Is lust in action; and till action, lust
Is perjured, murd'rous, bloody, full of blame,
Savage, extreme, rude, cruel, not to trust;
Enjoyed no sooner but despised straight;
Past reason hunted, and no sooner had,
Past reason hated as a swallowed bait,
On purpose laid to make the taker mad;
Mad in pursuit, and in possession so,
Had, having, and in quest to have, extreme;
A bliss in proof, and proved, a very woe;
Before, a joy proposed; behind, a dream.
All this the world well knows, yet none knows well
To shun the heaven that leads men to this hell.
(Shakespeare)
