Martin Lewis is a strong believer in comprehensive frameworks of knowledge about the world, which he seeks to develop and convey in his writing and teaching. By the same token, loathes the pervasive indifference to knowledge that characterizes the American educational establishment. His intellectual heroes are Abu Rayhan al-Biruni (973–1050) and Alexander von Humboldt (1769–1859), and his anti-hero is John Dewey (1859–1952).

Martin lives with his wife of forty years, Kären Wigen, on the Stanford Campus, near Palo Alto, California. They have two adult children and two young granddaughters, who they visit as often as possible. He spends much of his time at his family’s rural property in Mendocino County, California, where he gardens and helps manage the land. In his personal view, a fulfilling life must involve a balance of intellectual and physical labor.
