The deeper causes for this widespread lack of literary appreciation among the people, and even among teachers and scholars, is found partly in the practical, scientific, and utilitarian spirit of the age, and partly in the corresponding unliterary courses of study which have prevailed everywhere in our common schools. The absence of literary standards and taste among teachers is due largely to the failure of the schools themselves, hitherto, to cultivate this sort of proficiency. Those very qualities which give to literature its supreme excellence, its poetic beauty, its artistic finish and idealism, are among the highest fruits of culture, and are far more difficult of attainment than mere knowledge. It is no small thing to introduce the rarest and finest culture of the world into the common school, and thus propagate, in the broadest democratic fashion, that which is the peculiar, superior refinement of the choicest spirits of the world. If progress in this direction is slow, we may remember that the best ideals are slow of attainment. There is also an intangible quality in all first-class literature, which is not capable of exact description or demonstration. George Willis Cooke, in "Poets and Problems" (pp. 31-32), says:-- "Poetry enters into those higher regions of human experience concerning which no definite account can be given; where all words fail; about which all we know is to be obtained by hints, symbols, poetic figures, and imagings. Poetry is truer and more helpful than prose, because it penetrates those regions of feeling, beauty, and spiritual reality, where definitions have no place or justification. There would be no poetry if life were limited to what we can understand; nor would there be any religion. Indeed, the joy, the beauty, and the promise of life would all be gone if there were nothing which reaches beyond our powers of definition. The mystery of existence makes the grandeur and worth of man's nature, as it makes for him his poetry and his religion. Poetry suggests, hints, images forth, what is too wonderful, too transcendent, too near primal reality, too full of life, beauty, and joy, for explanation or comprehension. It embodies man's longing after the Eternal One, expresses his sense of the deep mystery of Being, voices his soul sorrow, illumines his path with hope and objects of beauty. Man's aspiration, his sense of imperfection, his yearning for a sustaining truth and reality, as the life within and over all things, find expression in poetry; because it offers the fittest medium of interpretation for these higher movements of soul. Whenever the soul feels deeply, or is stirred by a great thought, the poetic form of utterance at once becomes the most natural and desirable for its loving and faithful interpretation."
