The noblest pleasure is the joy of understanding.

For, verily, great love springs from great knowledge of the beloved object, and if you little know it, you will be able to love it only little or not at all.

You do ill if you praise, but worse if you censure, what you do not understand.

The acquisition of knowledge is always of use to the intellect, because it may thus drive out useless things and retain the good. For nothing can be loved or hated unless it is first known.

Those who, in debate, appeal to their qualifications, argue from memory, not from understanding.

The most beautiful words of love are told in silence for a look.
