What happens

Wittgenstein argues that the obviousness of a proposition does not justify belief in its truth, challenging the notion that self-evidence can serve as a foundation for knowledge.

Themes in this chapter

  • Critique of Traditional Philosophy

    Undermines the traditional reliance on self-evidence as a criterion for truth.

Characters to notice

  • Mr. Wittgenstein

    Author of the proposition, critiquing the epistemic value of obviousness.

Key passages

  • If from the fact that a proposition is obvious to us it does not follow that it is true, then obviousness is no justification for our belief in its truth.

    The mere appearance of obviousness in a statement does not guarantee its truth, so obviousness cannot legitimately support our conviction that the statement is true.

    Wittgenstein rejects obviousness as a valid epistemic justification.
