Famous quotes containing the word heart:
“I have the heart of a man, not a woman, and I am not afraid of anything.”
—Elizabeth I (1533–1603)
“Anarchism is the only philosophy which brings man the consciousness of himself; which maintains that God, the State, and society are non-existent, that their promises are null and void, since they can be fulfilled only through man’s subordination.... The individual is the heart of society, conserving the essence of social life; society is the lungs which are distributing the element to keep the life essence—that, is, the individual—pure and strong.”
—Emma Goldman (1869–1940)
