In the latest issue of New Scientist , Michael Brooks tries to explain religious belief away with evolutionary theory:
While many institutions collapsed during the Great Depression that began in 1929, one kind did rather well. During this leanest of times, the strictest, most authoritarian churches saw a surge in attendance.
This anomaly was documented in the early 1970s, but only now is science beginning to tell us why. It turns out that human beings have a natural inclination for religious belief, especially during hard times. Our brains effortlessly conjure up an imaginary world of spirits, gods and monsters, and the more insecure we feel, the harder it is to resist the pull of this supernatural world. It seems that our minds are finely tuned to believe in gods . . . .
The origin of religious belief is something of a mystery, but in recent years scientists have started to make suggestions. One leading idea is that religion is an evolutionary adaptation that makes people more likely to survive and pass their genes onto the next generation. In this view, shared religious belief helped our ancestors form tightly knit groups that cooperated in hunting, foraging and childcare, enabling these groups to outcompete others. In this way, the theory goes, religion was selected for by evolution, and eventually permeated every human society.
To which Chesterton replied , more than eighty years earlier:
It is commonly affirmed, again, that religion grew in a very slow and evolutionary manner; and even that it grew not from one cause; but from a combination that might be called a coincidence. Generally speaking, the three chief elements in the combination are, first, the fear of the chief of the tribe, . . . second, the phenomena of dreams, and third, the sacrificial associations of the harvest and the resurrection symbolised in the growing corn. I may remark in passing that it seems to me very doubtful psychology to refer one living and single spirit to three dead and disconnected causes, if they were merely dead and disconnected causes. Suppose Mr. Wells, in one of his fascinating novels of the future, were to tell us that there would arise among men a new and as yet nameless passion, of which men will dream as they dream of first love, for which they will die as they die for a flag and a fatherland. I think we should be a little puzzled if he told us that this singular sentiment would be a combination of the habit of smoking Woodbines, the increase of the income tax and the pleasure of a motorist in exceeding the speed limit. We could not easily imagine this, because we could not imagine any connection between the three or any common feeling that could include them all. Nor could anyone imagine any connection between corn and dreams and an old chief with a spear, unless there was already a common feeling to include them all. But if there was such a common feeling it could only be the religious feeling; and these things could not be the beginnings of a religious feeling that existed already. I think anybody’s common sense will tell him that it is far more likely that this sort of mystical sentiment did exist already; and that in the light of it dreams and kings and corn-fields could appear mystical then, as they can appear mystical now.
