Essays on Mankind and Political Arithmetic

This collection brings together the early essays of a 17th‑century thinker whose restless curiosity spanned medicine, mathematics, music and social reform. Born to a modest clothier in Hampshire, he pursued a liberal education across Europe, studying Greek, Latin, optics with Hobbes, and even inventing a copying device. His first published work, a letter to the reformer Samuel Hartlib, argues for a practical, wide‑ranging curriculum that breaks the medieval hold on schooling.

The essays also reveal how his scientific training led him to apply quantitative methods to public policy, a venture that would later shape the field of political arithmetic. From restoring a condemned woman's breath to mapping Irish lands for the Commonwealth, he demonstrates a belief that precise measurement can improve human welfare. Listeners will hear a vivid portrait of a man who blended experimental observation with a grand vision of education and governance, offering early insights that still echo in modern debates on data‑driven policy.
