In 1792 Dugald Stewart published Elements of the philosophy of the human mind. In its section on abstraction he declared himself to be a nominalist. Although a few scholars have made brief reference to this position, no sustained attention has been given to the central role that it played within Stewart’s early philosophy of mind. It is therefore the purpose of this essay to unpack Stewart’s nominalism and the intellectual context that fostered it. In the first three sections I aver (...) that his nominalism emanated from his belief that objects of the mind—qualities, ideas and words—were signs that bore no necessary relation to the external objects that they were meant to represent. More specifically, it was these signs that were arranged into systems of thought by the ‘operations of the mind’. The next three sections suggest that his treatment of words as signs most probably originated in his views on language and medicine and that his nominalistic philosophy of mind could also be extended to systems that sought to classify the natural world. I conclude by suggesting several avenues of enquiry that could be pursued by future scholars interested in excavating Stewart’s thought. (shrink)

According to Reid, color sensations are not extended nor are they arranged in figured patterns. Reid further claimed that ‘there is no sensation appropriated to visible figure.’ Reid justified these controversial claims by appeal to Cheselden's report of the experiences of a young man affected by severe cataracts, and by appeal to cases of perception of visible figure without color. While holding fast to the principle that sensations are not extended, Dugald Stewart tried to show that ‘a variety of colour (...) sensations is a necessary means for the perception of visible figure.’ According to John Fearn, two motives appear to be central to Reid's views about color sensations and extension: his commitment to the Cartesian doctrine of the immateriality of the soul, and his attempt to evade ‘Hume's dilemma’ about the existence and immateriality of the soul.

Describing the will and the extent of its causal power over human actions, Joseph Priestley famously compared the mind to a stone, as both are subject to deterministic laws: “Though an inclination...

Thomas Reid has the unusual distinction of arriving at a metaethical position very much like G. E. Moore’s via a route very similar to that employed by the Kantians. That is, Reid embraces a version of nonnaturalist moral realism by appeal not to open question-style considerations but to a particular account of agency. In this essay, we reconstruct Reid’s agency-centered argument for his constitutivist version of moral nonnaturalism, highlighting its commitments. Having presented Reid’s argument, we close by considering a prominent (...) contemporary Kantian view, namely, Christine Korsgaard’s, and identifying where, despite their common commitments, Reid and Korsgaard part company. The comparison, we suggest, is instructive because it allows us to see more clearly why the link between agency-centered approaches to ethical theorizing and nonrealist, constitutivist views of morality, such as Korsgaard’s, is deeply contingent.

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.

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.

Thomas Reid, Adam Ferguson and Dugald Stewart were exponents of the experimental philosophy of mind in the Scottish Enlightenment. The unique character of their philosophical project lies in the adoption of the mind-matter dualism as a necessary condition for the study of mental phenomena. This fact led them to recognize the importance of Descartes, both for being the first to clearly delimit the mental and material realms and for emphasizing the relevance of reflection as an instrument for the study of (...) mind. But at the same time, the Frenchman was also the target of their criticism for dismissing the value of experimentation and appealing to hypotheses to explain natural behaviour. This paper aims to review this group of Scottish philosophers’ views of the mind, explaining, at the same time, the reasons for their ambivalent attitude towards Descartes. In order to make sense of this ambivalence, I will argue that it is useful to bear in mind two different aspects of the methodology that the Scots put forward to study mental phenomena: firstly, the one between analogy and reflection and, secondly, the one between induction and hypothesis making.

En la segunda mitad del siglo XVIII tuvo lugar un debate entre Thomas Reid y Joseph Priestley acerca de la naturaleza de la mente y su interacción con el cuerpo. En el marco de la defensa de la religión cristiana y en nombre de principios metodológicos experimentalistas y newtonianos, los autores defienden propuestas radicalmente diferentes acerca de la relación entre la mente y la materia. Sus divergencias se vinculan con la interpretación del método newtoniano y su concepción de la materia, (...) lo que delineará dos actitudes: una dualista, de carácter más conservador por parte de Reid y una materialista, heterodoxa e innovadora por parte de Priestley.

This paper answers two interpretive questions surrounding belief in God in Thomas Reid’s philosophy, the status question and the detachability question. The former has to do with the type of justification Reid assigns to belief in God – immediate or mediate. The later question is whether anything philosophically significant depends on his belief in God. I argue that, for Reid, belief in God is immediately justified and integral to some parts of his system. Reid’s response to skepticism about God is (...) more complicated and more interesting than many of the contemporary philosophers who, citing Reid as inspiration, also hold that belief in God enjoys immediate justification. In Reid’s hands the approach to belief in God does not compete with inferential justification, does not rely on a special faculty, and foregrounds the developmental character of his epistemology.

My paper offers a new interpretation of Reid’s account of social operations of the mind. I argue that it is important to acknowledge the counterpart structure of social operations. By this I mean that for Reid every social operation is paired with a counterpart operation. On the view that I ascribe to Reid, at least two intelligent beings take part in a social operation and the social operation does not come into existence until both the social operation and its counterpart (...) operation have been exercised and the relevant mental thoughts made known to the other being by words or signs.

We argue that there is no tension between Reid's description of science and his claim that science is based on the principles of common sense. For Reid, science is rooted in common sense since it is based on the idea that fixed laws govern nature. This, however, does not contradict his view that the scientific notions of causation and explanation are fundamentally different from their common sense counterparts. After discussing these points, we dispute with Cobb's and Benbaji's interpretations of Reid's (...) views on causation and explanation. Finally, we present Reid's views from the perspective of the contemporary debate on scientific explanation. (shrink)

This essay traces the development of the philosophical debates concerning active powers and human agency in eighteenth-century Scotland. I examine how and why Scottish philosophers such as Francis Hutcheson, George Turnbull, David Hume, and Henry Home, Lord Kames, depart from John Locke’s and other traditional conceptions of the will and how Thomas Reid and Dugald Stewart reinstate Locke’s distinction between volition and desire. Moreover, I examine what role desires, passions, and motives play in the writings of these and other Scottish (...) Enlightenment philosophers on human agency and draw attention to their underlying disputes concerning liberty and necessity. I end by reflecting on how classifications of principles of actions changed in eighteenth and early nineteenth-century Scottish philosophy. (shrink)

This paper is a reconstruction and analysis of Thomas Reid’s epistemology, based upon an examination of his extant manuscripts and publications. I argue that, in Reid’s view, a certain degree of “evidence” (or, as I shall say, ‘epistemic justification’) is that which distinguishes mere true belief from knowledge; and that this degree of justification may be ascribed to a person’s belief if and only if (i) the evidence upon which her belief is grounded is such that she holds it with (...) “certainty”; (ii) she has a “sound understanding”; (iii) she has a distinct conception of the object of her belief; and, finally, (iv) she has formed her belief “without prejudice”.
