In regard to Mind as it makes itself felt in the world, the questions which Cosmology chiefly discussed turned upon the freedom of man and the origin of evil. Nobody can deny that these are questions of the highest importance. But to give them a satisfactory answer, it is above all things necessary not to claim finality for the abstract formulae of understanding, or to suppose that each of the two terms in an antithesis has an independent-subsistence or can be treated in its isolation as a complete and self-centred truth. This however is the general position taken by the metaphysicians before Kant, and appears in their cosmological discussions, which for that reason were incapable of compassing their purpose, to understand the phenomena of the world. Observe how they proceed with the distinction between freedom and necessity, in their application of these categories to Nature and Mind. Nature they regard as subject in its workings to necessity; Mind they hold to be free. No doubt there is a real foundation for this distinction in the very core of the Mind itself: but freedom and necessity, when thus abstractly opposed, are terms applicable only in the finite world to which, as such, they belong. A freedom involving no necessity, and mere necessity without freedom, are abstract and in this way untrue formulae of [thought. Freedom is no blank indeterminateness: essentially concrete, and unvaryingly self-determinate, it is so far at the same time necessary. Necessity, again, in the ordinary acceptation of the term in popular philosophy, means determination from without only,—as in finite mechanics, where a body moves only when it is struck by another body, and moves in the direction communicated to it by the impact.—This however is a merely external necessity, not the real inward necessity which is identical with freedom.
The case is similar with the contrast of Good and Evil,—the favourite contrast of the introspective modern world. If we regard Evil as possessing a fixity of its own, apart and distinct from Good, we are to a certain extent right: there is an opposition between them: nor do those who maintain the apparent and relative character of the opposition mean that Evil and Good in the Absolute are one, or, in accordance with the modern phrase, that a thing first becomes evil from our way of looking at it. The error arises when we take Evil as a permanent positive, instead of—what it really is—a negative which, though it would fain assert itself, has no real persistence, and is, in fact, only the absolute sham-existence of negativity in itself.
36.] The fourth branch of metaphysics is Natural or Rational Theology. The notion of God, or God as a possible being, the proofs of his existence, and his properties, formed the study of this branch.
(a) When understanding thus discusses the Deity, its main purpose is to find what predicates correspond or not to the fact we have in our imagination as God. And in so doing it assumes the contrast between positive and negative to be absolute; and hence, in the long run, nothing is left for the notion as understanding takes it, but the empty abstraction of indeterminate Being, of mere reality or positivity, the lifeless product of modern 'Deism.'
(b) The method of demonstration employed in finite knowledge must always lead to an inversion of the true order. For it requires the statement of some objective ground for God's being, which thus acquires the appearance of being derived from something else. This mode of proof, guided as it is by the canon of mere analytical identity, is embarrassed by the difficulty of passing from the finite to the infinite. Either the finitude of the existing world, which is left as much a fact as it was before, clings to the notion of Deity, and God has to be defined as the immediate substance of that world,—which is Pantheism: or He remains an object set over against the subject, and in this way, finite,—which is Dualism.
(c) The attributes of God which ought to be various and precise, had, properly speaking, sunk and disappeared in the abstract notion of pure reality, of indeterminate Being. Yet in our material thought, the finite world continues, meanwhile, to have a real being, with God as a sort of antithesis: and thus arises the further picture of different relations of God to the world. These, formulated as properties, must, on the one hand, as relations to finite circumstances, themselves possess a finite character (giving us such properties as just, gracious, mighty, wise, &c.); on the other hand they must be infinite. Now on this level of thought the only means, and a hazy one, of reconciling these opposing requirements was quantitative exaltation of the properties, forcing them into indeterminateness,—into the sensus eminentior. But it was an expedient which really destroyed the property and left a mere name.
The object of the old metaphysical theology was to see how far unassisted reason could go in the knowledge of God. Certainly a reason-derived knowledge of God is the highest problem of philosophy. The earliest teachings of religion are figurate conceptions of God. These conceptions, as the Creed arranges them, are imparted to us in youth. They are the doctrines of our religion, and in so far as the individual rests his faith on these doctrines and feels them to be the truth, he has all he needs as a Christian. Such is faith: and the science of this faith is Theology. But until Theology is something more than a bare enumeration and compilation of these doctrines ab extra, it has no right to the title of science. Even the method so much in vogue at present—the purely historical mode of treatment—which for example reports what has been said by this or the other Father of the Church—does not invest theology with a scientific character. To get that, we must go on to comprehend the facts by thought,—which is the business of philosophy. Genuine theology is thus at the same time a real philosophy of religion, as it was, we may add, in the Middle Ages.
And now let us examine this rational theology more narrowly. It was a science which approached God not by reason but by understanding, and, in its mode of thought, employed the terms without any sense of their mutual limitations and connexions. The notion of God formed the subject of discussion; and yet the criterion of our knowledge was derived from such an extraneous source as the materialised conception of God. Now thought must be free in its movements. It is no doubt to be remembered, that the result of independent thought harmonises with the import of the Christian religion:—for the Christian religion is a revelation of reason. But such a harmony surpassed the efforts of rational theology. It proposed to define the figurate conception of God in terms of thought; but it resulted in a notion of God which was what we may call the abstract of positivity or reality, to the exclusion of all negation. God was accordingly defined to be the most real of all beings. Any one can see however that this most real of beings, in which negation forms no part, is the very opposite of what it ought to be and of what understanding supposes it to be. Instead of being rich and full above all measure, it is so narrowly conceived that it is, on the contrary, extremely poor and altogether empty. It is with reason that the heart craves a concrete body of truth; but without definite feature, that is, without negation, contained in the notion, there can only be an abstraction. When the notion of God is apprehended only as that of the abstract or most real being, God is, as it were, relegated to another world beyond: and to speak of a knowledge of him would be meaningless. Where there is no definite quality, knowledge is impossible. Mere light is mere darkness.
The second problem of rational theology was to prove the existence of God. Now, in this matter, the main point to be noted is that demonstration, as the understanding employs it, means the dependence of one truth on another. In such proofs we have a pre-supposition—something firm and fast, from which something else follows; we exhibit the dependence of some truth from an assumed starting-point. Hence, if this mode of demonstration is applied to the existence of God, it can only mean that the being of God is to depend on other terms, which will then constitute the ground of his being. It is at once evident that this will lead I to some mistake: for God must be simply and solely the I ground of everything, and in so far not dependent upon anything else. And a perception of this danger has in modern times led some to say that God's existence is not capable of proof, but must be immediately or intuitively apprehended. Reason, however, and even sound common sense give demonstration a meaning quite different from that of the understanding. The demonstration of reason no doubt starts from something which is not God. But, as it advances, it does not leave the starting-point a mere unexplained fact, which is what it was. On the contrary it exhibits that point as derivative and called into being, and then God is seen to be primary, truly immediate and self-subsisting, with the means of derivation wrapt up and absorbed in himself. Those who say: 'Consider Nature, and Nature will-lead you to God; you will find an absolute final cause: 'do not mean that God is something derivative: they mean that it is we who proceed to God himself from another; and in this way God, though the consequence, is also the absolute' ground of the initial step. The relation of the two things is reversed; and what came as a consequence, being shown to be an antecedent, the original antecedent is reduced to a consequence. This is always the way, moreover, whenever reason demonstrates.
If in the light of the present discussion we cast one glance more on the metaphysical method as a whole, we find its main characteristic was to make abstract identity its principle and to try to apprehend the objects of reason by the abstract and finite categories of the understanding. But this infinite of the understanding, this pure essence, is still finite: it has excluded all the variety of particular things, which thus limit and deny it. Instead of winning a concrete, this metaphysic stuck fast on an abstract, identity. Its good point was the perception that thought alone constitutes the essence of all that is. It derived its materials from earlier philosophers, particularly the Schoolmen. In speculative philosophy the understanding undoubtedly forms a stage, but not a stage at which we should keep for ever standing. Plato is no metaphysician of this imperfect type, still less Aristotle, although the contrary is generally believed.
