My art and profession is to live.

Any time and any place can be used to study: his room, a garden, is table, his bed; when alone or in company; morning and evening. His chief study will be Philosophy, that Former of good judgement and character who is privileged to be concerned with everything.

To say less of yourself than is true is stupidity, not modesty. To pay yourself less than you are worth is cowardice and pusillanimity.

One must be a little foolish if one does not want to be even more stupid.

Once conform, once do what others do because they do it, and a kind of lethargy steals over all the finer senses of the soul.

I have never seen a greater monster or miracle in the world than myself.

Wonder is the foundation of all philosophy; research, the progress; ignorance, the end. There is, by heavens, a strong and generous kind of ignorance that yields nothing, for honour and courage, to knowledge: an ignorance to conceive which needs no less knowledge than to conceive knowledge.
