What Mathematics is, Really



“Should the philosophy of mathematics be precise? ...Mathematics is precise; philosophy cannot be. Expecting philosophy of mathematics to be a branch of mathematics, with definitions and proofs, is like thinking philosophy of art can be a branch of art, with landscapes and still lives.... It happens that the creators of foundationist philosophy of mathematics were mathematicians (Hilbert, Brouwer) or mathematically trained (Husserl, Frege, Russell). This training may explain their bias. They sought to turn philosophical problems into mathematical problems, to make them precise. This bias was fruitful mathematically. Some of today’s mathematical logic descended from the search for mathematical solutions to philosophical problems. But, even though mathematically fruitful, it was philosophically misguided.”

For many years, the mathematicians, scientists and philosophers, had tackled this issue and which are still being asked today. The main purpose of the book is to confront philosophical problems: In what sense do mathematical objects exist? How can we have knowledge of them? Why do mathematicians think mathematical entities exist forever, independent of human action and knowledge? The book proposes an unconventional answer: mathematics has existence or reality only as part of human culture. Despite its seeming timelessness, it is a social, cultural, historic phenomenon.

What Is Mathematics, Really? opens with an astonishing dialog between Hersh and a 12-year old girl about the kinds of questions that can begin to help us understand what the philosophy of mathematics is all about, and what is at stake in the process.

               This is a well written, well argued and fascinating book. It contains important arguments that push back the boundaries of debates in the philosophy of Mathematics. It proposes an important new position in the philosophy of Mathematics: Hersh's humanism. It serves both a challenge to philosophers of Mathematics and even normal citizens. It deserves to beread by all interested in mathematics and its philosophy, from philosophers and mathematicians to students and interested members of the public.

  1. "Mathematics is precise; philosophy cannot be." Yes, indeed.

  2. You say that the book "deserves to be read by all interested in mathematics and its philosophy", but how about those that have no interest at all?

  3. The conversation with Laura did help a bit in understanding about the philosophy of math. i like how passionate Hersh was in writing the book.. you can really see how he loves math. Indeed, the book should be read by those who are interested in math and its philosophy.. but i think those who have no interest will think otherwise XD
