...the test of a first-rate intelligence is the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function. One should, for example, be able to see that things are hopeless and yet be determined to make them otherwise. This philosophy fitted on to my early adult life, when I saw the improbable, the implausible, often the "impossible," come true.
Animals learn death first at the moment of death;...man approaches death with the knowledge it is closer every hour, and this creates a feeling of uncertainty over his life, even for him who forgets in the business of life that annihilation is awaiting him. It is for this reason chiefly that we have philosophy and religion.
Such philosophy as shall not vanish in the fume of subtile, sublime, or delectable speculation but shall be operative to the endowment and betterment of man's life.
Genius is its own reward; for the best that one is, one must necessarily be for oneself. . . . Further, genius consists in the working of the free intellect., and as a consequence the productions of genius serve no useful purpose. The work of genius may be music, philosophy, painting, or poetry; it is nothing for use or profit. To be useless and unprofitable is one of the characteristics of genius; it is their patent of nobility.
Socrates was the first to call philosophy down from the heavens and to place it in cities, and even to introduce it into homes and compel it to inquire about life and standards and goods and evils.
My teaching is not a philosophy. It is the result of direct experience...
My teaching is a means of practice, not something to hold onto or worship.
My teaching is like a raft used to cross the river.
Only a fool would carry the raft around after he had already reached the other shore of liberation.
So far there has been no philosopher in whose hands philosophy has not grown into an apology for knowledge; on this point, at least, every one is an optimist, that the greatest usefulness must be ascribed to knowledge. They are all tyrannized over by logic, and this is optimism in its essence.
