“The deeper we get into reality, the more numerous will be the questions we cannot answer.”

“The golden rule is, to help those we love to escape from us.”

“To save all we must risk all.”

“We must make the building of a free society once more an intellectual adventure, a deed of courage.... Unless we can make the philosophic foundations of a free society once more a living intellectual issue, and its implementation a task which challenges the ingenuity and imagination of our liveliest minds, the prospects of freedom are indeed dark.

“Few people ever have an abundance of choice of occupation. But what matters is that we have some choice, that we are not absolutely tied to a job which has been chosen for us, and that if one position becomes intolerable, or if we set our heart on another, there is always a way for the able, at some sacrifice, to achieve his goal. Nothing makes conditions more unbearable than the knowledge that no effort of ours can change them; and even if we should never have the strength of mind to make the necessary sacrifice, the knowledge that we could escape if we only strove hard enough makes many otherwise intolerable positions bearable.”

“It is because every individual knows little and, in particular, because we rarely know which of us knows best that we trust the independent and competitive efforts of many to induce the emergence of what we shall want when we see it.”
