The Fire Within Noble Souls — Letters from a Stoic

The noble soul cannot rest at the level of ordinary things, and this is not a flaw but a feature. Letter 39 opens with a request from Lucilius for a concise summary of Stoic teachings, and Seneca redirecting him: read the list of philosophers who have worked for your benefit. That act alone will rouse you. The great soul is like a flame, it springs straight into the air, cannot be held down or made to rest quietly.

The more ardent it is, the greater its motion. But the letter quickly turns to the opposite danger: what happens when the soul is given too much. Too rich a soil makes grain fall flat. Branches break under too heavy a load.

Excessive prosperity doesn't ripen, it rots. The same is true of pleasure: men who overindulge reach a point where what was once superfluous becomes indispensable. They are slaves to pleasures they believe they enjoy.

They love their own ills, and that, Seneca says, is the worst ill of all. The height of unhappiness is reached when vices have become habits, when there is no longer room for a cure, when shameful things not only attract but please.
