Empiricism is the doctrine that all knowledge has a strictly observational basis. Rationalism is the doctrine that least some knowledge has non-observational, purely conceptual basis. In the present work, empiricism is carefully considered and found to have four dire shortcomings: -/- (1) Empiricism cannot account for our knowledge of what doesn't exist, let alone what cannot exist. -/- (2) Empiricism cannot account for our knowledge of dependence-relations, given (1), coupled with the fact that 'P depends on (...) Q' is equivalent with 'not-Q either necessitates or is dispositive of not-P.' -/- (3) Empiricism cannot account for our knowledge of the past, the future, or the possible, given (2), coupled with the fact knowledge of any of these domains requires knowledge of conditional truths (truths of the form "if P, then Q") and therefore of dependence-relations. -/- (4) Empiricism cannot by itself apprise us of any truths, given (3), coupled with the fact that knowledge of conditional truths is necessary to recognize the truths implicit in any body of sensory data. -/- The arguments of key empiricists are closely examined. Special attention is paid to George Berkeley's arguments for idealism ('to be is to be perceive/conceived'). It is shown that, although Berkeley's arguments fail, profound insights are embedded in the very sophisms that vitiate those same arguments, the three most important ones being: -/- (i) That data-modelling and truth-identification at least sometimes coalesce, -/- (ii) That scientific theories are at least sometimes capable of being represented as interpreted formal calculi, and -/- (iii) That when theoretical terms are defined contextually, as opposed to directly, otherwise unintelligible assertions acquire scientific significance. -/- Further, it is shown that, even though Berkeley's arguments for idealism fall through, he himself deserves credit for identifying the principle in terms of which the fallacies in those arguments are to be understood, namely: -/- (*) It is not sensory experience alone that yields awareness of the outside world, but sensory experience coupled with awareness on the subject's part of relational invariances holding among the objects of those awareness. -/- Thus, perceptual knowledge is knowledge of invariances. And, to make a point hinted at in Berkeley's work, knowledge of laws is meta-perceptual knowledge, given that laws of nature are invariances holding among the invariances holding among the objects of perception.

In this paper, I argue that Constructive Empiricism (CE) is ambiguous between two interpretations: CE as a normative epistemology of science and CE as a descriptive philosophy of science. When they present CE, constructive empiricists write as if CE is supposed to be more than a normative epistemology of science and that it is meant to be responsible to actual scientific practices. However, when they respond to objections, constructive empiricists fall back on a strictly normative interpretation of CE. This (...) ambiguity seems to make CE immune to objections in a rather ad hoc fashion. (shrink)

The dissertation studies the mathematical strength of strict constructivism, a finitistic fragment of Bishop's constructivism, and explores its implications in the philosophy of mathematics. ;It consists of two chapters and four appendixes. Chapter 1 presents strict constructivism, shows that it is within the spirit of finitism, and explains how to represent sets, functions and elementary calculus in strict constructivism. Appendix A proves that the essentials of Bishop and Bridges' book Constructive Analysis can be developed within strict (...) constructivism. Appendix B further develops, within strict constructivism, the essentials of the functional analysis applied in quantum mechanics, including the spectral theorem, Stone's theorem, and the self-adjointness of some common quantum mechanical operators. Some comparisons with other related work, in particular, a comparison with S. Simpson's partial realization of Hilbert's program, and a discussion of the relevance of M. B. Pour-El and J. I. Richards' negative results in recursive analysis are given in Appendix C. ;Chapter 2 explores the possible philosophical implications of these technical results. It first suggests a fictionalistic account for the ontology of pure mathematics. This leaves a puzzle about how truths about fictional mathematical entities are applicable to science. The chapter then explains that for those applications of mathematics that can be reduced to applications of strict constructivism, fictional entities can be eliminated in the applications and the puzzle of applicability can be resolved. Therefore, if strict constructivism were essentially sufficient for all scientific applications, the applicability of mathematics of mathematics in science would be accountable. The chapter then argues that the reduction of mathematics to strict constructivism also reduces the epistemological question about mathematics to that about elementary arithmetic. The dissertation ends with a suggestion that a proper epistemological basis for arithmetic is perhaps a mixture of Mill's empiricism and the Kantian views. (shrink)

Intended for philosophically minded psychologists and psychologically minded philosophers, this book identifies the ways that psychology has hobbled itself by adhering too strictly to empiricism, this being the doctrine that all knowledge is observation-based. In the first part of this two-part work, it is shown that empiricism is false. In the second part, the psychology-relevant consequences of this fact are identified. Five of these are of special importance. First, whereas some psychopathologies (e.g. obsessive-compulsive disorder) corrupt the activity mediated (...) by one’s psychological architecture, others (e.g. sociopathy) corrupt that architecture itself. Second, the basic tenets of psychoanalysis are coherent. Third, all propositional attitudes are beliefs. Fourth, selves are minds that self-evaluate. Fifth, it is by giving our thoughts a perceptible form that we enable ourselves to evaluate them, and it is by expressing ourselves in language and art that we give our thoughts a perceptible form.

Hume sought to analyse our propositionally-structured thought in terms of our ultimate awareness of nothing but objects, sensory impressions or their imagistic copies, The ideas of space and time are often regarded as exceptions to his Copy Theory of impressions and ideas. On grounds strictly internal to Humes account of the generality of thought. This ultimately reveals the limits of the Copy Theory and of Concept Empiricism. The key is to recognise how very capacious is our (Humean) imaginative capacity (...) to associate particular perceptions by various fine-grained determinable resemblances. (shrink)

I begin chapter I by discussing two key distinctions that constitute the core of van Fraassen's constructive empiricism: a distinction between observables and unobservables and a distinction between acceptance and belief with regard to a theory. To support constructive empiricism, van Fraassen also deploys two epistemological principles: only actual observations are to be taken as evidence and possible evidence is all that can be rationally inferred from the actual evidence. I reject both principle and van Fraassen's construal of (...) observation. As does van Fraassen, I make the distinction between acceptance and belief in chapter II. I contend that one does not need to be an antirealist to espouse this distinction between acceptance and belief. ;In the remaining chapters, I develop a quasi-Bayesian account of acceptance as an alternative to van Fraassen's. In chapter III, I consider three views of acceptance: van Fraassen's, Bayesian views, and the epistemic view. I argue that both van Fraassen's account and the epistemic account are open to Bayesian objections. However, Bayesianism assumes a controversial principle called "maximization of expected utility" , which might mitigate the impact of the Bayesian objections. ;In the final chapter, I consider different decision principles, e.g. Kyburg's decision principle, and Gardenfors and Sahlin's decision principle. I formulate a decision principle called the "weak-dominance-decision principle " based on Kyburg's theory . The interval-based probability yields, as a limiting case, the point-valued probability when we have complete information about the event in question. In this case, my decision principle reduces to MEU. Therefore, the same Bayesian objections against both van Fraassen's theory of acceptance and the epistemic theory of acceptance could be made from the perspective of my decision principle while escaping the perils of strict Bayesianism. My theory of acceptance is quasi-Bayesian, because WDP rests on interval-based probability. (shrink)

Value judgments are meaningless. This thesis was one of the notorious tenets of Carnap's mature logical empiricism. Less well known is the fact that in the Aufbau values were considered as philosophically respectable entities that could be constituted from value experiences. About 1930, however, values and value judgments were banished to the realm of meaningless metaphysics, and Carnap came to endorse a strict emotivism. The aim of this paper is to shed light on the question why Carnap abandoned (...) his originally positive attitude concerning values. It is argued that his non-cognitivist attitude was the symptom of a deep-rooted and never properly dissolved tension between conflicting inclinations towards Neokantianism and Lebensphilosophie. In America Carnap's non-cognitivism became a major obstacle for a closer collaboration between logical empiricists and American pragmatists. Carnap's persisting adherence to the dualism of practical life and theoretical science was the ultimate reason why he could not accept Morris's and Kaplan's pragmatist theses that cognitivism might well be compatible with a logical and empiricist scientific philosophy.

[A] thorough definition of empiricism is no simple task. In this article, we will instead attempt an overarching exposition of two overlapping but divergent paradigms of empiricism: (a) strict empiricism, representing most of the British empiricists and ancient skeptics and (b) mitigated, or metaphysical,1 empiricism represented by Aristotle and St. Thomas Aquinas. Sense experience is the unifying departure point for both, but while (b) says that human knowledge begins with sense experience, (a) tends to ultimately (...) reduce knowledge to sense experience. Concerning structure, our article is divided into two parts. The first consists of two sections: (1) a philosophical critique of strict empiricism from the viewpoint of mitigated empiricism and (2) an account of how both versions of empiricism view causality. The second part consists of a critique of strict empiricism from the point of view of mathematics and modern physics. Since the very scope of these topics has generated a vast literature, the sole aim of our thesis can be only to raise questions about certain empiricist presuppositions that enjoy wide appeal, especially in the English-speaking world.

Despite the emergence of new forms of feminist empiricism, there continues to be resistance to the idea that feminist political commitment can be integral to hypothesis testing in science when that process adheres strictly to empiricist norms and is grounded in a realist conception of objectivity. I explore the virtues of such feminist empiricism, arguing that the resistance is, in large part, due to the lingering effects of positivism.

This is the first volume in the Vienna Circle collection. The editorial committee plans to publish a series of about thirty volumes between 1973 and 1980. This gigantic task should render immense service to both historians and contemporary philosophers. The basic aim is to present in English anthologies of "the most important work of single members, which should contain besides a detailed essay on the man a complete bibliography of his work." The present large anthology of the writings of Neurath (...) presents a valuable collection of memories, in lieu of a biographical essay, revealing Neurath’s manysided interests and activities. Of more strictly philosophical interest are the short essays that deal with the history of optics, the problem of pleasure maximum, the scientific conception of the world; and a long selection from the book Empirical Sociology: The Scientific Content of History and Political Economy.

This paper suggests that one single thread characterizes the developments of French phenomenology that occurred after 1990 in the wake of Merleau-Ponty's and Levinas's major contributions. Janicaud in 1991 had already identified one global trend in French phenomenology and believed it was possible to unite the thoughts of Levinas, Henry, Marion and Chrétien under the common banner of “theological phenomenology.” However, his analysis seems to fail to account for deeper-seated affinities that exist between French phenomenologists such as Marion, Lacoste, Chrétien, (...) Richir, Depraz, Romano – and Benoist for part of his work. This is the reason why, although the present paper does agree with Janicaud's idea that the French authors who define themselves as phenomenologists share some common ground, it defines this common trend quite differently, i.e., as a form of epistemological realism that ultimately manifests itself as a radical empiricism. Consequently, the present study will state and defend three hypotheses: contemporary French phenomenology professes a form of realism of experience, which is the true rallying point of otherwise differing elaborations; this type of epistemological empiricism, by virtue of its radicality, implies a problem that threatens to drive phenomenology towards its own dissolution, because as it precipitates in fine the dilution of philosophical discourse into a multitude of other discourses; this variant of empiricism shows that, within its strictly defined viewpoint, there is scarcely any difference between French phenomenology and a certain part of French analytical philosophy. All three hypotheses lead to the same conclusion: the determination of the defining aspect of contemporary French phenomenology entails, beyond the apparent, misleading, and futile quarrel of paradigms, to bring to light a common space for contemporary French philosophy, which, from both perspectives, can be conveyed by the single term “to show.” It is, in fact, the elevation of “to show” to the detriment of “to demonstrate” that seems to ensnare thinkers within an impasse.

How are we to connect the mechanist methodology used by Baglivi in his physiological treatises with the apparently strict empiricism that he promotes in his therapeutic work entitled Practice of Physick, reduc’d to the Ancient Way of Observations? In order to answer this question, we examine the methodological implications of the “history of diseases” that Baglivi promotes by using Bacon’s recommendations in the Novum organum. Then, we compare this result with the place that historians generally gave to Baglivi (...) in the medical context of that time: the place of a dogmatic and “iatromechanist” physician who was far from practical and therapeutic concerns. This confrontation allows us first to apprehend the polemical origin of the so-called “iatromechanism” as a historiographical label, and second, to question the preeminence of the role of observations in the shaping of the classical distinction between “rational” physicians and “empirical” ones. When Early Modern physicians use the dichotomy between “empirical” and “rationalist” in order to discredit what they perceive as oversimplification or dogmatism, there is most often a third group at stake: a group which is depicted as the providential and intelligent solution to sectarianism. For Baglivi, this third group would be an “Empirick rational sect.” The distinction between a medicina prima and a medicina secunda allows us to understand such an apparently paradoxical category.

The present paper investigates why logical empiricists remained silent about one of the most philosophy-laden matters of theoretical physics of their day, the principle of least action (PLA). In the two decades around 1900, the PLA enjoyed a remarkable renaissance as a formal unification of mechanics, electrodynamics, thermodynamics, and relativity theory. Taking Ernst Mach's historico-critical stance, it could be liberated from much of its physico-theological dross. Variational calculus, the mathematical discipline on which the PLA was based, obtained a new rigorous (...) basis. These three developments prompted Max Planck to consider the PLA as formal embodiment of his convergent realist methodology. Typically rejecting ontological reductionism, David Hilbert took the PLA as the key concept in his axiomatizations of physical theories. It served one of the main goals of the axiomatic method: ''deepening the foundations.'' Although Moritz Schlick was a student of Planck's, and Hans Hahn and Philipp Frank enjoyed close ties to Gottingen, the PLA became a veritable Shibboleth to them. Rather than being worried by its historical connections with teleology and determinism, they erroneously identified Hilbert's axiomatic method tout court with Planck's metaphysical realism. Logical empiricists' strict containment policy against metaphysics required so strict a separation between physics and mathematics to exclude even those features of the PLA and the axiomatic method not tainted with metaphysics.

In a reply to Marga Vicedo the philosophical inconsistency of Morgan is emphasized. It is argued that even if a strict classification of scientists according to their philosophical position is not possible, their science may still be influenced by their philosophical ideas. Finally it is suggested that philosophical ideas influence science less by a direct effect on the scientists than indirectly through science policy and administration.

Otto Neurath’s empiricist methodology of economics and his contributions to politi- cal economy have gained increasing attention in recent years. We connect this research with contemporary debates regarding the epistemological status of thought experiments by reconstructing Neurath’s utopias as linchpins of thought experiments. In our three reconstructed examples of different uses of utopias/dystopias in thought experiments we employ a reformulation of Häggqvist’s model for thought experiments and we argue that: (1) Our reformulation of Häggqvist’s model more adequately complies with many (...) uses of thought experiments, especially with the open-ended discussions of utopias and dys- topias in thought experiments. (2) As a strict logical empiricist, Neurath is committed to a strictly empiricist account of thought experiments. John Norton’s empiricist argument view can indeed account for the justifications of empirical beliefs and genuine discoveries targeted by scientific utopianism in three distinct (yet connected) ways, all of which Neur- ath already contemplated: (2.I) Dealing with utopias and thought experiments on a regular basis increases creativity and inventiveness. (2.II) Particular ways of presenting knowl- edge facilitate scientific discovery and social progress. (2.III) The use of utopias in thought experiments can prompt conceptual change and allow access to new phenomena. We con- clude by highlighting that, even though thought experiments support a positive attitude for exploring new social possibilities, Neurath points out that active decisions are unavoidable. The exploration of alternatives and the awareness of a need for decisions in policy discus- sion avert a technocratic outlook in social science. (shrink)

As the debate between realists and empiricists in the philosophy of science drags on, one point of consensus has emerged: no one wants to be a manifestationalist. The manifestationalist is a kind of radical empiricist who argues that science provides theories that aim neither at a true picture of the entire world, nor even an empirically adequate picture that captures the world in all its observable respects. For manifestationalists, science aims only at providing theories that are true to the observed (...) aspects of reality. If the guiding idea of empiricism is that experience, and experience alone, provides us with knowledge about the world, then manifestationalism is an exceptionally strict empiricist perspective on science. Manifestationalism has primarily served within a reductio: certain empiricist views and arguments, when taken to their logical conclusion, lead to manifestationalism and so cannot be correct. The reductio works only because manifestationalism is widely agreed to be a non-starter. However, this consensus against manifestationalism is based on a single argument. We contest this assessment of manifestationalism and show that the primary argument against manifestationalism fails to hit its target. We do not intend to offer a manifesto for manifestationalism. Rather, we aim to vindicate it from a false accusation. Manifestationalism may not be the correct view of science, but the objections levied against it so far can be met. (shrink)

While we share many of the views on emotion research put forth in Kagan’s article “Once More into the Breach,” our commentary focuses on two points of disagreement. First, we argue for the importance of a priori principles. In particular, emotions cannot be understood without reference to final and formal cause, and the related principles of equifinality and equipotentiality. Secondly, although we agree the term “basic emotions” is misleading, we maintain that the emotions traditionally called “basic” should still be seen (...) as a distinct set of emotions by virtue of their being constitutive for other, derived emotions. In conclusion we argue for moving beyond the strict empiricist approach proposed by Kagan and many thinkers before him. (shrink)

In their recent “A modest defense of manifestationalism” (2015), Asay and Bordner defend this position from a quite famous criticism put forward by Rosen (1994), according to which while manifestationalism can be seen as more compatible with the letter of empiricism than other popular stances, such as constructive empiricism, it fails nonetheless to make sense of science. The two authors reckon that Rosen’s argument is actually flawed. In their view, manifestationalism could in fact represent a legitimate thesis about (...) the nature of scientific inquiry. In this paper, I will show that Asay and Bordner’s criticisms to Rosen are actually off target. Moreover, they rest upon an understanding of what the aim of science is that might serve to their purposes, but that does not seem to be in line with the scientific enterprise. Perhaps constructive empiricism still represents the best compromise so far presented between strict empiricism and the acknowledgment of the rationality of science. (shrink)

Several lines of argument support the notion that the legacy of positivism (if cast in terms of the realist/instrumentalist debate) is more realist than not. Work by Joia Lewis and Alberto Coffa on both Schlick and Carnap is cited, and contemporary work from Van Fraassen and Boyd briefly alluded to. Note is made of the differences within contemporary realist theory, and it is included that Carnap's essay "Empiricism, Semantics and Ontology" is crucial for resolution of the debate. In closing (...) it is noted that the spirit of much of the original positivist work reinforced the contention than those who work within the framework of science do in fact accept the reality of key scientific entities.

In lieu of an abstract, here is a brief excerpt of the content:The Concept of Experience in Locke and Hume JOHN W. YOLTON THE EMPIRICISTPROGRAM has been designed to show that all conscious experience "comes from" unconscious encounters with the environment, and that all intellectual contents (concepts, ideas) derive from some conscious experiential component. Some empiricists, but not all, have also argued that experience reports about the world. A strict empiricism would have to reject this latter claim, as (...) Hume did, although even to consider the possibility of knowledge being related to an external world is to operate on a reflective level, to seek to make sense of experience. The distinction between an account of the nature of experience--its structure, relations, and contents-and explanations of experience--its causal antecedents, its reference--is an important one. The phrase "the concept of experience" refers to the use made of some account of experience. The concept of experience need not be restricted to the experiential contents. Thus, Locke sought to show how experience is of the world, Hume tried to show how experience restricts our valid conceptual contents to certain sorts of ideas, eliminating others. Any account of experience will already be a conceptualization of experience: it must be made from the reflective level. But the account need be no more than a careful record of how the organism comes to the conscious level. Of course, such an account cannot be a straightforward description, since we cannot directly observe all of the processes operating in the production of awareness. The psychology of awareness is forced to extrapolate and conjecture. Nevertheless, we can still distinguish the psychological or descriptive account of experience from the metaphysical use made of that account. It is my purpose here to explore the accounts given and the uses made of experience by two representative empiricists, that is, by philosophers whom we look upon as advancing the empiricist metaphysic of experience. Locke's Derivation o[ Ideas From Experience Locke claimed that all mental contents come from two sources, sensory experience of the world and introspective awareness of our mental processes. The program of Book II of his Essay was to exemplify, by reference to a [53] 54 HISTORY OF PHILOSOPHY number of different ideas and concepts, this derivation of our mental contents. The counter claim for Locke was innatism, the view held by many of his contemporaries and refuted in the first book of his Essay. In order to appreciate what Locke's alternative to innatism was, we must try to discover what the program of derivation of ideas amounts to in his epistemology and what precisely he understood by the term "experience." We must first note that he offers the program of derivation in conjunction with a complex theory of mental operations. H. H. Price has remarked that it is "historically false that the empiricist thought the human mind passive. It would be more just to criticize them for making it more active than it can possibly be.''1 Mental processes play a most active and decisive role in the genesis of all ideas in Locke's account. In the case of simple ideas of sense even, the mind must be attentive to what the senses report, else that report will go unrecorded, or be recorded only at the neural level (II, I, #6, #8, and II, IX, #3). Locke frequently draws the distinction between mental contents or processes and physical processes. In the "Epistle to the Reader," where he defines "idea," he is careful to distinguish idea from the sound we "use as a sign of it." In I, I, #2 he draws a distinction between the "physical consideration of the mind" and the non-physical consideration, although he does not have a name for the latter. He also speaks there of "sensations by our organs" and "ideas in our understanding." Locke disclaimed any intention of going into the physical account of sensation. He simply accepted the current corpuscular theory. But although he is not always as precise as we would be about the physical and physiological levels of encounter, in distinction from the mental levels, he does hold to this division. II, I, #3, for instance, speaks of the senses conveying "into the mind" several "distinct perceptions... (shrink)

Empiricism is a claim about the contents of the mind: its classic slogan is nihil est in intellectu quod non fuerit in sensu, ‘there is nothing in the mind (intellect, understanding) which is not first in the senses’. As such, it is not a claim about the fundamental nature of the world as material. I focus here on in an instance of what one might term the materialist appropriation of empiricism. One major component in the transition from a (...) purely epistemological claim about the mind and its contents, to an ontological claim about the nature of the world, is the new focus on brain-mind relations in the eighteenth century. Here I examine a Lockean trajectory as exemplified in Joseph Priestley’s 1777 Disquisitions Relating to Matter and Spirit. But Locke explicitly ruled out that his inquiry into the logic of ideas amounted to a ‘physical consideration of the mind’. What does it mean, then, for Priestley to present himself as continuing a Lockean tradition, while presenting mental processes as tightly identified with ‘an organical structure such as that of the brain’ (although he was not making a strict identity claim as we might understand it, post-Smart and Armstrong)? One issue here is that of Priestley's source of ‘empirical data’ regarding the correlation and indeed identification of mental and cerebral processes. David Hartley’s theory in his 1749 Observations on Man was, as is well known, republished in abridged form by Priestley, but he discards Hartley's 'vibratory neurophysiology' while retaining the associationist framework, although not because he disagreed with the former. Yet Hartley was at the very least, strongly agnostic about metaphysical issues (and it is difficult to study these authors while bracketing off religious considerations). One could see Locke and Hartley as articulating programs for the study of the mind which were more or less naturalistic (more strongly so in Hartley’s case) while avoiding ‘materialism’ per se; in contrast, Priestley bit the (materialist) bullet. In this paper I examine Priestley’s appropriation and reconstruction of this ‘micro-tradition’, while emphasizing its problems. (shrink)

In the first Enquiry, Hume takes the experience of exerting force against a solid body to be a key ingredient of the vulgar idea of power, so that the vulgar take that experience to provide us with an impression of power. Hume provides two arguments against the vulgar on this point: the first concerning our other applications of the idea of power and the second concerning whether that experience yields certainty about distinct events. I argue that, even if we accept (...) Hume’s conception of the vulgar’s approach, neither of Hume’s arguments succeeds. The first argument can be resisted either by using the very arguments Hume provides concerning other causal representations or by simply rejecting Hume’s strict empiricism. The second argument can be resisted on epistemological grounds: there is no reason to think that an experience of a maximally-strong metaphysical connection would provide a maximally-strong epistemological connection. Unlike some recent neo-Anscombean responses to the second argument, my response does not require challenging Hume’s view that causal relations are strictly necessary. Though I do not attempt to translate the resilience of the vulgar view into contemporary terms, the failure of Hume’s arguments challenges one of the long-standing motivations for Humean approaches to causation.

William James criticizes Hume for failing to adhere to the strictly empiricist method when he postulates discrete constituents of experience—which Hume calls perceptions—thereby making our experience a train of disconnected pieces. James argues that the discontinuity of experience in Hume results in part from his failure to recognize the immediate presence of relations in experience.1 Emphasizing a continuity and unity of experience, James thus differentiates his empiricism from Hume's as being radical in the sense that it recognizes relations as (...) 'real' parts of experience just as are things that are experienced to be so related.2 This raises a question concerning the experiential status of relations in Hume: is .. (shrink)

Nineteenth-century scientist Hermann von Helmholtz’s peculiar wavering between empiricism and transcendentalism in his philosophy of science in general, and in his theory of perception in particular, is a much debated and well-documented topic in the history and philosophy of science. This contribution aims at providing a fresh angle on this classical issue, by considering Helmholtz’s account of differential consciousness against the background of a centuries-old philosophical debate between the empiricist tradition and the tradition of transcendental idealism. By placing Helmholtz’s (...) psychology against the background of a historical narrative stretching from Hume to Fichte, one can gain insight into the possible merits of his empirico-transcendentalism with regard to the problem of differentiation. More particularly, it is argued that Helmholtz’s psychology tilted towards transcendentalism when met with the classical theoretical problems of strict empiricism in dealing with the foundation of consciousness, most notably circularity and infinite regress. Without claiming that Helmholtz’s theorizing presented a self-conscious attempt to overcome the latter issues, his well-known wavering between perspectives in general, and his appropriation of the a priori in particular, might have served him well in avoiding the deadlocks of empiricism. As noted at the end, however, Helmholtz’s account produced complex philosophical problems of its own. (shrink)

The most immediate reason why chemists are unenthusiastic about the philosophy of science is the historic hostility of important philosophers, to the concept of atoms. (Without atoms, discovery in chemistry would have proceeded with glacial slowness, if at all, in the last 200 years.) Other important reasons include the anti-realist influence of the philosophical dogmas of logical positivism, instrumentalism, of strict empiricism. Though (as has been said) these doctrines have recently gone out of fashion, they are still very (...) influential.A diagram of the methodology of experimental research is proposed, in the form of a flow sheet, with feedback. The model is developed as a multi-level expansion of a diagram of the hypothetico-deductive model. It recognizes that strong mutual support, or interlocking, of research endeavors is important, at the underlying level or levels where explanatory causation contributes to scientific understanding. (Mutual support at the laboratory level is generally weak or trivial.)

Examples from Archimedes, Galileo, Newton, Einstein, and others suggest that fundamental laws of physics were—or, at least, could have been—discovered by experiments performed not in the physical world but only in the mind. Although problematic for a strict empiricist, the evolutionary emergence in humans of deeply internalized implicit knowledge of abstract principles of transformation and symmetry may have been crucial for humankind's step to rationality—including the discovery of universal principles of mathematics, physics, ethics, and an account of free will (...) that is compatible with determinism.

William James criticizes Hume for failing to adhere to the strictly empiricist method when he postulates discrete constituents of experience — which Hume calls perceptions — thereby making our experience a train of disconnected pieces. James argues that the discontinuity of experience in Hume results in part from his failure to recognize the immediate presence of relations in experience. Emphasizing a continuity and unity of experience, James thus differentiates his empiricism from Hume's as being radical in the sense that (...) it recognizes relations as ‘real’ parts of experience just as are things that are experienced to be so related. This raises a question concerning the experiential status of relations in Hume: is James correct in accusing Hume of failing to notice the experiential reality of relations? Does Hume deny the experiential reality of relations entirely? Or does Hume downplay the experiential reality of relations and come to take them merely as products of the imagination, hence not ‘real,’ for certain theoretical reasons? (shrink)

The most immediate reason why chemists are unenthusiastic about the philosophy of science is the historic hostility of important philosophers, to the concept of atoms. (Without atoms, discovery in chemistry would have proceeded with glacial slowness, if at all, in the last 200 years.) Other important reasons include the anti-realist influence of the philosophical dogmas of logical positivism, instrumentalism, of strict empiricism. Though (as has been said) these doctrines have recently gone out of fashion, they are still very (...) influential.A diagram of the methodology of experimental research is proposed, in the form of a flow sheet, with feedback. The model is developed as a multi-level expansion of a diagram of the hypothetico-deductive model. It recognizes that strong mutual support, or interlocking, of research endeavors is important, at the underlying level of levels where explanatory causation contributes to scientific understanding. (Mutual support at the laboratory level is generally weak or trivial.)

The aim of this dissertation is to explore a central aspect of Berkeley's philosophy of science, namely, his philosophical account of the status of Newton's mechanics. In De Motu, Berkeley's treatise on mechanics, he makes plain that he accepts Newton's mechanics as an excellent scientific theory, while refusing to admit the existence of physical forces. Thus, Berkeley is an anti-realist about Newtonian mechanics. In the dissertation, I seek to identify the grounds and nature of this anti-realism. ;Although Berkeley's motivations for (...) maintaining dynamical anti-realism are largely metaphysical , Berkeley's case against realism in De Motu does not presuppose an immaterialist metaphysics. Rather, his main argument in De Motu is based on a strict empiricism and a claim about the conceptual requirements for reference. Essentially, Berkeley maintains that we can't understand dynamics realistically because we lack any appropriate concepts of force, nor can we acquire any, given the sort of things that forces are supposed to be. Other ways in which Berkeley impugns dynamical realism in De Motu reveal interesting affinities between his position and Cartesianism. ;Berkeley's alternative to realism is, I argue, a sort of instrumentalism. Here I disagree with a number of commentators who have seen Berkeley as a reductionist, that is, someone who claims that dynamics is reducible to kinematics. I develop my interpretation of Berkeley's dynamical instrumentalism by showing how it is connected in important ways with his views about the aims of science and about the significant of action-guiding language. In conclusion, I contrast Berkeley's instrumentalism about forces with his realism about particles in Siris. (shrink)

Newton and Einstein each in his way showed us the following: an epistemologically responsible physicist adopts the most measured understanding possible of spacetime structure. The proper way to infer a doctrine of spacetime is by a kind of measuring inference -- a deduction from phenomena. Thus it was (I argue) by an out-and-out deduction from the phenomena of inertiality (as colligated by the three laws of motion) that Newton delineated the conceptual presuppositions concerning spacetime structure that are needed before we (...) can actually think coherently about these phenomena. And Einstein (I argue) very much recapitulated this argument pattern, twice over in fact, recolligating the phenomena first so as to add something from the laws of electromagnetism, and then so as to add everything about gravitation, into what he understood by inertiality. Notably, to deduce one’s theoretical conclusions from phenomena is both more cautious and more cogent than to "infer to the best explanation". And in the context of the development of a doctrine of spacetime, deductions from phenomena lay before us formal rather than causal understanding. Deductions from phenomena tell us, in this context, not what things or what causes there are, but rather what our concepts should be like. The more measured the inference is, however, the more definitively it tells us this. For these reasons the most measured understanding of spacetime lies on a line between conventionalism and realism, between relationalism and absolutism, and indeed (as I demonstrate) between empiricism and rationalism. Spacetime is understood as neither merely immanent in material goings-on, nor truly transcendent of them either. In order to explain this understanding as adequately as I can and in order to remark its excellences most fully, I consider some respects in which the tertium quid between metaphysical realism and strict empiricism about spacetime is wise in the sense of practical wisdom. The wisest understanding of spacetime illustrates, I argue, an original and fundamental connection that epistemology has with ethics. (shrink)

In the Appendix to A Treatise of Human Nature, Hume famously retracts his account of personal identity by confessing that it involves a profound problem he cannot solve, which I have elsewhere identified and called the Bundling Problem. Neither of the two possible solutions that Hume himself considers in the Appendix is a viable option for him by his own lights, which might suggest that any successful account of a unified self must go beyond the empirical framework. In this paper, (...) I argue that we can find a strictly empiricist solution to Hume's problem in William James. I attempt to show that James's descriptions of our experience are phenomenologically more detailed and faithful to how experience is undergone from the first-person perspective, which allows him to explain our belief in an identical, unified self solely on empirical grounds. James finds unity and continuity right in the content of the stream of experience itself. A detailed investigation of James's accounts reveals that Hume's fundamental problem does not stem merely from his lack of empirical resources but, more importantly, from his tacit abandonment of the professed empiricist methodology.

This book adds to the growing literature on thought experiments. There are numerous examples drawn from the sciences and philosophy. The principle claim is that thought experiments are a limiting case of real experiments. It is a moderate empiricist view, in contrast to, e.g., the Platonism of Brown or the strict empiricism of Norton. Highly recommended.

Hans Hahn, mathematician, philosopher and co-founder of the Vienna Circle, attempted to reconcile the validity and applicability of both logic and mathematics with a strict empiricism. This article begins with a review of this attempt, focusing on his view of the relation of language to logic and his answer to the question of why we need logic. I then turn to some recent work by Stephen Yablo in an attempt to show that Yablo's fictionalism, and in particular his (...) use of metaphor, can shed light on Hahn's philosophy of logic. (shrink)

Some strongly empiricist views of scientific knowledge advocate a rejection of metaphysics. On such views, scientific knowledge is described strictly in terms of knowledge of the observable world, demarcated by human sensory abilities, and no metaphysical considerations need arise. This paper argues that even these views require some recourse to metaphysics in order to derive knowledge from experience. Central here is the notion of metaphysical inference, which admits of different “magnitudes”, thus generating a spectrum of putative knowledge with more substantially (...) empirical beliefs at one end, and more metaphysically imbued beliefs at the other. Given that metaphysical inference is required even concerning knowledge of the observable, the empiricist hope of avoiding metaphysics altogether is futile: knowledge of the observable simply involves metaphysical inferences that are of smaller magnitudes than others. Metaphysical inferences are required not only to distinguish veridical from non-veridical experience and to determine the quality of empirical information, but also in order to explain how we construct experience (through categorizations and classifications of objects, events, processes, and properties), how we extrapolate from empirical evidence to generalize about observable phenomena, and how we use this evidence to test and confirm hypotheses and theories.

Epistemological disputes in the philosophy of science often focus on the question of how restrained or expansive one should be in interpreting our best scientific theories and models. For example, some empiricist philosophers countenance only belief in their observable content, while realists of different sorts extend belief (in incompatible ways, reflecting their different versions of realism) to strictly unobservable entities, structures, events, and processes. I analyze these disputes in terms of differences regarding where to draw a line between domains in (...) which one has warrant for belief and those in which one should suspend belief and thus remain sceptical. I consider and defend the idea that the precise location of this line is subject to a form of epistemic voluntarism, and argue that a Pyrrhonian reading of the basis of such voluntaristic choice is both natural and transformative of our understanding of these debates.

Ever since David Hume, empiricists have barred powers and capacities from nature. In this book Cartwright argues that capacities are essential in our scientific world, and, contrary to empiricist orthodoxy, that they can meet sufficiently strict demands for testability. Econometrics is one discipline where probabilities are used to measure causal capacities, and the technology of modern physics provides several examples of testing capacities (such as lasers). Cartwright concludes by applying the lessons of the book about capacities and probabilities to (...) the explanation of the role of causality in quantum mechanics. (shrink)

Mainstream philosophy of science has embraced an “empiricist” approach to scientific method. To be slightly more precise, I venture that most philosophers of science today would endorse the view that experience is the source of most scientific knowledge. The aim of this essay will be to challenge the consensus, by showing how we cannot and should not abandon all elements of the “rationalist” tradition, a tradition often identified with philosophers such as Descartes. There are several elements frequently identified with “rationalist” (...) science (Stump, 2005): questioning of sense experience, the attempt to rethink the “metaphysical” foundations of one’s science, using either thought experiment, or appealing to demonstrative arguments purporting to establish ‘necessary’ truths, often using either mathematics or geometry, and appeal to “virtues” not usually considered “strictly empirical,” such as simplicity. This essay explores the effective deployment of such considerations in the history and current practice of science. (shrink)

Pragmatic encroachment theories of knowledge may be characterized as views according to which practical factors may partly determine the truth-value of ascriptions that S knows that p – even though these factors do not partly determine S’s belief that p or p itself. The pros and cons of variations of pragmatic encroachment are widely discussed in epistemology. But despite a long pragmatist tradition in the philosophy of science, few efforts have been devoted to relate this particular view to issues in (...) philosophy of science. Consequently, a central aim of the present paper is to consider how the contemporary debates over pragmatic encroachment connect to philosophy of science. More specifically, I will set forth some arguments against the idea of pragmatic encroachment on scientific knowledge. Moreover, I will argue that it is not plausible to respond to these arguments by embedding pragmatic encroachment in the anti-realist framework of constructive empiricism. So, I conclude that there are good reasons to reject pragmatic encroachment theories of scientific knowledge. (shrink)
