On Anger - Seneca

What room is there for anger? Everything ought either to move us to tears or to laughter. The wise man will not be angry with sinners. Why not? Because he knows that no one is born wise, but becomes so: he knows that very few wise men are produced in any age, because he thoroughly understands the circumstances of human life. Now, no sane man is angry with nature: for what should we say if a man chose to be surprised that fruit did not hang on the thickets of a forest, or to wonder at bushes and thorns not being covered with some useful berry? No one is angry when nature excuses a defect.
