Life in its entire compass is regarded as the rough material of literature, but it does not become literature until the artist's imagination, as with a divine ray, has penetrated the mass and inspired it with an ideal existence. Among the numerous attempts of his contemporaries to define the creative faculty of the poet, this comparatively simple one of Hazlitt's is worth noting. "This intuitive perception of the hidden analogies of things, or, as it may be called, this _instinct of imagination_, is perhaps what stamps the character of genius on the productions of art more than any other circumstance: for it works unconsciously, like nature, and receives its impressions from a kind of inspiration."[72] It is this power that he has in mind when he says "Poetry is infusing the same spirit in a number of things, or bathing them all as it were, in the same overflowing sense of delight."[73] It shows Hazlitt to have fully apprehended the guiding principle of the new ideal of criticism which, looking upon the work of art as an act of original creation and not of mechanical composition, based its judgment on a direct sympathy with the artist's mind instead of resorting to a general rule. In the light of this principle he is enabled to avoid the pitfalls of a moralistic interpretation of literature and to decide the question as to the relative importance of substance and treatment with a certainty which seems to preclude the possibility of any other answer. It is not the dignity of the theme which constitutes the great work of art, for in that case a prose summary of the "Divine Comedy" would be as exalted as the original, and it would be necessary merely to know the subject of a poem in order to pass judgment upon it. A low or a trivial subject may be raised by the imagination of the artist who recognizes in it the elements of beauty or power. No definition of poetry can be worth anything which would exclude "The Rape of the Lock"; and Murillo's painting of "The Two Beggar Boys" is as much worth having "as almost any picture in the world."[74] "Yet it is not true that execution is everything, and the class or subject nothing. The highest subjects, equally well-executed (which, however, rarely happens), are the best."[75] Though each is perfect in its kind, there can be no difficulty in deciding the question of greatness between "King Lear" and "The Comedy of Errors." "The greatest strength of genius is shewn in describing the strongest passions: for the power of imagination, in works of invention, must be in proportion to the force of the natural impressions, which are the subject of them."[76] One also finds a test of relative values in the measure of fulness with which the work of art reflects the complex elements of life. If we estimate a tragedy of Shakespeare above one of Lillo or Moore, it is because "impassioned poetry is an emanation of the moral and intellectual part of our nature, as well as of the sensitive--of the desire to know,
