What psychological and philosophical significance should we attach to recent efforts at computer simulations of human cognitive capacities? In answering this question, I find it useful to distinguish what I will call "strong" AI from "weak" or "cautious" AI. According to weak AI, the principal value of the computer in the study of the mind is that it gives us a very powerful tool. For example, it enables us to formulate and test hypotheses in a more rigorous and precise fashion. (...) But according to strong AI, the computer is not merely a tool in the study of the mind; rather, the appropriately programmed computer really is a mind, in the sense that computers given the right programs can be literally said to.

The strong continuity thesis postulates that the properties of mind are an enriched version of the properties of life, and thus that life and mind differ in degree and not kind. A philosophical problem for this view is the ostensive discontinuity between humans and other animals in virtue of our use of symbols—particularly the presumption that the symbolic nature of human cognition bears no relation to the basic properties of life. In this paper, we make the case that a genuine (...) account of strong continuity requires the identification of some sort of correlate of symbol-use in basic life properties. Our strategy is three-fold: 1) we argue that examples of proto-symbolism in simple living systems would be consistent with an evolutionary trajectory that ultimately produced symbolic cognition in humans; 2) we introduce Gordon Tomkins’ biological notion of ‘symbol’ as something that represents to the organism a feature of its environment that is significant to its survival; and 3) we employ this biological understanding of symbol-use to suggest that the symbolic nature of human cognition can be understood as an enriched version of the basic symbolic properties of life, thus preserving life-mind continuity in this context.

With the clarity that James deemed obligatory, Some Problems of Philosophy outlines his theory of perception. The early chapters expose the defects of intellectualism and monism and the advantages of empiricism and pluralism. The novelty that enters into concrete perceptual experience, and that is disallowed by the rationalizing intellect, suggests exciting possibilities. Denied any absolute truth in an ever-changing world, privy to only a piece of the truth at any given moment, the individual can, with faith and good will, help (...) create order out of chaos. Some Problems in Philosophy, published posthumously, represents an important advance in William James’s thought. (shrink)
