taken notice of. And this difference, not being a difference in strength or degree, I call a difference in nature and in kind. And since, in the instance still before us, if passion prevails over self-love, the consequent action is unnatural; but if self-love prevails over passion the action is natural; it is manifest, that self-love is in human nature a superior principle to passion. This may be contradicted without violating that nature, but the former cannot. So that, if we will act conformably to the economy of man's nature, reasonable self-love must govern. Thus, without particular consideration of conscience, we may have a clear conception of the superior nature of one inward principle to another; and see that there really is this natural superiority, quite distinct from degrees of strength and prevalency.
Let us now take a view of the nature of man, as consisting partly of various appetites, passions, affections, and partly of the principle of reflection, of conscience; leaving quite out all consideration of the different degrees of strength, in which either of them prevail; and it will further appear, that there is this natural superiority of one inward principle to another, or that it is even part of the idea of reflection or conscience.
Passion or appetite implies a direct simple tendency towards such and such objects, without distinction of the means by which they are to be obtained. Consequently, it will often happen there will be a desire of particular objects, in cases where they cannot be obtained without manifest injury to others. Reflection, or conscience, comes in, and disapproves the pursuit of them in these circumstances; but the desire remains. Which is to be obeyed, appetite or reflection? Cannot this question be answered from the economy and constitution of human nature merely, without saying which is strongest? or need this all come into consideration? Would not the question be intelligibly and fully answered by saying, that the principle of reflection or conscience being compared with the various appe-
