The viewpoint that consciousness, including feeling, could be fully expressed by a computational device is known as strong artificial intelligence or strong AI. Here I offer a defense of strong AI based on machine-state functionalism at the quantum level, or quantum-state functionalism. I consider arguments against strong AI, then summarize some counterarguments I find compelling, including Torkel Franzén’s work which challenges Roger Penrose’s claim, based on Gödel incompleteness, that mathematicians have nonalgorithmic levels of “certainty.” Some consequences of strong AI are (...) then considered. A resolution is offered of some problems including John Searle’s Chinese Room problem and the problem of consciousness propagation under isomorphism. (shrink)

Anselm’s ontological argument for the existence of God is examined. It is concluded that Anselm errs in assuming the greatest "thing" must be a sentient being. The existence of God, then, is not established by Anselm’s argument, and is concluded to be unlikely for other reasons as well, one being that a perfected sentient being would be a logical impossibility. An afterlife and personal immortality are not precluded however; these goals could be reached by future scientific means. For now cryonics (...) is advocated as a means to reach a more advanced future when death may be physically overcome. (shrink)
