Science and art,... they seek the truth and the meaning of life, they seek God, [and] the soul, and when they are harnessed to passing needs and activities,... then they only complicate and encumber life.
To judge between good or bad, between successful and unsuccessful would take the eye of a God.
The wealthy are always surrounded by hangers-on; science and art are as well.
The more refined one is, the more unhappy.
Knowledge is of no value unless you put it into practice.
A good upbringing means not that you won't spill sauce on the tablecloth, but that you won't notice it when someone else does.
