he was allured to acquiesce; he would discover, that all the motives of his labours, of his amusements, of his discourses, of his thoughts, have been necessary; that they have evidently either seduced him or drawn him along. Is he the master of willing, not to withdraw his hand from the fire when he fears it will be burnt? Or has he the power to take away from fire the property which makes him fear it? Is he the master of not choosing a dish of meat which he knows to be agreeable, or analogous to his palate; of not preferring it to that which he knows to be disagreeable or dangerous? It is always according to his sensations, to his own peculiar experience, or to his suppositions, that he judges of things either well or ill; but whatever way be his judgment, it depends necessarily on his mode of feeling, whether habitual or accidental, and the qualities he finds in the causes that move him, which exist in despite of himself. All the causes which by his will is actuated, must act upon him in a manner sufficiently marked, to give him some sensation, some perception, some idea, whether complete or incomplete, true or false; as soon as his will is determined, he must have felt, either strongly or feebly; if this was not the case he would have determined without motive: thus, to speak correctly, there are no causes which are truly indifferent to the will: however faint the impulse he receives, whether on the part of the objects themselves, or on the part of their images or ideas, as soon as his will acts, the impulse has been competent to determine him. In consequence of a slight, of a feeble impulse, the will is weak, it is this weakness of the will that is called _indifference_. His brain with difficulty perceives the sensation, it has received; it consequently acts with less vigour, either to obtain or remove the object or the idea that has modified it. If the impulse is powerful, the will is strong, it makes him act vigorously, to obtain or to remove the object which appears to him either very agreeable or very incommodious.
