- 1. Science and Hypothesis is a seminal work by the French mathematician and philosopher Henri Poincaré, first published in 1902, which articulates the principles of scientific inquiry and the nature of scientific theories. Poincaré explores how scientific knowledge is not merely a collection of facts but is instead constructed through hypotheses and abstraction, emphasizing that the methodology of science involves creativity and intuition as well as rigorous logical reasoning. He contends that our understanding of scientific truths is shaped by the interplay of experience, theory, and the conventions that scientists adopt for the sake of coherence and utility. Through discussions of various scientific disciplines, including physics and mathematics, Poincaré challenges the positivist view that knowledge is strictly empirical, advocating for a perspective that recognizes the role of theoretical frameworks in shaping our perceptions of reality. The book delves into concepts such as the nature of mathematical truths, the role of predictions in science, and the significance of simplicity and elegance in theoretical formulations. Poincaré's insights lay foundational ideas for the philosophy of science and continue to influence contemporary discussions about the scientific method, the development of scientific theories, and the nature of scientific revolutions.
