ethnographers,[36] systematically makes reference. But howsoever evident this definition may appear, thanks to the mental habits which we owe to our religious education, there are many facts to which it is not applicable, but which appertain to the field of religion nevertheless. In the first place, there are great religions from which the idea of gods and spirits is absent, or at least, where it plays only a secondary and minor rôle. This is the case with Buddhism. Buddhism, says Burnouf, "sets itself in opposition to Brahmanism as a moral system without god and an atheism without Nature."[37] "As it recognizes not a god upon whom man depends," says Barth, "its doctrine is absolutely atheistic,"[38] while Oldenberg, in his turn, calls it "a faith without a god."[39] In fact, all that is essential to Buddhism is found in the four propositions which the faithful call the four noble truths.[40] The first states the existence of suffering as the accompaniment to the perpetual change of things; the second shows desire to be the cause of suffering; the third makes the suppression of desire the only means of suppressing sorrow; the fourth enumerates the three stages through which one must pass to attain this suppression: they are uprightness, meditation, and finally wisdom, the full possession of the doctrine. These three stages once traversed, one arrives at the end of the road, at the deliverance, at salvation by the Nirvâna. Now in none of these principles is there question of a divinity. The Buddhist is not interested in knowing whence came the world in which he lives and suffers; he takes it as a given fact,[41] and his whole concern is to escape it. On the other hand, in this work of salvation, he can count only upon himself; "he has no god to thank, as he had previously no god to invoke during his struggle."[42] Instead of praying, in the ordinary sense of the term, instead of turning towards a superior being and imploring his assistance, he relies upon himself and meditates. This is not saying "that he absolutely denies the existence of the beings called Indra, Agni and Varuna;[43] but he believes that he owes them nothing and that he has nothing to do with them," for their power can only extend over the goods of this world, which are without value for him. Then he is an atheist, in the sense that he does not concern himself with the question whether gods exist or not. Besides, even if they should exist, and with whatever powers they might be armed, the saint or the emancipated man regards himself superior to them; for that which causes the dignity of beings is not the extent of the action they exercise over things, but merely the degree of their advancement upon the road of salvation.[44]
