Famous quotes containing the words physical and/or quantity:
“The author’s conviction on this day of New Year is that music begins to atrophy when it departs too far from the dance; that poetry begins to atrophy when it gets too far from music; but this must not be taken as implying that all good music is dance music or all poetry lyric. Bach and Mozart are never too far from physical movement.”
—Ezra Pound (1885–1972)
“Something is infinite if, taking it quantity by quantity, we can always take something outside.”
—Aristotle (384–322 B.C.)
