Famous quotes containing the words sense, plan and/or act:

    “The confusion is not my invention. We cannot listen to a conversation for five minutes without being aware of the confusion. It is all around us and our only chance now is to let it in. The only chance of renovation is to open our eyes and see the mess. It is not a mess you can make sense of.”
    —Samuel Beckett (1906–1989)

    “Tired minds don’t plan well. Sleep first, plan later.”
    —Walter Reisch (1903–1963)

    “No legislation can suppress nature; all life rushes to reproduction; our procreative faculties are matured early, while passion is strong, and judgment and self-restraint weak. We cannot alter this, but we can alter what is conventional. We can refuse to brand an act of nature as a crime, and to impute to vice what is due to ignorance.”
    —Tennessee Claflin (1846–1923)
