" Gibbs’ introduction of probability into physics occurred well before there was an adequate theory of the sort of probability he needed. But for all these gaps it is, I am convinced, Gibbs rather than Einstein or Heisenberg or Planck to whom we must attribute the first great revolution of twentieth century physics. This revolution has had the effect that physics now no longer claims to deal with what will always happen, but rather with what will happen with an overwhelming probability. At the beginning in Gibbs’ own work this contingent attitude was superimposed on a Newtonian base in which the elements whose probability was to be discussed were systems obeying all of the Newtonian laws.
