I wash my hands of those who imagine chattering to be knowledge, silence to be ignorance, and affection to be art.

There are those who give with joy, and that joy is their reward.

You cannot have youth and the knowledge of it at the same time; For youth is too busy living to know, and knowledge is too busy seeking itself to live.

I have learned silence from the talkative, toleration from the intolerant, and kindness from the unkind; yet, strange, I am ungrateful to those teachers.

Perplexity is the beginning of knowledge.

The person you consider ignorant and insignificant is the one who came from God, that he might learn bliss from grief and knowledge from gloom.
