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.
