"Plants are Children of the Earth; we are Children of the Æther. Our Lungs are properly our Root; we live, when we breathe; we begin our life with breathing."

“Many counterrevolutionary books have been written in favor of the Revolution. But Burke has written a revolutionary book against the Revolution.”

“Goethe is an altogether practical Poet. He is in his works what the English are in their wares: highly simple, neat, convenient and durable. He has done in German Literature what Wedgwood did in English Manufacture. He has, like the English, a natural turn for Economy, and a noble Taste acquired by Understanding. Both these are very compatible, and have a near affinity in the chemical sense.”

“We are on a mission: we are called to the cultivation of the earth.”
