Extropianism, also referred to as the philosophy of ''Extropy'', is an evolving framework of values and standards for continuously improving the human condition. Extropians believe that advances in science and technology will some day let people live indefinitely. An extropian may wish to contribute to this goal, e.g. by doing research and development or volunteering to test new technology. Extropianism describes a pragmatic consilience of transhumanist thought guided by a proactionary approach to human evolution and progress. Originated by a set of principles developed by Dr. Max More, ''The Principles of Extropy'', extropian thinking places strong emphasis on rational thinking and practical optimism. According to More, these principles "do not specify particular beliefs, technologies, or policies". Extropians share an optimistic view of the future, expecting considerable advances in computational power, life extension, nanotechnology and the like. Many extropians foresee the eventual realization of indefinite lifespans, and the recovery, thanks to future advances in biomedical technology or mind uploading, of those whose bodies/brains have been preserved by means of cryonics. ==Extropy== The term 'extropy', as an antonym to 'entropy' was used in a 1967 academic volume discussing cryogenics〔''Cryogenics'', IPC Science and Technology Press, vol. 7, pg. 225 (1967)〕 and in a 1978 academic volume of cybernetics.〔Proceedings of the Fourth International Congress of Cybernetics & Systems: "Current Topics in Cybernetics and Systems", pg. 258 (1978)〕 Diane Duane was the first to use the term "extropy" to signify a potential transhuman destiny for humanity.〔Duane, Diane. "The Wounded Sky" (1983)〕 'Extropy' as coined by Tom Bell (T.O. Morrow) and defined by Max More in 1988, is "the extent of a living or organizational system's intelligence, functional order, vitality, energy, life, experience, and capacity and drive for improvement and growth." Extropy is not a rigorously defined technical term in philosophy or science; in a metaphorical sense, it simply expresses the opposite of entropy. A more recent definition of Extropy has been provided by Kevin Kelly, senior maverick at Wired magazine. "Extropy is neither wave, nor particle, nor pure energy. It is a non-material force that is very much like information. Since Extropy is defined as negative entropy-the reversal of disorder-it is, by definition, an increase in order." Kelly gives this definition of extropy in his research on the evolution of technology. In the philosophy of digital probabilistic physics, the extropy of a physical system is defined to be the self-information of the Markov chain probability of the physical system at a moment in time. This was to distinguish the probability of the Markov state of the physical system from the probability defined by entropy which creates ensembles of equivalent microstates. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Extropianism」の詳細全文を読む スポンサード リンク
