We must attack the enemy's line of communication. What we want is not more little books about Christianity, but more little books by Christians on other subjects—with their Christianity latent. You can see this most easily if you look at it the other way round. Our Faith is not very likely to be shaken by any book on Hinduism. But if whenever we read an elementary book on Geology, Botany, Politics, or Astronomy, we found that its implications were Hindu, that would shake us. It is not books written in direct defense of Materialism that make the modern man a materialist; it is the materialistic assumptions in all the other books. In the same way it is not books on Christianity that will really trouble him. But he would be troubled if, whenever he wanted a cheap popular introduction to some science, the best work on the market was always by a Christian.
The first step to the re-conversion of this country is a series, produced by Christians, which can beat the Penguin and the Thinkers Library on their own ground. Its Christianity would have to be latent, not explicit: and of course its science perfectly honest. Science twisted in the interests of apologetics would be sin and folly. But I must return to my immediate subject.
