--Compact Oxford English Dictionary
"In perpetual motion" is a good equivalent of what we mean by "peripatetic," which ultimately derives from the Greek by peripatos, a courtyard for walking about, and more directly from peripatetikos "given to walking about" (not "given to jogging about"). This unwieldy and somewhat pretentious adjective would never have entered the Language but for one very famous peripatetic philosopher: Aristole. As the story goes, Aristotle was fond of pacing about in the peripatos at his Lyceum [lecture hall], a habit he passed on to later deep thinkers. His system of thought came to be named after this practice, and thus was born the Peripatetic School of philosophy.
All the early uses of "peripatetic" in English refter to Aristotle's teachings, but its potential as a humorous metaphor became obvious by the late sixteenth century. John Moore applied the term with gusto in 1617: "The devil is a Peripatetic . . . always walking and going about, seeking whom he may ensnare" (103).
