tho' this be universally true, 'tis remarkable that the passion of love may be excited by only one relation of a different kind, viz. betwixt ourselves and the object; or more properly speaking, that this relation is always attended with both the others. Whoever is united to us by any connexion is always sure of a share of our love, proportion'd to the connexion, without enquiring into his other qualities. Thus the relation of blood produces the strongest tie the mind is capable of in the love of parents to their children, and a lesser degree of the same affection, as the relation lessens. Nor has consanguinity alone this effect, but any other relation without exception. We love our country-men, our neighbours, those of the same trade, profession, and even name with ourselves. Every one of these relations is esteemed some tie, and gives a title to a share of our affection.
There is another phænomenon, which is parallel to this, viz. that acquaintance, without any kind of relation, gives rise to love and kindness, When we have contracted a habitude and intimacy with any person; tho' in frequenting his company we have not been able to discover any very valuable quality, of which he is possess'd; yet we cannot forbear preferring him to strangers, of whose superior merit we are fully convinc'd. These two phænomena of the effects of relation and acquaintance will give mutual light to each other, and may be both explain'd from the same principle.

From this, say they, proceeds that continual search after amusement in gaming, in hunting, in business; by which we endeavour to forget ourselves, and excite our spirits from the languid state, into which they fall, when not sustain'd by some brisk and lively emotion. To this method of thinking I so far agree, that I own the mind to be insufficient, of itself, to its own
