The genius of any single man can no more equal learning, than a private purse hold way with the exchequer.

You can't be more horrific than life itself.

Science is but an image of the truth.

Rather to excite your judgment briefly than to inform it tediously.

Some artists leave remarkable things which, a 100 years later, don't work at all. I have left my mark; my work is hung in museums, but maybe one day the Tate Gallery or the other museums will banish me to the cellar... you never know.

The cause and root of nearly all evils in the sciences is this-that while we falsely admire and extol the powers of the human mind we neglect to seek for its true helps.

Do not wonder if the common people speak more truly than those above them: they speak more safely.
