Organic evolution has its physical analogue in the universal law that the world tends, in all its parts and particles, to pass from certain less probable to certain more probable configurations or states. This is the second law of thermodynamics. It has been called the law of evolution of the world; and we call it, after Clausius, the Principle of Entropy, which is a literal translation of Evolution in Greek.
