Wittgenstein’s metaphor of the beetle in the box in the Philosophical Investigations has been the object of a robust critique by Petr Koťátko. In the book Interpretace a subjektivita (Interpretation and Subjectivity) he resolutely opposes the view that mental experiences do not figure in our vocabularies of the mental, which he associates with the metaphor in question. The aim of this article is to show that the critique in question is founded on a misunderstanding of the real sense of the metaphor. Its motivation is quite different. In addition, the aim is to show that, in reality, there is agreement between Koťátko’s critical thoughts and the motivation of Wittgenstein’s metaphor of the beetle in the box.
