Presented by Willard Hurst as part of his course "Introduction to Modern American Legal History" at the University of Wisconsin Law School in 1978. Hurst begins the lecture with an examination of the Treatise of Henry George and the thoughts of William Graham Sumner. He then goes on to discuss some of the costs and benefits of legal initiative, and the facilitative and regulatory aspects of law. He concludes with an analysis of the physical limits on space and human energy, and the public health institutions and land policies that combat these issues.
