Such is the famous _Law of the three States_, which has always been treated by friend and foe as the key to the Comtean philosophy. It only concerns us now to describe the use he made of it in abolishing the belief in God, and thus attempting to revolutionise the conception of religion. Closely associated with his Law of the three States is another which he calls the _Law of the Wills and Causes_. In fact, there is practically no difference between that law and the first or theological stage through which human knowledge goes. It may be enunciated thus: Whenever the human mind is in ignorance of the proximate causes of a given phenomenon, it tends to ascribe it to the agency of superior and invisible powers. Hence, ignorance of nature, which modern science has largely remedied, led men to ascribe to "the act of God" innumerable events, even the appearance of Halley's comet, which we now unhesitatingly refer to subordinate agencies. Why, then, urged Comte, should we continue to believe in even one supreme Cause, when we may hope, with the advance of science, to give an explanation of every natural occurrence or fact? Convinced on social grounds that belief in the Deity had been of no service to mankind, he sought for philosophical reasons to justify his surrendering the tenet, and thus formulated the famous law which has just been enunciated. If that law is valid and universal in its application, we should have to surrender all hope of Comte's co-operation with what we hold to be rational religion. But it is because I am so convinced that it is that very law, so finely framed and stated by Comte, which makes it impossible to dispense with belief in a supra-mundane Power, that I adhere to the ideal which I sketched in the beginning, that Kant and Comte will be found to be, after Christ, the master builders of the second temple which is to be the religious home of the ages to come.
