Famous quotes containing the word mass:

    All great art, and today all great artlessness, must appear extreme to the mass of men, as we know them today. It springs from the anguish of great souls. From the souls of men not formed, but deformed in factories whose inspiration is pelf.
    Alexander Trocchi (1925–1983)

    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)

    ... in the happy laughter of a theatre audience one can get the most immediate and numerically impressive guarantee that there is nothing in one’s mind which is not familiar to the mass of persons living at the time.
