Neither a purely negative nor a direct attack can ever suffice. There must be a coincidence of many silently oppugnant forces, emotional, scientific, and material. And, above all, there must be the slow steadfast growth of some replacing faith, which shall retain all the elements of moral beauty that once gave light to the old belief that has disappeared, and must still possess a living force in the new.
Here we find the good side of a religious reaction such as that which Rousseau led in the last century, and of which the Savoyard Vicar’s profession of faith was the famous symbol. Evil as this reaction was in many respects, and especially in the check which it gave to the application of positive methods and conceptions to the most important group of our beliefs, yet it had what was the very signal merit under the circumstances of the time, of keeping the religious emotions alive in association with a tolerant, pure, lofty, and living set of articles of faith, instead of feeding them on the dead superstitions which were at that moment the only practical alternative. The deism of Rousseau could not in any case have acquired the force of the corresponding religious reaction in England, because the former never acquired a compact and vigorous external organisation, as the latter did, especially in Wesleyanism and Evangelicalism, the most remarkable of its developments. In truth the vague, fluid, purely subjective character of deism disqualifies it from forming the doctrinal basis of any great objective and visible church, for it is at bottom the sublimation of individualism. But in itself it was a far less retrogressive, as well as a far less powerful, movement. It kept fewer of those dogmas which gradual change of intellectual climate had reduced to the condition of rank superstitions. It preserved some of its own, which a still further extension of the same change is assuredly destined to reduce to the same condition; but, nevertheless, along with them it cherished sentiments which the world will never willingly let die.
