Famous quotes containing the words perennial and/or sunflower:
“There is no arguing with the pretenders to a divine knowledge and to a divine mission. They are possessed with the sin of pride, they have yielded to the perennial temptation.”
—Walter Lippmann (1889–1974)
“When van Gogh paints sunflowers, he reveals, or achieves, the vivid relation between himself, as man, and the sunflower, as sunflower, at that quick moment of time. His painting does not represent the sunflower itself. We shall never know what the sunflower itself is. And the camera will visualize the sunflower far more perfectly than van Gogh can.”
—D.H. (David Herbert)
