This book bears witness to the current reawakening of interest in Reid's philosophy. It first examines Reid's negative attack on the Way of Ideas, and finds him to be a devastating critic of his predecessors.

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.

It is a common antirealist strategy to reject realism about some domain of entities for broadly epistemological reasons. When this strategy is applied to realism about moral facts, it takes something like the following form.

: 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.

It is commonly said of modern philosophy that it introduced a representative theory of perception, a theory that places representative mental items between perceivers and ordinary physical objects. Such a theory, it has been thought, would be a form of indirect realism: we perceive objects only by means of apprehending mental entities that represent them. The moral of the story is that what began with Descartes’s revolution of basing objective truth on subjective certainty ends with Hume’s paroxysms of ambivalence and (...) skepticism in the conclusion of the first book of the..

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. At the same time, his role in the Scottish Enlightenment is becoming much better understood. -/- This is the only properly established text. It is accompanied by manuscript lectures on the nature and immortality of the soul, as well as helpful editorial annotation and introduction, making it useful to a wide variety of readers. -/- Key Features: -/- Accurate, reliable and critically established text; The Introduction explains the work's genesis and its place in Reid's system; Annotations provide an understanding of Reid's context; An Appendix contains manuscript material covering an important topic not represented in the hitherto published work.

Thomas Reid is now recognized as one of the towering figures of the Enlightenment. Best known for his published writings on epistemology and moral theory, he was also an accomplished mathematician and natural philosopher, as an earlier volume of his manuscripts edited by Paul Wood for the Edinburgh Reid Edition, Thomas Reid on the Animate Creation, has shown. The Correspondence of Thomas Reid collects all of the known letters to and from Reid in a fully annotated form. Letters already published (...) by Sir William Hamilton and others have been reedited, and roughly half of the letters included appear in print for the first time. Writing in 1802, Reid's disciple and biographer Dugald Stewart doubted that Reid's correspondence &"would be generally interesting.&" This collection proves otherwise, for the letters illuminate virtually every aspect of Reid's life and career and, in some instances, provide us with invaluable evidence about activities otherwise undocumented in his manuscripts or published works. Through his correspondence we can trace Reid's relations with contemporaries such as David Hume and his colleagues at both King's College, Aberdeen, and the University of Glasgow, as well as his engagement with the most controversial philosophical, scientific, and political issues of his day. If anything, the letters assembled here serve as the starting point for understanding Reid and his place in the Enlightenment. (shrink)

I suggest a possible rehabilitation of Reid's philosophy of mind by a constructive use of Kant's criticisms of the common sense tradition. Kant offers two criticisms, explicitly claiming that common sense philosophy is ill directed methodologically, and implicitly rejecting Reid's view that there is direct epistemological access by introspection to the ontology of mind. Putting the two views together reveals a tension between epistemology and ontology, but the problem which Kant finds in Reid also infects his own system, as his (...) weaker ontological claims are undermined to such an extent by the necessary reintroduction of self-consciousness that the justification he seeks for reason fails to be reached epistemologically. Plausible solutions to these parallel tensions imply that both Reid and Kant have a pre-systematic concept of mind, and may lead to the conclusion that Reid's method is more economical in the elaboration of an ontology for the philosophy of mind.

The Scottish philosopher Thomas Reid first published Essays on Active Powers of Man in 1788 while he was Professor of Philosophy at King's College, Aberdeen. The work contains a set of essays on active power, the will, principles of action, the liberty of moral agents, and morals. Reid was a key figure in the Scottish Enlightenment and one of the founders of the 'common sense' school of philosophy. In Active Powers Reid gives his fullest exploration of sensus communis as the (...) basis of all philosophical inquiry. He uses common sense realism to argue for the existence of a stable external world, the existence of other minds, and to offer a powerful challenge to versions of the Theory of Ideas advocated by Hume and Locke . This is a key work of the Scottish Enlightenment that made important contributions to fundamental debates about the basis of philosophical inquiry. (shrink)

Thomas Reid was a philosopher who founded the Scottish school of 'common sense'. Much of Reid's work is a critique of his contemporary, David Hume, whose empiricism he rejects. In this work, written after Reid's appointment to a professorship at the university of Glasgow, and published in 1785, he turns his attention to ideas about perception, memory, conception, abstraction, judgement, reasoning and taste. He examines the work of his predecessors and contemporaries, arguing that 'when we find philosophers maintaining that there (...) is no heat in the fire, nor colour in the rainbow … we may be apt to think the whole to be only a dream of fanciful men, who have entangled themselves in cobwebs spun out of their own brain'. Written by one of the Scottish Enlightenment's most important thinkers, this work brings to life the intellectual debates of the time. (shrink)

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.

Chapter I: The Geometry of Visibles 1 . The N on- Euclidean Geometry of Visibles In the chapter "The Geometry of Visibles" in Inquiry into the Human Mind, ...

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)

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.

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.

Reid's unusual primary/secondary quality distinction is drawn along epistemic lines. Reid takes an epistemic turn because of Locke's failure to draw a metaphysical distinction. Secondary qualities differ from primary qualities in virtue of the fact that we acquire notions of secondary qualities via the mediation of sensations. Primary qualities require no such mediation. In one respect, the analysis I set out renders qualities relative to agents. I address whether Reid advocates a dispositional theory of secondary qualities, whether the phenomenology of (...) color underlying Reid's theory is tenable, and whether Reid's distinction coheres well with his theory of perceptual knowledge.

Thomas Reid, the Scottish natural and moral philosopher, was one of the founding members of the Aberdeen Philosophical Society and a significant figure in the Scottish Enlightenment. Reid believed that common sense should form the foundation of all philosophical inquiry. He criticised the sceptical philosophy propagated by his fellow Scot David Hume and the Anglo-Irish bishop George Berkeley, who asserted that the external world did not exist outside the human mind. Reid was also critical of the theory of ideas propagated (...) by Locke and Descartes, arguing that it was incompatible with physical and experiential facts. For Reid, our senses demonstrate that the external world must exist, and this work is organised in chapters examining each of the senses in turn. The book, based on his lectures, was first published in 1764 when Reid was a regent professor at King's College, Aberdeen, and was reissued in 1818. (shrink)

We can make a good prima facie case for the inconsistency of Reid's theory of perception with his rejection of the Ideal Theory. Most scholars believe Reid adopts a theory on which the immediate object of perception is a physical body. Reid is thought to do this in order to avoid problems generated by the veil of perception in the Ideal Theory, a conjunction of commitments Reid closely associates with Hume and Locke. Reid explains that the Ideal Theory "leans with (...) its whole weight upon a hypothesis...[t]hat nothing is perceived but what is in the mind which perceives it". Reid attributes to the Ideal Theory thesis. (shrink)

I argue that Reid adopts a form of Meinongianism about fictional objects because of, not in spite of, his common sense philosophy. According to 'the way of ideas', thoughts take representational states as their immediate intentional objects. In contrast, Reid endorses a direct theory of conception and a heady thesis of first-person privileged access to the contents of our thoughts. He claims that thoughts about centaurs are thoughts of non-existent objects, not thoughts about mental intermediaries, adverbial states or general concepts. (...) In part this is because of the common sense semantics he adopts for fictional-object terms. I show that it is reasonable for Reid to endorse Meinongianism, given his epistemological priorities, for he took the way of ideas to imply that his view about first-person privileged access to our mental contents was false.

Reid maintained that the perceptions that we obtain from the senses of smell, taste, hearing, and touch are ‘suggested’ by corresponding sensations. However, he made an exception for the sense of vision. According to Reid, our perceptions of the real figure, position, and magnitude of bodies are suggested by their visible appearances, which are not sensations but objects of perception in their own right. These visible appearances have figure, position, and magnitude, as well as ‘colour,’ and the standard view among (...) Reid scholars has been that Reid maintained that our perceptions of visible figure, position, and magnitude are also not suggested by any sensation. They are instead suggested by the material impression on the retina. Gideon Yaffe challenges the standard interpretation. According to Yaffe, Reid believed that our perceptions of visible figure are suggested by corresponding sensations, by sensations of colour. We defend the standard interpretation of Reid. According to Reid, there is no “local sign” in our sensations of colour. The same colour sensation can be associated with different positions on the visual field, and different colour sensations can be associated to the same position on the visual field. According to Reid, we only have evidence for a correlation between the image on the retina and the perception of visible figure. (shrink)

Thomas Reid was a persistent and acute critic of the philosophy of David Hume. It is Reid’s contention that Hume’s theory cannot account for the facts of human conception and belief. Hume’s theory is deficient in that impressions and ideas are inadequate to account for the intentionality of human thought, the fact that human thoughts have objects, ones that may not exist. Impressions and ideas are also inadequate to account for the facts of belief, especially the fact of negative belief. (...) Reid recognizes the genius of the attempt to account for human conception and belief in terms of impressions and ideas. He calls Hume the most acute metaphysician of the age and remarked, in correspondence, that if Mr. Hume were to stop writing, he and his cohorts in Aberdeen would have nothing to discuss. Reid remarks as well, however, that it is genius and not the lack of it that leads to false philosophy. Reid is not a mere modus tollens critic of Hume. Unlike G. E. Moore, Reid does not rest content with arguing that Hume’s theory cannot account for the facts but contends that we need not despair of a better. Reid’s philosophy is an attempt to offer a better theory. I shall describe Reid’s destructive and constructive efforts to refute the philosophy of Hume. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume XXIII, Number 2, November 1997, pp. 315-335 Reid: Conception, Representation and Innate Ideas ROGER D. GALLIE Section I of this paper begins with a presentation of Thomas Reid's doctrine of the signification of words, of what words signify or represent. That presentation serves to introduce a problem of interpretation, namely, what Reid thinks the connection is between conceiving something and grasping what a term for it (...) signifies. It is pointed out that even if Reid maintains that what a word signifies is conceived by both speaker and hearer when that word is understood, this is a far cry from the position that he takes the stronger view, whether for all or only for some things, that their being conceived involves the understanding of a term or terms. The position that he does indeed take this stronger, although moderate, view is defended in sections II, III and IV. In sections II and III it is argued that, in Reid's view, for an adequate conception of an individual, real or imaginary, a conception of its attributes is needed. In section IV it is argued that the possession of general conceptions (in distinction from their formation), without which conception of attributes is impossible, requires appropriate understanding of general terms. So since for the conception of an individual a conception of its attributes is needed, and since for the conception of attributes appropriate understanding of general terms is required, we arrive at a textually well-founded position: for the conception of most things, in Reid's view, understanding of terms is indispensable.

Gallie The remainder of the paper considers the following question: to what extent, if any, Reid is committed to acceptance of nativist views on concept possession? To answer, in section V we consider to what extent Reid's moderate position on the possession of conceptions commits him to accepting Jerry Fodor's representational theory of mind (RTM) for propositional attitudes. It is clear that the view that a propositional attitude state such as belief involves some relation between a person and a representation such as a significant word, phrase or sentence of a natural language such as English can fairly be attributed to Reid. But it is also clear that Reid cannot be an adherent of the view that persons have a functional cum computational relation to Fodorean mental representations, so he cannot be an adherent of any nativism ex- plicitly contained in such a view. But it is to be noted that in his Inquiry, Chapter IV, Reid argues by a different route that in order to acquire a language such as English prior mastery of a system of significant signs is required. In section VI Keith Lehrer's argument in criticism of a reductionist interpretation of a position such as Fodor's is presented: that for a sign to signify something to someone presupposes that that person has a conception of what is signified. It is however pointed out that since there is a case for not viewing Fodor's position as reductionist overall Fodor can accept Lehrer's argument. Lehrer's innatist position, which he both claims to follow easily from this critical argument and to be a correct interpretation of Reid, is then presented: that we must presuppose an innate understanding of some signs to account for our learning the meaning of any signs. The objection that Reid too must accept the alleged innatist implications of Lehrer's critical argument in view of the implications of his moderate position on the possession of conceptions is considered and rebutted. In section VIII argue that while Lehrer makes a respectable case for innate principles of formation of conceptions such as that of hardness, something that Reid clearly endorses in his Inquiry, Chapter V, he does not succeed in making a case for there being any innate possession of conceptions. Finally, in section VIII, Reid's mature views in the Intellectual Powers, Essay VI, on how conceptions come to be possessed are expounded, and are fleshed out with some... (shrink)

This paper contrasts three different positions taken by 18th century British scholars on how sensations, particularly sensations of colour and touch, come to be localized in space: Berkeley’s view that we learn to localize ideas of colour by associating certain purely qualitative features of those ideas with ideas of touch and motion, Hume’s view that visual and tangible impressions are originally disposed in space, and Reid’s view that we are innately disposed to refer appearances of colour to the end of (...) a line passing through the centre of the eye and originating from the spot on the back of the retina where the material impression causing that appearance was received. Reid’s reasons for rejecting the Berkeleian and Humean views are examined. It is argued that Reid’s position on visual localization is ultimately driven by his dualistic metaphysical commitments rather than by an empirically grounded investigation of the phenomena of vision. To this extent, his position sits uncomfortably with his own methodological commitments. (shrink)

(Originally published in _Reid Studies_ 4 (2000-01): 35-51.) Reid and Berkeley disagreed over whether we directly perceive objects located outside of us in a surrounding space, commonly revealed by both vision and touch. Berkeley considered a successful account of erect vision to be crucial for deciding this dispute, at one point calling it ‘the principal point in the whole optic theory.’ Reid's critique of Berkeley's position on this topic is very brief, and appears to miss Berkeley's point. I argue that (...) there is more to Reid's response to Berkeley than at first meets the eye. Reid's rival account of erect vision draws on evidence that makes a compelling case for the position that we see the same space that we touch. (shrink)

This paper considers an objection to the Humean view that perception involves introspective acquaintance with representative images. The objection, originally raised by Thomas Reid and recently endorsed by Nicholas Wolterstorff, states that no representative image can be hard, and concludes that acquaintance with such images cannot therefore account for our perception of hardness. I argue in response that a case has not been made for denying that representative images can be hard. Hardness, as understood by Hume and Reid, is the (...) quality of having parts that resist motion relative to one another. This means that as long as it is allowed that representative images can consist of spatially disposed parts, there can be no a priori reason to deny that they might be hard as well. (shrink)
