Famous quotes containing the word dominant:
“Combativeness was, I suppose, the dominant trait in my grandmother’s nature. An aggressive churchgoer, she was quite without Christian feeling; the mercy of the Lord Jesus had never entered her heart. Her piety was an act of war against Protestant ascendancy. ...The teachings of the Church did not interest her, except as they were a rebuke to others ...”
—Mary McCarthy (1912–1989)
