T 2.2.1.9

There are few persons, that are satisfy'd with their own character, or genius, or fortune, who are not desirous of shewing themselves to the world, and of acquiring the love |and approbation of mankind. Now 'tis evident, that the very same qualities and circumstances, which are the causes of pride or self-esteem, are also the causes of vanity or the desire of reputation; and that we always put to view those particulars with which in ourselves we are best satisfy'd. But if love and esteem were not produc'd by the same qualities as pride, according as these qualities are related to ourselves or others, this method of proceeding wou'd be very absurd, nor cou'd men expect a correspondence in the sentiments of every other person, with those themselves have entertain'd. 'Tis true, few can form exact systems of the passions, or make reflections on their general nature and resemblances. But without such a progress in philosophy, we are not subject to many mistakes in this particular, but are sufficiently guided by common experience, as well as by a kind of presensation; which tells us what will operate on others, by what we feel immediately in ourselves. Since then the same qualities that produce pride or humility, cause love or hatred; all the arguments that have been employ'd to prove, that the causes of the former passions excite a pain or pleasure independent of the passion, will be applicable with equal evidence to the causes of the latter.
