Sec. 21. This method of study, being peculiarly characteristic of the Roman and Florentine schools, and associated with very accurate knowledge of form and expression, has gradually got to be thought by a large body of artists the _grand_ way of study; an idea which has been fostered all the more because it was an unnatural way, and therefore thought to be a philosophical one. Almost the first idea of a child, or of a simple person looking at anything, is, that it is a red, or a black, or a green, or a white thing. Nay, say the artists; that is an unphilosophical and barbarous view of the matter. Red and white are mere vulgar appearances; look farther into the matter, and you will see such and such wonderful other appearances. Abstract those, _they_ are the heroic, epic, historic, and generally eligible appearances. And acting on this grand principle, they draw flesh white, leaves white, ground white, everything white in the light, and everything black in the shade--and think themselves wise. But, the longer I live, the more ground I see to hold in high honor a certain sort of childishness or innocent susceptibility. Generally speaking, I find that when we first look at a subject, we get a glimpse of some of the greatest truths about it: as we look longer, our vanity, and false reasoning, and half-knowledge, lead us into various wrong opinions; but as we look longer still, we gradually return to our first impressions, only with a full understanding of their mystical and innermost reasons; and of much beyond and beside them, not then known to us, now added (partly as a foundation, partly as a corollary) to what at first we felt or saw. It is thus eminently in this matter of color. Lay your hand over the page of this book,--any child or simple person looking at the hand and book, would perceive, as the main fact of the matter, that a brownish pink thing was laid over a white one. The grand artist comes and tells you that your hand is not pink, and your paper is not white. He shades your fingers and shades your book, and makes you see all manner of starting veins, and projecting muscles, and black hollows, where before you saw nothing but paper and fingers. But go a little farther, and you will get more innocent again; you will find that, when "science has done its worst, two and two still make four;" and that the main and most important facts about your hand, so seen, are, after all, that it has four fingers and a thumb--showing as brownish pink things on white paper.
