“In recent times, more and more human thinking has come to assume that the idea of a universal natural law and the idea of 'God' are pointing to one and the same reality.”

“Nothing is more powerful than an idea whose time has come.”

“The idea that one will die is more painful than dying, but less painful than the idea that another person is dead, that, becoming once more a still, plane surface after having engulfed a person, a reality extends, without even a ripple at the point of disappearance from which that person is excluded, in which there no longer exists any will, any knowledge, and from which it is as difficult to reascend to the idea that that person has lived as, from the still recent memory of his life, it is to think that he is comparable with the insubstantial images, the memories, left us by the characters in a novel we have been reading.”

“More powerful than the mighty armies is an idea whose time has come.”

“More powerful than kings and armies is an idea whose time has come to move.”

“The more one analyses people, the more all reasons for analysis disappear. Sooner or later one comes to that dreadful universal thing called human nature.”
