Arthur Schopenhauer,
The Metaphysics of Fine Art
“ But, in spite of this difference of method between Science and Art, there is some similarity in their treatment of single facts. For just as the botanist picks a single flower from the boundless realm of the vegetable world, and then takes it to pieces in order to demonstrate, from the single specimen, the nature of the plant itself; so the poet chooses out of the endless turmoil of human life as it hurries incessantly on its way, some one scene, nay, often only some one mood, some one sensation, so that he may show us from it what is the life and character of man. ”
