Famous quotes containing the words acceptance and/or angle:

    “Cynicism makes things worse than they are in that it makes permanent the current condition, leaving us with no hope of transcending it. Idealism refuses to confront reality as it is but overlays it with sentimentality. What cynicism and idealism share in common is an acceptance of reality as it is but with a bad conscience.”
    —Richard Stivers, U.S. sociologist, educator. The Culture of Cynicism: American Morality in Decline, ch. 1, Blackwell (1994)

    “From whichever angle one looks at it, the application of racial theories remains a striking proof of the lowered demands of public opinion upon the purity of critical judgment.”
    —Johan Huizinga (1872–1945)
