Famous quotes containing the words occurrences, nature and/or culture:

    “If to be venerated for benevolence, if to be admired for talents, if to be esteemed for patriotism, if to be beloved for philanthropy, can gratify the human mind, you must have the pleasing consolation to know that you have not lived in vain. And I flatter myself that it will not be ranked among the least grateful occurrences of your life to be assured that, so long as I retain my memory, you will be thought on with respect, veneration, and affection by your sincere friend.”
    —George Washington (1732–1799)

    “It is not women’s fault if we are so tender. It is in the nature of the lives we live. And further, it would be a terrible catastrophe if men had to live men’s lives and women’s also. Which is precisely what has happened today—to women.”
    —Selma James (b. 1930)

    “Our culture has become something that is completely and utterly in love with its parent. It’s become a notion of boredom that is bought and sold, where nothing will happen except that people will become more and more terrified of tomorrow, because the new continues to look old, and the old will always look cute.”
    —Malcolm McLaren (b. 1946)
