First Extropy ad (T.O. Morrow)
The first extropy advertisement, used by Tom Bell and Max More in the Fall of 1988 to promote the first few issues of their journal. [5]
In hmolscience, extropy is a metaphorical entropy antonym term, conceived as the opposite of entropy, signifying progressive movements into the future; which has somewhat trickled into new age discussions.

In 1967, or before Harry Overstreet, American naturalist humanist philosopher, introduced the term "extropy" as a counter-entropy quantity (see: entropy antonyms), which he defined as involving truth and beauty and goodness, would be expected to lead inevitably to god. [9]

One of the first mentions of the term extropy as a book title is the 1984 book Mythematics and Extropy, a work that seems to be associated with Polish poet Boleslaw Lesmian, who is noted for a number of neologisms.

Independently, it seems the term was coined, originating via analogy, by American lawyer-philosopher Tom Bell in 1988. [1] Max More, Bell's accociate, defines extropy as a "metaphor, loosely related to the idea of negentropy, that refers to basic attitudes and values shared by those who want to overcome human limits". [6] In 2010, when queried as to “the history behind adopting the term extropy, particularly in relation to either entropy or thermodynamics, as a type of philosophy?”, Tom Bell suggested the web archive Extropian FAQ page gave the best overview.

People considered to be adherents of the principles of extropy is called an "extropian" and the ideology or philosophy study of the subject is called "extropianism"

Extropy magazine
In August, of 1988, Bell together with English-American philosopher Max More started the printed journal Extropy, in which the term “extropy” was coined to define “the opposite of entropy or of thermodynamic decay”. [2] In the years to follow the term, both with and without thermodynamic qualifiers, slowly trickled into public use.


In 1999, American physican Karlis Ullis, within his theory of exercise physiology human thermodynamics, defined extropy as a state of antientropy, which leads to the building of organized biological structures, the ultimate blueprint that calls for sexual maturation and reproduction. [3]

New age
In recent years, the term has come be associated with a creative force or élan vital, which is regarded by the new age and techno-utopian communities as generating novelty, breeding complexity, producing insights, and countering the forces of entropy. In this ideology, extropy is associated with the set of natural health products or ways of life, which mediate a type of force of extropy, that promote holistic well-being as they act to counter the entropic threat or degeneration. [4] These types of analogy uses, however, seem to have no rigorous connection to fundamental thermodynamics.

Novelty theory
A recent popular search term is novelty vs extropy, which seems to be a revival of something called “novelty theory”, supposedly, developed by American new age philosopher Terence McKenna, which proposes that the universe is an engine designed for the production and conservation of novelty. Novelty, in this context, can be thought of as newness, or extropy (supposedly borrowed from Max More’s meaning of the opposite of entropy). Some kind of laymanized view holds that, in a nutshell, novelty theory involves ontology, extropy, and eschatology. According to McKenna, when novelty is graphed over time, a fractal waveform known as "timewave zero" or simply the "timewave" results. The graph shows at what time periods, but never at what locations, novelty increases or decreases and is supposed to represent a model of history's most important events. The original publication for his view remains to be tracked down. [8]
