Tom Reid

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

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.

The past few years have seen a revival of interest in Thomas Reid's philosophy. His moral theory has been studied by D. D. Raphael (The Moral Sense) and his entire philosophical position by S. A. Grave (The Scottish Philosophy of Common Sense). Prior to both, A. D. Woozley gave us the first modern reprint of Reid's Essays on the Intellectual Powers of Man - in fact the first edition of any work by Reid to appear in print since the Philosophical Works was edited in the nineteenth century by Sir William Hamilton. But Reid's aesthetic philosophy has not received its due. Woozley, in abridging the Essays, omitted the whole final essay, "On Taste," which is the only extended work on aesthetic theory that Reid ever published. Raphael, being interested primarily in Reid's moral theory, understand ably, treated aesthetics only as it was related to morality. And Grave, although he did present a short and very cogent resume of Reid's aes thetic position, obviously found himself drawn to other elements of Reid's philosophy. There are, of course, some accounts of Reid's aes thetic theory to be found in the various studies of eighteenth-century British aesthetics and criticism. None, however, appears to me to do any kind of justice to the philosophical questions which Reid treats in his aesthetics and philosophy of art.

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.

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.

The Essays on the Active Powers of Man was Thomas Reid's last major work. It was conceived as part of one large work, intended as a final synoptic statement of his philosophy. The first and larger part was published three years earlier as Essays on the Intellectual Powers of Man. These two works are united by Reid's basic philosophy of common sense, which sets out native principles by which the mind operates in both its intellectual and active aspects. The Active Powers shows how these principles are involved in volition, action, and the ability to judge morally. Reid gives an original twist to a libertarian and realist tradition that was prominently represented in eighteenth-century British thought by such thinkers as Samuel Clarke and Richard Price.

Written in 1792 and not previously published, this essay sets out Reid's considered view of the nature of agency and the related idea of natural causation. Locke is wrong in supposing that the idea of power is acquired through external or internal experience, Hume in supposing that because it is not got through outer or inner sense we have no such idea. The primary conception of power is that of personal agency, got from the experienced fact that certain events are produced when we will to produce them. The concept of cause is related to this through the experience of the efficacy of volitional power. The problem, then, is what to make of the idea that nature contains non‐volitional causes. An orderly world implies the operation of an intelligent agent. The idea of agency proper implies two‐way operation, e.g., to be possessed of the power of walking is thereby to be possessed of the power of not walking. So a power does not necessitate a certain outcome, and what we think of as necessitating natural causes are related to natural regularities, rather than part of the idea of causality as such.

Thomas Reid, contemporary and philosophical foe of David Hume, was the chief figure in the group of philosophers constituting the Scottish school of common sense. Between 1753 and 1762, Reid delivered four "Philosophical Orations" at graduation ceremonies at King's College, Aberdeen. This is the first English translation of those Latin orations, which reveal Reid's philosophical opinions during his formative years. Reid's influence was strong in America until the middle of the 19th century. Thomas Jefferson was a convert to the commonsense philosophy of Reid and his school, and for the first dozen academic generations after the revolutionary war, American students were steeped in the thought of Reid and his associates. Thus Reid profoundly influenced American political, literary, and philosophical culture. His philosophy served as a cornerstone of American education.
