Lust is also a Desire for and Love of joining one body to another.

Exp.: Whether this Desire for sexual union is moderate or not, it is usually called Lust.

Moreover, these five affects (as I pointed out in P56 S) have no opposites. For Courtesy is a species of Ambition (see P29 S), and I have already pointed out also that Moderation, Sobriety, and Chastity indicate the power of the Mind, and not a passion. And even if it can happen that a greedy, ambitious, or timid man abstains from too much food, drink, and sexual union, still, Greed, Ambition, and Timidity are not opposites of gluttony, drunkenness, or lust.

For the greedy man generally longs to gorge himself on another’s food and drink. And the ambitious will not be moderate in anything, provided he can hope he will not be discovered; if he lives among the drunken and the lustful, then because he is ambitious, he will be the more inclined to these vices. Finally, the timid man does what he does not wish to do. For though he may hurl his wealth into the sea to avoid death, he still remains greedy. And if the lustful man is sad because he cannot indulge his inclinations, he does not on that account cease to be lustful.
