Famous quotes containing the words physical and/or quantity:
“To many women marriage is only this. It is merely a physical change impinging on their ordinary nature, leaving their mentality untouched, their self-possession intact. They are not burnt by even the red fire of physical passion—far less by the white fire of love.”
—Mary Webb (1881–1927)
“... nothing is more human than substituting the quantity of words and actions for their character. But using imprecise words is very similar to using lots of words, for the more imprecise a word is, the greater the area it covers.”
—Robert Musil (1880–1942)
