Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.

Who knows for what we live, and struggle, and die? Wise men write many books, in words too hard to understand. But this, the purpose of our lives, the end of all our struggle, is beyond all human wisdom.

Great wisdom is generous petty wisdom is contentious. Great speech is impassioned, small speech cantankerous.
