Adam Smith's Elephants

Adam Smith earned his title as the father of economics and free market capitalism with his 1776 work, commonly refered to in abbreviated form as The Wealth of Nations. Smith suggested that self interest in the form of an "invisible hand" would suffice to keep capitalism on solid footing. From this simple idea, economics would eventually branch into numerous warring schools of thought: 1) Classical School, 2) Neoclassical, 3) Keynesian, 4) Post Keynesian, 4) New Keynesian, 5) Monetarists, 6) New Classical, 7) Neo-Ricardian, 8) Marxists, 8) Austrian, and so on.
