W Stanley JevonsW. Stanley Jevons (1835-1882) was an influential English economist and logician, renowned for his contributions to economics, particularly the theory of marginal utility. His work laid the groundwork for modern economic thought and significantly impated the neoclassical school of economics. Jevons is best known for his book ""The Theory of Political Economy,"" published in 1871, where he introduced the concept of marginal utility, arguing that value is determined by the satisfaction derived from a good rather than its labor input. This shift was crucial in evolving economic theory from classical to modern perspectives. In addition to his economic work, Jevons was a noted logician, contributing to the field of logic through his work ""Principles of Science,"" where he explored the application of logic to scientific inquiry. His interdisciplinary approach, combining economics and logic, made a lasting impact on both fields, and his ideas continue to resonate in contemporary economic discussions. Read More Read Less
