dilemmas, and the impossibility there often is of finding any just medium, oblige us, when we reflect on the matter, to acknowledge, that all property and obligations are entire. But on the other hand, when we consider the origin of property and obligation, and find that they depend on public utility, and sometimes on the propensities of the imagination, which are seldom entire on any side; we are naturally inclin'd to imagine, that these moral relations admit of an insensible gradation. Hence it is, that in references, where the consent of the parties leave the referees entire masters of the subject, they commonly discover so much equity and justice on both sides, as induces them to strike a medium, and divide the difference betwixt the parties. Civil judges, who have not this liberty, but are oblig'd to give a decisive sentence on some one side, are often at a loss how to determine, and are necessitated to proceed on the most frivolous reasons in the world. Half rights and obligations, which seem so natural in common life, are perfect absurdities in their tribunal; for which reason they are often oblig'd to take half arguments for whole ones, in order to terminate the affair one way or other.
III. The third argument of this kind I shall make use of may be explain'd thus. If we consider the ordinary course of human actions, we shall find, that the mind restrains not itself by any general and universal rules; but acts on most occasions as it is determin'd by its present motives and inclination. As each action is a particular individual event, it must proceed from particular principles, and from our immediate situation within ourselves, and with respect to the rest of the universe. If on some occasions we extend our motives beyond those very circumstances, which gave rise to them, and form something like general rules for our conduct, tis easy to observe, that these rules are not perfectly inflexible, but allow of many exceptions. Since, therefore, this is the ordinary course of human actions, we may conclude,
