Look at it how we will, even were religion unfounded our life would on the whole gain in fulness far more than it would lose, by our believing in religion. Hence some of our more thoughtful agnostics, however unable themselves to find support in what they deem an illusion, are quite willing to acknowledge the part religion has played in the past in the evolution of rational life, and to look upon it as a necessary factor in the earlier stages of that process whose place is to be taken hereafter by some as yet undefined substitute. If indeed Nature thus works by illusions and justifies the lying means by the benevolent end, it is hard to believe in a moral government of the universe, or to hope that an "absolute morality"--righteousness for its own sake--will be the outcome of such disreputable methods. But till the illusion of "absolute morality" is strong enough to take care of itself, and has passed from the professors to the populace, it is plainly for the interest and happiness of individuals and of society to hold fast to religion. Undoubtedly then the advantages resulting from a belief in religion, whether valid or illusory, are such as to incline not only the higher and more unselfish minds, but even those which are more prudential and self-regarding, to wish to hold that belief--to be unwilling to hear arguments against it. But among the former class will be found many intellectually conscientious and even scrupulous persons, whom the recognition of this inevitable bias will drive to an extreme of caution. Not so much because the facts believed-in are of such intense moment, but rather because the belief itself, whether true or false, is so consoling and helpful, that there seems to them a danger of self-deception just proportioned to their wish to believe. It were then no small rest and relief to such, could it be shown that what they deem a reason for doubt, is really a reason for belief; that the welcome which all that is best in them gives to a belief, affords some sort of philosophical justification thereof. This particular argument had undoubtedly a more favourable hearing in the age of Chateaubriand, when unbelief stopped short at the threshold of what was called "Natural Religion," and the apologist's task was confined to the establishment of revelation. "It is now pretty generally admitted," says the author of _Contemporary Evolution_, "with regard to Christianity and theism that the arguments really telling against the first, are in their logical consequences fatal also to the second, and that a _Deus Unus, Remunerator_ once admitted, an antecedent probability for a revelation must be conceded."
