Every thing becomes an impulse to the will; a single word frequently suffices to modify a man for the whole course of his life, to decide for ever his propensities; an infant who has burned his finger by having approached it too near the flame of a lighted taper, is warned from thence, that he ought to abstain from indulging a similar temptation; a man, once punished and despised for having committed a dishonest action, is not often tempted to continue so unfavourable a course. Under whatever point of man is considered, he never acts but after the impulse given to his will, whether it be by the will of others, or by more perceptible physical causes. The particular organization decides the nature of the impulse; souls act upon souls that are analogous; inflamed, fiery imaginations, act with facility upon strong passions; upon imaginations easy to be inflamed, the surprising progress of enthusiasm; the hereditary propagation of superstition; the transmission of religious errors from race to race, the excessive ardour with which man seizes on the marvellous, are effects as necessary as those which result from the action and re-action of bodies. In despite of the gratuitous ideas which man has formed to himself on his pretended free-agency; in defiance of the illusions of this suppose intimate sense, which, contrary to his experience, persuades him that he is master of his will,--all his institutions are really founded upon necessity: on this, as on a variety of other occasions, practice throws aside speculation. Indeed, if it was not believed that certain motives embraced the power requisite to determine the will of man, to arrest the progress of his passions, to direct them towards an end, to modify him; of what use would be the faculty of speech? What benefit could arise from education itself? What does education achieve, save give the first impulse to the human will, make man contract habits, oblige him to persist in them, furnish him with motives, whether true or false, to act after a given manner? When the father either menaces his son with punishment, or promises him a reward, is he not convinced these things will act upon his will? What does legislation attempt, except it be to present to the citizens of a state those motives which are supposed necessary to determine them to perform some actions that are considered worthy; to abstain from committing others that are looked upon as unworthy? What is the object of morals, if it be not to shew man that his interest exacts he should suppress the momentary ebullition of his passions, with a view to promote a more certain happiness, a more lasting well-being, than can possibly result from the gratification of his transitory desires? Does not the religion of all countries suppose the human race, together with the entire of Nature, submitted to the irresistible will of a necessary being, who regulates their condition after the eternal laws of immutable wisdom? Is not God the absolute
