Fear and the Natural Response — Letters from a Stoic

Courage doesn't make you immune to the body's instinctive responses. Letter 57 opens with Seneca making his way back to Naples through the dark, dust-choked tunnel at Posillipo, torches dim, air suffocating, mud and grit everywhere. He emerges unsettled, though not afraid, and uses that subtle distinction to make one of his most careful arguments. There are feelings that no courage can prevent. The brave man flinches at a sudden noise.

He grows dizzy at a precipice's edge. He changes colour in the dark. These aren't failures of will, they're the body reminding the mind how perishable it is. Some soldiers who readily shed their own blood cannot bear to see someone else's.

Some meet the sword-stroke more easily than they watch it being dealt. The point isn't to condemn these reactions but to locate them correctly: they live in the body, not in the character. The letter closes with a meditation on the soul's escape from the body at death. Just as fire escapes from the edges of whatever tries to crush it, just as air flows back around any object placed in its way, the soul, subtler than fire, will find its way out through any gap.

It cannot be crushed. And if it survives, it cannot be harmed.
