“災變論”是一種地質或生物學理論(與 uniformitarianism 相對),始於1869年,由 T.H.赫胥黎創造,由 catastrophe 和 -ism 組成。相關詞彙: Catastrophist。
By CATASTROPHISM I mean any form of geological speculation which, in order to account for the phenomena of geology, supposes the operation of forces different in their nature, or immeasurably different in power, from those which we at present see in action in the universe. [Huxley, "Address" to the Geological Society of London, Feb. 19, 1869]
“災變論”是指任何形式的地質學推測,爲了解釋地質現象,假設存在與我們目前在宇宙中看到的力量在性質上不同或力量上無法估量的力量。[赫胥黎,“致倫敦地質學會的演講”,1869年2月19日]
