Continuing my series on the evolutionary morality of the 7 Deadly Sins. 4/7 of the way there… perhaps by 2011 we’ll be finished.
Popularly termed “every man’s battle,” lust is probably the most oft confessed sin by men everywhere. It’s common. It’s hardwired into men as a gender. The desire for sex is biological, the reward both psychological and neurochemical. Beyond this, it is the drive of all genetically reproducing organisms to “sow their seed” as one might say. Why is it wrong? Why deny such a basic instinct? I believe it is the first instance where what is deemed beneficial to the species (greater population) is deemed immoral and wrong for the individual.
What we understand as lust is very different from the world our ancestors grew up in. With prostitution being termed the “oldest trade”, men (or women) could satisfy their sexual desires. Later developments were sexual displays and theater. However, even these do not compare to the world in which we define lust today. Multiple factors exponentially increase the opportunity for lust. The internet is by far the greatest revolution in distribution. The ability for anyone to produce and distribute photography, print media, and video recordings as meta-products (those which go beyond the tangible product by not necessitating physical hard copies for consumption) greatly expands the sheer volume of published material. Beyond simply a lust of the eyes, advancements in contraception has made it simpler to indulge in the lust of the flesh with less probability of impregnation and, thus, less chance of financial and relational liability to actions. With all of these advancements, it is no wonder that one sees such a rampant industry and why men find it such a difficult “battle” to fight. (That is, if their moral conviction leads them to avoiding lustful indulgence.)
Why, if it’s so wrong, is it so natural? Evolutionary psychology bases itself upon the principle that the neuroanatomy of an organism is what dictates its psychology. However, the neuroanatomy of the organism is dictated by the genetics of the organism. These are then held to the same genetic principles of other traits: the ones that help you survive and procreate are, thus, the ones most likely to be passed on and become most populous in a species. If a gene codes for heightened sexual desire in neuroanatomy, it seems likely that this gene will be passed on. It dictates a greater chance for its survival by increasing the likelihood its possessor will have sex. The stronger the encoded desire becomes, the better chance it has of continued survival and spread. So, as you can see, the chances of a gene for sexual desire continuing to spread and mutate toward stronger desire is obvious. Especially in the male of the species who has more seeds to sow. For the female, her gametes (eggs) are limited to a precious few, and if one is successfully impregnated, she is then taken “off the sexual market” due to the incapability of her to become pregnant again for the next 9 months. In this explanation, I hope you might also see how infidelity can become the strong temptation for the male. If the drive tells him to have as many offspring as possible, it seems a more feasible goal if one has as many mates as possible. (Interestingly, women are more forgiving of men for having extra-relational intercourse than men are of women. Another example of evolutionary psychology, in that a male values the loyalty of his partner to spreading his genes as opposed to a woman valuing the care and emotional satisfaction of the relationship.)
None of this is an excuse for infidelity or all-consuming lust by men everywhere. It simply is a reason for why those desires exist. We are not completely controlled by our psychological/biological desires. If you can skip a meal, you can skip some extraneous sex.
So why is it wrong? In many cases, as with gluttony and laziness, it is over-indulgence in the flesh that causes the religious institution to find it wrong. It is against the idea that the actions of the body do not affect the soul, and, strays toward the ascetic approach to maintain purity; that is, that the flesh is evil and indulgence in its desires are, thus, evil. However, does this run deeper? There has been a social impact of all previously addressed sins, is there one here?
In the modern era, one could make an argument that, provided it remains a private indulgence, consuming pornography has no impact on social life whatsoever. The problem with consuming pornography is its degradation of the humanity of those depicted. If it is not right to publicly oggle another human being, is it right to do it privately? One might argue that these women are degrading themselves by posing for the photo initially, and this may be true, but, just because there is a product provided does not mean consumption of it is ethical. Is it right to think racist thoughts regarding another human being as long as you’re cordial in your interaction? Or do we see a problem there? It’s a matter of equality.
We are a functionally monogamous species. The amount of sex that takes place outside monogamous relationships (and the number of monogamous relationships that an individual might have in their lifetime) shows that this is not our natural state. One of our close genetic relatives, the gorilla displays more primitive sexual behaviors. There is a tendency for a patriarchal society in a group of gorillas with one male designated as the leader (typically the “silverback”, denoted by the gray hair covering its back) and the females mating nearly exclusively with him. In a similar manner, in the more primitive societies of human culture, polygamy is a relative norm. Why do more “advanced” civilizations have these monogamous stipulations? My hypothesis is that it relates to equality, respect, and rights. While women have not had the same rights as men for what could be considered a “long time” respective to the existence of “advanced” civilizations, in some sense, I believe this shows some tier of rights that they might have possessed. The idea of female equality is not necessarily new. It is one that has been wrestled with by many civilizations over history. I would submit, if a female is perceived as “less” than you, it is easier to feel justified in your perception of her in a lustful manner. It is not then degradation, it is acknowledgment of truth. Over time, I believe history has progressed toward a generally accepted equality of both genders.
The question still remains, is there social consequence to lust? Obviously, there is an element of social consequence to the action of unwanted public degradation. However, the private action does denote a power element. Rather than work to gain the right for a sexual relationship, one simply finds another outlet for the biological need. In any form, this is not consensual or equal. One party either receives payment for deeds or simply has their image used for sexual stimuli. One might argue that it is better done to an image or a person who gets some sort of recompense for the action, but in the culturally progressive view of equality, respect, and rights it is, rightfully, taboo. This, I believe, is why it is unstated and viewed as a “skeleton in the closet.”
