A Defence of Free-Thinking in Mathematics was written in response to criticisms of The Analyst in Geometry no Friend to Infidelity; or a Defence of Sir Isaac Newton and the British Mathematicians, by `Philalethes Cantabrigiensis' (Dr. James Jurin, a noted Cambridge scientist and physician), and Vindication of Sir Isaac Newton's Principles of Fluxions, by J. Walton. Berkeley responded to a subsequent pamphlet of Walton with Reasons for not replying to Mr. Walton's Full Answer.
