for the life of the soul be frustrated like the other? The partizans of the doctrine of the immortality of the soul reason thus: "All men desire to live for ever, therefore they will live for ever." Suppose the argument retorted on them; would it be believed? If it was asserted, "All men naturally desire to be rich; therefore all men will one day be rich," how many partizans would this doctrine find? The most simple reflection upon the nature of his soul, ought to convince man that the idea of its immortality is only an illusion of the brain. Indeed what is his soul, save the principle of sensibility? What is it, to think, to enjoy, to suffer; is it not to feel? What is life, except it be the assemblage of modifications, the congregation of motion, peculiar to an organized being? Thus, as soon as the body ceases to live, its sensibility can no longer exercise itself; when its sensibility is no more, it can no longer have ideas, nor in consequence thoughts. Ideas, as we have proved, can only reach man through his senses; now, how will they have it, that once deprived of his senses, he is yet capable of receiving sensations, of having perceptions, of forming ideas? As they have made the soul of man a being separated from the animated body, wherefore have they not made life a being distinguished from the living body? Life in a body is the totality of this motion; feeling and thought make a part of this motion: thus it is reasonable to suppose, that in the dead man these motions will cease, like all the others. Indeed, by what reasoning will it be proved, that this soul, which cannot feel, think, will, or act, but by aid of man's organs, can suffer pain, be susceptible of pleasure, or even have a consciousness of its own existence, when the organs which should warn it of their presence are decomposed or destroyed? Is it not evident, that the soul depends on the arrangement of the various parts of the body; on the order with which these parts conspire to perform their functions; on the combined motion of the whole? Thus the organic structure once destroyed, can it be reasonably doubted the soul will be destroyed also? Is it not seen, that during the whole course of human life this soul is stimulated, changed, deranged, disturbed, by all the changes man's organs experience? And yet it will be insisted, that this soul acts, thinks, subsists, when these same organs have entirely disappeared!
