Especially when there is a lot of political rhetoric in the air, those of us with strong political convictions are inclined to reflect on just why we hold certain views even as others who are basically like us hold very different ones. Social scientists and other thinkers struggle to explain it, but the puzzle remains—in part because they, too, disagree so much with one another. Whether the arena is politics, religion, business, scientific research, or education, individuals who operate in the same environment and experience the same conditions may have radically different interpretations of the facts and diametrically opposed convictions about how to react to them. When faced with a fundamental disagreement, we ask ourselves: Why are these folks so wrong? And how can they be so convinced that we are wrong? In this provocative monograph, Tibor Machan explores the principles of truth, reason, and ideology, with particular respect to the profound political, economic, and social crises gripping the world today. In so doing, he not only sheds light on the nature of “truth” but also suggests a framework for embracing differences to come up with creative solutions.
