But
I must explain to you how all this mistaken idea of denouncing pleasure
and praising pain was born and I will give you a complete account of
the system, and expound the actual teachings of the great explorer of
the truth, the master-builder of human happiness.
No one rejects, dislikes, or avoids pleasure itself, because it is
pleasure, but because those who do not know how to pursue pleasure
rationally encounter consequences that are extremely painful.
Nor again is there anyone who loves or pursues or desires to obtain
pain of itself, because it is pain, but because occasionally
circumstances occur in which toil and pain can procure him some great
pleasure. To take a trivial example, which of us ever undertakes
laborious physical exercise, except to obtain some advantage from it?
