I endeavor to keep their attention fixed on the main objects of all science, the freedom & happiness of man.

Agriculture is our wisest pursuit, because it will in the end contribute most to real wealth, good morals, and happiness.

Politics, like religion, hold up the torches of martyrdom to the reformers of error.

He who receives an idea from me, receives instruction himself without lessening mine; as he who lights his taper at mine, receives light without darkening me.
