Eric Hoffer--one of America's most important thinkers and the author of The True Believer--lived for years as a Depression Era migratory worker.
Self-taught, his appetite for knowledge--history, science, mankind--formed the basis of his insight to human nature.
Nowhere is this more evident than in Hoffer's seminal work, The Ordeal of Change, essays on the duality and essentiality of change in man throughout history.
