Abstract
Ludwig Wittgenstein as a student of Bertrand Russell and Friedrich Schiller as a student of Immanuel Kants use hardly any meta-theoretical concepts for their theoretical writings. An rare exception, in which both authors meet philosophically, is the concept of the game.
Both take the game serious and show with it a playful way out of the petrified-serious philosophical theory into the fluid-livingness of human practice. In Wittgenstein and Schiller the game stands for a meta-theoretical concept which contains its own negation and sublation regarding to its former mere theoretical meaning.
In the following, the story of the serious game is told, as an sublation of the serious philosophical thinking of Russell and Kant, together with the manifestation of the game in the History of Philosophy through Wittgenstein and Schiller.
