there are two lines of influence of David Hume on the history of classical American pragmatism: the familiar atomist-nominalist-associationist of empirical psychology reviled by Kantian and idealist critics, on the one side, and the conjectural historian and early developmentalist, or evolutionary, philosopher who was important to Darwin, on the other. The classical pragmatists received the first most directly through the work of Thomas Hill Green, in his edition of the Treatise of Human Nature—with its long critical introduction—that appeared in the (...) 1870s. In this essay I argue that the atomist of the traditional reading is a false Hume, with the hope that identification of the error will make way for a better... (shrink)

Charles Darwin and C. Lloyd Morgan forward two influential principles of cognitive ethological inference that yield conflicting results about the extent of continuity in the cognitive traits of humans and other animals. While these principles have been interpreted as reflecting commitments to different senses of parsimony, in fact, both principles result from the same vera causa inferential strategy, according to which “We ought to admit no more causes of natural things, than such as are both true and sufficient to explain (...) their appearances”. Instead, the conflict stems from Darwin’s and Morgan’s views about the true causes of human psychology. Darwin holds a thoroughly Humean philosophy of the human mind, from which he infers significant continuity between human and animal minds. In contrast, Morgan argues that Humean cognitive mechanisms cannot account for a class of uniquely human behaviors, and therefore, he concludes that there is a significant discontinuity between human and animal cognition. This historical debate is informative for current controversies in comparative psychology. (shrink)
