T 2.2.10.10

This uneasiness, which is common to every spectator, must be more sensible to the superior; and that because the near approach of the inferior is regarded as a piece of ill-breeding, and shews that he is not sensible of the disproportion, and is no way affected by it. A sense of superiority in another breeds in all men an inclination to keep themselves at a distance from him, and determines them to redouble the marks of respect and reverence, when they are oblig'd to approach him; and where they do not observe that conduct, 'tis a proof they are not sensible of his superiority. From hence too it proceeds, that any great difference in the degrees of any quality is call'd a distance by a common metaphor, which, however trivial it may appear, is founded on natural principles of the imagination. A great difference inclines us to produce a distance. The ideas of distance and difference are, therefore, connected together. Connected ideas are readily taken for each other; and this is in general the source of the metaphor, as we shall have occasion to observe afterwards.
