Famous quotes containing the words daylight, intensity and/or conditions:
“Quidquid luce fuit tenebris agit: but also the other way around. What we experience in dreams, so long as we experience it frequently, is in the end just as much a part of the total economy of our soul as anything we “really” experience: because of it we are richer or poorer, are sensitive to one need more or less, and are eventually guided a little by our dream-habits in broad daylight and even in the most cheerful moments occupying our waking spirit.”
—Friedrich Nietzsche (1844–1900)
“Murder is born of love, and love attains the greatest intensity in murder.”
—Octave Mirbeau (1850–1917)
“Any man who does not accept the conditions of life sells his soul.”
—Charles Baudelaire (1821–1867)
