Famous quotes containing the words fundamental and/or plane:

    “I believe that the fundamental proposition is that we must recognize that the hostilities in Europe, in Africa, and in Asia are all parts of a single world conflict. We must, consequently, recognize that our interests are menaced both in Europe and in the Far East.”
    —Franklin D. Roosevelt (1882–1945)

    “At the moment when a man openly makes known his difference of opinion from a well-known party leader, the whole world thinks that he must be angry with the latter. Sometimes, however, he is just on the point of ceasing to be angry with him. He ventures to put himself on the same plane as his opponent, and is free from the tortures of suppressed envy.”
    —Friedrich Nietzsche (1844–1900)
