One of the most powerful lenses through which to view the transformation from Character to Personality is the self-help tradition in which Dale Carnegie played such a prominent role. Self-help books have always loomed large in the American psyche. Many of the earliest conduct guides were religious parables, like The Pilgrim’s Progress, published in 1678, which warned readers to behave with restraint if they wanted to make it into heaven. The advice manuals of the nineteenth century were less religious but still preached the value of a noble character.
