That such a justice exists we all of us know, for we all have felt its irresistible power. We are well aware that it covers the whole of our life, and that at its centre there reigns an intelligence which never deceives itself, which none can deceive. But where shall we place it, now that we have torn it down from the skies? Where does it weigh good and evil, happiness and disaster? Whence does it issue to deal out reward and punishment? These are questions that we do not often ask ourselves, but they have their importance. The nature of justice, and all our morality, depend on the answer; and it cannot be fruitless therefore to inquire how that great idea of mystic and sovereign justice, which has undergone more than one transformation since history began, is being received to-day in the mind and the heart of man. And is this mystery not the loftiest, the most passionately interesting, of all that remain to us: does it not intertwine with most of the others? Do its vacillations not stir us to the very depths of our soul? The great bulk of mankind perhaps know nothing of these vacillations and changes, but for the evolution of thought it suffices that the eyes of the few should see; and when the clear consciousness of these has become aware of the transformation, its influence will gradually attain the general morality of men.

In these pages we shall naturally have much to say of social justice: of the justice, in other words, that we mutually extend to each other through life; but we shall leave on one side legal or positive justice, which is merely the organisation of one side of social justice. We shall occupy ourselves above all with that vague but inevitable justice, intangible and yet so effective, which accompanies and sets its seal upon every action of our life; which approves or disapproves, rewards or punishes. Does this come from without? Does an inflexible, undeceivable moral principle exist, independent of man, in the universe and in things? Is there, in a word, a justice that might be called mystic? Or does it issue wholly from man; is it inward even though it act from without; and is the only justice therefore psychologic? These two terms, mystic and psychologic justice, comprehend, more or less, all the different forms of justice, superior to the social, that would appear to exist to-day.

It is scarcely conceivable that any one who has forsaken the easy, but artificially illumined, paths of positive religion, can still believe in the existence of a physical justice arising from moral causes, whether its manifestations assume the form of heredity or disease, of geologic, atmospheric, or other phenomena. However eager his desire for illusion or mystery, this is a truth he is bound to recognise from the moment he begins earnestly and sincerely to study his own personal experience, or to observe the external ills which, in this world of ours, fall indiscriminately on good and wicked alike. Neither the earth nor the sky, neither nature nor matter, neither air nor any force known to man (save only those that are in him) betrays the slightest regard for justice, or the remotest connection with our morality, our thoughts or intentions. Between the external world and our actions there exist only the simple and essentially non-moral relations of cause and effect. If I am guilty of a certain excess or imprudence, I incur a certain danger, and have to pay a corresponding debt to nature. And as this imprudence or excess will generally have had an immoral cause—or a cause that we call immoral because we have been compelled to regulate our life according to the requirements of our health and tranquillity—we cannot refrain from establishing a connection between this immoral cause and the danger to which we have been exposed, or the debt we have had to pay; and we are led once more to believe in the justice of the universe, the prejudice which, of all those that we cling to, has its root deepest in our heart. And in our eagerness to restore this confidence we are content deliberately to ignore the fact that the result would have been exactly the same had the cause of our excess or imprudence been—to use the terms of our infantine vocabulary—heroic or innocent. If on an intensely cold day I throw myself into the water to save a fellow-creature from drowning, or if, seeking to drown him, I chance to fall in, the consequences of the chill will be absolutely the same; and nothing on this earth or beneath the sky—save only myself, or man if he be able—will enhance my suffering because I have committed a crime, or relieve my pain because my action was virtuous.

Let us consider another form of physical justice: heredity. There again we find the same indifference to moral causes. And truly it were a strange justice indeed that would throw upon the son, and even the remote descendant, the burden of a fault committed by his father or his ancestor. But human morality would raise no objection: man would not protest. To him it would seem natural, magnificent, even fascinating. It would indefinitely prolong his individuality, his consciousness and existence; and from this point of view would accord with a number of indisputable facts which prove that we are not wholly self-contained, but connect, in more than one subtle, mysterious fashion, with all that surrounds us in life, with all that precedes us, or follows.

And yet, true as this may be in certain cases, it is not true as regards the justice of physical heredity, which is absolutely indifferent to the moral causes of the deed whose consequences the descendants have to bear. There is physical relation between the act of the father, whereby he has undermined his health, and the consequent suffering of the son; but the son's suffering will be the same whatever the intentions or motives of the father, be these heroic or shameful. And, further, the area of what we call the justice of physical heredity would appear to be very restricted. A father may have been guilty of a hundred abominable crimes, he may have been a murderer, a traitor, a persecutor of the innocent or despoiler of the wretched, without these crimes leaving the slightest trace upon the organism of his children. It is enough that he should have been careful to do nothing that might injure his health.

So much for the justice of Nature as shown in physical heredity. Moral heredity would appear to be governed by similar principles; but as it deals with modifications of the mind and character infinitely more complex and more elusive, its manifestations are less striking, and its results less certain. Pathology is the only region which admits of its definite observation and study; and there we observe it to be merely the spiritual form of physical heredity, which is its essential principle: moral heredity being only a sequel, and revealing in its elementary stage the same indifference to real justice, and the same blindness. Whatever the moral cause of the ancestor's drunkenness or debauch, the same punishment may be meted out in mind and body to the descendants of the drunkard or the debauchee. Intellectual blemish will almost always accompany material blemish. The soul will be attacked simultaneously with the body; and it matters but little whether the victim be imbecile, mad, epileptic, possessed of criminal instincts, or only vaguely threatened with slight mental derangement: the most frightful moral penalty that a supreme justice could invent has followed actions which, as a rule, cause less harm and are less perverse than hundreds of other offences that Nature never dreams of punishing. And this penalty, moreover, is inflicted blindly, not the slightest heed being paid to the motives underlying the actions, motives that may have been excusable perhaps, or indifferent, or possibly even admirable.
