Controversies in politics arise from many sources, but the conlficts that endure for generations or centuries show a remarkably consistent pattern.
In this book, which the author calls a “culmination of thirty years of work in the history of ideas,” Sowell attempts to explain the ideological difference between liberals and conservatives as a disagreement over the moral potential inherent in nature. Those who see that potential as limited prefer to constrain governmental authority, he argues. They feel that reform is difficult and often dangerous, and they put their faith in family, custom, law, and traditional institutions. Conversely, those who have faith in human nature prefer to remove institutional and traditional constraints. Controversies over such diverse issues as criminal justice, income distribution, or war and peace repeatedly show an ideological divide along the lines of these two conflicting visions.
Great book, get the hard copy. This guy and his monotone will put you to sleep.
Sowell articulates the two antithetical visions with their respective assumptions and implications in a way that leads one to say, "Now I get it".
Beyond a Red vs Blue book
He really makes his case quite early in the book that there is a conflict of visions between those who see man as basically flawed and those who believe man and society can be perfected. He then argues the irrational fantasy of utopians. I great book by great thinker.
