Mathematics Has The Completely False Reputation Of Yielding Infallible Conclusions. Its Infallibility Is Nothing But Identity. Two Times Two Is Not Four, But It Is Just Two Times Two, And That Is What We Call Four For Short. But Four Is Nothing New At All.

The Flowers Of Life Are But Visionary. How Many Pass Away And Leave No Trace Behind! How Few Yield Any Fruit,--and The Fruit Itself, How Rarely Does It Ripen!

I Believe In God And In Nature And In The Triumph Of Good Over Evil.

Happy The Man Who Early Learns The Wide Chasm That Lies Between His Wishes And His Powers.
