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 unlimited maximum life spans, 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.
The term 'extropy', as an antonym to 'entropy' was used in a 1967 academic volume discussing cryogenics and in a 1978 academic volume of cybernetics. Diane Duane was the first to use the term "extropy" to signify a potential transhuman destiny for humanity.'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.
Extropism is a modern derivative of the transhumanist philosophy of Extropianism. It follows in the same tradition, hence the similarity of name, but has been revised to better suit the paradigms of the 21st century. As introduced in The Extropist Manifesto, it promotes an optimistic futuristic philosophy that can be summed up in the following five phrases, which spell out the word "EXTROPISM":
• Endless eXtension
• Transcending Restriction
• Overcoming Property
• Intelligence
• Smart Machines
These five key points, when taken together, formulate a philosophy and world view which embraces bio-ethical abolitionism, life extension, singularitarianism, technogaianism, freedom of information and several other related disciplines and philosophies. While it does not make a firm political stance, it is most closely related to libertarian socialism (given that it supports the abolition of money and property). Philosophically, it draws from the philosophy of Jeremy Bentham and utilitarianism.
Extropists desire to prolong their life span to a near-immortal state and exist in a world where artificial intelligence and robotics have made work irrelevant.[citation needed] As in utilitarianism, the purpose of one's life should be to increase the overall happiness of all creatures on Earth through cooperation.
The Extropist Manifesto, written by Breki Tomasson and Hank Hyena of The Extropist Examiner in January 2010 (site since discontinued), details the ways in which Extropism has evolved away from, while building upon the original tenets of Extropianism. For example, it moves away from the original Extropian Principles by placing a significant focus on the need to abolish and/or restrict the current use of surveillance, copyright and patent laws. This philosophy, inspired in part by the philosophy of the International Pirate Party, is one of the five basic tenets of the Extropist philosophy, falling under the category "Overcoming Property". Other noteworthy topics that appear frequently in Extropist writings is the focus on equal rights for LGBT couples and individuals and a general distaste for organized religiosity.
