A single lie destroys a whole reputation for integrity.

Keep expectation alive. Keep stirring it up. Let much promise more, and great deeds herald greater.

Know what is evil, no matter how worshipped it may be. Let the man of sense not mistake it, even when clothed in brocade, or at times crowned in gold, because it cannot thereby hide its hypocrisy, for slavery does not lose its infamy, however noble the master.

There is no revenge like oblivion, for it is the entombment of the unworthy in the dust of their own nothingness.

Make your friends your teachers and mingle the pleasures of conversation with the advantages of instruction.

Knowledge without courage is sterile.

He that can live alone resembles the brute beast in nothing, the sage in much, and God in everything.
