Thomas Henry Huxley Quote

Uniformitarinism, on the other hand, has with equal justice [to Catastrophism] insisted upon a practically unlimited bank of time, ready to discount any quantity of hypothetical paper. It has kept before our eyes the power of the infinitely little, time being granted, and has compelled us to exhaust known causes, before flying to the unknown.
