The result is a collection of thought-provoking discussions that span the fields of sociology, politics, economics, criminology, geography and many more.From the people who brought us the Philosophy Bites series, Big Ideas in Social Science is a fascinating and accessible introduction to the key ideas and findings of the social sciences.
