“If we are to have intense pleasures, we must also be liable to intense pains. The pleasure we love, and the pain we hate, but it seems impossible to have the former without the latter. Indeed, it looks as if the two must in some way alternate, for continuous pleasure is a stimulus that must either pall or be increased. And the increase will either harden the sense buds with its friction, or turn into pain. A consistent diet of rich food either destroys the appetite or makes one sick.”
