Famous quotes containing the word mass:
“I stand for the heart. To the dogs with the head! I had rather be a fool with a heart, than Jupiter Olympus with his head. The reason the mass of men fear God, and at bottom dislike Him, is because they rather distrust His heart, and fancy Him all brain like a watch.”
—Herman Melville (1819–1891)
“I am not a very sentimental man; and the best sentiment I can think of is, that if you collect the signatures of all persons who are no less distinguished than I, you will have a very undistinguishing mass of names.”
—Abraham Lincoln (1809–1865)
“Like Freud, Jung believes that the human mind contains archaic remnants, residues of the long history and evolution of mankind. In the unconscious, primordial “universally human images” lie dormant. Those primordial images are the most ancient, universal and “deep” thoughts of mankind. Since they embody feelings as much as thought, they are properly “thought feelings.” Where Freud postulates a mass psyche, Jung postulates a collective psyche.”
—Patrick Mullahy (b. 1912)
