Context

“(I may as well confess it, since my denial of it will be believed by nobody) , perhaps I shall a good deal gratify my own vanity. [4] Indeed, I scarce ever heard or saw the introductory words, "Without vanity I may say," etc., but some vain thing immediately followed. Most people dislike vanity in others, whatever share they have of it themselves; but I give it fair quarter wherever I meet with it, being persuaded that it is often productive of good to the possessor, and to others that are within his sphere of action; and therefore, in many cases, it would not be altogether absurd if a man were to thank God for his vanity among the other comforts of life.” source
