Thermodynamics, correctly interpreted, does not just allow Darwinian evolution; it favors it.

It must be splendid to command millions of people in great national ventures, to lead a hundred thousand to victory in battle. But it seems to me greater still to discover fundamental truths in a very modest room with very modest means - truths that will still be foundations of human knowledge when the memory of these battles is painstakingly preserved only in the archives of the historian.

Since a given system can never of its own accord go over into another equally probable state but into a more probable one, it is likewise impossible to construct a system of bodies that after traversing various states returns periodically to its original state, that is a perpetual motion machine.

In my view all salvation for philosophy may be expected to come from Darwin's theory

Which is more remarkable fact about America: that millionaires are idealists or idealists become millionaires.

Thermodynamics, correctly interpreted, does not just allow Darwinian evolution; it favors it.

Nothing is more practical than a good theory.
