The concept of empiricism evokes both a historical tradition and a set of philosophical theses. The theses are usually understood to have been developed by Locke, Berkeley, and Hume. But these figures did not use the term “empiricism,” and they did not see themselves as united by a shared epistemology into one school of thought. My dissertation analyzes the debate that elevated the concept of empiricism (and of an empiricist tradition) to prominence in English-language philosophy. -/- In the 1870s and (...) ’80s a lively debate about psychology emerged. Neo-Kantian idealists criticized the very idea that the mind can be studied scientifically. A group of philosopher-psychologists responded, often in Mind. They were among the first to call themselves “empiricists,” arguing that psychology could provide a scientific basis for philosophical progress. Idealists held that empirical psychology depended on premises developed by Locke, Berkeley, and Hume. These premises were allegedly absurd because they rendered ideas of extension, as well as other ideas crucial to natural science, unreal. Those who wanted to advance psychology towards becoming a legitimate science were forced to engage these philosophical attacks, while at the same time to develop empirical theories that could successfully explain some characteristics of experience. I show how James’s theory of space perception accomplished both tasks. -/- In developing this theory, James found he had to reject the Lockean notion that reality is associated with passively-registered sensations. James also abandoned Berkeley and Hume’s claim that ideas are ultimately derived from atomic sensations. Instead, James presented experimental evidence that sensation is a continuous stream. The mind must actively parse this stream if it is to gain a coherent representation of its environment. I argue that James’s stream-of-thought thesis served as a presupposition of his entire psychology. The thesis showed how the labor of investigating the mind could be divided between philosophers and scientists, and in a manner sensitive to the concerns of both. The stream thesis also provided a scientific basis for a new philosophical empiricism that, I argue, has a hidden legacy in the history of analytic philosophy. (shrink)

George Berkeley, Bishop of Cloyne, was one of the great philosophers of the early modern period. He was a brilliant critic of his predecessors, particularly Descartes, Malebranche, and Locke. He was a talented metaphysician famous for defending idealism, that is, the view that reality consists exclusively of minds and their ideas. Berkeley's system, while it strikes many as counter intuitive, is strong and flexible enough to counter most objections. His most studied works, the Treatise Concerning the Principles of Human Knowledge (...) Principles, for short) and Three Dialogues between Hylas and Philonous Dialogues), are beautifully written and dense with the sort of arguments that delight contemporary philosophers. He was also a wide ranging thinker with interests in religion (which were fundamental to his philosophical motivations), the psychology of vision, mathematics, physics, morals, economics, and medicine. Although many of Berkeley's first readers greeted him with incomprehension, he influenced both Hume and Kant, and is much read (if little followed) in our own day. (shrink)

In his 'Inquiry', Reid claims, against Berkeley, that there is a science of the perspectival shapes of objects ('visible figures'): they are geometrically equivalent to shapes projected onto the surfaces of spheres. This claim should be understood as asserting that for every theorem regarding visible figures there is a corresponding theorem regarding spherical projections; the proof of the theorem regarding spherical projections can be used to construct a proof of the theorem regarding visible figures, and vice versa. I reconstruct Reid's (...) argument for this claim, and expose its mathematical underpinnings: it is successful, and depends on no empirical assumptions to which he was not entitled about the workings of the human eye. I also argue that, although Reid may or may not have been aware of it, the geometry of spherical projections is not the only geometry of visible figure. (shrink)

In 1739 Hume bequeathed a bold view of the self to the philosophical community that would prove highly influential, but equally controversial. His bundle theory of the self elicited substantial opposition soon after its appearance in the Treatise of Human Nature. Yet Hume makes it clear to his readers that his views on the self rest on respectable foundations: namely, the views of the highly regarded Irish philosopher, George Berkeley. As the author of the Treatise sees it, his account of (...) the self draws on Berkeley’s conception of language, especially his views on singular terms. But Hume, as impressed as he is with Berkeley’s account of language, deems it necessary to defend this view against possible criticism. In the process Hume modifies Berkeley’s views. My paper is a critical investigation of Hume’s defense of Berkeley on language and an attempt to highlight the extent to which Hume departs from the views of his Irish colleague. -/- . (shrink)

The early modern period (roughly, 1600–1800 ce) in Europe brought tremendous changes in intellectual, political, and cultural life. It was a period in which philosophical debates were inevitably bound up with questions about the nature and sources of religious truth. A chronological examination of some of the period’s major thinkers highlights two issues that were central to the development of philosophy of religion in the period. The first concerns the relations between God, the soul, and the body; the other concerns (...) the relationship between human reason and divine revelation. (shrink)

Editors' preface to the book symposium on Michael Ayers' Knowing and Seeing. Groundwork for a New Empiricism (OUP 2019).

This paper analyzes a conference panel discussion entitled "Identity in Crisis: The Issue of Agency in Social Constructionism and Postmodernism" in order to identify some limits to intellectual discussion. The panel participants made a deliberate attempt to engage in a self-reflexive language game about the language game of intellectual discussion in the conference format. This attempt revealed the highly sedimented nature of discursive practice in the conference setting, at least, and perhaps more generally. This analysis of the extent to which (...) sedimented practices limit the exercise of agency highlights academic practices which typically are hidden or considered too obvious to merit attention.

Sounds are audible, and sound sources are audible. What is the audible relation between audible sounds and audible sources? Common talk and philosophy suggest three candidates. The first is that sounds audibly are properties instantiated by their sources. I argue that sounds are audible individuals and thus are not audibly instantiated by audible sources. The second is that sounds audibly are effects of their sources. I argue that auditory experience presents no compelling evidence that sounds audibly are causally related to (...) audible sources. The third is that sounds audibly are related mereologically to their sources. I present and offer a defence of this third candidate. (shrink)

Two notable thought experiments are discussed in this article: Reid's thought experiment about whether a being supplied with tactile sensations alone could acquire the conception of extension and Strawson's thought experiment about whether a being supplied with auditory sensations alone could acquire the conception of mind-independent objects. The experiments are considered alongside Campbell's argument that only on the so-called relational view of experience is it possible for experiences to make available to their subjects the concept of mind-independent objects. I consider (...) how the three issues ought to be construed as raising questions about woulds, coulds, or shoulds. (shrink)

Two theses appear to be central to Reid’s view of the visual field. By sight, we do not originally perceive depth or linear distance from the eye. By sight, we originally perceive the position that points on the surface of objects have with regard to the centre of the eye. In different terms, by sight, we originally perceive the compass direction and degree of elevation of points on the surface of objects with reference to the centre of the eye. I (...) consider various problems about distance perception and perception of position with regard to the centre of the eye raised by Reid’s texts. These questions are relevant to Reid’s description of the geometry of visibles as the “intrinsic” geometry of the surface of the sphere. (shrink)

How does the mind attribute external causes to internal sensory experiences? Adam Smith addresses this question in his little known essay ‘Of the External Senses.’ I closely examine Smith's various formulations of this problem and then argue for an interpretation of his solution: that inborn perceptual mechanisms automatically generate external attributions of internal experiences. I conclude by speculating that these mechanisms are best understood to operate by simulating tactile environments.
