Demonstrative, or certain, or absolute knowledge of the actual nature of things would, Browning asserts, destroy the very possibility of a moral life.A For such knowledge would show either that evil is evil, or that evil is good; and, in both cases alike, the benevolent activity of love would be futile. In the first case, it would be thwarted and arrested by despair; for, if evil be evil, it must remain evil for aught that man can do. Man cannot effect a change in the nature of things, nor create a good in a world dominated by evil. In the second case, the saving effect of moral love would be unnecessary; for, if evil be only seeming, then all things are perfect and complete, and there is no need of interference. It is necessary, therefore, that man should be in a permanent state of doubt as to the real existence of evil; and, whether evil does exist or not, it must seem, and only seem to exist to man, in order that he may devote himself to the service of good.B

Now, if this view of the poet be taken in the strict sense in which he uses it in this argument, it admits of a very easy refutation. It takes us beyond the bounds of all possible human experience, into an imaginary region, as to which all assertions are equally valueless. It is impossible to conceive how the conduct of a being who is moral would be affected by absolute knowledge; or, indeed, to conceive the existence of such a being. For morality, as the poet insists, is a process in which an ideal is gradually realized through conflict with the actual—an actual which it both produces and transmutes at every stage of the progress. But complete knowledge would be above all process. Hence we would have, on Browning's hypothesis, to conceive of a being in whom perfect knowledge was combined with an undeveloped will. A being so constituted would be an agglomerate of utterly disparate elements, the interaction of which in a single character it would be impossible to make intelligible.

But, setting aside this point, there is a curious flaw in Browning's argument, which indicates that he had not distinguished between two forms of optimism which are essentially different from each other,—namely, the pantheistic and the Christian.

To know that evil is only apparent, that pain is only pleasure's mask, that all forms of wickedness and misery are only illusions of an incomplete intelligence, would, he argues, arrest all moral action and stultify love. For love—which necessarily implies need in its object—is the principle of all right action. In this he argues justly, for the moral life is essentially a conflict and progress; and, in a world in which "white ruled unchecked along the line," there would be neither the need of conflict nor the possibility of progress. And, on the other hand, if the good were merely a phantom, and evil the reality, the same destruction of moral activity would follow. "White may not triumph," in this absolute manner, nor may we "clean abolish, once and evermore, white's faintest trace." There must be "the constant shade cast on life's shine."

All this is true; but the admission of it in no way militates against the conception of absolutely valid knowledge; nor is it any proof that we need live in the twilight of perpetual doubt, in order to be moral. For the knowledge, of which Browning speaks, would be knowledge of a state of things in which morality would be really impossible; that is, it would be knowledge of a world in which all was evil or all was good. On the other hand, valid knowledge of a world in which good and evil are in conflict, and in which the former is realized through victory over the latter, would not destroy morality. What is inconsistent with the moral life is the conception of a world where there is no movement from evil to good, no evolution of character, but merely the stand-still life of "Rephan." But absolutely certain knowledge that the good is at issue with sin in the world, that there is no way of attaining goodness except through conflict with evil, and that moral life, as the poet so frequently insists, is a process which converts all actual attainment into a dead self, from which we can rise to higher things—a self, therefore, which is relatively evil—would, and does, inspire morality. It is the deification of evil not negated or overcome, of evil as it is in itself and apart from all process, which destroys morality. And the same is equally true of a pantheistic optimism, which asserts that all things are good. But it is not true of a Christian optimism, which asserts that all things are working together for good. For such optimism implies that the process of negating or overcoming evil is essential to the attainment of goodness; it does not imply that evil, as evil, is ever good. Evil is unreal, only in the sense that it cannot withstand the power which is set against it. It is not mere semblance, a mere negation or absence of being; it is opposed to the good, and its opposition can be overcome, only by the moral effort which it calls forth. An optimistic faith of this kind can find room for morality; and, indeed, it furnishes it with the religious basis it needs. Browning, however, has confused these two forms of optimism; and, therefore, he has been driven to condemn knowledge, because he knew no alternative but that of either making evil eternally real, or making it absolutely unreal. A third alternative, however, is supplied by the conception of moral evolution. Knowledge of the conditions on which good can be attained—a knowledge that amounts to conviction—is the spring of all moral effort; whereas an attitude of permanent doubt as to the distinction between good and evil would paralyse it. Such a doubt must be solved before man can act at all, or choose one end rather than another. All action implies belief, and the ardour and vigour of moral action can only come from a belief which is whole-hearted.

The further assertion, which the poet makes in La Saisiaz, and repeats elsewhere, that sure knowledge of the consequences that follow good and evil actions would necessarily lead to the choice of good and the avoidance of evil, and destroy morality by destroying liberty of choice, raises the whole question of the relation of knowledge and conduct, and cannot be adequately discussed here. It may be said, however, that it rests upon a confusion between two forms of necessity: namely, natural and spiritual necessity. In asserting that knowledge of the consequences of evil would determine human action in a necessary way, the poet virtually treats man as if he were a natural being. But the assumption that man is responsible and liable to punishment, involves that he is capable of withstanding all such determination. And knowledge does not and cannot lead to such necessary determination. Reason brings freedom; for reason constitutes the ends of action.

It is the constant desire of the good to attain to such a convincing knowledge of the worth and dignity of the moral law that they shall be able to make themselves its devoted instruments. Their desire is that "the good" shall supplant in them all motives that conflict against it, and be the inner principle, or necessity, of all their actions. Such complete devotion to the good is expressed, for instance, in the words of the Hebrew Psalmist: "Thy testimonies have I taken as an heritage for ever; for they are the rejoicing of my heart. I have inclined mine heart to perform Thy statutes alway, even unto the end. I hate vain thoughts, but Thy law do I love." "Nevertheless I live," said the Christian apostle, "yet not I, but Christ liveth in me; and the life which I now live in the flesh I live by the faith of the Son of God." In these words there is expressed that highest form of the moral life, in which the individual is so identified in desire with his ideal, that he lives only to actualize it in his character. The natural self is represented as dead, and the victory of the new principle is viewed as complete. This full obedience to the ideal is the service of a necessity; but the necessity is within, and the service is, therefore, perfect freedom. The authority of the law is absolute, but the law is self-imposed. The whole man is convinced of its goodness. He has acquired something even fuller than a mere intellectual demonstration of it; for his knowledge has ripened into wisdom, possessed his sympathies, and become a disposition of his heart. And the fulness and certainty of his knowledge, so far from rendering morality impossible, is its very perfection. To bring about such a knowledge of the good of goodness and the evil of evil, as will engender love of the former and hatred of the latter, is the aim of all moral education. Thus, the history of human life, in so far as it is progressive, may be concentrated in the saying that it is the ascent from the power of a necessity which is natural, to the power of a necessity which is moral. And this latter necessity can come only through fuller and more convincing knowledge of the law that rules the world, and is also the inner principle of man's nature.
