This e-book focuses on the ideas of the nineteenth century American social and economic philosopher, Henry George, (1839-1897). George published Progress and Poverty in 1879 and it very quickly became the most widely read book on economics in the late nineteenth and early twentieth centuries. This fact will astonish many people today. The historical influence of Progress and Poverty has become obscured, indeed almost obliterated, since the Second World War. George was an autodidact, populist reformer, skilled orator and elegant philosopher of economics, who had a global following which reached its pinnacle in the first decade of the twentieth century. This was a popularity that had substantive political and legislative effects in such diverse places as the United States, England, Australia and Africa. George's ideas, his corpus of publications and its scholarly commentary, long since relegated to the outermost margins of the academic discipline of economics, are once again finding a renascence. And for good reason.
