Karl Marx is the most influential political philosopher of the past 150 years. Understanding him is essential to understanding post-WWII Europe, American foreign policy, contemporary China and North Korea, and much of the rhetoric in today's colleges and political circles in the United States. William Dennison's concise volume highlights the key features of Marx's worldview, including several valuable insights. Dennison's critical analysis uncovers Marx's internal contradictions, examines the inherently religious nature of his anti-religious materialism, and documents the horrifying effects of his political philosophyhorrors consistent with Marx's convictions.
