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.

Hegel’s idea of dialectic has permeated much of our thinking, especially in the guise of a process of development, and hence it is important to understand it. This paper suggests three things. First, there is more agreement between Hegel’s deepest ideas and those of Dooyeweerd than at first might be expected. We find that Hegel is reaching towards what Dooyeweerd takes as his starting point. Therefore, second, applying Dooyeweerd’s ideas can enrich Hegel’s and suggest three fundamentally different types of dialectic. (...) Third, Dooyeweerd’s concept of irreducible aspects provides an explanation of the dialectic process: an engine, and one that has advantages over other proposals. This is illustrated with the development of environmental thinking. (shrink)
