Physical Knowledge

Famous quotes containing the words physical and/or knowledge:

“Authority is not a quality one person “has,” in the sense that he has property or physical qualities. Authority refers to an interpersonal relation in which one person looks upon another as somebody superior to him.”
—Erich Fromm (1900–1980)

“What we know is not capable of being otherwise; of things capable of being otherwise we do not know, when they have passed outside our observation, whether they exist or not. Therefore the object of knowledge is of necessity. Therefore it is eternal; for things that are of necessity in the unqualified sense are all eternal; and things that are eternal are ungenerated and imperishable.”
—Aristotle (384–323 B.C.)
