This volume brings together for the first time a significant number of Reid's manuscript papers on natural history, physiology and materialist metaphysics. An important contribution not only to Reid studies but also to our understanding of eighteenth-century science and its context.

In lieu of an abstract, here is a brief excerpt of the content:Thomas Reid on MemoryRené van Woudenbergthis paper is a discussion of Thomas Reid’s views on memory as an “avenue of knowledge.” Part 1 deals with various remarks Reid makes concerning memory, knowledge, and belief which he holds to be “obvious and certain.” Part contains a more detailed discussion of Reid’s thesis that “memory is unaccountable.” Part 3 inquires how Reid’s critique of the Way (...) of Ideas fits with his own views on memory.Reid’s dealings with memory are part of his broader inquiries into the intellectual faculties of the human mind. In the Essays on the Intellectual Powers of Man Reid discusses not only memory, but other avenues of knowledge as well, such as perception and reasoning. In these essays Reid is doing straight epistemology. This is not to deny that Reid addresses other topics as well. In the essay on memory, for instance, Reid criticizes John Locke’s account of personal identity. But even then his discussion focusses on epistemological matters; one of his conclusions, for example, is that Locke confounded personal identity with the evidence we have of our personal identity, a thesis, Reid points out, that is bristled with absurd consequences. Although, then, Reid’s views on memory are related with his views on personal identity, I will abstain from a discussion of the latter. His epistemology of memory, I think, warrants attention in its own right.11. memory, knowledge, and beliefI.IIn Essay III of his Essays on the Intellectual Powers of Man [1784],2 entitled “Of Memory,” Reid writes: [End Page 117]It is by memory that we have an immediate knowledge of things past. The senses give us information of things only as they exist in the present moment.(EIP 339)Memory, says Reid, gives us knowledge of things past, whereas sense perception gives us knowledge of things present. Reid takes it to be “obvious and certain” (as the title of the first chapter of Essay III indicates) that “The object of memory, or thing remembered, must be something that is past; as the object of perception... must be something which is present. What now is, cannot be an object of memory; neither can that which is past and gone be an object of perception” (EIP 340).These remarks may, however, occasion some doubts. One way of explaining Reid’s remark that the object of memory is something that is past, is that whenever someone, S, remembers something, viz., that p, p will be a proposition about something that is past.3 This explanation gives the right result for such propositions as there was snowfall in late August, and she once visited Finland4 But, as Norman Malcolm has observed, it does not always give the right results.5 For, he says, there are cases of S remembering that p, where p is not a proposition about the past. Let p be his telephone number is 2 79-289-59 75, or his car is in the garage. What is remembered, in these cases, is a proposition about something that is not past, but present (or: about what is presently the case). It is, so it seems at least, possible for S to remember the present.It even seems possible for S “to remember the future” (something Aristotle deemed impossible).6 S can remember, for instance, that the game starts at 8:00 P.M., or that there will be elections next year.No doubt some will find these suggestions preposterous. Still, we say such things as “I remember my telephone number” and “I remember the game starts at 8:00 P.M.” Someone who balks at the suggestion that we can remember present and even future things, therefore, has to find a way of dealing with these quite common modes of saying. One way would be to argue that these manners of saying are incorrect, another that they are elliptical. Since the first thesis is unconvincing (it is, after all, correct, i.e., correct English to use the expressions under consideration), we are left with the second, viz., that these modes of saying are elliptical.

This is Thomas Reid's greatest work. It covers far more philosophical ground than the earlier, more popular Inquiry. The Intellectual Powers and its companion volume, Essays on the Active Powers of Man, constitute the fullest, most original presentation of the philosophy of Common Sense. In the process, Reid provides acutely critical discussions of an impressive array of thinkers but especially of David Hume. In Reid's eyes, Hume had driven a deep tendency in modern philosophy to its ultimate (...) conclusions by creating a phantom-world of so-called 'ideas' that sprang from objects of observation; the self was a conglomeration of perceived ideas; and the will as the source of action was nothing but the balance of passionate impulses. -/- Reid's Common Sense philosophy answers these problems by suggesting that sceptics, such as Hume, unavoidably affirm what they purport to deny, namely the existence of a stable external world, of other minds, of the continuity of their own minds, and of their own and other people's ability to ascribe and accept responsibility for actions. We can understand all of this by proper empirical observation and philosophical analysis of the activity of the mind. Reid's major positive contribution to philosophy is a detailed account of the various innate powers of the mind. While particularly influential in the first half of the nineteenth century, Reid's work has retained a significant role in philosophy, not least in recent years.

This volume -- a companion to Thomas Reid: Selected Philosophical Writings (2012) -- makes available material from Thomas Reid's autograph manuscripts and student notes of his lectures. It includes an introductory essay by Nicholas Wolterstorff.

The paper states a hypothesis concerning Thomas Reid's moderation in his reply to skepticism. It is initially argued that commonsense beliefs, though due to reliable faculties, are doubtful, fallible, and correctable. They are not completely immune to skeptical attack. It is further argued that Reid intends to reply only to one form of skepticism, the partial one – the skepticism of authors who accept at least one mental faculty as a reliable source of knowledge. Reid does not (...) intend to argue with the skeptic who equally denies his assent to the reliability of all faculties – that is, the radical skeptic. This radical form of skepticism is harmless to practical life and philosophy and, for that reason, is not a threat. Finally, the hypothesis advanced is discussed considering other interpretations of Reid’s reply to skepticism. (shrink)

The paper aims to present two distinct ways of defending John Locke’s theory of personal identity from Thomas Reid’s objection. First, it will be argued that this objection is not effective since it starts from a misunderstanding of Locke’s theory. The identity of a person is not preserved by the psychological continuity of consciousness, as Reid understood it, but by its ontological continuity: the existence of the same consciousness preserves the personal identity. Secondly, it will be argued that (...) it is possible to reply to that objection in the light of the observation that the personal identity is preserved by the identity of the man: person and man are connected by means of the notion of body.

The two great philosophical figures at the culminating point of the Enlightenment are Thomas Reid in Scotland and Immanuel Kant in Germany. Reid was by far the most influential across Europe and the United States well into the nineteenth century. Since that time his fame and influence have been eclipsed by his German contemporary. This important book by one of today's leading philosophers of knowledge and religion will do much to reestablish the significance of Reid for philosophy (...) today. Nicholas Wolterstorff has produced the first systematic account of Reid's epistemology. Relating Reid's philosophy to present-day epistemological discussions the author demonstrates how they are at once remarkably timely, relevant, and provocative. No other book both uncovers the deep pattern of Reid's thought and relates it to contemporary philosophical debate. This book should be read by historians of philosophy as well as all philosophers concerned with epistemology and the philosophy of mind. (shrink)

With a new reading of Thomas Reid on primary and secondary qualities, Christopher A. Shrock illuminates the Common Sense theory of perception. Shrock follow's Reid's lead in defending common sense philosophy against the problem of secondary qualities, which claims that our perceptions are only experiences in our brains, not of the world.

Nichols offers the first comprehensive interpretation of the eighteenth-century Scottish philosopher Thomas Reid's theory of perception - by far the most important feature of his philosophical system. Nichols's consummate knowledge of Reid's texts, lively examples, and plainspoken style make this book especially readable. It will be the definitive analysis for a long time to come.

Direct Realism is the view that human perception takes physical entities and their mind-independent properties as immediate objects. Although this thesis is supported by common sense, many argue that it can be dismissed on philosophical or quasi-scientific grounds. This essay attempts to defend Direct Realism against one such argument, which I call the “Problem of Secondary Qualities,” using the ideas of Scottish Common Sense philosopher Thomas Reid. The first chapter of this work offers a detailed introduction to the Problem (...) of Secondary Qualities. The Problem of Secondary Qualities arises from the claim that science has shown that physical objects do not possess secondary qualities. This is a problem for Direct Realism because secondary qualities are certainly possessed by at least some perceivable objects. As I present it, the Problem rests on three commitments: that an analysis of secondary quality perceptions should extend to perception in general, that we perceive secondary qualities, and that physical objects do not possess secondary qualities without our perceptions of them. I conclude that Direct Realism requires an account of secondary qualities on which secondary qualities are perceiver-independent but identifiable with other causally relevant properties. In Chapter Two, I introduce Thomas Reid’s doctrine of primary and secondary qualities, in the context of his theory of perception, as a viable response to the Problem of Secondary Qualities. On Reid’s view, secondary qualities are both perceiver-independent and identical to scientific properties, and Reid offers many useful conceptual resources for responding to objections. Most important are Reid’s claims that sensation or sense experience is casually related to, but not essential for, perception and that our perceptions of secondary qualities give us very little knowledge concerning their natures. The final chapter shows how the Reidian theory holds up against four key objections to accounts of secondary qualities on which they may be identified with perceiver-independent, scientific properties. In most cases, the Reidian approach finds solutions without compromising our intuitions or received opinions. (shrink)

Thomas Reid thought of himself as a critic of the representative theory of perception, of what he called the ‘theory of ideas’ or ‘the ideal theory’.2 He had no kind words for that theory: “The theory of ideas, like the Trojan horse, had a specious appearance both of innocence and beauty; but if those philosophers had known that it carried in its belly death and destruction to all science and common sense, they would not have broken down their walls (...) to give it admittance.”3 Many have supposed that his opposition to the representative theory was grounded in his direct realism.4 A direct realist theory of perception holds that perception of external objects is not mediated by any mental entity whose intrinsic character licenses a move from the mental entity to the external object presented in perception. Reid himself, in an oration of 1759, delivered at graduation ceremonies over which he presided as regent and professor of philosophy at King’s College in Aberdeen, said that he did not “understand what need there is of an intermediate object for thought about something to be possible.”5 Hence, if Reid was not a direct realist, philosophers and historians would have to ask whether and to what degree Reid was what he thought himself to be. (shrink)

Thomas Reid's distinction between original and acquired perception is not merely metaphysical; it has psychological and phenomenological stories to tell. Psychologically, acquired perception provides increased sensitivity to features in the environment. Phenomenologically, Reid's theory resists the notion that original perception is exhaustive of perceptual experience. James Van Cleve has argued that most cases of acquired perception do not count as perception and so do not pose a threat to Reid's direct realism. I argue that acquired perception is (...) genuine perception and as direct as original perception. Perception is grounded in a productive and developing relationship between the mind and world. (shrink)

Thomas Reid's philosophy of mind, epistemology, and philosophy of language all rely on his account of signs and signification. On Reid's view, some entities play a role of indicating other entities to our minds. In some cases, our sensitivity to this indication is learned through experience, whereas in others, the sensitivity is built in to our natural constitutions. Unlike representation, which was presumed to depend on resemblances and necessary connections, signification is the sort of relationship that can occur (...) without any intrinsic ties between the sign and the thing signified. Of particular interest is the priority Reid gives to natural signs. Reid deploys his robust account of natural signs in a way that allows him to sidestep some skeptical worries common in the early modern period, as well as in grounding “artificial” human languages like English or Cantonese on a more basic human capacity for communication, that is, itself, the result of our sensitivity to natural signs of other people's minds.

Thomas Reid offers a powerful challenge to Hume and his skeptical system. In “Thomas Reid on Epistemic Principles,” William Alston gives an explanation of that challenge and concludes in favor of a Reidian-inspired thesis. I argue, however, that Alston’s thesis is a diluted version of Reid’s radical position, one that Reid’s principles cannot accommodate. Thus, I conclude that, because Alston’s position is not available, we are left with Reid’s radical thesis, with which we are rightly (...) uncomfortable. (shrink)

The notion of “conception” plays a central role in Thomas Reid’s theory of perceptual knowledge, although “conception” might be studied for itself as a source of knowledge. In this study, we attempt to expose systematically the several contexts where Reid deals with the source of knowledge and the kind of mental operation called “conception”. The purpose is to understand a specific aspect of the deliverances of “conception” in Reid’s theory of perception, namely, a direct relationship, not mediated (...) by ideas, between knowing subject and external world. To understand the operation of conceiving, which is intrinsic to and constitutive of perception, is an efficient way to comprehend the nature and content of perceptual knowledge. At this step, reflections on the relationship between mind and external world, that is, mind and material world, have to be made. (shrink)

The paper covers the discussion of three aspects of Thomas Reid’s political thought. Initially, it presents and discusses Reid’s understanding of Politics. Secondly, it is argued that, unlike the first principles of other branches of knowledge, such as Mathematics, Philosophy of Mind and Morals, the first principles of Politics are not the first principles of common sense. Politics is founded on a form of empirical knowledge that cannot be identified with common sense, with the judgments and beliefs due (...) to the original constitution of mind that are shared by most humans. Finally, it is argued, from a parallel with the philosophy of nature, that common sense has only a methodological role in Politics. (shrink)

Philosophical orthodoxy holds that Thomas Reid is an externalist concerning epistemic justification, characterizing Reid as holding the key to an externalist response to internalism. These externalist accounts of Reid, however, have neglected his work on prejudice, a heretofore unexamined aspect of his epistemology. Reid’s work on prejudice reveals that he is far from an externalist. Despite the views Reid may have inspired, he exemplifies internalism in opting for an accessibility account of justification. For Reid, (...) there are two normative statuses that a belief might satisfy, being blameless and having a just ground. Through reflection, a rational agent is capable of satisfying both of these statuses, making Reid an accessibility internalist about epistemic justification. (shrink)

A brief introduction to Thomas Reid's philosophy on language.

This paper reconstructs Reid 's responses to regress arguments against the possibility of free will, highlighting the role played by long-term decisions in the explanation of paradigmatic free actions on Reid 's account. In addition to reconstructing Reid 's response to the two versions of the regress argument that he explicitly discusses, I also construct a Reidian response to Galen Strawson's contemporary version of the regress argument. The depth of Reid 's position is most apparent in (...) the resources it provides for responding to this sophisticated articulation of a traditional argument against freedom of the will. (shrink)

Seventeen years before Kant published The Critique of Pure Reason, there appeared another work designed to undercut Hume’s skepticism and the principles upon which that skepticism was based—Thomas Reid’s Inquiry into the Human Mind on the Principles of Common Sense. In this ambitious work, Reid hoped to show, against Hume, that there need be no quarrel between common sense and philosophical inquiry. “Philosophy,” proclaimed Reid, “has no other roots but the principles of Common Sense; it grows out (...) of them, and draws its nourishment from them.” Reid’s self-imposed task was thus two-fold—to expose the errors in philosophical method which had inexorably culminated in Hume’s phenomenalistic atomism, and correlatively to provide a more adequate metaphysical scheme which could avoid the pitfalls of skepticism while doing justice to our ordinary beliefs about the world.

This paper presents a rationale for doing philosophy with children. It suggests a rationale that differs from more usual arguments supporting philosophy with children—for such reasons as that it will enhance problem solving-skills or will help pupils' thinking to be more logical. These worthy objectives are not denied but only considered somewhat subordinate to the rationale proposed. This is presented in three steps. In the first step the issue of whether philosophy should be done with children is considered in the (...) context of claims that children may be too young to do philosophy or too inexperienced in the ways of academic discipline to be able to discern proper philosophy. These objections are weighty enough, especially in view of general teacher reluctance to engage with philosophy itself in any form. In the second part, I invoke the common sense philosophy of Thomas Reid as a method of philosophy particularly significant for, and appropriate to, philosophy for children. Finally, I show how these aspects arising out of my understanding of Reid's philosophy can help resolve at least some of the misgivings people have about doing philosophy with children. It is hoped that these discussions will illuminate the question of how it may be appropriate for children to do philosophy in classrooms today. (shrink)

In a brief but remarkable section of the Inquiry into the Human Mind, Thomas Reid argued that the visual field is governed by principles other than the familiar theorems of Euclid—theorems we would nowadays classify as Riemannian. On the strength of this section, he has been credited by Norman Daniels, R. B. Angell, and others with discovering non-Euclidean geometry over half a century before the mathematicians—sixty years before Lobachevsky and ninety years before Riemann. I believe that Reid does (...) indeed have a fair claim to have discovered a non-Euclidean geometry. However, the real basis of Reid’s geometry of visibles is subtle and easy to misidentify. My main aim in what follows is to make clear what the real basis is, separating it from several fallacious or irrelevant considerations on which Reid may seem to be relying. A secondary aim is to air the worry that Reid’s case for his geometry can succeed only at the cost of compromising the achievement for which Reid is best known—his direct realist theory of perception.

: Some critics find that Thomas Reid thinks the mind especially problematic, "hid in impenetrable darkness". I disagree. Reid does not hold that mind, more than body, resists explanation by the new science. The physical sciences have made great progress because they were transformed by the Newtonian revolution, and the key transformation was to stop looking for causes. Reid's harsh words are a call for methodological reform, consonant with his lifelong pursuit of a science of mind and (...) also with his frequent (though overlooked) optimism about such a science.

Background: Locke's Conception of Freedom For how can we think any one freer than to have the power to do what we will. — John Locke n his chapter on power ...

Little attention has been paid to the fact that Thomas Reid's epistemology applies to ‘political reasoning’ as well as to various operations of the mind. Reid was interested in identifying the ‘first principles’ of political science as he did with other domains of human knowledge. This raises the question of the extent to which the study of human action falls within the competence of ‘common sense’. Our aim is to reconstruct and assess Reid's epistemology of the sciences (...) of social action and to determine how it connects with the fundamental tenets of his general epistemology. In the first part, we portray Reid as a methodological individualist and focus on the status of the first principles of political reasoning. The second part examines Reid's views on the explanatory power of the principles of human action. Finally, we draw a parallel between Reid's epistemology and the methodology of Weberian sociology.

The paper discusses Thomas Reid's objection to David Hume's theory of personal identity. The hypothesis states that this criticism is not effective because it is based on a misunderstanding of Hume’s theory, namely, that Hume would have admitted a negative ontological thesis - the inexistence of a mind beyond perceptions - and a positive ontological thesis - a mind reduced to a bundle of perceptions. After explaining in what measures Reid’s objection is based upon this misunderstanding, the paper (...) shows why Hume does not accept those theses,. (shrink)

The paper presents and discusses how Thomas Reid's philosophy of common sense replies to the skepticism about the epistemic reliability of the faculties of mind. The hypothesis presented establishes that Reid’s reply has three arguments. First, Reid shows why it is impossible to prove the reliability of the faculties of mind and why philosophers may begin their investigations by accepting the truth of the beliefs due to these faculties. Secondly, Reid shows that it is inconsistent to (...) choose one of these faculties as the only source of true beliefs. This is arbitrary. Those authors, who choose, for example, consciousness as the only source of reliable knowledge, only reinforce the claim that all faculties of mind are equally reliable. Thirdly, if the faculties of the mind operate properly, that is, when our mind is not affected by any disorder or disease, there is no good reason to call them into question and to doubt the truth of their beliefs.

Best known as a moralist and one of the founders of the Scottish Common Sense school of philosophy, Thomas Reid was also an influential scientific thinker. Here his work on the life sciences is studied in detail, bringing together unpublished transcripts of his most important papers on natural history, physiology, and materialist metaphysics. Part I provides the first published account of Reid's reflections on the highly controversial theories surrounding muscular motion and the reproduction of plants and animals and (...) relates them to the broader Enlightenment debates on these issues. It also contains the first systematic reconstruction of Reid's opposition to materialism and views his polemics against the noted Dissenter Joseph Priestley in terms of their differing interpretations of the Newtonian legacy, their conflicting philosophical assumptions, and the cultural politics of Common Sense philosophy in the 1770s. Part II reproduces a selection of Reid's most significant papers on the life sciences, including his Glasgow Literary Society discourses on muscular motion and on Priestley's materialism, as well as other manuscripts that document the development of his scientific ideas.

Thomas Reid’s epistemological ambitions are decisively at the center of his work. However, if we take such ambitions to be the whole story, we are apt to overlook the theory of mind that Reid develops and deploys against the theory of ideas. Reid’s philosophy of mind is sophisticated and strikingly contemporary, and has, until recently, been lost in the shadow of his other philosophical accomplishments. Here I survey some aspects of Reid’s theory of mind that I (...) find most interesting. I examine whether Reid is a mysterian about the mind, whether Reid has a direct realist theory of perception, and whether Reid has a higher-order, or “inner-sense,” view of consciousness. Along the way I will mention portions of the secondary literature that examine these aspects and point out whether and to what degree I part ways with the interpretations present in the literature.

: Thomas Reid uses the notion of exertion in various ways that have not been distinguished in the secondary literature. Sometimes he uses it to refer to the exercise of a capacity or power, sometimes to the turning on or activitating of a capacity or power, and still other times to the attempt to activate a capacity or power. Getting clear on Reid's different uses of the term 'exertion' is essential to understanding his account of the sequence of (...) events in human action. It is also helpful in defending Reid against the objection that his account of action is subject to an infinite regress. (shrink)

Reid was a Newtonian and a Theist, but did he found his Theism on Newton’s physics? In opposition to commonplace assumptions about the role of Theism in Reid’s philosophy, my answer is no. Reid prefers to found his Theism on a priori reasons, rather than on physics. Reid’s understanding of physics as an empirical science stops it from contributing in any clear and efficient way to issues of natural theology. In addition, Reid is highly sceptical (...) of our ability to discover the efficient and final causes of natural phenomena, knowledge of which is essential for natural theology. To bring out Reid’s differences with classical Newtonian Theists Richard Bentley and William Whiston, I examine their use of the law and force of general gravitation, and reconstruct what would be Reidian objections.Keywords: Thomas Reid; William Whiston; Richard Bentley; Physics; Theism; Isaac Newton.

The paper argues that it is a mistake to interpret Thomas Reid as holding a libertarian notion of freedom, and to make use of Reid to argue in support of a libertarian position. More precisely, this paper shows that Reid’s theory of agent-causation may not be what these philosophers take it to be, once such crucial notions as agent-causation and active power in Reid’s theory of free agency have been fully explicated. Reid is more committed (...) to accepting the view of freedom as rational self-control over the determination of the will than a contracausal view of freedom. (shrink)

Thomas Reid (1710–1796) presented a two-dimensional geometry of the visual field in his Inquiry into the human mind (1764), whose axioms are different from those of Euclidean plane geometry. Reid’s ‘geometry of visibles’ is the same as the geometry of the surface of the sphere, described without reference to points and lines outside the surface itself. Interpreters of Reid seem to be divided in evaluating the significance of his geometry of visibles in the history of the discovery (...) of non-Euclidean geometries. The question will be reexamined with particular attention given to his unpublished manuscripts. These include comments on Saccheri’s work and Reid’s repeated attempts to derive Euclid’s parallel postulate from the axioms of incidence. (shrink)

Thomas Reid uses the notion of exertion in various ways that have not been distinguished in the secondary literature. Sometimes he uses it to refer to the exercise of a capacity or power, sometimes to the turning on or activitating of a capacity or power, and still other times to the attempt to activate a capacity or power. Getting clear on Reid's different uses of the term 'exertion' is essential to understanding his account of the sequence of events (...) in human action. It is also helpful in defending Reid against the objection that his account of action is subject to an infinite regress. (shrink)

Independently of any eighteenth century work on the geometry of parallels, Thomas Reid discovered the non-euclidean "geometry of visibles" in 1764. Reid's construction uses an idealized eye, incapable of making distance discriminations, to specify operationally a two dimensional visible space and a set of objects, the visibles. Reid offers sample theorems for his doubly elliptical geometry and proposes a natural model, the surface of the sphere. His construction draws on eighteenth century theory of vision for some (...) of its technical features and is motivated by Reid's desire to defend realism against Berkeley's idealist treatment of visual space.

Thomas Reid is known as the founder of the common-sense school of philosophy, also known as the Scottish school. This group had considerable influence in Great Britain and in North America during the 19th century. Common sense is regarded as self-evident knowledge, the means by which we know the objects of the external world. These objects are known to us in their true sense and not as copies or ideas. This is the theory of natural realism and is the (...) point of difference with the theories of John Locke. In this collection of papers, many first delivered at a conference at the University of Glasgow held to celebrate the bicentenary of Reidâ??s death, the eminent contributors open a number and variety of doors into Reid and remind us that he remains a relevant force today.

Thomas Reid’s philosophy is a philosophy of mind—a Pneumatology in the idiom of 18th century Scotland. His overarching philosophical project is to construct an account of the nature and operations of the human mind, focusing on the two-way correspondence, in perception and action, between the thinking principle within and the material world without. Like his contemporaries, Reid’s treatment of these topics aimed to incorporate the lessons of the scientific revolution. What sets Reid’s philosophy of mind apart is (...) his commitment to a set of intuitive contingent truths he called the principles of common sense. This difference, as this chapter will show, enables Reid to construct an account of mind that resists the temptation to which so many philosophers in his day and ours succumb, i.e., the temptation, in his words, to materialize minds or spiritualize bodies.
