Lust is an intense desire or craving, especially for sexual activity. It can take many forms, such as the lust for knowledge, the lust for power and of course, the lust for sex.
Lust is disordered desire for or inordinate enjoyment of sexual pleasure. Sexual pleasure is morally disordered when sought for itself, isolated from its procreative and unitive purposes.
Of woman's unnatural, insatiable lust, what country, what village doth not complain?
Robert Burton, The Anatomy of Melancholy (1621), Pt. 3. Sec. 2.
They exercise genital acts, yet prevent the conceiving of children. Not in order to produce offspring, but to satisfy lust, are they eager for corruption.
Neither do thou lust after that tawney weed tobacco.
Ben Jonson, Bartholomew Fair (1614), Act II, scene vi
Lust is the offspring of a thousand sighs, Intrigue, deception, and as many lies; A strange compound of hidden, plotting ill, "To fire with rage, to torture, or to kill.
Foeda est in coitu et brevis voluptas, et taedet Veneris statim peractae.
Delight of lust is gross and brief And weariness treads on desire.
Petronius, reported in The Concise Oxford Dictionary of Quotations (1981), p. 183
Here do you keep a hundred knights and squires; Men so disorder’d, so debosh’d and bold That this our court, infected with their manners, Shows like a riotous inn. Epicurism and lust Makes it more like a tavern or a brothel Than a grac’d palace.
A serving-man, proud in heart and mind; that curled my hair; wore gloves in my cap; served the lust of my mistress' heart, and did the act of darkness with her; swore as many oaths as I spake words, and broke them in the sweet face of heaven: one that slept in the contriving of lust, and waked to do it: wine loved I deeply, dice dearly: and in woman out-paramoured the Turk: false of heart, light of ear, bloody of hand; hog in sloth, fox in stealth, wolf in greediness, dog in madness, lion in prey. Let not the creaking of shoes nor the rustling of silks betray thy poor heart to woman: keep thy foot out of brothels, thy hand out of plackets, thy pen from lenders' books, and defy the foul fiend.
Do not lust in your heart after her beauty or let her captivate you with her eyes, for the prostitute reduces you to a loaf of bread, and the adulteress preys upon your very life.
Proverbs 6:25-26 (NIV)
Whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
