Human Nature, and Other Sermons

[7] Every man in his physical nature is one individual single agent. He has likewise properties and principles, each of which may be considered separately, and without regard to the respects which they have to each other. Neither of these is the nature we are taking a view of. But it is the inward frame of man considered as a system or constitution: whose several parts are united, not by a physical principle of individuation, but by the respects they have to each other; the chief of which is the subjection which the appetites, passions, and particular affections have to the one supreme principle of reflection or conscience. The system or constitution is formed by and consists in these respects and this subjection. Thus the body is a system or constitution: so is a tree: so is every machine. Consider all the several parts of a tree without the natural reselects they have to each other, and you have not at all the idea of a tree; but add these respects, and this gives you the idea. This body may be impaired by sickness, a tree may decay, a machine be out of order, and yet the system and constitution of them not totally dissolved. There is plainly somewhat which answers to all this in the moral constitution of man. Whoever will consider his own nature will see that the several appetites, passions, and particular affections have different respects amongst themselves. They are restraints upon, and are in a proportion to, each other. This proportion is just and perfect, when all those under principles are perfectly coincident with conscience, so far as their nature permits, and in all cases under its absolute and entire direction. The least excess or defect, the least alteration of the due proportions amongst themselves, or of their coincidence with conscience, though not proceeding into action, is some degree of disorder in the moral constitution. But perfection, though plainly intelligible and unsupportable, was never attained by any man. If the higher principle of reflection maintains its place, and as much as it can corrects that disorder, and hinders it from breaking out into action, this is all that can be expected in such a creature as man. And though the appetites and passions have not their exact due proportion to each other, though they often strive for mastery with judgment or reflection, yet, since the superiority of this principle to all others is the chief respect which forms the constitution, so far as this superiority is maintained, the character, the man, is good, worthy, virtuous.
