The aspect of the impudent wrongness is pleasurable to vulgar persons, and is what they commonly call "free" execution; the timid, tottering, hesitating wrongness is rarely so attractive; yet sometimes, if accompanied with good qualities, and right aims in other directions, it becomes in a manner charming, like the inarticulateness of a child; but, whatever the charm or manner of the error, there is but one question ultimately to be asked respecting every line you draw, Is it right or wrong?
