Intellectual Lineage
Munger draws explicitly from: Benjamin Franklin (self-improvement, practical wisdom), Charles Darwin (disconfirming evidence method), Jacobi (inversion), Epictetus and Marcus Aurelius (stoic resilience), Cicero (multidisciplinary knowledge), Robert Cialdini (psychology of influence), Adam Smith and David Ricardo (economics), B.F. Skinner (incentive power), Max Planck (limits of knowledge).
Approach to Investing
Munger shifted Buffett from Graham-style cigar-butt investing toward buying wonderful businesses at fair prices. Key principles: concentrated patience, moats, circle-of-competence, and the pari-mutuel analogy (the market adjusts odds like a betting system, so edge requires thinking differently from the crowd).
