Transaction costs provide the key to understanding Adam Smith's complete philosophical system and how his two great works form an integrated whole.
• Smith's two essential claims: humans desire to learn proper behavior and have an innate propensity to truck, barter, and exchange
• Sympathy in Smith's view means synchronizing feelings with others—not perfect emotional matching but sufficient "concords" for social harmony
• Three core principles guide proper behavior: justice (respecting others' person, property, and promises), beneficence (proper use of what's ours), and prudence (sacrificing present comfort for future well-being)
• Self-command turns virtuous intentions into actual proper behavior
• Four sources of moral judgment: motive, reaction, convention, and consequence
• As societies scale up, we move from moral community (acting from love) to moral order (following rules from their utility)
• Smith's "Chinese earthquake" example anticipates the modern trolley problem by revealing how moral agency affects our decisions
• The "man of system" tries to impose ideal plans without regard for human nature or gradual change
• Smith's egalitarian views positioned economics against slavery and hierarchical social structures
