Dr. Rice Holmes has thrown a flood of light on innumerable passages in Caesar's Commentaries, but in one small matter he has, as I hope to show, darkened counsel. In his recent work on the Roman Republic and the founder of the Empire his anxiety to retain the MSS. reading III. in Caesar , ‘Mittit … in Siciliam Curionem pro praetore cum legionibus III.,’ leads him to pervert or neglect the plain meaning of other passages in Caesar. He holds that (...) ‘Curio was not sent to Sicily with any legions,’ and that the ‘Domitian cohorts,’ which Caesar says he sent to Sicily straightway from Corfinium, are identical with the three legions which Caesar says he sent with Curio from Brundisium. Dr. Holmes believes that this was what Caesar really meant, though he expressed himself loosely. Let us see how it agrees with Caesar's other statements. (shrink)

Peter Winch's The Idea of a Social Science has been the subject of repeated misunderstanding. This discussion takes one recent example and shows how Winch's argument is gravely distorted. What is at issue is not, as is usually supposed, whether we can accept or endorse another society's explanations of its activities, but whether we have to look for an explanatory connection between concepts and action. Winch's argument is that before we can try to explain actions, we have to identify them (...) correctly. This can only be done by seeing how they, and the concepts they are associated with, fit within a way of life. Grasping its rule?following character is understanding action. Once the difficulties in making such identifications are appreciated, we will be less inclined to accept facile explanations why people in other societies do the things they do. (shrink)

Contemporary inscriptions prove practically beyond doubt that Philip V. was the son of Demetrius II. and of the Epeirot princess Phthia. But historians have always started from Eusebius' statement that he was the son of Chryseis, a Thessalian captive whom Demetrius married and who afterwards married Doson, and have tried to fit other things in with Eusebius. Now it does not much matter to us which of two unknown women was Philip's mother; but it does matter how we approach our (...) evidence, and we must start from the contemporary evidence and work downward, not vice versa. I need not here go through all the different theories based on the late evidence; what I am going to do is first to examine the inscriptions, which has not yet been done in this connexion, and then explain how Eusebius' blunder arose; for even if a definite statement be certainly wrong, we want to know how it got there.

This paper is a contribution to the question of how far Polybius fulfilled that part of an historian's duty which consists of acquiring information; it gives an instance, small in itself no doubt, where he definitely neglected to obtain good information which lay to his hand, and preferred to repeat a commonplace untruth of the literary hacks.

In the Transcendental Aesthetic (TA), Kant is typically held to make negative assertations about “things in themselves,” namely that they are not spatial or temporal. These negative assertions stand behind the “neglected alternative” problem for Kant’s transcendental idealism. According to this problem, Kant may be entitled to assert that spatio-temporality is a subjective element of our cognition, but he cannot rule out that it may also be a feature of the objective world. In this paper, I show in a new (...) way how Kant’s view (focusing on his conclusions about space) is not subject to this objection, by showing that he does not make the denial about mind-independent reality that he is typically held to make. The argument develops consequences of a new reading of Kant’s expression “an sich selbst” (‘in itself’; ‘in themselves’). I argue that “an sich selbst” or “per se” has a special, judgment-level role, so that this expression does not form new noun-terms adjectivally. It follows that the conceptual unit of Kant’s “Conclusions” in the TA is simply “things” (Dinge), since “things in themselves” is not a nominal expression; Kant adopts the Wolffian ontological use of “thing” as the basic kind-term for any existent. The arguments that things per se are not in space are arguments that space cannot be a necessary property or relations of things as a kind. I show that this does not involve the positive claim about mind-independent reality that inspires the neglected alternative objection. (shrink)

While the idea of philosophy as conceptual analysis has attracted many adherents and undergone a number of variations, in general it suffers from an authority problem with two dimensions. First, it is unclear why the analysis of a concept should have objective authority: why explicating what we mean should express how things are. Second, conceptual analysis seems to lack intersubjective authority: why philosophical analysis should apply to more than a parochial group of individuals. I argue that Hegel’s conception of social (...) ontology, focused on his concept of “ethical life” (Sittlichkeit), helps to explain how concepts (and their explication) have both objective and intersubjective authority in the social domain. Hegel claims that modern institutions are the product of self-conscious purposes, so that they are conceptually constituted. Concepts do not just represent these objects and so depend on a contingent relation to them. As many contemporary social ontologists agree, this means that our concepts of these institutions are uniquely epistemically “transparent.” They have objective authority. Concepts have intersubjective authority in the modern world as well, according to Hegel. However, I show that this feature of Hegel’s account does not rely on the solution to a philosophical problem. Rather, since the concepts of modern ethical life are “essentially contested,” their content depends on the practical and political agreement of modern subjects. This means that concepts can only have objective authority if some prior intersubjective agreement has been reached. The role of philosophy as conceptual analysis is thus importantly dependent on political developments. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Sovereignty of Reason: The Defense of Rationality in the Early English Enlightenment by Frederick C. BeiserJohn W. YoltonFrederick C. Beiser. The Sovereignty of Reason: The Defense of Rationality in the Early English Enlightenment. Princeton: Princeton University Press, 1996. Pp. xi + 332. Cloth, $39.50.Beiser characterizes the methodology of his study as historical and philosophical: historical in placing texts in their own context and in uncovering the intentions (...) of their authors; philosophical in reconstructing and appraising arguments (ix). Both methods are necessary for good historical work. The second is often practiced without the first, to the detriment of philosophy and its history. “A philosopher who reconstructs arguments without the aid of history indulges in mere guesswork and anachronism, measuring the standards of philosophical relevance and importance by the concerns of his own age” (x). Equally, understanding the arguments and ideas of, e.g., seventeenth-century writers, “also involves testing their truth: seeing how they cohere with one another, what their consequences are, whether they follow from the evidence adduced for them, and if they reply to the objections made against them” (x). This splendid study of the role of reason in seventeenth-century religion, science, and philosophy is a fine example of careful textual-historical scholarship with rigorous philosophical analysis.The goal of his study is to tell “the story of how rationalism, in the very specific sense of the sovereignty of reason, arose in seventeenth-century England” (5). Starting with an introduction which discusses such topics as “The Paradox of the English Enlightenment,” “Rationalism in the English Church,” “The Enlightenment and the New Sciences,” Beiser proceeds to detailed presentations and discussions of “The Protestant Challenge” (Chap. 1); Richard Hookers’s defense of reason (Chap. 2); the views of the Great Tew Circle, e.g., Falkland, Chillingworth, Hammond, Hales (Chap. 3); the Cambridge Platonists (Chap. 4); the nature of Enthusiasm (Chap. 5); John Toland and Deism (Chap. 6); and ethical rationalism (Chap. 7).Many of the topics covered have been the subjects of other books and articles. What marks Beiser’s account is the freshness of his approach, the many new insights and suggestions about the tensions between the holders of traditional doctrines and newer challenges. Beiser’s writing is clear, and the issues are carefully presented and analyzed. One of the central themes is the mistake of equating “rationalism with the critique or rejection of religion” (15), of identifying enlightenment with secularization (14). The appeals to reason often emerge from within orthodox religion, whose defenders were trying to cope with their own internal tensions. “Once we consider the Cambridge Platonists’ early reaction to predestination, it becomes clear that it was not Hobbes but Calvin who first posed the danger of atheism for them. For it was Calvin’s theology, and not Hobbes’s materialism, that inspired the fear of God that [End Page 138] they regarded as the source of atheism. In the eyes of the Cambridge Platonists, Hobbes’s materialism was only a false remedy for that fear...” (147). A similar point is made later: “the foundations of a rational theology” in Whichcote “did not arise from any need to combat a creeping Hobbesianism. Rather, it grew up from the inner struggles and torments of the Protestant soul” (165).Equally significant is Beiser’s analysis of enthusiasm, the appeals to divine inspiration rather than to reason or evidence: “We should be aware of accepting the contemporary caricature of the enthusiasts, which portrayed them as zealous and ignorant anti–intellectuals with no cogent or coherent philosophical position of their own” (187). His analysis of the enthusiasts stresses the epistemological nature of their position, rather than the usual theological, ethical, or political dimensions (193). He insists that “enthusiasm is essentially a philosophical concept. Historically, it arose as a response to the problem of the sources and criteria of religious knowledge” (187). The search for criteria is a pervasive feature of Beiser’s study: Luther’s and Calvin’s efforts to draw the boundary between faith and reason (24); Richard Hooker’s failure to “provide an epistemological foundation for his theory of natural law” (67); the need for a criterion to distinguish genuine from false revelation...

"More than any thing else technology creates our world. It creates our wealth, our economy, our very way of being," says W. Brian Arthur. Yet, until now the major questions of technology have gone unanswered. Where do new technologies come from -- how exactly does invention work? What constitutes innovation, and how is it achieved? Why are certain regions -- Cambridge, England, in the 1920s and Silicon Valley today -- hotbeds of innovation, while others languish? Does technology, like biological life, (...) evolve? How do new industries, and the economy itself, emerge from technologies? In this groundbreaking work, pioneering technology thinker and economist W. Brian Arthur sets forth a boldly original way of thinking about technology that gives answers to these questions. The Nature of Technology is an elegant and powerful theory of technology's origins and evolution. It achieves for the progress of technology what Thomas Kuhn's The Structure of Scientific Revolutions did for scientific progress. Arthur explains how transformative new technologies arise and how innovation really works. Conventional thinking ascribes the invention of technologies to "thinking outside the box," or vaguely to genius or creativity, but Arthur shows that such explanations are inadequate. Rather, technologies are put together from pieces -- themselves technologies -- that already exist. Technologies therefore share common ancestries and combine, morph, and combine again to create further technologies. Technology evolves much as a coral reef builds itself from activities of small organisms -- it creates itself from itself; all technologies are descended from earlier technologies. Drawing on a wealth of examples, from historical inventions to the high-tech wonders of today, and writing in wonder fully engaging and clear prose, Arthur takes us on a mind-opening journey that will change the way we think about technology and how it structures our lives.

This work aims to describe how developments in thinking on evolutionary biology require re-assessment of initial rejection of the relevance and applicability of neo-Darwinian evolution to the Gaia hypothesis.

Our only channel of information about the world is the impact of external forces on our sensory surfaces. So says science itself. There is no clairvoyance. How, then, can we have parlayed this meager sensory input into a full-blown scientific theory of the world? This is itself a scientific question. The pursuit of it, with free use of scientific theory, is what I call naturalized epistemology. The Roots of Reference falls within that domain. Its more specific concern, within that domain, (...) is reference to concrete and abstract objects: what such reference consists in, and how we achieve it. (shrink)

They then examine developments in the present century.

Our understanding of what microbes are and how they evolve has undergone many radical shifts since the late nineteenth century, when many still believed that bacteria could be spontaneously generated and most thought microbial “species” (if any) to be unstable and interchangeable in form and function (pleomorphic). By the late twentieth century, an ontology based on single cells and definable species with predictable properties, evolving like species of animals or plants, was widely accepted. Now, however, genomic and metagenomic data show (...) that lateral gene transfer compromises this picture of stability and predictability, and refocuses our attention on multilineage communities. Treating such communities as unstable but identifiable evolving “individuals” makes us again pleomorphists, of a sort. (shrink)

As automating technologies are increasingly integrated into workplaces, one concern is that many of the human workers who remain will be relegated to more dull and less positively impactful work. This paper considers two rival theories of meaningful work that might be used to evaluate particular implementations of automation. The first is achievementism, which says that work that culminates in achievements to workers’ credit is especially meaningful; the other is the practice view, which says that work that takes the form (...) of an open-ended practice is especially meaningful. Of the two, the practice view is the better tool for assessing the future of meaningful work, because achievementism is explanatorily inadequate in two ways. Moreover, the practice view can explain why the most meaningful forms of work cannot be automated. A procedure can only be automated as long as the steps are defined, whereas, in such work, which steps to take is indefinitely open to redefinition. This reveals the real threat to meaningful work to be a political-economic one. The relevant ethical questions there have to do with how much creative control workers retain in crafting their own jobs, when those jobs involve meaningful work in collaboration with machines; and how to liberate workers from jobs that do not involve meaningful work, which should be left to machines anyway.

The origin and prevalence of transposable elements may best be understood as resulting from “selfish” evolutionary processes at the within-genome level, with relevant populations being all members of the same TE family or all potentially mobile DNAs in a species. But the maintenance of families of TEs as evolutionary drivers, if taken as a consequence of selection, might be better understood as a consequence of selection at the level of species or higher, with the relevant populations being species or ecosystems (...) varying in their possession of TEs. In 2015, Brunet and Doolittle made the case for legitimizing claims for an evolutionary role for TEs by recasting such claims as being about species selection. Here I further develop this “how possibly” argument. I note that with a forgivingly broad construal of evolution by natural selection we might come to appreciate many aspects of Life on earth as its products, and TEs as—possibly—contributors to the success of Life by selection at several levels of a biological hierarchy. Thinking broadly makes this proposition a testable Darwinian one. (shrink)

Recent perspectives on corporate social responsibility have called for increased research on how CSR affects individuals. Research is needed to examine whether individual differences affect the relationship between CSR and individual reactions to CSR. In response, this experimental study examined how perceptions of corporate citizenship influence job applicant attraction and work role definitions. Personal values and education concerning CSR are considered as interactive factors affecting the influence of perceptions of corporate citizenship. Results indicate that perceived corporate citizenship had a greater (...) impact on job applicant attraction for those individuals who received prior education regarding CSR and for those who were higher in other-regarding value orientation. Furthermore, perceived corporate citizenship had a positive impact on the extent to which participants defined CSR as a personal work role responsibility. The authors also discuss the practical implications of these results for job applicant attraction and employee socialization. (shrink)

In this highly original work, Teed Rockwell rejects both dualism and the mind-brain identity theory. He proposes instead that mental phenomena emerge not merely from brain activity but from an interacting nexus of brain, body, and world. The mind can be seen not as an organ within the body, but as a "behavioral field" that fluctuates within this brain-body-world nexus. If we reject the dominant form of the mind-brain identity theory -- which Rockwell calls "Cartesian materialism" -- and accept this (...) new alternative, then many philosophical and scientific problems can be solved. Other philosophers have flirted with these ideas, including Dewey, Heidegger, Putnam, Millikan, and Dennett. But Rockwell goes further than these tentative speculations and offers a detailed alternative to the dominant philosophical view, applying pragmatist insights to contemporary scientific and philosophical problems. Rockwell shows that neuroscience no longer supports the mind-brain identity theory because the brain cannot be isolated from the rest of the nervous system; moreover, there is evidence that the mind is hormonal as well as neural. These data, and Rockwell's reanalysis of the concept of causality, show why the borders of mental embodiment cannot be neatly drawn at the skull, or even at the skin. Rockwell then demonstrates how his proposed view of the mind can resolve paradoxes engendered by the mind-brain identity theory in such fields as neuroscience, artificial intelligence, epistemology, and philosophy of language. Finally, he argues that understanding the mind as a "behavioral field" supports the new cognitive science paradigm of dynamic systems theory. (shrink)

This essay is concerned with six linguistic moves that we commonly make, each of which is considered in turn. These are: stating rules of representation; representing things categorically; mentioning expressions; saying truly or falsely how things are; saying vaguely how things are; and stating rules of rules of representation. A common-sense view is defended of what is involved in our doing each of these six things against a much more sceptical view emanating from the idea that linguistic behavior is fundamentally (...) messy. Both the fifth move and the sixth move involve vague concepts, and much of the essay is concerned with developing an approach to various problems and puzzles that attach to such concepts, most notably the sorites paradoxes.

Germany is considered to be a pioneer of social security systems; nonetheless, globalization and demographic changes have put enormous pressure on them. A solution is not yet in sight as the debate on the future of the German social security systems still lacks consensus. We argue that ideas matter and that the debate can benefit from a deeper reflection on the concept of social security. This objective is pursued along two lines. First, we take a historical perspective and reconstruct the (...) development of Germany's social security systems. Second, we scrutinize from a theoretical perspective how social security is conceptualized in public and theoretical debates. Behind the various positions, we identify four basic ideal types. We then analyze how these ideal types account for the benefits of social security systems and what role they assign to corporations in providing social security. While two ultimately reinforce potential conflicts between different groups in society, the other two ideal types reveal possible benefits for all. The last ideal type actually conceptualizes social security systems as insurance that fosters risky but overall productive investments in human and other forms of capital. Therefore, it can be shown that social security systems are not necessarily threatened by globalization and that incentives exist for corporations to invest in the provision of social security.

In this essay I suggest that we view design principles in systems biology as minimal models, for a design principle usually exhibits universal behaviors that are common to a whole range of heterogeneous (living and nonliving) systems with different underlying mechanisms. A well-known design principle in systems biology, integral feedback control, is discussed, showing that it satisfies all the conditions for a model to be a minimal model. This approach has significant philosophical implications: it not only accounts for how design (...) principles explain, but also helps clarify one dispute over design principles, e.g., whether design principles provide mechanistic explanations or a distinct kind of explanations called design explanations.

This volume, which is part of the Clarendon Aristotle Series, offers a clear and faithful new translation of Books II to IV of Aristotle's Nicomachean Ethics, accompanied by an analytical commentary focusing on philosophical issues. In Books II to IV, Aristotle gives his account of virtue of character in general and of the principal virtues individually, topics of central interest both to his ethical theory and to modern ethical theorists. Consequently major themes of the commentary are connections on the one (...) hand with other relevant Aristotelian texts and on the other with modern writings, both text-related and thematic. Since the main aim of the volume is to make Aristotle's thought as accessible as possible to readers who do not know Greek, considerable care is taken to elucidate both his technical vocabulary and significant features of his Greek idiom. C. C. W. Taylor also provides systematic comparisons with other translations into English and other languages, and frequent references to other commentaries, ancient, medieval, and modern. These features make the work useful to other scholars in the field as well as to students of philosophy, both undergraduate and graduate.In view of the widespread contemporary interest in the topic of virtue, the volume should appeal to students of ethics and to any reader who is concerned to see how fundamental questions of life and conduct were approached in a culture significantly different from our own.

W. V. Quine is one of the most eminent philosophers alive today. Now in his mid-eighties he has produced a sharp, sprightly book that encapsulates the whole of his philosophical enterprise, including his thinking on all the key components of his epistemological stance--especially the value of logic and mathematics. New readers of Quine may have to go slowly, fathoming for themselves the richness that past readers already know lies between these elegant lines. For the faithful there is much to ponder. (...) In this short book, based on lectures delivered in Spain in 1990, Quine begins by locating his work historically. He provides a lightning tour of the history of philosophy (particularly the history of epistemology), beginning with Plato and culminating in an appreciative sketch of Carnap's philosophical ambitions and achievements. This leads, in the second chapter, to an introduction to Quine's attempt to naturalize epistemology, which emphasizes his continuities with Carnap rather than the differences between them. The next chapters develop the naturalistic story of the development of science to take account of how our conceptual apparatus is enhanced so that we can view the world as containing re-identifiable objects. Having explained the role of observation sentences in providing a checkpoint for assessing scientific theories, and having despaired of constructing an empirical criterion to determine which sentences are meaningful, Quine in the remaining chapters takes up a variety of important issues about knowledge. He concludes with an extended treatment of his views about reference and meaning and his attitudes toward psychological and modal notions. The presentation is distinctive, and the many small refinements of detail and formulation will fascinate all who know Quine's philosophy. (shrink)

Subjectivism about meaning in life remains a viable option, despite its relative unpopularity. Two arguments against it in the literature, the first by Susan Wolf and the second by Aaron Smuts and Antti Kauppinen, fail. Pace Wolf, lives devoted to activities of no objective value need not be pointless, unproductive, and futile, and so not prima facie meaningless; and, pace Smuts and Kauppinen, subjectivism is compatible with people being mistaken about how meaningful their own lives are. This paper elaborates a (...) novel subjectivist view according to which becoming more fulfilled makes a life meaningful for a person. Becoming more fulfilled is a process that has being more fulfilled as its endpoint, and, as with any process, it can come to a halt before it is complete. More substantively, becoming more fulfilled by some x is a matter of aiming to do various activities well, where doing them well at least partly constitutes benefiting x, and requires that one be more fulfilled by x than one presently is. Finally, this paper shows why the becoming more fulfilled view is to be preferred to the standard subjectivist theory, the fulfillment view, and how it produces intuitive results. (shrink)

This study is an unusual contribution to the philosophy of mind in that it argues for the sometimes unfashionable view of dualism: that mind and matter are distinct and separate entities as Descartes believed. The author takes as his point of departure the imaginative hypothesis of disembodiment, which establishes the possibility of the mind's being a quite non-material thing. There are clear casual correlations between what is physical and what is mental, and the most serious issue confronting dualism since Descartes (...) has been how such an interaction is possible. Dr Hart sets out to answer this question by showing that the issue is as much about the nature of causation as it is about the natures of mind and matter. (shrink)

Organic chemists have been able to develop a robust, theoretical understanding of the phenomena they study; however, the primary theoretical devices employed in this field are not mathematical equations or laws, as is the case in most other physical sciences. Instead it is diagrams, and in particular structural formulas and potential energy diagrams, that carry the explanatory weight in the discipline. To understand how this is so, it is necessary to investigate both the nature of the diagrams employed in organic (...) chemistry and how these diagrams are used in the explanations of the discipline. I will begin this paper by characterizing some of the major ways that structural formulas used in organic chemistry. Next I will present a model of the explanations in organic chemistry and describe how both structural formulas and potential energy diagrams contribute to these explanations. This will be followed by several examples that support my abstract account of the role of diagrams in the explanations of organic chemistry. In particular, I will consider both the appeal to ‘hyperconjugation’ in the explanation of alkene stability and how the idea of ‘ring strain’ was developed to explain the relative stability of cyclic compounds.

In fact, nearly every scientist who has written on the general subject of evolution has felt compelled to show how deftly he can skate toward the abyss of teleology without falling in.J.H.

This goal has so far been pursued within a neoDarwinian theoretical framework which is relatively limited. Within this framework we can indeed understand remarkably well the mechanisms of replication and expression of (...) genes and the means by which replication and expression are regulated in cells; we know how genotype determines phenotype at the molecular level, in single cells. We are also close to an understanding of the relationship between genes and development in muticellular animals and plants. (shrink)

Some years ago, in the course of a general critique of what has sometimes been referred to as the covering law theory of explanation, I made the claim that perfectly satisfactory explanations can often be provided by indicating only one or a few necessary conditions, where we remain ignorant of the sufficient conditions, of what we nevertheless claim to understand. What seemed to me one identifiable type of such explanations I called “explaining how-possibly,” because it was a type more naturally (...) given in response to the question how it could be that a certain thing happened than to the more familiar question why it did so. In the present paper I propose to review certain objections to this thesis which have come to my attention in the interval, and to make such concessions as these seem to require. In fact, the concessions will be minor, since the general thesis still seems to me quite defensible. (shrink)

Gelfond and Lifschitz proposed the notion of a stable model of a logic program. We establish that the set of all stable models in a Herbrand universe of a recursive logic program is, up to recursive renaming, the set of all infinite paths of a recursive, countably branching tree, and conversely. As a consequence, the problem, given a recursive logic program, of determining whether it has at least one stable model, is Σ11-complete. Due to the equivalences established in the authors' (...) previous nonmonotone rule systems papers ), this applies equally to truth maintenance systems and default logics. (shrink)

It is commonly assumed that the expression “an sich selbst” (“in itself”) in Kant combines with terms to form complex nouns such as “thing in itself” and “end in itself.” I argue that the basic use of “an sich selbst” in Kant’s German is as a sentence adverb, which has the role of modifying subject-predicate combinations, rather than either subject or predicate on their own. Expressions of the form “S is P an sich selbst” mean roughly that S is P (...) ‘in its own right’ or without some further ‘condition’. Accordingly, “an sich selbst” should not be treated as forming complex nouns. This analysis has significant consequences for the interpretation of “thing in itself” in particular, for it implies that the latter is not a complete nominal expression. Instead, one must treat ‘an sich selbst’ as expressing how some S is a ‘thing’, looking to the wider sentential context. I conclude with a brief account of the new significance granted to the concept of a ‘thing’ (Ding) according to the present interpretation. (shrink)

Concreteness ratings are frequently used in a variety of disciplines to operationalize differences between concrete and abstract words and concepts. However, most ratings studies present items in isolation, thereby overlooking the potential polysemy of words. Consequently, ratings for polysemous words may be conflated, causing a threat to the validity of concreteness‐ratings studies. This is particularly relevant to metaphorical words, which typically describe something abstract in terms of something more concrete. To investigate whether perceived concreteness ratings differ for metaphorical versus non‐metaphorical (...) word meanings, we obtained concreteness ratings for 96 English nouns from 230 participants. Results show that nouns are perceived as less concrete when a metaphorical (versus non‐metaphorical) meaning is triggered. We thus recommend taking metaphoricity into account in future concreteness‐ratings studies to further improve the quality and reliability of such studies, as well as the consistency of the empirical studies that rely on these ratings.

This book is devoted to the problems of the growth of science. These prob lems, neglected for a long time by the philosophers of science, have become in the 60's and 70's a subject of vivid discussion. There are philosophers who stress only the dependence of science upon various sociological, psycho logical and other factors and deny any internal laws of the development of knowledge, like approaching the truth. The majority rejects such nihilism and searches for the laws of the (...) growth of science. However, they often overlook the role of the Correspondence Principle which connects the suc cessive scientific theories. On the other hand, some authors, while stressing the role of this principle, overlook logical difficulties connected with it, e. g. the problem of the incompatibility of successive theories, of the falsity of some of their assumptions, etc. I believe the Correspondence Principle to be a basic principle of the pro gress of contemporary physics and, probably, of every advanced science. How ever, this principle must be properly interpreted and the above-mentioned logical difficulties must be solved. Their solution requires, as it seems, revealing the idealizational nature of the basic laws of science, in any case of the quantitative laws of advanced sciences. This point has been recently emphasized by some Polish philosophers, especially in Poznan. (shrink)
