T 3.3.1.26

This theory may serve to explain, why the same qualities, in all cases, produce both pride and love, humility and hatred; and the same man is always virtuous or vicious, accomplish'd or despicable to others, who is so to himself. A person, in whom we discover any passion or habit, which originally is only incommodious to himself, becomes always disagreeable to us, merely on its account; as on the other hand, one whose character is only dangerous and disagreeable to others, can never be satisfied with himself, as long as he is sensible of that disadvantage. Nor is this observable only with regard to characters and manners, but may be remark'd even in the most minute circumstances. A violent cough in another gives us uneasiness; tho' in itself it does not in the least affect us. A man will be mortified, if you tell him he has a stinking breath; tho' 'tis evidently no annoyance to himself. Our fancy easily changes its situation; and either surveying ourselves as we appear to others, or considering others as they feel themselves, wemakes us enter, by that means, into sentiments, which no way belong to us, and in which nothing but sympathy is able to interest us. And this sympathy we sometimes carry so far, as even to be displeas'd with a quality commodious to us, merely because it displeases others, and makesrenders us disagreeable in their eyes; tho' perhaps we never can have any interest in rendering ourselves agreeable to them.
