Frege's Puzzle

Definition

Frege's Puzzle is a philosophical problem concerning the nature of meaning and reference, particularly how different expressions can refer to the same object yet convey distinct meanings. The puzzle highlights the distinction between sense (the way an expression presents its referent) and reference (the actual object that is referred to), illustrating the complexities involved in understanding language and its implications for theories of meaning.

1. Frege's Puzzle demonstrates how two different terms can refer to the same object but still have different meanings, as shown in the case of 'the morning star' and 'the evening star', both referring to Venus.
2. The distinction between sense and reference is crucial to resolving Frege's Puzzle, as it helps explain why certain identity statements can seem informative even when they refer to the same entity.
3. Frege argued that understanding a sentence involves grasping its sense, which allows speakers to derive cognitive significance from expressions.
4. Frege's work laid foundational ideas for later developments in semantics and philosophy of language, influencing figures like Bertrand Russell and Saul Kripke.
5. The puzzle raises questions about how knowledge and belief relate to language, particularly how speakers can hold beliefs about objects without necessarily knowing their identity.

Review Questions

• How does Frege's Puzzle illustrate the distinction between sense and reference in language?
  • Frege's Puzzle illustrates the distinction between sense and reference by showing how two expressions can refer to the same object while conveying different meanings. For example, 'the morning star' and 'the evening star' both refer to Venus but present it in different ways. This demonstrates that understanding language involves not just knowing what an expression refers to, but also how it presents that referent, which is captured by the notion of sense.
• Discuss the implications of Frege's Puzzle for identity statements and their informativeness.
  • Frege's Puzzle has significant implications for identity statements like 'Hesperus is Phosphorus', as it reveals how such statements can be informative despite referring to the same object. The informativeness arises from the differing senses associated with each name; understanding the identity requires grasping the distinct ways each term presents Venus. This challenges simplistic views of meaning that equate it solely with reference and emphasizes the importance of sense in comprehending language.
• Evaluate how Frege's Puzzle influences contemporary discussions on meaning and reference in philosophy and linguistics.
  • Frege's Puzzle continues to shape contemporary discussions on meaning and reference by raising critical questions about how we understand language and its role in communication. It has inspired various theories regarding the interplay of sense and reference, leading to nuanced approaches in both philosophy and linguistics. The ongoing debate about cognitive significance and how knowledge about objects relates to linguistic expressions reflects Frege's enduring impact, prompting further inquiries into how meaning is constructed and conveyed in human language.
