This reissue of Thomas Sowell’s classic study of decision making, which includes a preface by the author, updates his seminal work in the context of The Vision of the Anointed. Sowell, one of America’s most celebrated public intellectuals, describes in concrete detail how knowledge is shared and disseminated throughout modern society. He warns that society suffers from an ever-widening gap between firsthand knowledge and decision making—a gap that threatens not only our economic and political efficiency but our very freedom.

Alexander von Humboldt (1769-1859) is the great lost scientist: more things are named after him than anyone else.

His colourful adventures read like something out of a Boy's Own story.

What he found is that more and more people all over the world have begun to recognize three startling truths: Drugs are not what we think they are. Addiction is not what we think it is. And the drug war has very different motives to the ones we have seen on our TV screens for so long.
