In this article I trace some of the main tenets of the struggle between nominalism and realism as identified by John Deely in his Four ages of understanding. The aim is to assess Deely’s claim that the Age of Modernity was nominalist and that the coming age, the Age of Postmodernism — which he portrays as a renaissance of the late middle ages and as starting with Peirce — is realist. After a general overview of how Peirce interpreted the nominalist-realist (...) controversy, Deely gives special attention to Thomas Aquinas’s On being and essence and the realism it entails. A subsequent discussion of the Modern Period shows that the issue of nominalism and realism is very much tied up with di¤erent conceptions of the intellect. Deely credits the theory of evolution with bringing us a conception of the intellect that is closer to that of the Middle Ages and that opens the way for a truly realistic ‘‘fourth age’’ of the understanding.

This paper considers the relation between the American pragmatist Charles Sanders Peirce and the German idealist G. W. F. Hegel . While Peirce engaged with Hegel’s thought quite extensively, his often critical comments on the latter have made it hard to see any genuine common ground between the two; recent ways of reading Hegel, however, suggest how this might be possible, where the connections between their respective metaphysical positions and views of the categories are explored here. Issues relating to their (...) epistemology and philosophies of languages are considered in a companion article. (shrink)

Peirce's references to Ockham are less frequent and less fulsome both in detail and in praise than his references to Scotus. And if one expects a critique of “the greatest nominalist that ever lived” to be especially revealing, they are also somewhat disappointing. Nevertheless, the comparison and contrast with Ockham offers another occasion to examine the “question of nominalism and realism” which Peirce thought to be so important.

For many years, Charles Peirce maintained that all senses of the modal terms "possible" and "necessary" can be defined in terms of "states of information." But in 1896, he was motivated by his work in set theory to criticize that account of modality, and in 1905 he characterized that criticism as a return "to the Aristotelian doctrine of a real possibility ... the great step that was needed to render pragmaticism an intelligible doctrine." But since Peirce was a realist about (...) modality before 1896, and since he continued defining "possibility" in terms of "states of information" after that date, it is not clear exactly what he changed his mind about. In this essay I explain what it was that Peirce changed his mind about and why, in retrospect, he viewed that change as a decisive step in the development of pragmaticism. (shrink)

In this paper, which is the second in a series, I continue to consider the relation between the American pragmatist Charles Sanders Peirce and the German idealist G. W. F. Hegel. This article focuses on their views of epistemology and inquiry, and their accounts of the relation between language and thought. As with the earlier paper, it is argued that fruitful similarities between their positions on these issues can be found.
