What happens

Wittgenstein discusses the perception of complexes, explaining that perceiving a complex involves recognizing how its constituents are combined. He uses the example of a cube figure that can be seen in two ways, illustrating that we perceive two different facts depending on our focus.

Themes in this chapter

  • Logical Atomism

    The analysis of complexes into constituents and their combination reflects logical atomist ideas.

  • Picture Theory of Language

    Perceiving a complex as a combination of constituents parallels the idea of propositions as pictures of facts.

Characters to notice

  • Mr. Wittgenstein

    Author of the proposition, exploring the nature of perception and complexes.

Key passages

  • To perceive a complex means to perceive that its constituents are combined in such and such a way.

    Perceiving a complex is recognizing how its parts are arranged together.

    Clarifies the relationship between perception and the structure of complexes.

  • This perhaps explains that the figure can be seen in two ways as a cube; and all similar phenomena.

    This might account for ambiguous figures like the Necker cube and similar perceptual illusions.

    Connects the philosophical point to a concrete perceptual example.
