Delta Wave Activity

Famous quotes containing the words wave and/or activity:

“The history of any nation follows an undulatory course. In the trough of the wave we find more or less complete anarchy; but the crest is not more or less complete Utopia, but only, at best, a tolerably humane, partially free and fairly just society that invariably carries within itself the seeds of its own decadence.”
—Aldous Huxley (1894–1963)

“For art to exist, for any sort of aesthetic activity or perception to exist, a certain physiological precondition is indispensable: rapture.”
—Friedrich Nietzsche (1844–1900)
