Frege

Definition

Gottlob Frege was a German philosopher, logician, and mathematician who is known as one of the founders of modern logic and analytic philosophy. His work focused on the philosophy of language and mathematics, emphasizing the importance of logic in understanding meaning and reference. Frege's theories have had a significant impact on later philosophers, particularly concerning how names and terms relate to the objects they denote.

1. Frege introduced the concept of quantifiers and made significant advancements in predicate logic, which laid the groundwork for much of contemporary logic.
2. His famous work, 'Begriffsschrift,' published in 1879, presented a new formal language for logic that was revolutionary at the time.
3. Frege's distinction between sense and reference has become a key topic in discussions about language and meaning in philosophy.
4. He argued against psychologism, claiming that logical truths are objective and not dependent on individual thoughts or perceptions.
5. Frege's work influenced many prominent philosophers, including Bertrand Russell and Ludwig Wittgenstein, shaping the course of 20th-century philosophy.

Review Questions

• How does Frege's distinction between sense and reference enhance our understanding of language?
  • Frege's distinction between sense and reference deepens our understanding of how language operates by clarifying that the meaning of a term involves both its mode of presentation (sense) and the actual object it refers to (reference). This helps to resolve ambiguities in language, as two terms can have the same reference but different senses. For example, 'the morning star' and 'the evening star' refer to Venus but convey different information about it.
• In what ways did Frege's logicism challenge traditional views on the foundations of mathematics?
  • Frege's logicism challenged traditional views by proposing that mathematical truths are not based on empirical observations but are instead derived from logical principles. He believed that all mathematical statements could be expressed in purely logical terms, thus demonstrating that mathematics is an extension of logic. This perspective shifted how philosophers approached the relationship between math and logic, raising questions about the nature of mathematical objects and their existence.
• Evaluate the implications of Frege's contributions to modern philosophy regarding the philosophy of language and its impact on later thinkers.
  • Frege's contributions have profound implications for modern philosophy, particularly in the philosophy of language. His insights into sense and reference paved the way for later developments in semantic theory and influenced many thinkers, including Russell's theory of descriptions and Wittgenstein's later work on language games. By establishing a formal framework for analyzing meaning, Frege opened avenues for discussing how linguistic expressions relate to reality, which remains a central concern in contemporary philosophical debates.

Sense and Reference: Frege's distinction between 'sense' (the way an expression presents an object) and 'reference' (the actual object itself) is central to his theory of meaning.

Logicism: The philosophical belief, championed by Frege, that mathematics can be reduced to logic, asserting that mathematical truths are logical truths.

Predicate Logic: A formal system in logic developed by Frege that allows for the expression of statements involving predicates and quantifiers, forming the basis for modern logical theory.
