Holbach begins by a most unflinching exposure of the inconsistency with all that we know of nature, of the mysterious theory of Free Will. This remains one of the most effective parts of the book, and perhaps the work has never been done with a firmer hand. The conclusion is expressed with a decisiveness that almost seems crude. There is declared to be no difference between a man who throws himself out of the window and the man whom I throw out, except this, that the impulse acting on the second comes from without, and that the impulse determining the fall of the first comes from within his own mechanism. You have only to get down to the motive, and you will invariably find that the motive is beyond the actor’s own power or reach. The inexorable logic with which the author presses the Free-Willer from one retreat to another, and from shift to shift, leaves his adversary at last exactly as naked and defenceless before Holbach’s vigorous and thoroughly realised Naturalism as the same adversary must always be before Jonathan Edwards’s vigorous theism. “The system of man’s liberty,” Holbach says (II. ii.), with some pungency, “seems only to have been invented in order to put him in a position to offend his God, and so to justify God in all the evil that he inflicted on man, for having used the freedom which was so disastrously conferred upon him.”
If man be not free, what right have we to punish those who cannot help committing bad actions, or to reward others who cannot help committing good actions? Holbach gives to this and the various other ways of describing fatalism as dangerous to society, the proper and perfectly adequate answer. He turns to the quality of the action, and connects with that the social attitude of praise and blame. Merit and demerit are associated with conduct, according as it is thought to affect the common welfare advantageously or the reverse. My indignation and my approval are as necessary as the acts that excite these sentiments. My feelings are neither more nor less spontaneous than the deciding motives of the actor. Whatever be the necessitating cause of our actions, I have a right to do my best by praise and blame, by reward and punishment, to strengthen or to weaken, to prolong or to divert, the motives that are the antecedents of the action; exactly as I have a right to dam up a stream, or to divert its course, or otherwise deal with it to suit my own convenience. Penal laws, for instance, are ways of offering to men strong motives, to weigh in the scale against the temptation of an immediate personal gratification. Holbach does not make it quite distinct that the object of penal legislation is in some cases to give the offender, as well as other people, a strong reason for thinking twice before he repeats the offence; yet in other cases, where the punishment is capital, the legislation does not aim at influencing the mind of the offender at all, but the minds of other people only. This is only a side illustration of a common weakness in most arguments on this subject. A thorough vindication of the penal laws, on the principles of a systematic fatalism, can only be successful, if we think less of the wrongdoer in any given case, than of affecting general motives, and building up a right habit of avoiding or accepting certain classes of action.
The writer then justly connects his scientific necessarianism in philosophy with humanity in punishment. He protests against excessive cruelty in the infliction of legal penalties, and especially against the use of torture, on two grounds; first, that experience demonstrates the uselessness of these superfluous rigours; and, second, that the habit of witnessing atrocious punishments familiarises both criminals and others with the idea of cruelty. The acquiescence of Paris for a few months in the cruelties of the Terror was no doubt due, on Holbach’s perfectly sound principle, to the far worse cruelties with which the laws had daily made Paris familiar down to the last years of the monarchy. And Holbach was justified in expecting a greater degree of charitable and considerate judgment from the establishment in men’s minds of a Necessarian theory. We are no longer vindictive against the individual doer; we wax energetic against the defective training and the institutions which allowed wrong motives to weigh more heavily with him than right ones. Punishment on the theory of necessity ought always to go with prevention, and is valued just because it is a force on prevention, and not merely an element in retribution.
Holbach answers effectively enough the common objection that his fatalism would plunge men’s souls into apathy. If all is necessary, why shall I not let things go, and myself remain quiet? As if we could stay our hands from action, if our feelings were trained to proper sensibility and sympathy. As if it were possible for a man of tender disposition not to interest himself keenly in all that concerns the lot of his fellow-creatures. How does our knowledge that death is necessary prevent us from deploring the loss of a beloved one? How does my consciousness that it is the inevitable property of fire to burn, prevent me from using all my efforts to avert a conflagration?
Finally, when people urge that the doctrine of necessity degrades man by reducing him to a machine, and likening him to some growth of abject vegetation, they are merely using a kind of language that was invented in ignorance of what constitutes the true dignity of man. What is nature itself but a vast machine, in which our human species is no more than one weak spring? The good man is a machine whose springs are adapted so to fulfil their functions as to produce beneficent results for his fellows. How could such an instrument not be an object of respect and affection and gratitude?
In closing this part of Holbach’s book, while not dissenting from his conclusions, we will only remark how little conscious he seems of the degree to which he empties the notions of praise and blame of the very essence of their old contents. It is not a modification, but the substitution of a new meaning under the old names. Praise in its new sense of admiration for useful and pleasure-giving conduct or motive, is as powerful a force and as adequate an incentive to good conduct and good motives, as praise in the old sense of admiration for a deliberate and voluntary exercise of a free-acting will. But the two senses are different. The old ethical association is transformed into something which usage and the requirements of social self-preservation must make equally potent, but which is not the same. If Holbach and others who hold necessarian opinions were to perceive this more frankly, and to work it out fully, they would prevent a confusion that is very unfavourable to them in the minds of most of those whom they wish to persuade. It is easy to see that the work next to be done in the region of morals, is the readjustment of the ethical phraseology of the volitional stage, to fit the ideas proper to the stage in which man has become as definitely the object of science as any of the other phenomena of the universe.
The chapter (xiii.) on the Immortality of the Soul examines this memorable growth of human belief with great vigour, and a most destructive penetration. As we have seen, the author repudiates the theory of a double energy in man, one material and the other spiritual, just as he afterwards repudiates the analogous hypothesis of a double energy in nature, one of the two being due to a spiritual mover outside of the external phenomena of the universe. Consistently with this renunciation of a separate spiritual energy in man, Holbach will listen to no talk of a spiritual energy surviving the destruction of the mechanical framework. To say that the soul will feel, think, enjoy, suffer, after the death of the body, is to pretend that a clock broken into a thousand pieces can continue to strike or to mark the hours. And having emphatically proclaimed his own refusal to share the common belief, he proceeds with good success to carry the war into the country of those who profess that belief, and defend it as the safeguard of society. We need not go through his positions. They are substantially those which are familiar to everybody who has read the Third Book of Lucretius’s poem, and remembers those magnificent passages which are not more admirable in their philosophy than they are noble and moving in their poetic expression:—
Nam veluti pueri trepidant atque omnia caecis
In tenebris metuunt, sic nos in luce timemus
Interdum, nilo quae sunt metuenda magis quam
Quae pueri in tenebris pavitant finguntque futura.
Hunc igitur terrorem animi tenebrasque necessest
Non radii solis neque lucida tela diei
Discutiant, sed naturae species ratioque.
And so forth, down to the exquisite lines—
“Jam jam non domus accipiet te laeta, neque uxoi
Optima nec dulces occurrent oscula nati
Praeripere, et tacita pectus dulcedine tangent.
Non poteris factis florentibus esse, tuisque
Praesidium. Misero misere,” aiunt, “omnia ademit
Una dies infesta tibi tot praemia vitae.”
Illud in his rebus non addunt, “nec tibi earum
Jam desiderium rerum super insidet una.”
Quod bene si videant animo dictisque sequantur,
Dissolvant animi magno se angore metuque.
“Tu quidem ut es leto sopitus, sic eris aevi
Quod superest cunctis privatu’ doloribus aegris:
At nos horrifico cinefactum te prope busto
Insatiabiliter deflevimus, aeternumque Nulla dies nobis maerorem e pectore demet.”
Illud ab hoc igitur quaerendum est, quid sit amari
Tanto opere, ad somnum si res redit atque quietem,
Cur quisquam æterno possit tabescere luctu.
