The Role of Scepticism in Modern Philosophy Reconsidered

The Role of Scepticism in Modern Philosophy Reconsidered RICHARD H. POPKIN THE THEORY that the revival of ancient scepticism, and the application of its arguments to the controversies of the sixteenth century, played a vital role in the development of modern philosophy was first suggested by me almost forty years ago. A three-part article in the Review of Metaphysics entided "The Sceptical Crisis and the Rise of Modern Philosophy" contained much of the theory.' What was added by the time of my History of Scepticism from Erasmus to Descartes (published in x96o,' but finished by 1958 ) was the importance of the sceptical arguments in the controversies of the Reformation and the CounterReformation , and the development of a religious scepticismmfideism--as a way of fending off criticism of basic religious beliefs.s One of the first reviews of my book was by Charles B. Schmitt,4 which he soon followed with his volume on Gianfrancesco Pico and then one on Cicero Scepticus.5 Before Charles Schmitt and I entered this arena, scepticism as a living philosophical view was hardly mentioned in histories of philosophy, which, by and large, saw modern philosophy as a rejection of Scholasticism, with nothing in between. One leaped from William of Ockham and Duns Scotus to Francis Bacon and Descartes, with perhaps a momentary nod to Montaigne as an amus- ' R. H.

There were practically no articles about or studies of scepticism as a philosophical attitude or activity in modern philosophy before we went to work. The American philosopher Roderick Chisholm had written an article on Sextus and modern empiricism, and that was about it.6 When I took my first course in the history of philosophy with John Herman Randall, I frankly could not make much out of Plato or Aristotle, but when we were assigned to read Sextus Empiricus, I found an author who made sense. Later in the course I was introduced to Hume, whom Randall hated, and I loved. In a course with Paul Oskar Kristeller a few years later, on Hellenistic philosophy, Sextus appeared as a serious figure. A couple of years after that, in a seminar with Charles Hendel on Hume, I wrote a paper on Sextus and Hume. I showed it to Kristeller, who said drily and carefully that it might be worth looking into whether Hume had read Sextus, and whether there was a prior tradition of scepticism in European philosophy. Thus was I set off on the quest. Schmitt and I not only offered a lot of evidence previously ignored or unknown about the recovery of sceptical texts and their use in the philosophical discussions of the sixteenth and early seventeenth centuries, but we also offered a new paradigm, a new way of conceiving what problems were being agitated, a new way of understanding the kinds of answers being given as ways of resolving the sceptical crisis. The reception of our theory indicated that it provided a more meaningful picture of the making of the modern mind than what had previously been proposed.7 What I should like to deal with now are three questions: Has our theory stood up over almost four decades? Has it had to be revised or amended? And does it need to be expanded (as I have been doing) to encompass another kind of scepticism, that directed against traditional religion from about...
