Mathematical Psychics: An Essay on the Application of Mathematics to the Moral Sciences (Classic Reprint)

Mathematics meets morality in a rigorous, readable exploration of how numbers can illuminate human choices. This work presents a two-part study of how quantitative reasoning can be applied to beliefs, feelings, and social life, from theory to real‑world use.The text argues that the science of quantity is not limited to numerical data. It shows how qualitative judgments about pleasure and pain can be analyzed with deductive methods, and it connects utilitarian ideas with mathematical reasoning. The book also traces how these tools inform contracts, markets, and social policy, while outlining the limits and responsibilities of applying math to ethics.You’ll see clear explanations of what the author calls the calculus of pleasure, the idea of greatest happiness, and the role of arbitration in coordinating competing interests. Appendices extend the discussion with practical examples and historical context, keeping the focus on how mathematics can guide moral and economic reasoning without oversimplifying complex human life.- Understand how abstract mathematical ideas relate to everyday decisions about resources, contracts, and social arrangements.- Explore the relationship between utilitarian ethics and mathematical reasoning, including debates about equality and happiness.- Learn how theories of market behavior, competition, and arbitration can be analyzed with precise, logical methods.- See how “hedonics” and the calculus of pleasure fit into broader arguments about policy and progress.Ideal for readers of philosophy, economics, and social science who want a clear, disciplined approach to applying mathematics to moral questions.
