• Synonyms and Candid, Fair, Open, Frank, Ingenuous, Naïve, Sincere, unprejudiced, unbiased. The first seven words apply to the spirit, expression, or manner. The candid man is able to look impartially on both sides of a subject, especially giving due weight to arguments or opinions opposed to his own, and due credit to the motives of opponents; candid speech is essentially the same as frank speech, sometimes going so far as to be blunt. Fair belongs primarily to conduct, but in regard to speech and thought it is the same as candid: as, a man preëminently fair in dealing with opposing views. Open is opposed to concealment; the open man does not cultivate a politic reserve, but expresses his opinions freely, without stopping to think of their effect upon his own interests. Frank, literally, free; the freedom may be in regard to one's own opinions, which is the same as openness, or in regard to things belonging to others, where the freedom may go so far as to be unpleasant, or it may disregard conventional ideas as to reticence. Hence, while openness Is consistent with timidity, frankness implies some degree of boldness. Ingenuous implies a permanent moral quality, an elevated inability to be other than honest or open, even to one's own loss; there is a peculiar subjective cast to the word, as though the man stood most in awe of the disapprobation of his own judgment and conscience; hence the close connection between ingenuousness and modesty. Naive expresses a real or an assumed unconsciousness of the way in which one's words meet conventional rules, or of the construction which may be put upon them by others; naïveté is thus an openness or frankness proceeding from native or assumed simplicity or artlessness. Sincere expresses the spirit and language that go with the love of truth; the sincere man is necessarily candid and fair, and as open and frank as seems required by truth.
