Such was the standpoint and view of classical physics, which latter certainly had a right to see what it could make of it. All that is left to determinism is to believe that an infinite accumulation of observations would in principle enable it completely to determine the system. But in practice a finite number of observations is all that we can make. "If nature is more complicated than a game of chess, a belief to which one tends to incline, then a physical system cannot be determined by a finite number of observations. As soon, however, as the great majority or possibly all of these laws are seen to be of a statistical nature, they cease to provide a rational argument for the retention of determinism. In favor of the latter it could be urged that this ancient habit demonstrably rested on the actual laws which we observe functioning in our surroundings. The former was favored by ancient custom, or possibly by an a priori belief. "Fifty years ago it was simply a matter of taste or philosophic prejudice whether the preference was given to determinism or indeterminism. Several years later, Schrödinger presented a paper on "Indeterminism in Physics" to the June, 1931 Congress of A Society for Philosophical Instruction in Berlin. ( ‘ What Is a Law of Nature?,’ Science and the Human Temperament, p.142.) In a Laplacian world, there is only one possible future. Pierre-Simon Laplace was first to see in his "calculus of probabilities" a universal law that determined the motions of everything from the largest astronomical objects to the smallest particles. They thought that we simply lack the knowledge necessary to make exact predictions for these individual events. The "bell curve" or "normal distribution" of random outcomes was itself so consistent that they argued for underlying deterministic laws governing individual events. The macroscopic irreversibility of entropy increase depends on Boltzmann's molecular chaos which depends on the randomness in microscopic irreversibility.īefore the twentieth century, most physicists, mathematicians, and philosophers believed that the chance described by the calculus of probabilities was actually completely determined. Boltzmann used intrinsic randomness in molecular collisions (molecular chaos) to derive the increasing entropy of the Second Law of Thermodynamics. Exner, who was himself a colleague of the great Ludwig Boltzmann at the University of Vienna. In his early career, Schrödinger was a great exponent of fundamental chance in the universe.
