Grandeur of Moral Law.

3. The truth thus reached on this point is one of exceeding importance. It brings to view the grandeur of the moral law. It shows this law to be truly transcendental, belonging not to transient material forms or physiological structure, nor to special psychical constitutions of men or races, nor organized instinct, nor subjective mental illusion, nor peculiar hereditary experience, nor transformed sense of realized or supposed utility, nor any local adventitious circumstances and training, but to the supreme super-sensible realm of universal and necessary ideas and truth, in which the universe of rational thought and divine order lives and moves and has its being and welfare. In this truth, therefore, the moral law begins to appear in its true greatness and value, in its universal dominion and infinite importance. It comes down upon us with a mighty impression. It thrills us into enthusiasm. As long as the moral idea is accounted a mere product of environment and biological evolution or experienced utility, a blind hereditary instinct, an organized impulse, a fiction of education, or a temporary behest of individual or racial organization, it is a thing of but little dignity and of limited moment. It is worthy of no more reverence than a form of protoplasm or a passing mental impression. Not reflecting an objective reality of universal, supreme and permanent validity, but only a special phenomenon of the human organization and this transient life, it can inspire but small respect. Only in the truth here reached does the authority of the moral law stand out in its majesty and illimitable range and sweep. Only in it can that law be rightly effective for the good conduct of men and the safe formation of character in the mould of immortal excellence.

Reality is Dividing Line.

4. The recognition of the objective validity of the moral distinctions marks one of the chief dividing lines between true and false theories of moral philosophy. A failure to recognize this point not only leaves the point itself a blank, but usually means error both in the conception of the nature and function of conscience and of the grounds and claims of right and virtue. With respect to conscience the failure reduces it from a power of true discernment of what is, into an instinct acting blindly or a make-believe of obligation through judgments indistinguishable from those of utility, pleasure or advantage, or into a passing product of racial experience or education. So instead of explaining the unique authority of the conscience it undermine and dissolves that authority into non-moral elements. Obligation itself becomes but a synonym for an impulse toward certain forms of pleasure or advantage. As to the grounds and claims of right, these are thus caused to disappear in the non-moral elements into which right and wrong are dissolved. The ethical distinctions, the great moral phenomena of the ages, with all the interests of practical morality, instead of being explained and justified, are explained away. If, therefore, ethical theory is to exhibit the metaphysical validity of the moral consciousness of men, no view can reasonably be regarded as correct that dissipates the very reality which the conscience assumes to see and without which the moral judgments lose their rational foundations. For if the objective and transcendent character of the ethical distinction be denied, morality necessarily drops down into, at best, a temporary biological provision for the utilities of this ephemeral life, or, at worst, into a deep fraud of our faculties, estopping the use of our freedom by a phantom bugbear of moral distinctions. If, therefore, virtue is not to be disrobed of its honor, if righteousness is not to be cast down from the supreme place which the reason of mankind has ever accorded it, if the idea of duty is not to be belittled, invalidated and overthrown, ethical theory must recognize and emphasize the objective and permanent reality of the moral law as an unchanging law of obligation and responsibility for the conduct of free agents. Otherwise the so-called ethical theory is not a theory of the ethical reality, but one that sinks the supposed ethical reality into non-moral elements and illusion. To vindicate the authority of conscience, the immutable foundations of righteousness must be maintained, not dissolved.

Relation to Evolution.

5. The relation of this truth to the wide-spread hypothesis of the evolutionary origin of man dare not be ignored at this place. Frank admission has already been made that this hypothesis, as setting forth a mere mode of creation by God, does not appear to be necessarily inconsistent with the existence of conscience. Any mode that can produce a faculty of mental power capable of perceiving or making the ethical distinction, suffices on that point—though grave difficulties stand in the way of accounting for it under any evolutionist explanation thus far given. But how is it with respect to the supersensible reality of the moral law, as the reality perceived by the conscience? Can evolution account for it, or even allow any place for it?

Theistic Evolution.

To these questions, the answer must be, first, that evolution, in the theistic conception, if supposed capable of developing the faculty of conscience, must also be regarded as consistent with existence and place of the moral law. The infinite intelligence and purpose back of the creative evolution, and through it originating a power for ethical perception, must be conceded to be equally capable, in that method of forming the universe, of establishing the principle and law of duty in the relations in which rational and self-determining creatures are to live. Provided only that a rational first cause be assumed and the plan of the world be viewed as laid in aims of divine order, a moral system as well as moral agents may, surely, be created by slow advance of life no less completely than by instantaneous fiat of power. The theistic theory of evolution, assuming the cosmic system to be grounded in the will and power of God and filled with his ever-working presence does not necessarily bring any trouble into the question of fixed moral law. The moral law, resting in the same divine source whence arise the laws that are revealed in physical nature, comes into play as soon as moral agents are created in relations which call for right sentiments and conduct. The rational purpose which ordained physical laws, in necessity, for material order, ordains moral law for order of personal agents acting in freedom. The question, therefore, with respect to this kind of evolution need not embarrass the question of the reality of immutable moral law—at least when the theory of evolution is so shaped as to give its fundamental assumptions full and consistent place and force.

Atheistic Evolution.

But, secondly, on the other hand, answer must be made, that under no theory of atheistic and merely materialistic and naturalistic evolution can the objective existence of moral law be logically or rationally maintained. This kind of evolutionism is not only helpless before the task of accounting for it, but logically excludes the possibility of it. For any theory that presents the cosmos as a pure naturalism of matter, or is agnostic as to an intelligent author of nature, furnishes no realm or materials for moral law. This becomes evident, beyond doubt, from the following considerations:
