Both in thought and in feeling, even though time be real, to realise the unimportance of time is the gate of wisdom.

Have no respect for the authority of others, for there are always contrary authorities to be found

Those whose lives are fruitful to themselves, to their friends, or to the world are inspired by hope and sustained by joy: they see in imagination the things that might be and the way in which they are to be brought into existence.

...I am afraid that education is conceived more in terms of indoctrination by most school officials than in terms of enlightenment. My own belief is that education must be subversive if it is to be meaningful. By this I mean that it must challenge all the things we take for granted, examine all accepted assumptions, tamper with every sacred cow, and instill a desire to question and doubt. Without this the mere instruction to memorise data is empty. The attempt to enforce conventional mediocrity on the young is criminal.

Broadly speaking, we are in the middle of a race between human skill as a means and human folly as an end.
