From “A Personal Odyssey,” my favorite of Thomas Sowell’s books:
My early struggle to make a new life for myself under precarious economic conditions put me in daily contact with people who were neither well-educated nor particularly genteel, but who had practical wisdom far beyond what I had—and I knew it. It gave me a lasting respect for the common sense of ordinary people, a factor routinely ignored by the intellectuals among whom I would later make my career. This was a blind spot in much of their social analysis which I did not have to contend with.
