This book by Nassau W. Senior, first delivered as lectures at the University of Oxford in 1851. The book explores the causes that have hindered the development of political economy, discusses political economy as a mental study, and argues for treating it as a science. It also defines wealth and presents the case for political economy as a positive, not a hypothetical science.

In this series of lectures, Richard Whately provides a clear and concise introduction to the principles of political economy. Covering topics such as supply and demand, competition, and the role of government, Whately argues for the importance of economic freedom and individual enterprise. A classic work of 19th century economic thought that remains relevant today.
