In the Tractatus, Wittgenstein declares that “There is indeed the inexpressible. This shows itself.” Theearly Wittgenstein believes that will and willing subject are inexpressible. In the 1914–1916 Notebooks, Wittgenstein uses four titles for subject: knowing subject, thinking subject, metaphysical subject, and willing subject. Willing subject is transcendental and the bearer of good and evil. Good and evil only enter through the subject. Without willing subject, there is not ethics. Wittgenstein explicitly states that ethics does not treat of the world. Ethics must be a condition of the world, like logic. Will, willing subject, and alien willare vaguely declared in Wittgenstein’s earlier teachings. This article tries to explain these concepts.
