The Foundations of Science gathers Henri Poincaré's three major philosophical works—Science and Hypothesis, The Value of Science, and Science and Method—into a sustained inquiry into the logic, limits, and creative power of scientific knowledge. Written with unusual elegance for technical philosophy, the volume ranges across mathematics, physics, geometry, astronomy, and epistemology, arguing that scientific principles are neither mere facts nor arbitrary conventions but disciplined constructions shaped by experience, simplicity, and utility. It stands at the threshold of modern physics, illuminating the intellectual climate that made relativity and twentieth-century philosophy of science possible. Poincaré, one of the greatest mathematicians of the late nineteenth and early twentieth centuries, was also a physicist, engineer, and profound reflective thinker. His work on celestial mechanics, topology, differential equations, and electrodynamics gave him intimate knowledge of scientific practice from within. This breadth enabled him to write not as an external commentator but as a creator of science, attentive to intuition, invention, and the role of hypothesis in discovery. This book is essential for readers interested in how science justifies its truths, revises its concepts, and preserves objectivity without naïve realism. Philosophers, historians of science, mathematicians, and scientifically minded general readers will find in Poincaré a lucid guide to the intellectual architecture of modern knowledge.
