Henri Poincaré's 'The Foundations of Science' contains three
extraordinary individual works of the philosophy of science from the
early twentieth century: 'Science and Hypothesis', 'The Value of
Science' and 'Science and Method'. Poincaré was an outstanding scientist
who, writing on a whole array of scientific and mathematical topics,
advocated intuition and prediction as well as experiment and
explanation, the value of non-Euclidean geometries and the relativity of
space, thus laying the groundwork for the Einsteinian revolution in
physics. This new edition of Halsted's authorized translation from the
original French has been carefully hand-edited and re-indexed to be
clear and complete.
