You can do a search on my name and Harris to see my numerous past debunkings of his claims.
In essence Harris claims that the pig was made taboo because it fouled and/or used a lot of water and competed with humans for food, and thus banning the keeping of pigs was a sound startegy that allowed te Abrahamic faiths to outcompete other cultures.
The biggest problem with that to my mind is one that Diogenes already adressed: that for most of history less than 1% of Semitic people and less than 50% of the population of Palestine had a taboo against pigs. That by itself falsifies Harris’ theory. Quite clearly peoples with taboos against pigs didn’t outcompete those without whether in the NA/ME region generally or Palestine/Judea specifically. The one objectively testable prediction that Harris makes actauly contradicts his own hypothesis. People who keep pigs provably performed better in that environment than those who didn’t.
But Harris ignoire that and instead concentrates on the fact that Moslems eventually came to dominate the region, several thousand years after the taboo against keeping pigs was introduced. IOW he is engaging in an “after this therefore because of this” fallacy.
On the more theoretical side the problem is that while it is true that pigs can foul water, they are much less likely to do so than cattle or camels whcih are notorious for fouling water. More importantly surface water in the middle east was all so fouled by human waste anyway that it is up to Harris to provide any evidence at all that pigs woudl have made any difference. He fails to present any evidence to this effect.
His claim that pigs compete with humans for food is farcical from beginning to end. If pigs were a net food loss then humans wouldn’t keep them. It’s that simple. In fact what pigs do is utilise food sources that humans can’t utilise, and turn it into a food source that we can. Without pigs, Abrahamic societies have no way of utilising food such as carrion, wild tubers and acorns, pine nuts and other wild fruit. Pigs fulfil that role in societies that keep them, and are provide a massive boost to communal protein intake for that very reason. In return pigs need to be supplemented with table wastes or other foods so they don’t wander away from the village. So, far from competing with humans for food, pigs are a major food source for humans that keep them. Harris’ claim that pigs are socially damaging because only rich people eat pigs and so they effectively take food from the poor is simply balderdash for which he offers not a shred of support.
Then we get to the point that chickens and pigeons are kosher animals that were and are kept by Abrahamic peoples, and yet these animals do directly compete with humans for food and are enet calorie loss. Pigs are are self sufficient in terms of food and only need supplemental reward feeding to keep them domesticated. In contrast chickens and doves in a Mediterranean village environment obtain only a tiny portion of their food from foraging and are dependant entirley on human feeding for their survival. Stop feeding them and they starve to death in short order or abandon the village. So chickens and doves are genuine competitors with humans for food, yet are perfectly acceptable Halal/Kosher food.
Yet according to Harris any society that keeps anaimals that comepete with humans for food is at a massive survival disadvanatge. Of course this is just another crock for which Harris presents no evidence and which contradicts the known facts. There is a good reason why the chicken has been so widely domesticated depite being a net food sink. Like pigs, chickens are capable of turning foods humans can’t utilise into high quality food. Given low protein, carbohydrate rich food such as whole grain or potatoes, chickens will turn vermin such as cockroaches and mice into high quality protein. More importantly they do so in neat daily packets. That means that a person with a chicken never suffers severe protein deficiency provided that he harvests enough grain to feed the chicken. That’s a massive advantage in peasant societies where carbohydrate is abundant and protein limiting.
But Harris overlooks this important point, indeed he glosses over the whole issue of chickens and doves in a couple of paragraphs. Pigs don’t compete with humans for food but even if they did, as chickens and doves do, they still wouldn’t be a liability because they represent a net source of protein due to the ability to turn food such as wild fruits, vermin and carrion into human utilisable protein. That is why humans keep chickens and doves despite the fact that they compete with humans for food.
The most comical of Harris’ outpourings is when he suggests that camels and horses are far to important for transport to be eaten. Yet the Roman era ME horse and camel heard were probably a few tens of thousands of animals. In contrast the herds of kosher animals was in the millions. How could making camels and horses kosher possibly result in a reduction in the number of animals raised, as Harris claims? Once again Harris makes the claim as a way of glossing over inconvenient facts. He never explains or presents and evidence as to why camels would be less common if they could be eaten as well as ridden when common sense and basic economics says that diversifying the market for a commmodity will cause an increase in production.
He also completely ignores that fact that, if camels and horses were able to be eaten, then people wouldn’t be obliged to slaughter old horses and camles and then waste wood burning the carcasses. This is very important considering that Harris’ whole thesis is based on an evolutionary argument that food is at a premiuim and the prinmary survival mechanism in these societies. Yet the very laws he discusses obliges people to abandon a perfectly good food source such as an old horse and waste energy disposing of the carcasse rather than eating it.
Harris also largely glosses over the fact that Jews and Moslens aren’t forbidden from eating pigs. They are forbidden from eating any mammal that isn’t a cervid or bovid. That means they can’t eat most of the eild game of the ME either. For a law that Harris’s thesis requires is widespread because it make more food avaialble it is incredible that he ignores the fact that it actually reduces the amount of food available.
I get the strong impression that Harris desperately wants to find some logical reason for Jewish dietary laws, whether for personal religious reasons or to sell to a religious audience. Unfortunately he will happily ignore contradictory evidence in order to invent such reasons. His ideas are are largely unscientific, and the few that do approach science don’t stand up to even the most basic scrutiny and require a strict policy of ignoring inconvenient evidence to be remain coherent.
