Thomas Reid often seems distant from other Scottish Enlightenment figures. While Hume, Hutcheson, Kames, and Smith wrestled with the nature of social progress, Reid was busy with natural philosophy and epistemology, stubbornly loyal to traditional religion and ethics, and out of touch with the heart of his own intellectual world. Or was he? I contend that Reid not only engaged the Scottish Enlightenment's concern for improvement, but, as a leading interpreter of Isaac Newton and Francis Bacon, he also developed a (...) scheme to explain the progress of human knowledge. Pulling thoughts from across Reid's corpus, I identify four key features that Reid uses to distinguish mature sciences from prescientific arts and inquiries. Then, I compare and contrast this scheme with that of Thomas Kuhn in order to highlight the plausibility and originality of Reid's work. (shrink)

I examine the views of Thomas Reid with respect to a certain version of the problem of induction: Why are inductions using natural kinds successful, and what justifies them? I argue that while both Reid holds a kind of conventionalist view about natural kinds, this conventionalism has a realistic component which allows him to answer both questions.
