Fun I love, but too much fun is of all things the most loathsome. Mirth is better than fun, and happiness is better than mirth.
And what is happy? It is a going always on. There is something better to be done than I have done, and spurred by the fair delusion of progress, I will seek to progress, to whip myself on, to more and more – to learning. Always.
All rationalism tends to minimalise the value and the importance of life and to decrease the sum total of human happiness.
