"I should say that the most prominent scientific men of our country, and perhaps of this age, are either serving the arts and not pure science, or are performing faithful but quite subordinate labors in particular departments. They make no steady and systematic approaches to the central fact.... There is wanting constant and accurate observation with enough of theory to direct and discipline it. But, above all, there is wanting genius."
"Art can never match the luxury and superfluity of Nature. In the former all is seen; it cannot afford concealed wealth, and is niggardly in comparison; but Nature, even when she is scant and thin outwardly, satisfies us still by the assurance of a certain generosity at the roots."
"It required some rudeness to disturb with our boat the mirror-like surface of the water, in which every twig and blade of grass was so faithfully reflected; too faithfully indeed for art to imitate, for only Nature may exaggerate herself."
"In the wildest nature, there is not only the material of the most cultivated life, and a sort of anticipation of the last result,but a greater refinement already than is ever attained by man.... Nature is prepared to welcome into her scenery the finest work of human art, for she is herself an art so cunning that the artist never appears in his work."
"The true poem is not that which the public read. There is always a poem not printed on paper,... in the poet's life. It is what hehas become through his work. Not how is the idea expressed in stone, or on canvas or paper, is the question, but how far it has obtained form and expression in the life of the artist. His true work will not stand in any prince's gallery."
"There is a continual exchange of ideas between all minds of a generation. Journalists, popular novelists, illustrators, and cartoonists adapt the truths discovered by the powerful intellects for the multitude. It is like a spiritual flood, like a gush that pours into multiple cascades until it forms the great moving sheet of water that stands for the mentality of a period."
"Only conservatives believe that subversion is still being carried on in the arts and that society is being shaken by it.... Advanced art today is no longer a cause--it contains no moral imperative. There is no virtue in clinging to principles and standards, no vice in selling or in selling out."
"Not even the visionary or mystical experience ever lasts very long. It is for art to capture that experience, to offer it to, in the case of literature, its readers; to be, for a secular, materialist culture, some sort of replacement for what the love of god offers in the world of faith."
"He who has learned what is commonly considered the whole art of painting, that is, the art of representing any natural object faithfully, has as yet only learned the language by which his thoughts are to be expressed."
