Thomas Sowell is an American Economist and author known for his objective approach to the social and economic issues of our time. He has authored several books covering and related to subjects such as economics, social theory and politics.
The reason for his inclusion into 'Great Thinkers' is due to his ability to approach subjects objectively and unemotionally. He is a calm and eloquent speaker who often promotes ideas that transcend the expectations of social norms and his particular background.
If you are open minded enough to have your ideas and opinions challenged, I highly recommend Thomas Sowell as a source of knowledge and wisdom.
