Man, in his origin, is an imperceptible point, a speck, of which the parts are without form; of which the mobility, the life, escapes his senses; in short, in which he does not perceive any sign of those qualities, called SENTIMENT, FEELING, THOUGHT, INTELLIGENCE, FORCE, REASON, &c. Placed in the womb suitable to his expansion, this point unfolds, extends, increases, by the continual addition of matter he attracts, that is analogous to his being, which consequently assimilates itself with him. Having quitted this womb, so appropriate to conserve his existence, to unfold his qualities, to strengthen his habits; so competent to give, for a season, consistence to the weak rudiments of his frame; he travels through the stage of infancy; he becomes adult: his body has then acquired a considerable extension of bulk, his motion is marked, his action is visible, he is sensible in all his parts; he is a living, an active mass; that is to say, a combination that feels and thinks; that fulfils the functions peculiar to beings of his species. But how has he become sensible? Because he has been by degrees nourished, enlarged, repaired by the continual attraction that takes place within himself, of that kind of matter which is pronounced inert, insensible, inanimate; which is, nevertheless, continually combining itself with his machine; of which it forms an active whole, that is living, that feels, judges, reasons, wills, deliberates, chooses, elects; that has the capability of labouring, more or less efficaciously, to his own individual preservation; that is to say, to the maintenance of the harmony of his existence. All the motion and changes that man experiences in the course of his life, whether it be from exterior objects or from those substances contained within himself, are either favorable or prejudicial to his existence; either maintain its order, or throw it into confusion; are either in conformity with, or repugnant to, the essential tendency of his peculiar mode of being. He is compelled by Nature to approve of some, to disapprove of others; some of necessity render him happy, others contribute to his misery; some become the objects of his most ardent desire, others of his determined aversion: some elicit his confidence, others make him tremble with fear.
