This odd effect of the great agnostics in arousing doubts deeper than their own might be illustrated in many ways. I take only one. As I read and re-read all the non-Christian or anti-Christian accounts of the faith, from Huxley to Bradlaugh, a slow and awful impression grew gradually but graphically upon my mind--the impression that Christianity must be a most extraordinary thing. For not only (as I understood) had Christianity the most flaming vices, but it had apparently a mystical talent for combining vices which seemed inconsistent with each other. It was attacked on all sides and for all contradictory reasons. No sooner had one rationalist demonstrated that it was too far to the east than another demonstrated with equal clearness that it was much too far to the west. No sooner had my indignation died down at its angular and aggressive squareness than I was called up again to notice and condemn its enervating and sensual roundness. In case any reader has not come across the thing I mean, I will give such instances as I remember at random of this self-contradiction in the sceptical attack. I give four or five of them; there are fifty more. Thus, for instance, I was much moved by the eloquent attack on Christianity as a thing of inhuman gloom; for I thought (and still think) sincere pessimism the unpardonable sin. Insincere pessimism is a social accomplishment, rather agreeable than otherwise; and fortunately nearly all pessimism is insincere. But if Christianity was, as these people said, a thing purely pessimistic and opposed to life, then I was quite prepared to blow up St. Paul's Cathedral. But the extraordinary thing is this. They did prove to me in Chapter I. (to my complete satisfaction) that Christianity was too pessimistic; and then, in Chapter II., they began to prove to me that it was a great deal too optimistic. One accusation against Christianity was that it prevented men, by morbid tears and terrors, from seeking joy and liberty in the bosom of Nature. But another accusation was that it comforted men with a fictitious providence, and put them in a pink-and-white nursery. One great agnostic asked why Nature was not beautiful enough, and why it was hard to be free. Another great agnostic objected that Christian optimism, "the garment of make-believe woven by pious hands," hid from us the fact that Nature was ugly, and that it was impossible to be free. One rationalist had hardly done calling Christianity a nightmare before another began to call it a fool's paradise. This puzzled me; the charges seemed inconsistent. Christianity could not at once be the black mask on a white world, and also the white mask on a black world. The state of the Christian could not be at once so comfortable that he was a coward to cling to it, and so uncomfortable that he was a fool to stand it. If it falsified human vision it must falsify it one way or another; it could not wear both green and rose-coloured spectacles.
