Context and Significance of Commonsense Philosophy Commonsense philosophy underscores the value of everyday knowledge and beliefs, countering skepticism and idealism. This philosophical approach champions the reliability of ordinary experiences, asserting that our commonplace beliefs offer a sturdy foundation for knowledge.
Overview of G.E. Moore, Bertrand Russell, and Ludwig Wittgenstein
Importance of Defending Commonsense in Their Works These philosophers make the defense of commonsense central in their writings. They argue that everyday beliefs are generally trustworthy and provide a reliable basis for knowledge, countering skepticism, idealism, and other views undermining ordinary experience.
Moore’s Critique of Idealism
Moore criticizes idealism, asserting that it undermines commonsense beliefs about an external, mind-independent world. His commitment to realism drives this critique, emphasizing the world's existence beyond our perceptions and thoughts.
The Concept of "Common Sense" in Moore’s Philosophy
In Moore's philosophy, "common sense" refers to everyday beliefs and assumptions that help us comprehend and navigate the world. These beliefs include the existence of an external world, other minds, and the reliability of our senses. Moore contends that common sense is more certain and justifiable than philosophical theories contradicting it.
Moore’s Works: "Proof of an External World" and "A Defence of Commonsense"
Russell’s Logical Atomism and Its Relation to Commonsense
Russell's logical atomism posits that the world comprises simple, independent facts represented by elementary propositions. This aligns closely with his defense of commonsense, offering a framework to understand the world's structure and the nature of our knowledge. Russell asserts that commonsense beliefs derive from the objective structure of reality, rendering them reliable.
Russell’s Critique of Idealism and Defense of Realism
Russell, like Moore, criticizes idealism. His commitment to realism asserts that the world exists independently of our thoughts. Russell contends that realism provides a more plausible account of everyday experiences, strengthening the foundation for commonsense beliefs and philosophical inquiry.
The Role of Commonsense in Russell’s "The Problems of Philosophy"
Russell's book "The Problems of Philosophy" explores various philosophical issues, emphasizing commonsense as a starting point for philosophical inquiry. He argues that commonsense beliefs are a solid foundation for knowledge, and any view opposing them is likely flawed or misguided.
Wittgenstein’s "Tractatus Logico-Philosophicus" and Its Connection to Commonsense
Ludwig Wittgenstein's early work, the "Tractatus Logico-Philosophicus," delves into the interplay between language, thought, and reality. While not explicitly focused on commonsense, his ideas have implications for its defense.
The Picture Theory of Meaning and Its Impact on Commonsense
Wittgenstein introduces the picture theory of meaning, stating that propositions depict the world by illustrating states of affairs. This theory suggests that our everyday beliefs and statements are rooted in the objective structure of reality, bolstering the trustworthiness of commonsense beliefs.
Wittgenstein’s Critique of Metaphysics and Language’s Limits
The "Tractatus" includes a critique of metaphysics, which Wittgenstein deems nonsensical due to their inability to be represented in language. Wittgenstein's critique implies that some philosophical challenges to commonsense stem from linguistic misunderstandings.
