Seymour Drescher's regular, deeply-thought and carefully nuanced arguments have periodically reshaped how we think of the subject of the history of slavery itself. He has discussed the impact of economic and cultural factors on human behaviour and has shown that historical evidence does not lead to easy answers. He has changed the way in which we now look at abolitionism and has destroyed the linear explanation of economic decline. This books gathers together some of Drescher's key essays in the field.
