"The road that leads to pleasure is downhill and very easy, with the result that one does not walk but is dragged along; the other which leads to self-control is uphill, toilsome no doubt but profitable exceedingly. The one carries us away, forced lower and lower as it drives us down its steep incline, till it flings us off on to the level ground at its foot; the other leads heavenwards the immortal who have not fainted on the way and have had the strength to endure the roughness of the hard ascent."
