This example will serve to explain the whole phaenomena of the human will. This will, or rather the brain, finds itself in the same situation as a bowl, which although it has received an impulse that drives it forward in a straight line, is deranged in its course, whenever a force, superior to the first, obliges it to change its direction. The man who drinks the poisoned water, appears a madman; but the actions of fools are as necessary as those of the most prudent individuals. The motives that determine the voluptuary, that actuate the debauchee to risk their health, are as powerful, their actions are as necessary, as those which decide the wise man to manage his. But, it will be insisted, the debauchee may be prevailed on to change his conduct; this does not imply that he is a free agent; but, that motives may be found sufficiently powerful to annihilate the effect of those that previously acted upon him; then these new motives determine his will to the new mode of conduct he may adopt, as necessarily as the former did to the old mode.
Man is said to _deliberate_ when the action of the will is suspended; this happens when two opposite motives act alternately upon him. To deliberate, is to hate and to love in succession; it is to be alternately attracted and repelled; it is to be moved sometimes by one motive, sometimes by another. Man only deliberates when he does not distinctly understand the quality of the objects from which he receives impulse, or when experience has not sufficiently apprised him of the effects, more or less remote, which his actions will produce. He would take the air, but the weather is uncertain; he deliberates in consequence; he weighs the various motives that urge his will to go out or to stay at home; he is at length determined by that motive which is most probable; this removes his indecision, which necessarily settles his will either to remain within or to go abroad: this motive is always either the immediate or ultimate advantage he finds or thinks he finds in the action to which he is persuaded.
Man's will frequently fluctuates between two objects, of which either the presence or the ideas move him alternately: he waits until he has contemplated the objects or the ideas they have left in his brain; which solicit him to different actions; he then compares these objects or ideas: but even in the time of deliberation, during the comparison, pending these alternatives of love and hatred, which succeed each other sometimes with the utmost rapidity, he is not a free agent for a single instant; the good or the evil which he believes he finds successively in the objects, are the necessary motives of these momentary wills; of the rapid motion of desire or fear that he experiences as long as his uncertainty continues. From this it will be obvious, that deliberation is necessary; that uncertainty is necessary; that whatever part he takes, in consequence of this deliberation, it will always necessarily be that which he has judged, whether well or ill, is most probable to turn to his advantage.
