Famous quotes containing the words involved and/or drive:
“Whilst Marx turned the Hegelian dialectic outwards, making it an instrument with which he could interpret the facts of history and so arrive at an objective science which insists on the translation of theory into action, Kierkegaard, on the other hand, turned the same instruments inwards, for the examination of his own soul or psychology, arriving at a subjective philosophy which involved him in the deepest pessimism and despair of action.”
—Sir Herbert Read (1893–1968)
“...I don’t have an inner drive to do as well as anybody else ... I have a great pleasure in writing and part of that is political and part of that is I’m surprised that I’ve done as well as I have. I really am just surprised.”
—Grace Paley (b. 1922)
