paper solves the special composition question for solid objects and discusses the properties of wholes in relation to the properties of their parts, including emergent properties. By considering the causal properties of solid objects, this paper argues that it is possible for objects that are undoubtedly ontological units (called atoms) to combine to form a whole that is also an ontological unit of the same standing. It begins by considering the various different kinds of property that a whole object (...) could possess and the ways in which those properties could be related to the properties of its atoms, where some of the properties of the whole could be called emergent properties. There are properties of the whole that are determinate relative to the properties of the atoms, where the atoms’ possessing certain properties, being arranged spatially in a certain way, and with certain forces connecting them determine the instantiation of a specific property of the whole. There are also properties of the whole that are merely determinate as to kind, where the properties of the atoms merely determine that some property belonging to a certain kind will be instantiated. Further distinctions are made between properties of the whole that cannot be possessed by the atoms and properties of the whole that can. These distinctions are illustrated by a few physical examples. A number of different arguments are then given to show that a whole object composed of atoms possesses monadic properties of its own that are causally significant. Next a “real boundary condition for solid objects” is proposed, where the appropriate sort of boundary is both a spatial and an energetic boundary, one having to do with energy states. The paper concludes with a simple example of a solid object that is used to show that the description of the action and motion of the whole cannot be reduced to the descriptions of the actions and motions of its atoms.

In his 1918 logical atomism lectures, Russell argued that there are no molecular facts. But he posed a problem for anyone wanting to avoid molecular facts: we need truth-makers for generalizations of molecular formulas, but such truth-makers seem to be both unavoidable and to have an abominably molecular character. Call this the problem of generalized molecular formulas. I clarify the problem here by distinguishing two kinds of generalized molecular formula: incompletely generalized molecular formulas and completely generalized molecular formulas. I next (...) argue that, if empty worlds are logically possible, then the model-theoretic and truth-functional considerations that are usually given address the problem posed by the first kind of formula, but not the problem posed by the second kind. I then show that Russell’s commitments in 1918 provide an answer to the problem of completely generalized molecular formulas: some truth-makers will be non-atomic facts that have no constituents. This shows that the neo-logical atomist goal of defending the principle of atomicity—the principle that only atomic facts are truth-makers—is not realizable. (shrink)

J. H. van 't Hoff's 1874 Dutch pamphlet, in which he proposed the spatial arrangement of atoms in a molecule, is one of the most significant documents in the history of chemistry. This essay presents a new narrative of Van 't Hoff's early life and places the appearance of the pamphlet within the context of the 'second golden age' of Dutch science. We argue that the combination of the reformed educational system in The Netherlands, the emergence of graphical molecular modelling (...) within the theoretical and practical culture of chemistry during the 1860s and 1870s, as well as Van 't Hoff's own personal research trajectory, formed the background to his unprecedented attribution of spatial meaning to the traditional concept of atomic 'arrangement'. We also present a new English translation of the pamphlet, for we have found that the existing translation, published by G. M. Richardson in 1901, contains many errors, changes and omissions. The new version offers a more accurate rendition in English of Van 't Hoff's style and argument. (shrink)

In this paper I am analyzing Peter Unger’s famous argument in favour of mereological nihilism (according to this view elementary particles are the only existing objects), called: „Sorites of Decomposition”. This argument is based on the fact that we can remove one, single atom from a compound object without making it ceased to exist.

One of the most striking features of Giordano Bruno’s philosophy is the marriage of universal animation with atomism. This unusual combination produced an extraordinary image of the universe, which was governed by the World-Soul and its universal intellect along with an infinite number of living atoms or corpuscles, animated by their internal spiritual principle. After examining Bruno’s principal arguments on the World-Soul, universal animation and living atoms or corpuscles, this article explores two possible sources among the works of his near-contemporaries. (...) The first author, Agostino Steuco, tried to reconcile the doctrine of the World-Soul with Christianity, integrating the idea of Anaxagoras on the cosmic mind as the demiurgic agent of the universe. The second figure, Jacob Schegk, further elaborated his unusual atomistic or corpuscular reinterpretation of this Presocratic philosopher’s ideas. (shrink)

I introduce the implantation argument, a new argument for the existence of God. Spatiotemporal extensions believed to exist outside of the mind, composing an external physical reality, cannot be composed of either atomlessness, or of Democritean atoms, and therefore the inner experience of an external reality containing spatiotemporal extensions believed to exist outside of the mind does not represent the external reality, the mind is a mere cinematic-like mindscreen, implanted into the mind by a creator-God. It will be (...) shown that only a creator-God can be the implanting creator of the mindscreen simulation, and other simulation theories, such as Bostrom’s famous account, that do not involve a creator-God as the mindscreen simulation creator, involve a reification fallacy.
