A Treatise of Taxes and Contributions

This is where economics begins. William Petty, the eccentric father of political economy, wrote this treatise in 1662 while shuttling between the fractious politics of Restoration England and his contentious land claims in Ireland. What makes this book remarkable is not its subject matter, taxes are never glamorous, but its radical method. Petty refuses to reason in abstractions. Instead, he counts. He measures land, estimates populations, calculates the productive capacity of a nation. He essentially invents the first crude national income accounting, a full century before such ideas would be formalized. The book argues that taxes are not merely extraction but a conversation between state and subject: what you take should bear some rational proportion to what the nation produces. Petty writes with the manic energy of a man who has survived political upheaval and come out the other side convinced that numbers, not bloodlines, should govern how societies understand themselves. For anyone curious about where modern economic thinking comes from, or for anyone who suspects that the arguments about taxation raging today have very old roots, this treatise remains startlingly fresh.
