"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."
