单词 actualism
释义
actualism
Geology and Earth Sciences

  • The theory that present-day processes provide a sufficient explanation for past geomorphological phenomena, although the rate of activity of these processes may have varied. The theory was first clearly expressed in 1749 by G. L. L. Buffon (1707–88), and was the essential principle of uniformitarianism as presented in 1830 by C. Lyell (1797–1875).

Geography

  • The supposition that no biological and geological processes other than those operating today have operated in the past. However, H. G. Reading (1978) observes that ‘the majority of past environments differ in some respects from modern environments. We must therefore be prepared, and have the courage, to develop non-actualistic models, unlike any that exist today’.

Philosophy

  • Sometimes known as actual idealism. For one usage see Gentile. The term also applies in contemporary works to the view that only the actual world is real, with other possible worlds regarded as not themselves existing, but as wrongly thought to exist because modal idioms are useful instruments of thought about the real world. See also modal realism, Vaihinger.
