There is nothing unequal as the equal treatment of unequals.

Nothing in life is more necessary than friendship.

When we deliberate it is about means and not ends.

No one who desires to become good will become good unless he does good things.

That rule is the better which is exercised over better subjects.

It is the mark of an educated mind to rest satisfied with the degree of precision which the nature of the subject admits and not to seek exactness where only an approximation is possible.
