No matter. Adler's greatest pleasure is in reaching ordinary people, prodding what he believes to be the innate desire to learn. Proudly, he shows a recent letter from David Call, a journeyman plumber in Utah: "I am writing on behalf of a group of construction workers (mostly plumbers!)," notes Call, "who have finally found a teacher worth listening to. We have been studying your books for over a year now and have put together a sizable library of your writings. We may be plumbers during the day, but at lunch time and at night and on weekends, we are philosophers at large." Beams Adler, whose 1977 autobiography was proudly titled Philosopher at Large: "I've finally lived long enough to have a general audience."
