Saving, budgeting, and investing are keys to creating wealth— but there are many different philosophies about how to approach this essential task. The “investment philosophers” offer systematic beliefs about investing that often parallel other systems of human conduct (e.g. Taoism, the hunter-warrior, etc.). The financial economists (e.g. Fisher, Keynes) offer insights about how human behavior is collectively expressed in markets. The Secrets of the Great Investors series is a collection of presentations that explain, in understandable language, the strategies, tactics, and principles that have produced great wealth, and how you can improve your financial future. History's greatest investors used powerful investing philosophies to produce superior results, and you can learn from their successes and mistakes.
