Editing Lust (section)

==In philosophy==
The link between [[love]] and lust has always been a problematic question in philosophy.

===Schopenhauer===
[[Schopenhauer]] notes the misery which results from [[sexual relationship]]s. According to him, this directly explains the sentiments of shame and sadness which tend to follow the act of sexual intercourse; for, he states, the only power that reigns is the inextinguishable desire to face, at any price, the blind love present in human existence without any consideration of the outcome. He estimates that a genius of his species is an industrial being who wants only to produce, and wants only to think. The theme of lust for Schopenhauer is thus to consider the horrors which will almost certainly follow the culmination of lust.

===St Thomas Aquinas===
St Thomas Aquinas defines the sin of lust in questions 153 and 154 of his ''[[Summa Theologica]]''. Aquinas says the sin of lust is of "voluptuous emotions", and makes the point that sexual pleasures, "unloosen the human spirit", and set aside right reason (p. 191). Aquinas restricts lust's subject matter to physical desires specifically arising from sexual acts, but he does not assume all sex-acts are sinful. Sex is not a sin in marriage, because sex is the only way for humans to reproduce. If sex is used naturally and the end purpose is reproduction there is no sin. Aquinas says, "if the end be good and if what is done is well-adapted to that, then no sin is present" (p. 193). However, sex simply for the sake of pleasure is lustful, and therefore a sin. A man who uses his body for lechery wrongs the Lord.

Sex may have the attributes of being sinless; however, when a person seeks sex for pleasure, he or she is sinning with lust. Lust is best defined by its specific attribute of rape, adultery, wet dreams, seduction, unnatural vice, and simple fornication.

[[Wet dreams]]: St Thomas Aquinas defined and discussed the topic of nocturnal emission, which occurs when one dreams of physical pleasure. Aquinas argues those who say that wet dreams are a sin and comparable to the actual experience of sex are wrong. Aquinas believes that such an action is sinless, for a dream is not under a person's control or free judgment. When one has a "nocturnal orgasm", it is not a sin, but it can lead to sins (p. 227). Aquinas says that wet dreams come from a physical cause of inappropriate pictures within your imagination, a psychological cause when thinking of sex while you fall asleep and a demonical cause whereby demons act upon the sleeper's body, "stirring the sleeper's imagination to bring about a orgasm" (p. 225). In the end, though, dreaming of lustful acts is not sinful. The "mind's awareness is less hindered", as the sleeper lacks right reason; therefore, a person cannot be accountable for what they dream while sleeping (p. 227).

[[Adultery]]: One of the main forms of lust seen frequently during the Middle Ages was the sin of adultery. The sin of adultery occurs when a person is unfaithful to his or her spouse, hence "invading of a bed not one's own" (p. 235). Adultery is a special kind of ugliness and many difficulties arise from it. When a man enters the bed of a married woman it not only is a sin, but it "wrongs the offspring", because the woman now calls into question the legitimacy of children (p. 235). If a wife has committed adultery before, then, her husband will question if all his wife's children are his offspring. 
	
[[Fornication|Simple fornication]]: Simple fornication is having sex with one's spouse for enjoyment rather than for bearing children. Fornication is also sex between two unmarried people, which is also a mortal sin. Aquinas says that "fornication is a deadly crime" (p. 213). Fornication is a mortal sin, but as Aquinas notes, "Pope Gregory treated sins of the flesh as less grievous than those of the spirit" (p. 217). Fornication was a grave sin such as that against property. Fornication, however, is not as grave as a sin directly against God and human life; therefore, murder is much worse than fornication. Property in this case means that a daughter is the property of her father, and if one does wrong to her, one then does wrong to him; therefore seducing a virgin or seeking pleasure from an unmarried woman is an invasion of a father's property.

[[Seduction]]: Seduction is a type of lust, because seduction is a sex act, which ravishes a virgin. Lust is a sin of sexual activity, and "...a special quality of wrong that appears if a maid still under her father's care is debauched" (p. 229). Seduction involves a discussion of property, as an unmarried girl is property of her father. A virgin, even though free from the bond of marriage, is not free from the bond of her family. When a virgin is violated without a promise of engagement, she is prevented from having honorable marriage, which is shameful to herself and her family. A man who performs sexual acts with a virgin must "endow her and have her to wife", and if the father, who is responsible for her, says no, then a man must pay a dowry to compensate for her loss of virginity and future chance of marriage (p. 229).

'''Unnatural vice:''' Unnatural vice is the worst kind of lust because it is unnatural in act and purpose. Many varieties of unnatural vice exist; Aquinas provides several examples, including [[bestiality]] or intercourse with a "thing of another species" (for example, an animal), incest, sodomy and "not observing the right manner of copulation".<ref>{{Cite web|url=https://ccel.org/ccel/aquinas/summa/summa.SS_Q154_A12.html|title = St. Thomas Aquinas: Summa Theologica - Christian Classics Ethereal Library}}</ref>
