forces opposing entropy. it represents boundless expansion, self-transformation, dynamic optimism, intelligent technology, and spontaneous order.

A term used to denote the tendency of systems to grow more organised, in opposition to the entropy expectation. Also called 'ectropy', 'enformy', 'negentropy' or 'syntropy' (or more generally 'self-organization'). The reasons for this are partly the motivation behind Complexity Theory.

A measure of intelligence, information, energy, life, experience, diversity, opportunity, and growth. The collection of forces which oppose entropy. (Also a extropian quarterly magazine, see the Extropy Home Page) [T.O. Morrow, 1988

The term extropy, coined by Tom Bell (T. O. Morrow) in January 1988, is defined as 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 expresses a metaphor, rather than serving as a technical term, and so is not simply the opposite of entropy.
