See and keep silent.

I call God to witness that as a private person I have done nothing unbeseeming an honest man, nor, as I bear the place of a public man, have I done anything unworthy of my place.

There is less danger in fearing too much than too little.

Knowledge is never too dear.

The man dies in all who keep silent in the face of tyranny.

What's ill-got scarce to a third heir descends, nor wrongful booty meets with prosperous ends.
