text: Let us, therefore, rouse ourselves, that we may be able to correct our mistakes. Philosophy, however, is the only power that can stir us, the only power that can shake off our deep slumber. Devote yourself wholly to philosophy. You are worthy of her; she is worthy of you; greet one another with a loving embrace. Say farewell to all other interests with courage and frankness. Do not study philosophy merely during your spare time.
