"What is Nature? An encyclopedical, systematic Index or Plan of our Spirit. Why will we content us with the mere catalogue of our Treasures? Let us contemplate them ourselves, and in all ways elaborate and use them."

“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.”

“Life is a disease of the spirit; a working incited by Passion. Rest is peculiar to the spirit.”

“Now to Some it appears not at all worth while to follow out the endless divisions of Nature; and moreover a dangerous undertaking, without fruit and issue. As we can never reach, say they, the absolutely smallest grain of material bodies, never find their simplest compartments, since all magnitude loses itself, forwards and backwards, in infinitude; so likewise is it with the species of bodies and powers; here too one comes on new species, new combinations, new appearances, even to infinitude. These seem only to stop, continue they, when our diligence tires; and so it is spending precious time with idle contemplations and tedious enumerations; and this becomes at last a true delirium, a real vertigo over the horrid Deep”

“Sleep is for the inhabitants of Planets only. In another time, Man will sleep and wake continually at once. The greater part of our Body, of our Humanity itself, yet sleeps a deep sleep.”
