“A pine tree standeth lonelyIn the North on an upland bare;It standeth whitely shroudedWith snow, and sleepeth there.It dreameth of a Palm treeWhich far in the East alone,In the mournful silence standethOn its ridge of burning stone.”

“Where they have burned books, they will end in burning human beings.”

“There, where one burns books, one in the end burns men.”

“All I really want is enough to live on, a little house in the country... and a tree in the garden with seven of my enemies hanging in it. ”

“The history of Immanuel Kant's life is difficult to portray, for he had neither life nor history. He led a mechanical, regular, almost abstract bachelor existence in a little retired street of Königsberg, an old town on the north-eastern frontier of Germany. I do not believe that the great clock of the cathedral performed in a more passionless and methodical manner its daily routine than did its townsman, Immanuel Kant. Rising in the morning, coffee-drinking, writing, reading lectures, dining, walking, everything had its appointed time, and the neighbors knew that it was exactly half-past three o'clock when Kant stepped forth from his house in his grey, tight-fitting coat, with his Spanish cane in his hand, and betook himself to the little linden avenue called after him to this day the "Philosopher's Walk." Summer and winter he walked up and down it eight times, and when the weather was dull or heavy clouds prognosticated rain, the townspeople beheld his servant, the old Lampe, trudging anxiously behind Kant with a big umbrella under his arm, like an image of Providence.What a strange contrast did this man's outward life present to his destructive, world-annihilating thoughts! In sooth, had the citizens of Königsberg had the least presentiment of the full significance of his ideas, they would have felt far more awful dread at the presence of this man than at the sight of an executioner, who can but kill the body. But the worthy folk saw in him nothing more than a Professor of Philosophy, and as he passed at his customary hour, they greeted him in a friendly manner and set their watches by him.”

“Mine is a most peaceable disposition. My wishes are: a humble cottage with a thatched roof, but a good bed, good food, the freshest milk and butter, flowers before my window, and a few fine trees before my door; and if God wants to make my happiness complete, he will grant me the joy of seeing some six or seven of my enemies hanging from those trees. Before death I shall, moved in my heart, forgive them all the wrong they did me in their lifetime. One must, it is true, forgive one's enemies-- but not before they have been hanged.”

“The stones here speak to me, and I know their mute language. Also, they seem deeply to feel what I think. So a broken column of the old Roman times, an old tower of Lombardy, a weather-beaten Gothic piece of a pillar understands me well. But I am a ruin myself, wandering among ruins.”
