Francis Bacon

There is a wisdom in this beyond the rules of physic: a man’s own observation what he finds good of and what he finds hurt of is the best physic to preserve health.

There is a difference between happiness and wisdom: he that thinks himself the happiest man is really so but he that thinks himself the wisest is generally the greatest fool.

Silence is the sleep that nourishes wisdom.

Wise men make more opportunities than they find.

A prudent question is one-half of wisdom.

It is impossible to love and to be wise.
