Flashcards

Philosophy of mathematics

The study of the philosophical underpinnings, foundations, and implications of mathematics.

Logicism

A school of thought in the philosophy of mathematics that claims all mathematical concepts can be derived from principles of pure logic.

Formalism

A school of thought that sees mathematics as a formal system of symbols and rules, devoid of inherent meaning or content.

Intuitionism

A school of thought that emphasizes mental constructions and argues for a revision of classical mathematics and logic, rejecting the use of infinite sets.

Study Notes

Welcome to MATH Class!

  • This slide welcomes students to a math class.

Mathematics and Philosophy

  • The presentation is about mathematics and philosophy.
  • Prepared by: Vherline A. Doorin, LPT, Instructor I

Objectives

  • Explain the philosophy of mathematics, including mathematical logic and reasoning.
  • Recognize the significance of philosophical perspectives on mathematics and its logical foundations.
  • Use mathematical logic and reasoning to explore and discuss philosophical questions about infinity and the nature of mathematics.

The Philosophy of Mathematics

  • The philosophy of mathematics is a branch of philosophy that investigates the philosophical assumptions, foundations, and implications of mathematics.

Four Schools of Mathematical Philosophy

  • Logicism
  • Formalism
  • Intuitionism
  • Predicativism

Logicism

  • Logicism holds that mathematics is reducible to principles of pure logic.

Richard Dedekind

  • Dedekind's "logicism" embraced all mathematical concepts, including natural, rational, real, complex numbers, and geometric concepts like continuity.

Quine

  • Quine's logicism states that mathematical truth and logical demonstration go hand in hand.

Gottlob Frege

  • Frege devoted his career to showing how mathematics can be reduced to logic.

Formalism

  • Formalism views mathematics as devoid of content, focusing on the formal study of strings of mathematical symbols and their language.

David Hilbert

  • Hilbert developed the formalist perspective and published his groundbreaking work on Grundlagen der Geometrie (Foundations of Geometry).

Kurt Gödel

  • Gödel demonstrated his celebrated Incompleteness Theorems, highlighting the existence of real propositions provable by ideal means but not by concrete means.

Intuitionism

  • Intuitionism posits that mathematics is concerned with mental constructions, advocating for a revision of classical mathematics and logic.

L.E.J. Brouwer

  • Brouwer argued that mathematical theorems are synthetic a priori truths and is the proponent of intuitionism.

Predicativism

  • Predicativism emerged as a fourth program in the early 20th century.

Weyl

  • Weyl developed a philosophical stance that is, in a sense, intermediate between intuitionism and platonism.
  • Weyl regarded the set of natural numbers as unproblematically given.
