"Gravitation is not responsible for people falling in love."
"He who can no longer pause to wonder and stand rapt in awe, is as good as dead; his eyes are closed."
"He who joyfully marches to music in rank and file has already earned my contempt. He has been given a large brain by mistake, since for him the spinal cord would suffice."

"People love chopping wood. In this activity one immediately sees results."
