Seneca,
Moral letters to Lucilius — Letter 39…
“ No man of exalted gifts is pleased with that which is low and mean; the vision of great achievement summons him and uplifts him. 3. Just as the flame springs straight into the air and cannot be cabined or kept down any more than it can repose in quiet, so our soul is always in motion, and the more ardent it is, the greater its motion and activity. But happy is the man who has given it this impulse toward better things! ”
