Few problems absorb educators as fully as teaching how to think, the most basic of human attributes. in his latest work Marc Belth has taken the mystery out of the thinking process and gone beyond the genetic limitations one finds in the works of Piaget and the Behaviorists. John Walton of John Hopkins University has called this book "a magnum opus." Charles Tesconi, of the University of Illinois, adds: "Belth's manuscript is unique... graduate students in education seldom get beyond a few works in psychology and Dewey's How We Think in dealing with the kinds of questions examined expertly and scholarly by Belth. He is breaking.new ground."
