Famous quotes containing the words complex and/or classes:
“In ordinary speech the words perception and sensation tend to be used interchangeably, but the psychologist distinguishes. Sensations are the items of consciousness—a color, a weight, a texture—that we tend to think of as simple and single. Perceptions are complex affairs that embrace sensation together with other, associated or revived contents of the mind, including emotions.”
—Jacques Barzun (b. 1907)
“There are two classes of men called poets. The one cultivates life, the other art,... one satisfies hunger, the other gratifies the palate.”
—Henry David Thoreau (1817–1862)
