Famous quotes containing the words standard and/or atmosphere:

    “As long as male behavior is taken to be the norm, there can be no serious questioning of male traits and behavior. A norm is by definition a standard for judging; it is not itself subject to judgment.”
    —Myriam Miedzian, U.S. author. Boys Will Be Boys, ch. 1 (1991)

    “We must be generously willing to leave for a time the narrow boundaries in which our individual lives are passed ... In this fresh, breezy atmosphere ... we will be surprised to find that many of our familiar old conventional truths look very queer indeed in some of the sudden side lights thrown upon them.”
    —Bertha Honore Potter Palmer (1849–1918)
