I find the fruits of [Ezekiel Bulver's] discovery almost everywhere. Thus I see my religion dismissed on the grounds that ‘the comfortable parson had every reason for assuring the nineteenth century worker that poverty would be rewarded in another world’. Well, no doubt he had. On the assumption that Christianity is an error, I can see early enough that some people would still have a motive for inculcating it. I see it so easily that I can, of course, play the game the other way round, by saying that ‘the modern man has every reason for trying to convince himself that there are no eternal sanctions behind the morality he is rejecting’. For Bulverism is a truly democratic game in the sense that all can play it all day long, and that it gives no unfair privilege to the small and offensive minority who reason. But of course it gets us not one inch nearer to deciding whether, as a matter of fact, the Christian religion is true or false. That question remains to be discussed on quite different grounds — a matter of philosophical and historical argument. However it were decided, the improper motives of some people, both for believing it and for disbelieving it, would remain just as they are.
