From the very moment philosophy was born, thought and walking have been inseparable. For thinkers across the ages, walking was never merely a means of getting from one place to another — it was a method of thought itself.
Trace their habits, and something essential about the workings of the mind comes into view. In this first installment, we follow the footsteps of three thinkers who laid the foundations of Western philosophy, from ancient Greece to eighteenth-century Europe.
Aristotle and the Peripatetic School
The ancient Greek philosopher Aristotle is said to have lectured his students while walking the covered walkways of the Lyceum. His school came to be known as the "Peripatetic school," a name drawn from the Greek word peripatein, meaning "to walk about" — a direct reference to this habit of debating while in motion.
Rather than sitting and lecturing one-directionally, he exchanged questions with his students as they walked together. The steady rhythm of footsteps loosened the mind, and walking side by side with a conversation partner created a relationship of equals rather than one of hierarchy. At the very starting point of Western philosophy, walking was already there.
Rousseau and the Reveries of a Solitary Walker
The eighteenth-century French thinker Jean-Jacques Rousseau wrote in his Confessions: "I can only meditate when I am walking; when I stop, I cease to think; my mind only works with my legs. The countryside is my study. The sight of a desk and paper is unbearable to me; the mere preparation for work discourages me from doing it. If I sit down to write, I find I have nothing left to say. Trying to force my thoughts only steals them away from me."
For Rousseau, the very posture of sitting at a desk seemed to smother thought itself. He kept walking — through Paris, Geneva, Môtiers, and England — pursued always by persecution and controversy, and in his later years he grew absorbed in botany, wandering alone through the outskirts of Paris to observe wildflowers and grasses.
Begun two years before his death and left unfinished, the Reveries of a Solitary Walker is, true to its title, a collection of reflections he composed while walking alone. Few thinkers have put into words, so plainly, the sense of thought and walking moving in step with one another.
Kant's Clockwork Walks
The German philosopher Immanuel Kant was known for taking the same walk, along the same route, at precisely the same hour every day — so reliably that, according to legend, the residents of Königsberg would set their clocks by the moment he passed. He never skipped his walk, rain or snow, and his servant Lampe is said to have followed a few steps behind, carrying a large umbrella.
Kant himself was never a robust man — small in stature, narrow-chested, frail from birth. Perhaps precisely because of this, he maintained his health by adhering strictly to a regular routine: rising at five in the morning, writing, lecturing, a single daily meal accompanied by long conversation, and then his walk. That he lived to nearly eighty was, for his era, a remarkable feat of longevity.
Kant's days — which produced the towering achievement of modern philosophy that is the Critique of Pure Reason — were structured with precision around time spent at his desk and time spent walking the streets of his city. For him, walking was a ritual by which thought was ordered and deepened.
Walking Was Thinking
Aristotle, conversing along the colonnades. Rousseau, wandering the hills and fields. Kant, walking the same path at the same hour, day after day. The three walked in entirely different ways. And yet what they shared was this: none of them treated walking as mere diversion. Each understood it as an act of thinking itself.
This disposition, carried forward across more than two thousand years, would take on a wilder, more hands-on form as the nineteenth century began. The next generation of walkers would leave their studies behind, stepping out into forests, mountains, and gardens.
