What is striking about the books which were written, especially during the eighteenth century, to defend Christianity against these attacks, is the degree to which they accept the assumptions of their assailants. Christianity is defended as being reasonable. It can be accommodated within these assumptions, which all reasonable people hold. There is little suggestion that the assumptions themselves are to be challenged. The defense is, in fact, a tactical retreat. But, as later history has shown, these tactical retreats can--if repeated often enough--begin to look more like a rout.
