Monk notes that after Wittgenstein arrived back in
As Monk mentions, a concept of “showing” is seen in the Tractatus. For example, Wittgenstein says things like, “What can be shown, cannot be said,” which expresses the weakness in language. Wittgenstein takes this notion further in his later philosophy. Monk notes as an example, “Appreciation takes a bewildering variety of forms, which differ from culture to culture, and quite often will not consist in saying anything. Appreciation will be shown, by actions as often as by words.” Wittgenstein also laments his inability to write poetry, since “poetry is able to show what cannot be said.”
Wittgenstein also uses images in his writing in order to better show his meaning. For example, in “Philosophy of Psychology – A Fragment” (originally known as Part II of Philosophical Investigations), Wittgenstein borrows Jastrow’s picture of “the duck-rabbit”
to show that at times people have different interpretations or perceptions of illustrations.
