A learned man is an idler who kills time with study. Beware of his false knowledge: it is more dangerous than ignorance.

All great truths begin as blasphemies.

Beware of the man whose God is in the skies.

Do not do unto others as you would that they should do unto you. Their tastes may not be the same.

Take care to get what you like or you will be forced to like what you get.

The longer I live the more I see that I am never wrong about anything, and that all the pains I have so humbly taken to verify my notions have only wasted my time.
