Science and Method

Question

The first chapter of *Science and Hypothesis* in this volume is titled "On the Nature of Mathematical Reasoning," focusing on "Syllogistic Deduction," "Verification and Proof," and "Elements of Arithmetic." Given the broad title "The Foundations of Science," why might Poincaré choose to begin with these specific mathematical concepts? What foundational role do they play in understanding science more generally?

Synthesized answer

Poincaré begins with mathematical reasoning, specifically syllogistic deduction and verification, because he believes these concepts are foundational to understanding science more generally [1, 4]. He explores what makes mathematical reasoning so fruitful and rigorous, suggesting it is not purely deductive and partakes in inductive reasoning [2, 3, 4]. This rigor is essential because if science were certain but lacked significance, it would be powerless and incapable of teaching us about reality [2].

The passages indicate that mathematical reasoning, when analyzed deeply, is not simply deductive as commonly supposed [2]. It possesses a "creative virtue" that differentiates it from the syllogism [3]. The science of mathematics, if reduced to a series of verifications, would not be a science, as science exists apart from the general [5]. Therefore, understanding the nature of mathematical reasoning is a necessary step before examining other sciences [2]. However, the passages do not explicitly detail how these specific mathematical concepts lay the groundwork for understanding science more broadly beyond their inherent rigor and fruitfulness.

From the book

would lack that guidance which, as M. Poincaré has shown, the larger ideas of science give to empirical investigation. V I have dwelt, no doubt, at too great length upon one aspect only of our author's varied and well-balanced discussion of the problems and concepts of scientific theory. Of the hypotheses in the narrower sense and of the value of direct empirical control, he has also spoken with the authority and the originality which belong to his position. And in dealing with the foundations of mathematics he has raised one or two questions of great philosophical import into which…

ot simply created by his own caprice.[1] Under these conditions science would be certain, but deprived of significance. [1] See Le Roy, 'Science et Philosophie,' _Revue de Métaphysique et de Morale_, 1901. If this were so, science would be powerless. Now every day we see it work under our very eyes. That could not be if it taught us nothing of reality. Still, the things themselves are not what it can reach, as the naïve dogmatists think, but only the relations between things. Outside of these relations there is no knowable reality. Such is the conclusion to which we shall come,…

we not have good reason to ask whether the whole syllogistic apparatus did not serve solely to disguise our borrowing? The contradiction will strike us the more if we open any book on mathematics; on every page the author will announce his intention of generalizing some proposition already known. Does the mathematical method proceed from the particular to the general, and, if so, how then can it be called deductive? If finally the science of number were purely analytic, or could be analytically derived from a small number of synthetic judgments, it seems that a mind sufficiently…

ave thought proper to show him at work. For that I have taken instances from the history of optics and of electricity. We shall see whence have sprung the ideas of Fresnel, of Maxwell, and what unconscious hypotheses were made by Ampère and the other founders of electrodynamics. PART I NUMBER AND MAGNITUDE CHAPTER I ON THE NATURE OF MATHEMATICAL REASONING I The very possibility of the science of mathematics seems an insoluble contradiction. If this science is deductive only in appearance, whence does it derive that perfect rigor no one dreams of doubting? If, on…

on only because it is particular. Every particular enunciation in mathematics can always be verified in this same way. But if mathematics could be reduced to a series of such verifications, it would not be a science. So a chess-player, for example, does not create a science in winning a game. There is no science apart from the general. It may even be said the very object of the exact sciences is to spare us these direct verifications. III Let us, therefore, see the geometer at work and seek to catch his process. The task is not without difficulty; it does not suffice to open a…
