Any power must be an enemy of mankind which enslaves the individual by power and by force, whether it arises under the Fascist or the Communist flag. All that is valuable in human society depends upon the opportunity for development accorded to the individual.
By academic freedom I understand the right to search for truth and to publish and teach what one holds to be true. This right implies also a duty; one must not conceal any part of what one has recognized to be true.
Everything should be made as simple as possible, but not simpler.
Great spirits have always found violent opposition from mediocrities. The latter cannot understand it when a man does not thoughtlessly submit to hereditary prejudices but honestly and courageously uses his intelligence.
I have never looked upon ease and happiness as ends in themselves - such an ethical basis I call more proper for a herd of swine. The ideals which have lighted me on my way and time after time given me new courage to face life cheerfully, have been Truth, Goodness, and Beauty.

The prestige of government has undoubtedly been lowered considerably by the Prohibition law.

A human being is a part of the whole, called by us, "Universe," a part
limited in time and space. He experiences himself, his thoughts and
feelings as something separated from the rest -- a kind of optical delusion
of his consciousness. This delusion is a kind of prison for us, restricting
us to our personal desires and to affection for a few persons nearest to
us. Our task must be to free ourselves from this prison by widening our
circle of compassion to embrace all living creatures and the whole of
nature in its beauty. Nobody is able to achieve this completely, but the
striving for such achievement is in itself a part of the liberation and a
foundation for inner security.
