It is on the question of detail and the careful anxiety concerning the surface that the art instinct avoids science, refusing her microscope in preference for the unaided impression of normal sight. The living art of the ages is that in which the painter is seen to be greater than his theme, in which we acknowledge the power first, and afterward the product. It is the unfettered mode allowing the greatest individualism of expression; it is, in short, the man end of it which lives, for his is the immortal life.
The argument of the book is here reduced to a working basis.
The first point settled in the making of a picture after the subject has germinated, is the shape into which the items of the concept are to be edited; the second is the arrangement of those items within the proscribed limits; the third is the defining of the dark and light masses. This consideration forces the question whence the light, together with its answer, hence the shadow.
The detail of the direction of light and the action of the shadows cuts the pictorial intention clear of the decorative design. Design is a good basis, its simplicity yielding favorably to the settlement of spaces and the construction of lines, but its chief purpose ends when it has cleared the field of little things and reduced the first conception, which usually comes as a bundle of items, to a broad and dignified foundation into which these little things are set.
A severe, space-filling design in three tones or four will place the student in a position of confidence to proceed with detail which, until the design has settled well into its four sides, should be persistently excluded. It may, however, be found that the _essence_ of certain subjects lies in a small item of detail. This, when known, must be allowed for in the design.
Of first importance in composition is the notion of Light and Dark, to which Line is second. In the tone design line is but the edge of the masses. Line as the basis of the form of the design is reduced to a few forms which with modifications become the framework for all pictorial structure. (See _Fundamental Forms._) Line as an element of beauty sufficient of itself to become subjective is rare, an exception in pictorial art. (See _Line_)
