20 But suppose that some one remains unharmed, free from grief, in uninterrupted enjoyment of the pleasures of the whole course of man's life, what comfort can the soul attain to, enclosed in the bonds of a body of such a kind, and restrained by the narrow limits of the limbs? If our flesh shrinks from prison, if it abhors everything which denies it the power of roaming about; when it seems, indeed, to be always going forth, with its little powers of hearing or seeing what is beyond itself, how much more does our soul desire to escape from that prison-house of the body, which, being free with movement like the air, goes whither we know not, and comes whence we know not.
