Rationalistic Spiritualism admits the reality of Psychology, of Ontology, and of Theology, just as it does that of Physiology; it admits that these different sciences owe their birth and development necessarily to the spectacle of the universe, of men and of things, and have for their object the solution of the questions which this spectacle suggests. But this great fact once admitted, Rationalism places in Psychology, and in Psychology alone, the starting-point and the fulcrum of Ontology and of Theology; it only admits in these two sciences results to which the human mind attains by its own unaided efforts, that is to say, by way of observation and of reasoning; it recognises for human knowledge, with respect to Ontology and Theology, no source other than human reason. {133} Christianity opens to Ontology and Theology a larger sphere and other sources of knowledge: besides the psychological facts supplied to these two sciences by observation and reasoning, it recognises historical facts as truths, not only which they are bound themselves to admit, but which they have a right to demand that others shall admit; Christianity does not make the human mind the sole object of its belief; it believes also in the history of Humanity, and finds in that History facts to the truth of which centuries, and the traditions of centuries, have testified, which it therefore holds, and is bound to hold, as well proved and as certain as any physical or psychological fact proved by the observations of contemporary science. The Creation, the primitive Revelation, the Mosaic Revelation, the Evangelical Revelation, are in Christian Doctrine historical facts which Ontology and Theology take, with reason, as the elementary data and the legitimate bases of science. {134} I am here met by a fundamental objection made to these facts and to their scientific authority; they are, it is said, opposed to the permanent laws of nature and of reason, as well as of human experience; science cannot admit supernatural facts. I have no intention in merely passing to re-enter here upon this great question; I have already expressed unreservedly my opinion with respect to it, [Footnote 37] and upon some other occasion I shall return to it; for, if I do not deceive myself, the question has not hitherto been properly sounded and to the depth which it demands. Here I confine myself to referring to two ideas--facts, rather--absolutely forgotten or ignored by the systematic opponents of the supernatural.
