The prestige of the Nobel Prize is due to many causes, but in particular to its twofold idealistic and international character: idealistic in that it has been designed for works of lofty inspiration; international in that it is awarded after the production of different countries has been minutely studied and the intellectual balance sheet of the whole world has been drawn up. Free from all other considerations and ignoring any but intellectual values, the judges have deliberately taken their place in what the philosophers have called a community of the mind.

Only those ideas that are least truly ours can be adequately expressed in words.

It is with our entire past ... that we desire, will and act ... from this survival of the past it follows that consciousness cannot go through the same state twice. The circumstances may still be the same, but they will act no longer on the same person ... that is why our duration is irreversible.

Men do not sufficiently realize that their future is in their own hands. Theirs is the task of determining first of all whether they want to go on living or not. Theirs is the responsibility, then, for deciding if they want merely to live, or intend to make just the extra effort required for fulfilling, even on this refractory planet, the essential function of the universe, which is a machine for the making of gods.

The universe... is a machine for the making of gods.

In reality, the past is preserved by itself automatically.
