Adolescence is a relatively recent thing in human history -- a period of years between the constraints of childhood and the responsibilities of adulthood. This irresponsible period of adolescence is artificially extended by long years of education, much of it wasted on frivolities. Tenure extends adolescence even further for teachers and professors.

When a highly successful leader retires after a long career, it is very unlikely that his successor will be of comparable caliber. Anyone of similar ability and drive would have gone somewhere else, instead of waiting in the wings for years for a chance to show his own leadership.

Why the transfer of decisions from those with personal experience and a stake in the outcome to those with neither can be expected to lead to better decisions is a question seldom asked, much less answered.

If one writing contributed more than any other to the framework in which this work Sowell's Knowledge and Decisions developed, it would be an essay entitled 'The Use of Knowledge in Society,' published in the American Economic Review of September 1945, and written by F.

Even the Soviet Union, with its huge nuclear arsenal, was a threat that could be deterred by the prospect of retaliation. But suicide bombers cannot be deterred. They can only be annihilated - preemptively and unilaterally, if necessary.

The gun-control crusade today is like the Prohibition crusade 100 years ago. It is a shared zealotry that binds the self-righteous know-it-alls in a warm fellowship of those who see themselves as fighting on the side of the angels against the forces of evil. It is a lofty role that they are not about to give up for anything so mundane as facts - or even the lives of other people.
