This book both introduces the philosophy of science through examination of the occult and examines the occult rigorously enough to raise central issues in the philosophy of science. Placed in the context of the occult, philosophy of science issues become immediately understandable and forcefully compelling. Divergent views on astrology, parapsychology, and quantum mechanics mysticism emphasize topics standard to the philosophy of science. Such issues as confirmation and selection for testing, causality and time, explanation and the nature of scientific laws, the status of theoretical entities, the problem of demarcation, theory and observation, and science and values are discussed. Significantly revised, this second edition presents an entirely new section of quantum mechanics and mysticism including instructions from N. David Mermin for constructing a device which dramatically illustrates the genuinely puzzling phenomena of quantum mechanics. A more complete and current review of research on astrology has been included in this new edition, and the section on the problem of demarcation has been broadened

A version of this paper was presented at the IEEE International Conference on Computational Intelligence, combined meeting of ICNN, FUZZ-IEEE, and ICEC, Orlando, June-July, 1994, and an earlier form of the result is to appear as "The Undecidability of the Spatialized Prisoner's Dilemma" in Theory and Decision . An interactive form of the paper, in which figures are called up as evolving arrays of cellular automata, is available on DOS disk as Research Report #94-04i . An expanded version appears as chapter 6 of The Philosophical Computer.

John Abbruzzese has recently attempted a defense of omniscience against a series of my attacks. This affords me a welcome occasion to clarify some of the arguments, to pursue some neglected subtleties, and to re-think some important complications. In the end, however, I must insist that at least three of four crucial arguments really do show an omniscient being to be impossible. Abbruzzese sometimes misunderstands the forms of the argument themselves, and quite generally misunderstands their force.

'Post-critical,' as Echeverria rightly notes, "is one of those catchy, yet slippery phrases which seem to crop up in so many places that they take on a power of their own." But for the purposes of this study, at least, he manages to circumscribe the topic with remarkable clarity: "... the traditional meaning of a critique of knowledge excluded reflection on one's own historical context as an essential trait of philosophical theories, and relegated that context to psychology. 'Post-critical' philosophy wants to reinstate that historical context as one that must itself necessarily be included in the very idea of theory or, as the case may be, of philosophical criticism."

The goal of philosophy of information is to understand what information is, how it operates, and how to put it to work. But unlike ‘information’ in the technical sense of information theory, what we are interested in is meaningful information. To understand the nature and dynamics of information in this sense we have to understand meaning. What we offer here are simple computational models that show emergence of meaning and information transfer in randomized arrays of neural nets. These we take to be formal instantiations of a tradition of theories of meaning as use. What they offer, we propose, is a glimpse into the origin and dynamics of at least simple forms of meaning and information transfer as properties inherent in behavioral coordination across a community.

Eliseo Vivas's intellectual life started at the political left and within the tradition of American naturalism, and has ended up somewhere to the political right and with some form of anti-naturalism. Vivas also started "with a great deal of cocksure confidence about his knowledge of the ills of society and the nature of the universe" and ended up recognizing that "he knew very little besides the fact that he did not know, because genuine knowledge about these matters does not exist". This book, written in the form of a biography of one Alonzo Quijano, is an intimate intellectual memoir of the changes in political attitude and philosophical conviction that went between. A flirtation with communism in the thirties and various political squabbles within academia are presented as stages on life's way, and serve as background for freely rambling discussions of naturalism, liberalism, the origin of man, ethical and aesthetic values, ultimate mysteries, and the nature and limits of philosophy.
