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.==
