Computing Methodologies -- Artificial Intelligence.

Imagine that you and a duplicate of yourself are lying unconscious, next to each other, about to undergo a complete step-by-step exchange of bits of your bodies. It certainly seems that at no stage in this exchange of bits will you have thereby switched places with your duplicate. Yet it also seems that the end-result, with all the bits exchanged, will be essentially that of the two of you having switched places. Where will you awaken? I claim that one and (...) the same person possesses both bodies, occupies both places and will experience both awakenings, just as a person whose brain has been bisected must at once experience both of the unconnected fields of awareness, even though each of these will falsely appear to him as the entirety of his experience. I also claim that the more usual apparent boundaries of persons are as illusory as those in brain bisection; personal identity remains unchanged through any variation or multiplication of body or mind. In all conscious life there is only one person - I - whose existence depends merely on the presence of a quality that is inherent in all experience - its quality of being mine, the simple immediacy of it for whatever is having experience. One powerful argument for this is statistical: on the ordinary view of personhood it is an incredible coincidence for you (though not for others) that out of 200,000,000 sperm cells the very one required on each occasion for your future existence was first to the egg in each of the begettings of yourself and all your ancestors. The only view that does not make your existence incredible, and that is not therefore (from your perspective) an incredible view, is that any conscious being would necessarily have been you anyway. It is a consequence that self-interest should extend to all conscious organisms. (shrink)

The functionalist view of the nature of the mind is now widely accepted. Like behaviorism and physicalism, functionalism seeks to answer the question "What are mental states?" I shall be concerned with identity thesis formulations of functionalism. They say, for example, that pain is a functional state, just as identity thesis formulations of physicalism say that pain is a physical state.

The question what makes us human is often treated as a question of fact. However, the term 'human' is not primarily used to refer to a particular kind of entity, but as a 'nomen dignitatis' -- a dignity-conferring name. It implies a particular moral status. That is what spawns endless debates about such issues as when human life begins and ends and whether human-animal chimeras are "partly human". Definitions of the human are inevitably "persuasive". They tell us about what is (...) important and how we should live our lives as humans, and thus help us to make sense of what we are. (shrink)

What will happen to us--after we teach our computers and robots to think? In this compelling book, two bestselling authors, a paleontologist and an artificial intelligence guru, take a controversial look at computer technology in the 21st century. They present the sociological, theological, and scientific issues that we will face, when brains are downloaded into receptacles and machines are more efficient than humans.
