Those that vow the most are the least sincere.

My education was the liberty I had 

to read indiscriminately 

and all the time, 

with my eyes hanging out.

It is your work in life that is the ultimate seduction.

Science is all metaphor.

Life is the farce which everyone has to perform.

There is no greater joy than that of feeling oneself a creator. 

The triumph of life is expressed by creation.

We are all in the gutter, 

but some of us are looking at the stars.

Words are but symbols for the relations of things to one another 

and to us; 

nowhere do they touch upon absolute truth.

Always the beautiful answer who asks a more beautiful question.

There are some good rules 

and there are some lousy rules.

The beginning of knowledge is the discovery of something we do not understand.

Progress is man's ability to complicate simplicity.

It is better to err on the side of daring than the side of caution.

In the world of words, the imagination is one of the forces of nature.

You must be the change you wish to see in the world.
