Henri Poincaré, French mathematician and physicist

“If all the parts of the universe are interchained in a certain measure, any one phenomenon will not be the effect of a single cause, but the resultant of causes infinitely numerous; it is, one often says, the consequence of the state of the universe the moment before.” (from “The Measure of Time” in “The Value of Science,” 1905)
