If I can get you to laugh with me, you like me better, which makes you more open to my ideas. And if I can persuade you to laugh at the particular point I make, by laughing at it you acknowledge its truth.
I value unity because I believe we learn truth from each other in this process.
That which you create in beauty and goodness and truth lives on for all time to come. Don’t spend your life accumulating material objects that will only turn to dust and ashes.
