Nationalism is an infantile disease. It is the measles of mankind.

Mysticism is in fact the only criticism people cannot level against my theory.

When Albert Einstein was asked what he would really like to know about the Universe he replied,'is it friendly?

[There is] a duty in refusing to cooperate in any undertaking that violates the Constitutional rights of the individual. This holds in particular for all inquisitions that are concerned with the private life and the political affiliations of the citizens.

Schools need not preach political doctrine to defend democracy. If they shape men capable of critical thought and trained in social attitudes, that is all that is necessary.

[When asked "Dr. Einstein, why is it that when the mind of man has stretched so far as to discover the structure of the atom we have been unable to devise the political means to keep the atom from destroying us?"] That is simple, my friend. It is because politics is more difficult than physics.

Those who have the privilege to know have the duty to act.
