Laboratory science is our only source of knowledge about the world as it is apart from our perceptions of the world. Empiricist philosophy, relying on evidence consisting in human perceptions, can only give us knowledge of phenomena making up the world-perceived, which recent neuroscience tells us is wholly and entirely constructed by our neuron-based human perceptual apparatus. In this light, empiricist philosophy should explicitly and fundamentally be reconceived as a method of thinking critically about phenomena, i.e. as a stripped down, (...) fallibilist, non-foundationalist version of “phenomenology”. I also describe implications of these proposals for thinking critically about and conceptualizing phenomena like the Cartesian “I”-that-thinks, consciousness, mind, personal identity, free will, and causal relationships between the brain and the conscious “I.”.

Broadly speaking, “empiricism” is a label that usually denotes an epistemological view that emphasizes the role that experience plays in forming concepts and acquiring and justifying knowledge. In contemporary philosophy, there are some authors who call themselves as empiricists, although there are differences in the way they define what experience consists in, how it is related to theory, and the role experience plays in discovering and justifying knowledge, etc. (e.g., Ayer 1936; Van Fraassen 2002). In contrast, in the early (...) modern period, empiricism was not a label that philosophers traditionally characterized until nowadays as empiricists (most famously, John Locke, George Berkeley, and David Hume) used to describe their doctrines. Indeed, as attributed to early modern philosophical authors, empiricism is not an actor’s category, but an analytic historiographical category retrospectively applied to them and confronted to rationalism, whose main representatives were considered to be Rene Descartes, Baruch Spinoza, and G.W. Leibniz. Such a narrative began to be established by the late nineteenthcentury and described early modern empiricism as an epistemological stance maintaining (1) that the origin of all mental contents lies in experience (a genetic statement), and (2) that knowledge can only be justified a posteriori (an epistemic statement). This entails that empiricists deny the existence of innate mental contents and the possibility of a purely a priori knowledge. In the history of early modern science such a dichotomy has been usually rendered in terms of the opposition between continental rationalist Cartesian science vs British empiricist Newtonian science. In the last four decades, many aspects of this traditional narrative have been criticized, and the meaning of early modern empiricism is subject of renewed studies. (shrink)

We reply to Philippe Depoortère’s paper “On Ricardo’s method: The Unitarian influence examined. Some comments on Cremaschi and Dascal’s article ‘Malthus and Ricardo on Economic Methodology’”. Depoortère asks two questions: (1) was Ricardo’s ‘conversion’ to Unitarianism sincere? (2) did Ricardo follow the methodologies of Priestley and Belsham? His answers are that he was a ‘religious skeptic’ and he was not an ‘empiricist’ like Priestley and Belsham. We reply that the sincerity of Ricardo’s religious beliefs is irrelevant since we start with (...) the evidence that he was exposed for a long time to the intellectual influence of Belsham, primarily in matters of philosophy, and to deny this would imply a negative answer to a different question, namely, did Ricardo attend Unitarian meetings for 15 years? Then we reply that Ricardo inherited Belsham’s version of Newtonian methodology which omitted the fourth rule, that is the most anti-Cartesian and anti-systematic rule, and this has little to do with empiricism but instead with apriorism.

I discuss Mary Hess’s interaction-view of scientific metaphor, outline an alternative view and show how it may prove fruitful when applied to chapters of the history of science. I start with a reconstruction of the discussion on the nature of scientific models and on their relationship to metaphors that has taken place in the Anglo-Saxon philosophy of Science starting from the Fifties; the discovery started with Stephen Pepper and Kenneth Burke, reaching Thomas Kuhn, Marx Wartofsky, and George Lakoff via Max (...) Black's and Mary Hesse's interaction view. I argue that Hesse's view has a number of weak points: uncritically accepting Black's idea of "interaction", for keeping too much of a logical empiricist view of observation language, and for keeping too much of a Scholastic distinction between formal and material analogy. I argue that a few insights from Kuhn and Wartofsky seem to go in the same direction as Granger's view of metaphor as opposed to metonymy, thus severing the link between metaphor and the "qualitative". I argue that the Cartesian legacy and its implicit ideal of a "mirroring" relationship between the world and the mind is the main obstacle to be eventually overcome if we are to work out a satisfactory account of the language of science and that suggestions from pragmatism as well as from French epistemology may be used in order to work out a post-Cartesian view of science.

The Système de philosophie by Pierre Sylvain Régis can be considered as the achievement both of the scientific liveliness of the Académie des Sciences in the 17th century and of its fruitful relationship with the Royal Society. Since it aims to shape the new conception of the universe in terms of a system, the Système represents one of the most mature achievements of Cartesian philosophy and it is characterized by an empirical interpretation of Descartes’ thought. The Système therefore reflects (...) two important phenomena occurring in the Europe of the 17th century: the scientific revolution and the proliferation of Academies. In fact, this ambitious work could be undertaken with the support of the Académie des Sciences and the Journal des Sçavants. My paper will analyse the French context by focusing to outline the role which the Académie de France had both in France, as the medium of dissemination of the new philosophy despite censorship, and abroad, in particular through the relationship with the Royal Society in England. I aim to analyse the role of the Journal des Sçavants as a means to share ideas other than by correspondence and as a trait d’union between “rationalist France” and “empiricist England”. I intend to question whether it is possible to establish a connection between the empirical interpretation of French Cartesianism, the consolidation of the Académie de France and the employment of new means of academic communication. The paper will show that the second half of 17th century France represents a remarkable exception to the conventional picture, which states that in 17th century Europe, following the success of a mechanistic interpretation of reality, two philosophical school clashed: rationalism, predominating on the continent, and empiricism, in England.

The conception of a ‘law of nature’ is a human product. It was created to play a role in natural philosophy, in the Cartesian tradition. In light of this, philosophers and scientists must sort out what they mean by a law of nature before evaluating rival theories and approaches. If one’s conception of the laws of nature is yoked to metaphysical notions of truth and explanation, that connection must be made explicit and defended. If, on the other hand, one’s (...) aim is to disentangle laws from truth or from explanation, that must be stated and defended as well. If philosophers do not make such assumptions, intuitions, and methodological commitments clear, then it will be impossible to identify the source of disagreement in debates about the laws of nature. Are the conflicts rooted in disagreement about the conclusions reached, or do the background commitments of the combatants block any resolution to the dispute in principle or in practice? (shrink)

The growth of knowledge has always included opposing worldviews and clashes of distinct interests. This includes different rationalities which either have served or disserved the State. A Copernican world defied the Catholic Church. Cartesian philosophy and Newtonian physics incited a major split between an allegedly knowing subject and external realities. As an outcome, many dualisms emerged: subjectivity/objectivity, particular/universal, etc. Hegelian dialectics elaborated such approach to its most extreme. The pretension of social science to be value-free assumed a neutral observer (...) collating external facts. Yet both Hume and Adam Smith challenged Descartes cogito as banal, stressing that it is not because we think that we are but rather than how we think is who we have become through the values, dispositions and beliefs that we have consciously or less than consciously acquired from life experience, and that no perception is neutral. Hume anticipated Bourclieu both on habItus and also on reflexivity in his concept of the reflexive mind" yet this then was lost by the presumption, such as by Bertrand Russell, that Hume was a "mere empiricist". Logical positivism then claimed that an appeal to 'facts' could dismiss metaphysics, invoking the logical atomism of Russell and the early Wittgenstein. But which Wittgenstein transcended not in the sense of transcendental metaphysics, though he was deeply influenced by Schopenhauer, but - after a road to Damascus encounter with Sraffa - coming to realise that meanings depend on context and that their context needs to be understood. Which we suggest in this paper is that these issues are highly relevant to the troubled relationship between rationality - or rationalities - and the State. (shrink)

This contribution aims to present the different philosophical interpretations of Descartes and Cartesian philosophies in the 17th century within the Revue Internationale de Philosophie. Studies on Descartes and Cartesian philosophies profoundly influenced the scientific orientations of the Revue by promoting the encounter between historical-philosophical and epistemological research. By reconstructing a century of Cartesian interpretations in the Revue, from the 1930s to the present day, the contribution examines the link between the universality of philosophical ideas and the analysis (...) of texts, between the history of ideas and the history of philosophical systems.

Henri Lelevel’s La philosophie moderne par demandes et réponses is a very interesting as well as pretty neglected attempt to disseminate the new philosophy among a larger audience, including the non specialists. Either the style of presentation or the oversimplification of the topics discussed is clearly intended to reach people interested to a smattering of philosophy. More than the comparisons between the traditional and the new philosophy and the compendia, this work vouches for the great interest toward the new philosophy. (...) In this particular case the model is the philosophy of Malebranche, whose interpretation of Descartes thought is preferred by Lelevel, worried by the excessive twist given toward empiricism in P.-S. Régis rendering of Cartesian philosophical system. Lelevel’s logic is directed to eliminate the confusion between sense data and knowledge, echoing also Malebranche’s notion of éténdue idéale, one of the major contribution to the reconsideration of Descartes’ thought. This paper aims to sketch the mains topics discussed in the four sections of Lelevel’s work, with some cross-references to Malebranche’s writings. (shrink)

From the second half of the last century, there has been a widespread view in the Anglophone world that Kant’s transcendental deduction (aka TD) aims to vindicate our common-sense view of the world as composed of public and objective particulars against some unqualified forms of skepticism. This widespread assumption has raised serious doubt not only about the success of TD but also about the very nature of its argument in both editions of the Critique. Yet, if there is a connection (...) between TD and global skepticism, the intriguing question is: Who is this skeptic? According to Strawson, “the skeptic” is a hypothesis of a purely sense-datum experience. In contrast, the fact that TD turns on the key notion of self-consciousness has induced several other scholars to assume that the skeptic is no none but a Cartesian external-world skeptic. None of those readings find textual support or are compatible with the very structure of the first Critique. The question is: Does this mean that TD aims only to undermine empiricism, as Guyer suggests? I do not believe so. I am pretty convinced that TD addresses a peculiar form of global skepticism, namely “Hume’s challenge to reason.” Assuming that we cognize (erkennen) and experience (erfahren) appearances as objects as a requirement of Newtonian physics, TD aims to provide a justification of the principle that nature is uniform that is superior to Hume’s justification.

This volume takes cue from the idea that the thought of no philosopher can be understood without considering it as the result of a constant, lively dialogue with other thinkers, both in its internal evolution as well as in its reception, re-use, and assumption as a starting point in addressing past and present philosophical problems. In doing so, it focuses on a feature that is crucially emerging in the historiography of early modern philosophy and science, namely the complexity in the (...) production of knowledge. The book explores the applicability of this approach to a long-considered armchair philosopher, namely René Descartes, who is now more and more understood as a full-blown scientist, networker, and intellectual éminence grise rather than as the mere philosopher of the cogito, as well as the originator of different ‘Cartesianisms’ which encompassed many ideas and approaches for long captured by dichotomic historiographical categories as rationalism and empiricism, or speculative and experimental philosophy. The essays gathered in the volume aim to address the ways in which Descartes’s philosophy evolved and was progressively understood by scientists, philosophers, and intellectuals from different contexts and eras, either by considering direct interlocutors of Descartes such as Isaac Beeckman and Elisabeth of Bohemia, early modern thinkers who developed upon his ideas and on particular topics as Nicolas Malebranche or Thomas Willis, those who adapted his overall methodology in developing new systems of knowledge as Johannes Clauberg and Pierre-Sylvain Régis, and contemporary thinkers from continental and analytic traditions like Emanuele Severino and Peter Strawson.

This dissertation articulates our human capacity to judge as a capacity for knowledge, specifically for empirical knowledge, and for knowledge of itself as such. I interpret and draw on the account of such knowledge presented by Kant’s Critique of Pure Reason, situate this account historically, and relate it to relevant contemporary debates. The first chapter motivates my project by assessing the insights and shortcomings of Cartesian epistemology. I argue that while Descartes draws on the essential self-consciousness of judgement to (...) show that the cogito is knowledge, he fails, by his own standards, to secure this status for any judgement beyond the cogito. I conclude that self-consciousness alone is empty, but that, since we can judge beyond the cogito, judgement can be given content from elsewhere. The next chapter evaluates the empiricist doctrine that operations of the senses by themselves give content to judgement and can vindicate it as empirical knowledge. I contend that Kant deepens Hume’s finding, that empiricism fails to enable us to explain empirical knowledge, into the more radical insight that empiricism fails to enable us to understand the senses as providing any content. I conclude that the senses alone are blind and that our account of empirical knowledge must privilege neither sensory givenness nor intellectual self-consciousness. The third chapter contrasts two readings of Kant on the cooperation between sensibility and understanding in empirical knowledge. I argue, against many Kantians, that the Transcendental Deduction shows that instead of understanding this cooperation compositionally – so that operations of sensibility are intelligible independently of acts of the understanding – we must conceive of it hylomorphically – so that the operations of sensibility and understanding constitute the mutually dependent matter and form of empirical knowing respectively. The final chapter substantiates this hylomorphism by explicating the form of knowledge as synthesis. Following Kant, I argue that inference is a species of synthesis and provide a synthetic explanation of inference. The resulting account simultaneously illustrates synthesis, addresses a prominent contemporary problem regarding the nature of inference, and explains how our capacity to know provides not just isolated glimpses of empirical reality, but a unified conception of it.

The editor's introduction discusses Clarence I. Lewis's conceptual pragmatism when compared with post-empiricist epistemology and argues that several Cartesian assumptions play a major role in the work, not unlike those of Logical Positivism. The suggestion is made that the Cartesian legacy still hidden in Logical Positivism turns out to be a rather heavy ballast for Lewis’s project of restructuring epistemology in a pragmatist key. More in detail, the sore point is the nature of inter-subjectivity. For Lewis, no less (...) than for the Logical Positivists at the time of the Protocols Controversy and Husserl in the Cartesian Meditations, this is a problem without a solution. The reason is that all these philosophers are apparently unable to realize that the existence of a plurality of knowing subjects cannot be treated at once both as a speculative problem and a methodological one. Lewis, thanks to his pragmatist approach both comes closer to the right answer and offers an even more naïve unsatisfactory solution to the pseudo-problem under discussion. The fact that he has clear in mind that inter-subjectivity means not only a plurality of linguistic utterances but also a co-existence of different kinds of practical behaviour. Eventually, the very idea of mind, the key-idea in the book, suffers from the above mentioned tension. In fact, if inter-subjective communication and action is considered at a methodological level, the very idea of mind would not need an analysis, and no kind of ‘reflexive’ analysis. Methodology might be limited to a ‘naïve’ level where the existence of the world and a plurality of subjects be taken as a bedrock of uncritically accepted evidence. Philosophical reflection on ultimate evidence, instead, would take a different approach, maybe the one Wittgenstein was putting into practice in the same years when Mind and the world order was written, namely it would be bound to question the very meaning of the idea of ‘mind’ as an undue fiction – the same carried out by Descartes – when he assumed the Cogito to be at once a body of self-evident truths and a thing or substance, the familiar Platonic idea of psyche or soul.

One of the most mature achievements of the Cartesian philosophy is the aim to diffuse Descartes’ thought among a wider audience by presenting his philosophy in an encyclopedic way. A relevant contribution in this field is Pierre Sylvain Régis’s Système. Régis’s contribution consists both in reconciling the new scientific discoveries with les principes de Monsieur Descartes by combining them into a scholarly manual whose aim is to stimulate the ars inveniendi and in recognizing the relevance of Arnauld’s and Nicole’s (...) L’art de penser as manual of Cartesian logic. In an article published on the «Annali della Scuola Normale Superiore di Pisa», pp. 517-55: L’«Art de penser» nella logica del «Système» di Régis) I analysed Régis’s logic in order to point out that, even if L’art de penser represents its only source, La logique of the Système has not to be considered as a mere compendium of the Port-Royal Logique, but as a revision of the latter according to a specific philosophical system, characterized by the empirical interpretation of Descartes’s philosophy. In this paper I provide a synopsis of the comparison between the logic of the Système and the Logique of Port-Royal, in order to resume in a schematic way the results of my research. (shrink)

According to Bas van Fraassen, scientific realists and anti-realists disagree about whether accepting a scientific theory involves believing that the theory is true. On van Fraassen’s own anti-realist empiricist position, accepting a theory involves believing only that the theory is correct in its claims about observable aspects of the world. However, a number of philosophers have argued that acceptance and belief cannot be distinguished and thus that the debate is either confused or trivially settled in favor of the realist. In (...) addition, another set of philosophers have argued that van Fraassen’s empiricist position appeals to an unmotivated distinction between observable and unobservable aspects of the world. This paper aims to reconstruct a van Fraassen-style empiricism about scientific acceptance that avoids these two objections – reconstructed empiricism. (shrink)

In this work, I discuss the role of Husserl’s phenomenology in Paolo Parrini’s positive philosophy. In the first section, I highlight the presence of both empiricist and constructivist elements in Parrini’s anti-foundationalist and anti-absolutist conception of knowledge. In the second section, I stress Parrini’s acknowledgement of the crucial role of phenomenology in investigating the empirical basis of knowledge, thanks to its analysis of the relationship between form and matter of cognition. In the third section, I point out some lines of (...) development of the phenomenological form of empirical realism as revealed in Parrini’s reflection, through a comparison of Husserl’s genetic phenomenology, Mary Hesse’s network model and the tradition of neutral monism.

In artificial intelligence, recent research has demonstrated the remarkable potential of Deep Convolutional Neural Networks (DCNNs), which seem to exceed state-of-the-art performance in new domains weekly, especially on the sorts of very difficult perceptual discrimination tasks that skeptics thought would remain beyond the reach of artificial intelligence. However, it has proven difficult to explain why DCNNs perform so well. In philosophy of mind, empiricists have long suggested that complex cognition is based on information derived from sensory experience, often appealing to (...) a faculty of abstraction. Rationalists have frequently complained, however, that empiricists never adequately explained how this faculty of abstraction actually works. In this paper, I tie these two questions together, to the mutual benefit of both disciplines. I argue that the architectural features that distinguish DCNNs from earlier neural networks allow them to implement a form of hierarchical processing that I call “transformational abstraction”. Transformational abstraction iteratively converts sensory-based representations of category exemplars into new formats that are increasingly tolerant to “nuisance variation” in input. Reflecting upon the way that DCNNs leverage a combination of linear and non-linear processing to efficiently accomplish this feat allows us to understand how the brain is capable of bi-directional travel between exemplars and abstractions, addressing longstanding problems in empiricist philosophy of mind. I end by considering the prospects for future research on DCNNs, arguing that rather than simply implementing 80s connectionism with more brute-force computation, transformational abstraction counts as a qualitatively distinct form of processing ripe with philosophical and psychological significance, because it is significantly better suited to depict the generic mechanism responsible for this important kind of psychological processing in the brain.

The present paper deals with the ontological status of numbers and considers Frege ́s proposal in Grundlagen upon the background of the Post-Kantian semantic turn in analytical philosophy. Through a more systematic study of his philosophical premises, it comes to unearth a first level paradox that would unset earlier still than it was exposed by Russell. It then studies an alternative path, that departin1g from Frege’s initial premises, drives to a conception of numbers as synthetic a priori in a more (...) Kantian sense. On this basis, it tentatively explores a possible derivation of basic logical rules on their behalf, suggesting a more rudimentary basis to inferential thinking, which supports reconsidering the difference between logical thinking and AI. Finally, it reflects upon the contributions of this approach to the problem of the a priori. (shrink)

Clear and distinct perception is the centrepiece of Descartes’s philosophy — it is the source of all certainty — but what does he mean by ‘clear’ and ‘distinct’? According to the prevailing approach, what it means for a perception to be clear is that its content has a certain objective property, like truth. I argue instead that clarity is at least partly a subjective, phenomenal quality whereby a content is presented as true to the perceiving subject. Clarity comes in degrees. (...) Any weak degree of clarity, available to the senses, can be merely subjective, since what it presents as true may not actually be true. But complete clarity, available to intellectual perception, has an objective dimension, since what it presents as true is always some truth, some bit of reality. Further, I argue that the other perceptual qualities that Descartes identifies — obscurity, confusion, and distinctness — are all defined in terms of clarity. Of particular note is the fact that distinctness is not a positive feature to be added to clarity: a distinct perception is just a completely clear perception. (shrink)

According to the Monist Interpretation of Descartes, there is really only one corporeal substance—the entire extended plenum. Evidence for this interpretation seems to be provided by Descartes in the Synopsis of the Meditations, where he claims that all substances are incorruptible. Finite bodies, being corruptible, would then fail to be substances. On the other hand, ‘body, taken in the general sense,’ being incorruptible, would be a corporeal substance. In this paper, I defend a Pluralist Interpretation of Descartes, according to which (...) there are many corporeal substances. In particular, I show that none of the claims in the Synopsis about incorruptibility and substance entail either that finite bodies are not substances, or that the only corporeal substance is the entire plenum.

This paper traces the ancestry of a familiar historiographical narrative, according to which early modern philosophy was marked by the development of empiricism, rationalism, and their synthesis by Immanuel Kant. It is often claimed that this narrative became standard in the nineteenth century, due to the influence of Thomas Reid, Kant and his disciples, or German Hegelians and British Idealists. The paper argues that the narrative became standard only at the turn of the twentieth century. This was not due (...) to the influence of Reid, German Hegelians, or British Idealists as they did not endorse the narrative, although Thomas Hill Green may have facilitated its uptake. The narrative is based on Kant’s historiographical sketches, as corrected and integrated by Karl Leonhard Reinhold. It was first fleshed out into full-fledged histories by two Kantians, Wilhelm Gottlieb Tennemann and Johann Gottlieb Buhle. Numerous historians, several of whom were not Kantians, spread it in the English-speaking world. They include Kuno Fischer, Friedrich Ueberweg, Richard Falckenberg, and Wilhelm Windelband. However, the wide availability of their works did not suffice to make the narrative standard because, until the 1890s, the Hegelian account was at least as popular as theirs. Among the factors that allowed the narrative to become standard are its aptness to be adopted by philosophers of the most diverse persuasions, its simplicity and suitability for teaching. (shrink)

In this chapter, I argue against empiricist positions which claim that empirical evidence can be sufficient to defeasibly justify aesthetic judgements, or judgements about the adequacy of aesthetic judgements, or sceptical judgements about someone's capacity to form adequate aesthetic judgements. First, empirical evidence provides neither inferential, nor non-inferential justification for aesthetic opinions. Second, while empirical evidence may tell us how we do respond aesthetically to artworks, it cannot tell us how we should respond to them. And, third, empirical insights into (...) the irrationality of many of our aesthetic judgements do not warrant the sceptical conclusion that we ought to refrain from forming aesthetic opinions. As a consequence of these limitations to aesthetic empiricism, we should endorse the rationalist position that aesthetic criticism is largely a matter of reasoning and, moreover, a collective undertaking.

Constructive empiricism implies that if van Fraassen does not believe that scientific theories and his positive philosophical theories, including his contextual theory of explanation, are empirically adequate, he cannot accept them, and hence he cannot use them for scientific and philosophical purposes. Moreover, his epistemic colleagues, who embrace epistemic reciprocalism, would not believe that his positive philosophical theories are empirically adequate. This epistemic disadvantage comes with practical disadvantages in a social world.

Descartes held the following view of declarative memory: to remember is to reconstruct an idea that you intellectually recognize as a reconstruction. Descartes countenanced two overarching varieties of declarative memory. To have an intellectual memory is to intellectually reconstruct a universal idea that you recognize as a reconstruction, and to have a sensory memory is to neurophysiologically reconstruct a particular idea that you recognize as a reconstruction. Sensory remembering is thus a capacity of neither ghosts nor machines, but only of (...) human beings qua mind-body unions. This interpretation unifies Descartes’s various remarks (and conspicuous silences) about remembering, from the 1628 Rules for the Direction of the Mind through the suppressed-in-1633 Treatise of Man to the 1649 Passions of the Soul. It also rebuts a prevailing thesis in the current secondary literature—that Cartesian critters can remember—while incorporating the textual evidence for that thesis—Descartes’s detailed descriptions of the corporeal mechanisms that construct sensory memories.

The present research (total N = 2,057) tested whether people’s folk conception of consciousness aligns with the notion of a “Cartesian Theater” (Dennett, 1991). More precisely, we tested the hypotheses that people believe that consciousness happens in a single, confined area (vs. multiple dispersed areas) in the human brain, and that it (partly) happens after the brain finished analyzing all available information. Further, we investigated how these beliefs arerelated to participants’ neuroscientific knowledge as well as their reliance on intuition, (...) and which rationale they use to explain their responses. Using a computer-administered drawing task, we found that participants located consciousness, but not unrelated neurological processes (Studies 1a & 1b) or unconscious thinking (Study 2) in a single, confined area in the prefrontal cortex, and that they considered most of the brain not involved in consciousness. Participants mostly relied on their intuitions when responding, and they were not affected by prior knowledge about the brain. Additionally, they considered the conscious experience of sensory stimuli to happen in a spatially more confined area than the corresponding computational analysis of these stimuli (Study 3). Furthermore, participants’ explicit beliefs about spatial and temporal localization of consciousness (i.e., consciousness happening after the computational analysis of sensory information is completed) are independent, yet positively correlated beliefs (Study 4). Using a more elaborate measure for temporal localization of conscious experience, our final study confirmed that people believe consciousness to partly happen even after information processing is done (Study 5).

The issue of time-awareness presents a critical challenge for empiricism: if temporal properties are not directly perceived, how do we become aware of them? A unique empiricist account of time-awareness suggested by Hume's comments on time in the Treatise avoids the problems characteristic of other empiricist accounts. Hume's theory, however, has some counter-intuitive consequences. The failure of empiricists to come up with a defensible theory of time-awareness lends prima facie support to a non-empiricist theory of ideas.

The syllogism and the predicate calculus cannot account for an ontological argument in Descartes' Fifth Meditation and related texts. Descartes' notion of god relies on the analytic-synthetic distinction, which Descartes had identified before Leibniz and Kant did. I describe how the syllogism and the predicate calculus cannot explain Descartes' ontological argument; then I apply the analytic-synthetic distinction to Descartes’ idea of god.

In the Principles of Philosophy, Descartes explains several observable phenomena showing that they are caused by special arrangements of unobservable microparticles. Despite these microparticles being unobservable, many passages suggest that he was very confident that these explanations were correct. In other passages, however, Descartes points out that these explanations merely hold the status of “suppositions” or “conjectures” that could be wrong. My main goal in this chapter is to clarify this apparent conflict. I argue first that for Descartes it was (...) indeed possible to have knowledge of unobservable particles and structures, and that the possibility of natural explanations being wrong should be understood as these explanations not being absolutely certain, but only morally certain. I use the debate in contemporary philosophy of science between scientific realism and antirealism as a framework to understand how Cartesian explanations work. Especifically, I argue that Cartesian explanations rely on what Ernan McMullin calls retroduction, which is a mode of inference that justifies beliefs in concrete unobservable entities and processes, based on considerations such as simplicity, coherence, etc. This kind of justification is of common use among scientific realists. Thus, another goal of this chapter is to highlight the relevance of Descartes’ ideas about explanation in the contemporary debate on scientific realism. (shrink)

Logical empiricism is commonly seen as a counter-position to scientific realism. In the present paper it is shown that there indeed existed a realist faction within the logical empiricist movement. In particular, I shall point out that at least four types of realistic arguments can be distinguished within this faction: Reichenbach’s ‘probabilistic argument,’ Feigl’s ‘pragmatic argument,’ Hempel’s ‘indispensability argument,’ and Kaila’s ‘invariantist argument.’ All these variations of arguments are intended to prevent the logical empiricist agenda from the shortcomings of (...) radical positivism, instrumentalism, and other forms of scientific antirealism. On the whole, it will be seen that logical empiricism and scientific realism are essentially compatible with each other. Especially Kaila’s invariantist approach to science (and nature) comes quite close to what nowadays is discussed under the label ‘structural realism.’ This, in turn, necessitates a fundamental reevaluation of Kaila’s role in the logical empiricist movement in particular and in twentieth-century philosophy of science in general.

This paper sets out to undermine the view that a commitment to the early modern conception of the mind as immortalized in Ryle’s metaphor of the (Cartesian) ghost in the machine and in Quine’s metaphor of the (Lockean) myth of the museum is required to articulate a defence of the sui generis character of humanistic explanations. These powerful metaphors have not only contributed to undermining the claim for methodological pluralism by caricaturizing the arguments for disunity in the sciences; they (...) have also, and more worryingly, planted red herrings that have diverted attention away from the genuine issues at stake. This paper is an exercise in removing these false clues to reveal what the claim for the autonomy of humanistic explanations really amounts to. (shrink)

It is argued that, contrary to prevailing opinion, Bas van Fraassen nowhere uses the argument from underdetermination in his argument for constructive empiricism. It is explained that van Fraassen’s use of the notion of empirical equivalence in The Scientific Image has been widely misunderstood. A reconstruction of the main arguments for constructive empiricism is offered, showing how the passages that have been taken to be part of an appeal to the argument from underdetermination should actually be interpreted.

Radical empiricism is the view that a person's experiences (sensory and introspective), or a person's observations, constitute the person's evidence. This view leads to epistemic self-defeat. There are three arguments, concerning respectively: (1) epistemic starting points; (2) epistemic norms; (3) terms of epistemic appraisal. The source of self-defeat is traced to the fact that empiricism does not count a priori intuition as evidence (where a priori intuition is not a form of belief but rather a form of seeming, (...) specifically intellectual as opposed to sensory). Moderate rationalism, by contrast, avoids self-defeat. (shrink)

One important debate between scientific realists and constructive empiricists concerns whether we observe things using instruments. This paper offers a new perspective on the debate over instruments by looking to recent discussion in philosophy of mind and cognitive science. Realists often speak of instruments as ‘extensions’ to our senses. I ask whether the realist may strengthen her view by drawing on the extended mind thesis. Proponents of the extended mind thesis claim that cognitive processes can sometimes extend beyond our brains (...) and bodies into the environment. I suggest that the extended mind thesis offers a way to make sense of realists’ talk of instruments as extensions to the senses and that it provides the realist with a new argument against the constructive empiricist view of instruments.

This paper considers George A. Reisch’s account of the role of Cold War political forces in shaping the apolitical stance that came to dominate philosophy of science in the late 1940s and 1950s. It argues that at least as early as the 1930s, Logical Empiricists such as Rudolf Carnap already held that philosophy of science could not properly have political aims, and further suggests that political forces alone cannot explain this view’s rise to dominance during the Cold War, since political (...) forces cannot explain why a philosophy of science with liberal democratic, anti-communist aims did not flourish. The paper then argues that if professionalization is understood in the right way, it might point toward an explanation of the apolitical stance of Cold War philosophy of science. (shrink)

This paper evaluates an argument according to which many anthropologists commit themselves to Cartesian dualism, when they talk about meanings. This kind of dualism, it is argued, makes it impossible for anthropologists to adequately attend to material artefacts. The argument is very original, but it is also vulnerable to a range of objections.

Having assigned experience this exclusive role in justification, empiricists then have a range of views concerning the character of experience, the semantics of our claims about unobservable entities, the nature of empirical confirmation, and the possibility of non-empirical warrant for some further class of claims, such as those accepted on the basis of linguistic or logical rules. Given the definitive principle of their position, empiricists can allow that we have knowledge independent of experience only where what is known is not (...) some objective fact about the world, but something about our way of conceptualizing or describing things. Some empiricists say we have knowledge of verbal equivalences or trivialities; some argue that any non-empirical tenets are not even properly called knowledge, but should be seen as notions accepted on pragmatic rather than properly epistemic grounds. What no empiricist will allow is substantive a priori knowledge: according to empiricism we have no pure rational insight into real necessities or the inner structure of nature, but must rely on the deliverances of our senses for all of our information about external reality. Some versions of empiricism argue against the very notion of real necessities or metaphysical structure behind the phenomena; other versions take a more agnostic approach, arguing that if there is a metaphysical structure behind the phenomena it is either out of our epistemic reach, or known only to the extent that it can be grasped through experience, rather than through rational reflection.

We sley Salmon, in his influential and detailed book, Four Decades of Scientific Explanation, argues that the pragmatic approach to scientific explanation, “construed as the claim that scientific explanation can be explicated entirely in pragmatic terms” (1989, 185) is inadequate. The specific inadequacy ascribed to a pragmatic account is that objective relevance relations cannot be incorporated into such an account. Salmon relies on the arguments given in Kitcher and Salmon (1987) to ground this objection. He also suggests that Peter Railton’s (...) concepts of the ideal explanatory text and explanatory information (Railton 1981) can provide what the pragmatic approach lacks. This suggestion is not a conclusion of course; we read it as the promotion of part of a research program aimed at forging a greater consensus on scientific explanation-an admirable goal. However, we do not see the pragmatic approach as inadequate. We will show that a synthetic account inspired by Salmon’s adaptation of Railton would be equivalent to van Fraassen’s pragmatic account in three respects: accepting or rejecting requests for explanation; the practice of giving scientific explanations; and the evaluation of the goodness of explanations. We include all three under the general rubric of explanatory “practice.” Admittedly these are not the only three features by which an account of explanation might be evaluated. Roughly, we mean to show that a synthetic account cannot do a better job of accounting for the scientific practices which are of importance to the constructive empiricist, and therefore no argument can be presented to the constructive empiricist to convince her that by her own standards the synthetic account is superior.

In this paper, I defend an empiricist account of modality that keeps a substantive account of modal commitment, but throws out the metaphysics. I suggest that if we pair a deflationary attitude toward representation with a substantive account of how scientific models are constructed and put to use, the result is an account that deflates the metaphysics of modal commitment without deflating the content of modal claims.

I examine Mach's influence on American philosophy from 1890-1910, on Carus, James, Peirce, the American Realists and J.B. Stallo. I also consider the question of whether Mach was a pragmatist in the sense of Peirce and James. I conclude that early pragmatism was a method-centric theory whereas Mach's empiricism prized agreement with experience and downplayed the significance of inductive-scientific methods in general as a guide to discovery.

Since Descartes, the nature of doubt has played a central role in the development of metaphysics both positively and negatively. Despite this fact, there has been very little discussion centering round the specific nature of doubt which led, for example, to the Cartesian discovery of the cogito. Certainly, the role of doubt has been well recognized: through doubt Descartes arrives at his indubitable first principle. But what can it mean to doubt the existence of the sensible world? This would (...) seem to rest upon the assumption that we have clear and distinct knowledge of the precise nature of what it means to exist and indeed of what it means to be. As it stands, Descartes’ initiates his Meditations upon certain definite assumptions that demand more thorough interrogation. In this paper and presentation, I examine the possible assumptions inherent in the Cartesian method of doubt within the first and second meditation and the manner in which this leads to the discovery of the cogito. I consider a number of essential questions in light of this: What presuppositions lie at bottom to Cartesian doubt? What is the precise nature of metaphysical doubt? What can it mean to doubt the existence of the sensible world? (shrink)

In this paper we suggest a revisionist perspective on two significant figures in early modern life science and philosophy: William Harvey and John Locke. Harvey, the discoverer of the circulation of the blood, is often named as one of the rare representatives of the ‘life sciences’ who was a major figure in the Scientific Revolution. While this status itself is problematic, we would like to call attention to a different kind of problem: Harvey dislikes abstraction and controlled experiments (aside from (...) the ligature experiment in De Motu Cordis), tends to dismiss the value of instruments such as the microscope, and emphasizes instead the privileged status of ‘observed experience’. To use a contemporary term, Harvey appears to rely on, and chiefly value, ‘tacit knowledge’. Secondly, Locke’s project is often explained with reference to the image he uses in the Epistle to the Reader of his Essay, that he was an “underlabourer” of the sciences. In fact, despite the significant medical phase of his career, Locke’s ‘empiricism’ turns out to be above all a practical (i.e. ‘moral’) project, which focuses on the delimitation of our powers in order to achieve happiness, and rejects the possibility of naturalizing knowledge. When combined, these two cases suggest a different view of some canonical moments in early modern natural philosophy. (shrink)

This paper examines the settlement movement (a social reform movement during the Progressive Era, roughly 1890–1920) in order to illustrate what pragmatism is and is not. In 1906, Mary Kingsbury Simkhovitch proposed an analysis of settlement house methods. Because of her emphasis on interpretation and action, and because of the nature of the settlement movement as a social reform effort with vitally important consequences for everyone involved, it might be thought that her analysis would be pragmatist in character. This paper (...) shows that her analysis is empiricist, not pragmatist, and offers an alternative pragmatist sketch of settlement house methodology. (shrink)

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)

This paper deals with the philosophical problems concerned with research in the field of artificial intelligence (AI), in particular with problems arising out of claims that AI exhibits ‘consciousness’, ‘thinking’ and other ‘inner’ processes and that they simulate human intelligence and cognitive processes in general. The argument is to show how Cartesian mind is non-mechanical. Descartes’ concept of ‘I think’ presupposes subjective experience, because it is ‘I’ who experiences the world. Likewise, Descartes’ notion of ‘I’ negates the notion of (...) computationality of the mind. The essence of mind is thought and the acts of thoughts are identified with the acts of consciousness. Therefore, it follows that cognitive acts are conscious acts, but not computational acts. Thus, for Descartes, one of the most important aspects of cognitive states and processes is their phenomenality, because our judgments, understanding, etc. can be defined and explained only in relation to consciousness and not in relation to computationality. We can only find computationality in machines and not in the mind, which wills, understands and judges. (shrink)

One of the most common criticisms one hears of the idea of granting a legitimate role for social values in theory choice in science is that it just doesn’t make sense to regard social preferences as relevant to the truth or to the way things are. “What is at issue,” wrote Susan Haack, is “whether it is possible to derive an ‘is’ from an ‘ought.’ ” One can see that this is not possible, she concludes, “as soon as one expresses (...) it plainly: that propositions about what states of affairs are desirable or deplorable could be evidence that things are, or are not, so” (Haack 1993a, 35, emphasis in original). The purpose of this chapter is not to determine whether this widespread view is correct, but rather to show that even if we grant it (which I do), we may still consistently believe that social values have a legitimate role in theory choice in science. I will defend this conclusion by outlining a view about social values and theory choice that is available to a Constructive Empiricist anti-realist, but not to a realist. (shrink)

Recent work on skin-brain thesis suggests the possibility of empirical evidence that empiricism is false. It implies that early animals need no traditional sensory receptors to be engaged in cognitive activity. The neural structure required to coordinate extensive sheets of contractile tissue for motility provides the starting point for a new multicellular organized form of sensing. Moving a body by muscle contraction provides the basis for a multicellular organization that is sensitive to external surface structure at the scale of (...) the animal body. In other words, the nervous system first evolved for action, not for receiving sensory input. Thus, sensory input is not required for minimal cognition; only action is. The whole body of an organism, in particular its highly specific animal sensorimotor organization, reflects the bodily and environmental spatiotemporal structure. The skin-brain thesis suggests that, in contrast to empiricist claims that cognition is constituted by sensory systems, cognition may be also constituted by action-oriented feedback mechanisms. Instead of positing the reflex arc as the elementary building block of nervous systems, it proposes that endogenous motor activity is crucial for cognitive processes. In the paper, I discuss the issue whether the skin-brain thesis and its supporting evidence can be really used to overthrow the main tenet of empiricism empirically, by pointing out to cognizing agents that fail to have any sensory apparatus.
