How to conquer stupidity

Leo Markun's bracing, provocative case that dull thinking is a habit we can break. He examines the everyday laziness, prejudice, and muddle that pass for thought and argues that clearer, sharper reasoning is open to anyone willing to work at it. Blunt and often funny, it is a challenge as much as a guide. A stimulating read for anyone who suspects they could be using their mind rather better than they do.
