### Famous quotes containing the words fraction and/or mass:

“The visual is sorely undervalued in modern scholarship. Art history has attained only a *fraction* of the conceptual sophistication of literary criticism.... Drunk with self-love, criticism has hugely overestimated the centrality of language to western culture. It has failed to see the electrifying sign language of images.”

—Camille Paglia (b. 1947)

“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)
