In his search for publishing the Tractatus, Wittgenstein wrote a letter to Ludwig von Ficker while trying to explain the deeper meaning of his work, which he considered to be an “Ethical one”. Whereas other philosophers would establish theories about ethical and religious matters, Wittgenstein emphasized his decision to keep silent about the sphere transcending the world of language and of science. In this chapter, I discuss the limits of language and of science, the significance of silence, the view sub specie aeternitatis, the dimension of wonder, the difference between what can be said and what can only be shown, and Wittgenstein’s mystical approach toward the ineffable.
