Now, to the plain man it will always seem that if our very notion of causality is derived from our own volition—as our very notion of energy is derived from our sense of effort in overcoming resistance by our volition—presumably the truest notion we can form of that in which causation objectively consists is the notion derived from that known mode of existence which alone gives us the notion of causality at all. Hence the plain man will always infer that all energy is of the nature of will-energy, and all objective causation of the nature of subjective. Nor is this inference confined to the plain man; the deepest philosophical thinkers have arrived at substantially the same opinion, e.g. Hegel, Schopenhauer. So that the direct and most natural interpretation of causality in external nature which is drawn by primitive thought in savages and young children, seems destined to become also the ultimate deliverance of human thought in the highest levels of its culture[48].

But, be this as it may, we are not concerned with any such questions of abstract philosophical speculation. As pure agnostics they lie beyond our sphere. Therefore, I allude to them only for the sake of showing that there is nothing either in the science or philosophy of mankind inimical to the theory of natural causation being the energizing of a will objective to us. And we can plainly see that if such be the case, and if that will be self-consistent, its operations, as revealed in natural causation, must appear to us when considered en bloc (or not piece-meal as by savages), non-volitional, or mechanical.

Of all philosophical theories of causality the most repugnant to reason must be those of Hume, Kant and Mill, which while differing from one another agree in this—that they attribute the principle of causality to a creation of our own minds, or in other words deny that there is anything objective in the relation of cause and effect—i.e. in the very thing which all physical science is engaged in discovering in particular cases of it.

The conflict of Science and Religion has always arisen from one common ground of agreement, or fundamental postulate of both parties—without which, indeed, it would plainly have been impossible that any conflict could have arisen, inasmuch as there would then have been no field for battle. Every thesis must rest on some hypothesis; therefore, in cases where two or more rival theses rest on a common hypothesis, the disputes must needs collapse so soon as the common hypothesis is proved erroneous. And proportionably, in whatever degree the previously common hypothesis is shown to be dubious, in that degree are the disputations shown to be possibly unreal. Now, it is one of the main objects of this treatise to show that the common hypothesis on which all the disputes between Science and Religion have arisen, is highly dubious. And not only so, but that quite apart from modern science all the difficulties on the side of intellect (or reason) which religious belief has ever encountered in the past, or can ever encounter in the future, whether in the individual or the race, arise, and arise exclusively, from the self-same ground of this highly dubious hypothesis.

The hypothesis, or fundamental postulate, in question is, If there be a personal God, He is not immediately concerned with natural causation. It is assumed that qua 'first cause,' He can in no way be concerned with 'second causes,' further than by having started them in the first instance as a great machinery of 'natural causation,' working under 'general laws.' True the theory of Deism, which entertains more or less expressly this hypothesis of 'Deus ex machina,' has during the present century been more and more superseded by that of Theism, which entertains also in some indefinable measure the doctrine of 'immanence'; as well as by that of Pantheism, which expressly holds this doctrine to the exclusion in toto of its rival. But Theism has never yet entertained it sufficiently or up to the degree required by the pure logic of the case, while Pantheism has but rarely considered the rival doctrine of personality—or the possible union of immanence with personality.[49]

Now it is the object of this book to go much further than any one has hitherto gone in proving the possibility of this union. For I purpose to show that, provided only we lay aside all prejudice, sentiment, &c., and follow to its logical termination the guidance of pure reason, there are no other conclusions to be reached than these. Namely, (A) That if there be a personal God, no reason can be assigned why He should not be immanent in nature, or why all causation should not be the immediate expression of His will. (B) That every available reason points to the inference that He probably is so. (C) That if He is so, and if His will is self-consistent, all natural causation must needs appear to us 'mechanical.' Therefore (D) that it is no argument against the divine origin of a thing, event, &c., to prove it due to natural causation.

After having dealt briefly with (A), (B) and (C), I would show that (D) is the most practically important of these four conclusions. For the fundamental hypothesis which I began by mentioning is just the opposite of this. Whether tacitly or expressly, it has always been assumed by both sides in the controversy between Science and Religion, that as soon as this that and the other phenomenon has been explained by means of natural causation, it has thereupon ceased to be ascribable [directly] to God. The distinction between the natural and the supernatural has always been regarded by both sides as indisputably sound, and this fundamental agreement as to ground of battle has furnished the only possible condition to fighting. It has also furnished the condition of all the past, and may possibly furnish the condition of all the future, discomfitures of religion. True religion is indeed learning her lesson that something is wrong in her method of fighting, and many of her soldiers are now waking up to the fact that it is here that her error lies—as in past times they woke up to see the error of denying the movement of the earth, the antiquity of the earth, the origin of species by evolution, &c. But no one, even of her captains and generals, has so far followed up their advantage to its ultimate consequences. And this is what I want to do. The logical advantage is clearly on their side; and it is their own fault if they do not gain the ultimate victory,—not only as against science, but as against intellectual dogmatism in every form. This can be routed all along the line. For science is only the organized study of natural causation, and the experience of every human being, in so far as it leads to dogmatism on purely intellectual grounds, does so on account of entertaining the fundamental postulate in question. The influence of custom and want of imagination is here very great. But the answer always should be to move the ulterior question—what is the nature of natural causation?

Now I propose to push to its full logical conclusion the consequence of this answer. For no one, even the most orthodox, has as yet learnt this lesson of religion to anything like fullness. God is still grudged His own universe, so to speak, as far and as often as He can possibly be. As examples we may take the natural growth of Christianity out of previous religions; the natural spread of it; the natural conversion of St. Paul, or of anybody else. It is still assumed on both sides that there must be something inexplicable or miraculous about a phenomenon in order to its being divine.

What else have science and religion ever had to fight about save on the basis of this common hypothesis, and hence as to whether the causation of such and such a phenomenon has been 'natural' or 'super-natural.' For even the disputes as to science contradicting scripture, ultimately turn on the assumption of inspiration (supposing it genuine) being 'super-natural' as to its causation. Once grant that it is 'natural' and all possible ground of dispute is removed.

I can well understand why infidelity should make the basal assumption in question, because its whole case must rest thereon. But surely it is time for theists to abandon this assumption.
