Treatise of Taxes and Contributions

Sir William Petty's Treatise of Taxes and Contributions (1662) was a significant early work in political economy. It explored the role of the state in economic matters and touched upon the labor theory of value. Petty, a physician, professor, inventor, and surveyor, was a founder of the Royal Society and a pioneer of political arithmetic, using quantitative reasoning for governmental analysis. His work laid groundwork for modern economics, introducing concepts like "full employment" and principles related to the present value of land rent. The book's examination of taxes and contributions aligns with broader principles of taxation, such as the ability-to-pay principle and the need for taxes to be certain, convenient, and efficient, as later articulated by Adam Smith.12
