repelled by those beings which he believes prejudicial, either to his habitual, or to his transitory mode of existence; by that which he considers disadvantageous. It is only by the aid of experience, that man acquires the faculty of understanding what he ought to love; of knowing what he ought to fear. Are his organs sound? his experience will be true: are they unsound? it will be false: in the first instance he will have reason, prudence, foresight; he will frequently foresee very remote effects; he will know, that what he sometimes contemplates as a good, may possibly become an evil, by its necessary or probable consequences: that what must be to him a transient evil, may by its result procure him a solid and durable good. It is thus experience enables him to foresee that the amputation of a limb will cause him painful sensation, he consequently is obliged to fear this operation, and he endeavours to avoid the pain; but if experience has also shewn him, that the transitory pain this amputation will cause him may be the means of saving his life; the preservation, of his existence being of necessity dear to him, he is obliged to submit himself to the momentary pain with a view to procuring a permanent good, by which it will be overbalanced. The will, as we have elsewhere said, is a modification of the brain, by which it is disposed to action or prepared to give play to the organs. This will is necessarily determined by the qualities, good or bad, agreeable or painful, of the object or the motive that acts upon his senses; or of which the idea remains with him, and is resuscitated by his memory. In consequence, he acts necessarily; his action is the result of the impulse he receives either from the motive, from the object, or from the idea, which has modified his brain, or disposed his will. When he does not act according to this impulse, it is because there comes some new cause, some new motive, some new idea, which modifies his brain in a different manner, gives him a new impulse, determines his will in another way; by which the action of the former impulse is suspended: thus, the sight of an agreeable object, or its idea, determines his will to set him in action to procure it; but if a new object or a new idea more powerfully attracts him, it gives a new direction to his will, annihilates the effect of the former, and prevents the action by which it was to be procured. This is the mode in which reflection, experience, reason, necessarily arrests or suspends the action of man's will; without this, he would, of necessity, have followed the anterior impulse which carried him towards a then desirable object. In all this he always acts according to necessary laws, from which he has no means of emancipating himself.
