We become wiser by adversity; prosperity destroys our appreciation of the right.
What you do for an ungrateful man is thrown away.
A benefit consists not in what is done or given, but in the intention of the giver or doer.
We are more easily led part by part to an understanding of the whole. -Facilius per partes in cognitionem totius adducimur
When modesty has once perished, it will never revive.
There is no genius without a mixture of madness.
