Yet the belief in Humanity, while stimulating Sympathy, at the same time enlarges the scope and vigour of the Intellect. For it requires high powers of generalization to conceive clearly of this vast organism, as the result of spontaneous co-operation, abstraction made of all partial antagonisms. Reason, then, has its part in this central dogma as well as Love. It enlarges and completes our conception of the Supreme Being, by revealing to us the external and internal conditions of its existence. Lastly, our active powers are stimulated by it no less than our feelings and our reason. For since Humanity is so far more complex than any other organism, it will react more strongly and more continuously on its environment, submitting to its influence and so modifying it. Hence results Progress which is simply the development of Order, under the influence of Love. Thus, in the conception of Humanity, the three essential aspects of Positivism, its subjective principle, its objective dogma, and its practical object, are united. Towards Humanity, who is for us the only true Great Being, we, the conscious elements of whom she is composed, shall henceforth direct every aspect of our life, individual or collective. Our thoughts will be devoted to the knowledge of Humanity, our affections to her love, our actions to her service. Positivists then may, more truly than theological believers of whatever creed, regard life as a continuous and earnest act of worship; worship which will elevate and purify our feelings, enlarge and enlighten our thoughts, ennoble and invigorate our actions. It supplies a direct solution, so far as a solution is possible, of the great problem of the Middle Ages, the subordination of Politics to Morals. For this follows at once from the consecration now given to the principle that social sympathy should preponderate over self-love. Thus Positivism becomes, in the true sense of the word, a Religion; the only religion which is real and complete; destined therefore to replace all imperfect and provisional systems resting on the primitive basis of theology.
