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.
