The idea that secularists have few or no children, that the religious have lots of children, and that this will lead to a lessening of the influence of secularism, had occurred to me from time to time, especially with regard to Europe. I am grateful to Eric Kaufmann for clothing this idea with facts and figures, and producing a very thought-provoking, as well as readable, book. The author's assertions and conclusions, especially in his last chapter, will give rise to dispute, but they cannot be ignored.
The question in the title, "Shall the religious inherit the earth?", is answered in the book's final sentence: "The religious shall inherit the earth."
I tried to figure out the author's personal religious viewpoint, and I came to feel that he believes in the possibility of a God of some sort; but he is basically a secularist, with the standard secularist outlook on such things as abortion and gay rights, and even global warming. This means that he cannot be accused of promoting a piece of religious propaganda - in fact, he seems distressed by his conclusions.
His principal focus is on three areas: the religious right in the US, fundamentalist Islam, and ultra-orthodox Judaism. This last area is particularly fascinating and contains much that those outside the Jewish world will be unfamiliar with.
There is surprisingly little mention of Catholicism, and in fact he seems to make an error regarding the Catholic Church. On page 23 he says, referring to Vatican II, that it "helped bring Church policy on contraception and birth control into line with the liberal practice of many modern Catholics...". This is completely wrong. Has he never heard of Paul VI's encyclical Humanae vitae, which caused such an uproar?
He mentions (page 94) the American patriarchal movement, Quiverfull, and quoting the work of the journalist Kathryn Joyce, says that Quiverfull rejects even the rhythm method of birth control. But does anyone still use the rhythm method? As I understand, the Billings method has long ago overtaken the rhythm method as a far more reliable technique of natural birth control.
Secularists ought to read the book to gain some idea of what may be coming. If they are older they will not live to see it come to fruition, but if they are younger, they very well may. Nevertheless, it is worth bearing in mind that history contains many sudden and unforeseen changes in direction.
