The principal reason which makes our theme appear paradoxical as we maintain it, is the illusion or prejudice that we possess a more complete intuition of reality than we really do. One often hears people say that they have in their minds many important thoughts, but that they are not able to express them. In truth, if they really had them, they would have coined them into beautiful, ringing words, and thus expressed them. If these thoughts seem to vanish or to become scarce and poor in the act of expressing them, either they did not exist or they really were scarce and poor. People think that all of us ordinary men imagine and have intuitions of countries, figures and scenes, like painters; of bodies, like sculptors; save that painters and sculptors know how to paint and to sculpture those images, while we possess them only within our souls. They believe that anyone could have imagined a Madonna of Raphael; but that Raphael was Raphael owing to his technical ability in putting the Madonna upon the canvas. Nothing can be more false than this view. The world of which as a rule we have intuitions, is a small thing. It consists of little expressions which gradually become greater and more ample with the increasing spiritual concentration of certain moments. These are the sort of words which we speak within ourselves, the judgments that we tacitly express: "Here is a man, here is a horse, this is heavy, this is hard, this pleases me," etc. It is a medley of light and colour, which could not pictorially attain to any more sincere expression than a haphazard splash of colours, from among which would with difficulty stand out a few special, distinctive traits. This and nothing else is what we possess in our ordinary life; this is the basis of our ordinary action. It is the index of a book. The labels tied to things take the place of the things themselves. This index and labels (which are themselves expressions) suffice for our small needs and small actions. From time to time we pass from the index to the book, from the label to the thing, or from the slight to the greater intuitions, and from these to the greatest and most lofty. This passage is sometimes far from being easy. It has been observed by those who have best studied the psychology of artists, that when, after having given a rapid glance at anyone, they attempt to obtain a true intuition of him, in order, for example, to paint his portrait, then this ordinary vision, that seemed so precise, so lively, reveals itself as little better than nothing. What remains is found to be at the most some superficial trait, which would not even suffice for a caricature. The person to be painted stands before the artist like a world to discover. Michael Angelo said, "one paints, not with one's hands, but with one's brain." Leonardo shocked the prior of the convent delle Grazie by standing for days together opposite the "Last Supper" without touching it with the brush. He
