The utilitarian principles behind religious practices have been taken for granted by many social scientists. In the Old Testament, for instance, shellfish and pork are prohibited; anthropologists have said that this is because shellfish can give hepatitis, and pork was an unusually filthy food back then; also, pigs required mud to cool off in in an area of limited water. Circumcision is still heralded as hygienic, making the circumcised boy less likely to get certain types of infections.
But there are tremendous holes in these arguments: many foods cause illness (salmonella on lettuce, for instance), and circumcision before antibiotics must have killed thousands, its health benefits so minuscule as to be negligible (although doctors continually press for it today, citing only these small benefits and never the negative, for the operation is a great financial perk.) Others may stick to their claims, however, and I am not going to nit pick over them - but merely to show, through the anthropologist's confessed feelings, that the functionalist arguments concerning religion are often wrongly placed. Sometimes, even often times, religious practices are not for the family or the individual. Instead, they are for the soul. That they might help individuals in some ways is often a side -effect or simply besides the point.
The treatment of the dead is a clear example. Throughout the world, there are prescriptions for the deceased intended to send them on to greater reward. To those who have seen the movie "Jeremiah Johnson" (so authentic in Indian ways that it's hard to believe it could be done), recall the fateful day Johnson took the white rescue party through the Indian funereal ground to save stranded pioneers. That breach caused him the death of his family and months or years of persecution by the tribe. However the practice may have helped tribal solidarity, it was clear that the violation of the spirits of the dead was foremost in mind - that their souls were being protected as they journeyed to the other world, and desecration jeopardized that journey.
It seems to me that in our rush to understand things, we often place them in the wrong box. The funeral service that the Professor went to was originally designed primarily for the soul, to aid it in its flight to heaven.
So I am reminded of this as I begin the preparations for my mother's funeral. Frankly, I want it all to go away. The initial shock is over and I don't want to return to it. I don't want a big ceremony or a wake where old friends and relatives come to give condolences (as nice as that is, and it really is). I want it over, to let the death sit and percolate in the subconscious as it always does, to later bring forth a truer sorrow and a greater meaning.
But it's not about me. If my brothers and sister and I were to think about it, we are not doing this for ourselves, and only partly for social convention. Behind it all, really, is an obligation to the deceased - that she deserves a proper send off. We are not worried about her place in the hereafter so much as the unspoken belief that she is still about somehow, waiting for us to show our appreciation for her life. And while the pragmatist may still claim that this is still about us and our feelings of obligation, in truth it is about our unspoken belief in the soul. It is waiting for its proper send off, no matter how much better or worse it makes us feel.
What the truth, the real Truth about death and the soul and time and place is, we have our inherited ideas, ideas that are deeper than any one culture or time. We understand that something survives after death and needs our attention. It is an obligation, and worth it, I suppose, just in case our hidden beliefs are true. But I also suppose it is about us, too - for we, whether we understand it or not, are hereby reminded that there is more to death than a void of darkness. That might be the true "practical" reason for many religious practices - to remind us that something else is there that is well beyond our nuts and bolts practical world. FK
