Context

“If I thought myself perfectly good and wise, I would rattle it out to some purpose. To speak less of one’s self than what one really is is folly, not modesty; and to take that for current pay which is under a man’s value is pusillanimity and cowardice, according to, Aristotle. No virtue assists itself with falsehood; truth is never matter of error. To speak more of one’s self than is really true is not always mere presumption; ‘tis, moreover, very often folly; to, be immeasurably pleased with what one is, and to fall into an indiscreet self-love, is in my opinion the substance of this vice.” source
