Wisdom of the Ancients Heraclitus (~535 – 475 bc) Harmony thru conflict  Self – regulating market Pythagorus (~582 – 507 bc) Harmony thru numbers  Equilibrium Democritus (~460 – 370 bc) Diminishing marginal utility Time preference  present value

Plato (~427 – 347 bc): preserve the status quo “…the State is the soul writ large.” First principles: Human inequalities  division of labor  social stratification {  scientific breeding} Private property  acquisitiveness  turbulence Wealth  corruption

Plato’s Ideal Republic: A stationary state The elite: Communal property/communal women –Philosophers –Soldiers Shared Austerity Philosophers Soldiers (Response to scarcity) Workers Merchants Thinking Fighting Craving No incentive to advance Society parallels the mind …the State is the soul writ large

Aristotle (384 – 322 bc): focus on individual Human inequality  distributive justice …according to individual merit In opposition to Plato: Educate, don’t regulate Private Property > Communal Property Productivity  Progress Peace (communal property  quarrels) Pleasure in ownership Philanthropy (give your own stuff as you wish) But … Acquisitiveness for acquisitiveness sake is wrong Lending at interest is unnatural –Barren money shouldn’t earn money

Transition to Smith: The Physiocrats Fixation on agriculture Manufacturing & commerce sterile Champions of laissez – faire François Quesnay (1694 – 1774) –Physician to Mme. de Pompadour What would you do as king? … Nothing! –Leader of group: disciples and associates including Mirabeau, Dupont, Turgot, … and Smith –Turgot  Franklin He snatched lightning from the sky and the scepter from tyrants. Franklin, the entrepreneur: philosophy of self interest and service –Tableau Economique  an Input-Output table Zig – zag to balance flows Agriculture  increased wealth (counter to Colbert’s favoring mfg) Taxes ultimately borne by landlords  tax land rents directly Hoarding (of money) threatens economic stability Free trade/free competition most profitable for the nation
