Human action can be modified to some extent, but human nature cannot be changed.

The things I want to know are in books; my best friend is the man who'll get me a book I ain't read.

He who has a thousand friends has not a friend to spare,

A man must consider what a rich realm he abdicates when he becomes a conformist.

Accept the place the divine providence has found for you, the society of your contemporaries, the connection of events.

What you are thunders so loudly in my ears that I cannot hear what you say. What you do rings so loudly in my ears that I cannot hear what you say.

A man's action is only a picture book of his creed.

We must be worshipers of the light of Truth, from whatever lamp it shines.

It is kindness in a person, not beauty that wins our love

How vain it is to sit down to write when you have not stood up to live!
