Thomas Reid has a theory of consciousness that is central to his philosophy of mind but which raises a regress problem. I have two tasks in this paper. The first is to give an account of Reid's views on consciousness and the avoidance of the regress based on textual analysis. The second is to expand the theory of consciousness Reid gives to offer a deeper explanation of how the regress is avoided that is based on Reid's philosophy of mind but goes beyond any text from Reid that I know. The distinction is important. Philosophers are inclined to attribute to a philosopher views that they have invented by studying the philosopher. Both textual analysis and invention based on a philosopher's writings are legitimate uses of the history of philosophy. When they are confused, however, arguments about what the philosopher held generate confusion. If you invent something from his or her philosophy, even something implied by it, that is your philosophy, not the philosopher's. The distinction is important for avoiding useless disputes. This first part of my paper is an attempt to remain true to the texts of Reid. The second part goes beyond the text, though it is what I extrapolate from Reid.

Thomas Reid claims to share Locke's view that consciousness is a kind of inner sense. This is puzzling, given the role the inner-sense theory plays in indirect realism and in the theory of ideas generally. I argue that Reid does not in fact hold an inner-sense theory of consciousness and that his view differs importantly from contemporary higher-order theories of consciousness. For Reid, consciousness is a first-order representational process in which a mental state with a particular content suggests the application of recognitional concepts in forming beliefs or judgements to the effect that one is currently undergoing a state with that content. I take up the question of whether Reid's theory leads to a regress, and I argue that while the regress cannot be eliminated, it is mitigated by the non-hierarchical nature of Reid's theory of mind.

As an advocate of the empirical method in both science and philosophy, Reid believed that the central method for studying the mind should be internal observation, whose evidence he believed to be the most reliable in comparison with all other mental operations. The fact that his contemporary “science of mind” was not as highly developed as the natural sciences was explained by Reid to be the fault of philosophers, such as John Locke, who “confounded” two completely different powers of the mind: consciousness and reflection. In this paper I will present Reid's criticism of Locke, as well as Reid's own attempt to distinguish between consciousness and reflection, and the difficulties he is facing in this process. The paper concludes that Reid failed to depart from the essential Lockean characterizations of inner awareness, because of his failure to dissociate from premises he shares with Locke – such as the belief that we are conscious of all our thoughts, and the primacy of the introspective method in studying the mind. Therefore, while narrowing his concept of consciousness to an internal-sense, perceiving only present mental operations, he broadens respectively his concept of reflection.

There is a problem about the compatibility of Reid's commitment to both a sign theory of sensations and also direct realism. I show that Reid is committed to three different senses of the claim that mind independent bodies and their qualities are among the immediate objects of perception, and I then argue that Reid's sign theory conflicts with one of these. I conclude by advocating one proposal for reconciling Reid's claims, deferring a thorough development and defence of the proposal to another paper.

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. There is no other book that both uncovers the deep pattern of Reid's thought and relates it to contemporary philosophical debate.

Building on the research of Manfred Kuehn, the author argues that, whatever influence the Scottish Common Sense Philosophy of Thomas Reid may have had on the development of Immanuel Kant’s refutation of idealism, it was filtered through the thinking of Kant’s largely forgotten German contemporary, Johann Nicolaus Tetens. While the importance of Tetens for understanding Kant is examined in connection with only one idea, the aim is to demonstrate that Tetens is a figure worthy of serious historical consideration.

Reid said little in his published writings about his contemporary Joseph Priestley, but his unpublished work is largely devoted to the latter. Much of Priestley's philosophical thought- his materialism, his determinism, his Lockean scientific realism- was as antithetical to Reid's as was Hume's philosophy in a very different way. Neither Reid nor Priestley formulated a full response to the other. Priestley's response to Reid came very early in his career, and is marked by haste and immaturity. In his last decade Reid worried much about Priestley's materialism, but that concern never reached publication. I document Reid's unpublished response to Priestley, and also view Reid's response from Priestley's perspective, as deduced from his published works. Both thinkers attempted to base their arguments on Newtonian method. Reid's position is the more puzzling of the two, since he nowhere makes clear how Newtonian method favours mind-body dualism over materialism, which is the central debate between them.

In the chapter “The Geometry of Visibles” in his ‘Inquiry into the Human Mind’, Thomas Reid constructs a special space, develops a special geometry for that space, and offers a natural model for this geometry. In doing so, Reid “discovers” non-Euclidean Geometry sixty years before the mathematicians. This paper examines this “discovery” and the philosophical motivations underlying it. By reviewing Reid’s ideas on visible space and confronting him with Kant and Berkeley, I hope, moreover, to resolve an alleged impasse in Reid’s philosophy concerning the contradictory characteristics of Reid’s tangible and visible space.

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.
