Violent pleasures which reach the soul through the body are generally of this sort-they are reliefs of pain.
PlatoDo not train children to learning by force and harshness, but direct them to it by what amuses their minds.
PlatoAll soul is immortal. For that which is always in movement is immortal; that which moves something else, and is moved by something else, in ceasing from movement ceases from living. So only that which moves itself, because it does not abandon itself, never stops moving. But it is also source and first principle of movement for the other things which move.
Plato
