Seneca,
Moral letters to Lucilius — Letter 113…
“ Then how can you infer that Justice is a living thing? "Justice," people reply, "is active and helpful; that which acts and is helpful, possesses impulse; and that which possesses impulse is a living thing."

Every living thing exists as it began, until death; a man, until he dies, is a man, a horse is a horse, a dog a dog. They cannot change into anything else. Now let us grant that Justice – which is defined as "a soul in a certain attitude," is a living thing. ”
