I've mentioned a few clear objective arguments in this thread, and in a thread titled "Animal cruelty".
Hopefully, I will have time today and tomorrow to visit those points, but anytime "cruelty" or "morality" are involved in discussions of meat and vegetables, as such, I refer to Aldous Huxley. Were our eyes considerably keener than they are, we would openly perceive the suffocating gasps, the dying throes of the plants. Huxley speculates that to have witnessed even the laboratory representations he saw at the Bose Institute in 1925, one proclaiming the moral basis of vegetarianism would have reason to reconsider.
But as to the evolution of the species, I agree that the species will evolve regardless of what we do. However, what is the basis for "choosing" an evolutionary course?
Would we be happy on a flavored microbial diet? Vast farms for breeding microorganisms either for direct consumption or for the culinary treats of their waste? After all, given Huxley's outlook and humanity's tendency toward the extremeties of progress, why stop at the cruelty shown animals?
To take an indirect comparison: Would it be better, then, to suppress the damage and cruelty inherent in the human-societal sexual experience and limit reproduction to the laboratory since we are capable of fertilizing under glass? Why not engineer Bokanovsky sets
a la Huxley? We might consider that sex has a number of other "uses" deemed legitimate among its participants. Face it, for most humans, sex feels good, just like, to borrow a phrase, "pork chops are good".
So what do we do, then, when faced with the assertion that eating, and not sex, is the most sensual experience known to human existence? There is a satisfaction greater than the post-orgasmic that comes from a peppercorn New York steak at El Gaucho, or the pepper sauce Delmonico at the Met.
I should no more go celibate merely to abate the moral crises surrounding the importance of sex than I should give up meat in order to abate the moral thunder of the gathered vegetarian masses offended by my unwillingness to imitate them. That I don't eat eggs has nothing to do with my morals; I simply don't like eggs. But although I am aware of the problems in harvesting other animal products (e.g dairy) for consumption, I will give up breathing on a moral basis long before I give up alfredo.
Are the personal, intangible rewards of interpersonal behaviors (e.g. sex/love) any more or less real than the internal and intangible rewards of what we eat? There is a post-dining phrase many stoners are familiar with:
Fat, dumb, and happy. And yes, there is tremendous value in that degree of satisfaction that
anyone can get from the food they eat. The culinary arts could take a flying leap for all I care except that there are certain empirical benefits. Take away the satisfaction one gets even from a steaming bowl of Hamburger Helper and you might as well take away music, while you're at it. People will react, whether they choose to or not.
So not only would we be choosing to restructure our evolutionary diet on the basis of morals, we would also reshape our evolutionary psychology for no better reason. In a world so without reward, so devoid of love, can humanity really thrive?
Perhaps. If we choose to evolve in such a dispassionate, conscious manner.
(The "starving children in India" argument never really worked for me, so I can't see how, "I know the food sucks, Timmy, but eat up: it's for the benefit of the species," will work any better.)
Someone ought to take the anti-meat argument to groups like MorningStar; after all, what's the point of making food that imitates meat if they're only imitating immorality? Seriously: "You don't need meat; try this textured vegetable protein that's made to look and smell and, allegedly, taste just like chicken!" Of course, what would we call the fake "buffalo wings"?
To restate with certain accent: "Is there any one clear objective argument against the consuming of meat
sufficient to justify converting the entire human species to a vegetarian diet? Is there a moral argument
sufficient to justify that we should determine to evolve the species in such a fundamental way?"
Yes, we make moral determinations affecting evolution, but what a species eats is very, very fundamental.
