Famous quotes containing the words fill and/or factor:
“Let no one think that I do not love the old ministers. They were, probably, the best men in their generation, and they deserve that their biographies should fill the pages of the town histories. If I could but hear the “glad tidings” of which they tell, and which, perchance, they heard, I might write in a worthier strain than this.”
—Henry David Thoreau (1817–1862)
“In his very rejection of art Walt Whitman is an artist. He tried to produce a certain effect by certain means and he succeeded.... He stands apart, and the chief value of his work is in its prophecy, not in its performance. He has begun a prelude to larger themes. He is the herald to a new era. As a man he is the precursor of a fresh type. He is a factor in the heroic and spiritual evolution of the human being. If Poetry has passed him by, Philosophy will take note of him.”
—Oscar Wilde (1854–1900)
