Knowledge is never too dear.

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

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.

See and keep silent.

For knowledge, too, is itself a power. [Lat., Nam et ipsa scientia potestas est.]

Knowledge bloweth up, but charity buildeth up.
