Briefly, it follows that the hope of a world-religion is an illusion, whether it be the dream of a perfect and world-wide Judaism, Buddhism, Christianity, or Mohammedanism. The sole authority in religious matters, that of the individual conscience, prevents any such consummation, which, even if it could be achieved, would be mischievous. The future will display a variety of beliefs and religions, as it does now. This need not discourage us, for therein is a sign of vitality or spiritual life, of which the world-religions are examples, marred, however, by their profession of universality, an ideal which they do not and never will realise. The notion of a Catholic Church or a great world- religion is really contrary to the duty of personal thought and reflection, which must inevitably (unless they give way to mere lazy repetition of other people’s thoughts) lead to differences. The tendency is for humanity to move away from dogmatic religion, with its pretensions to universality, catholicity, and monarchy (of which, says Guyau, the most curious type has just recently been achieved in our own day, by the Pope’s proclamation of the dogma of papal infallibility), towards religious individualism and to a plurality of religions. There may, of course, be religious associations or federations, but these will be free, and will not demand the adherence to any dogma as such. With the decay of dogmatic religion the best elements of religious life will have freer scope to develop themselves, and will grow both in intensity and in extent. “He alone is religious, in the philosophical sense of the word, who researches for, who thinks about, who loves, truth.” Such inquiry or search involves freedom, it involves conflict, but the conflict of ideas, which is perfectly compatible with toleration in a political sense, and is the essence of the spirit of the great world teachers. This is what Jesus foresaw when he remarked: “I did not come to bring peace, but a sword.” More fully, he might have put it, Guyau suggests: “I came not to bring peace into human thought, but an incessant battle of ideas; not repose, but movement and progress of spirit; not universal dogma, but liberty of belief, which is the first condition of growth.” Well might Renan remark that it was loyalty to such a spirit which caused him to break with the Church.
