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.

Context

“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, accomplished 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 remarked even in the most minute circumstances. A violent cough in another gives us uneasiness; though in itself it does not in the least affect us.” source
