Description

The Metaphysics of Ordinary Language Philosophy. The Application of the Principle of Expressibility from Plato to Wittgenstein.
(Text in German)
Since ordinary language philosophy is widely regarded as a philosophical trend of the 20th century having a critical or even anti-metaphysical attitude, its significance for history and also for metaphysics has often been underestimated. In fact, three typical arguments used in ordinary language philosophy - substitution tests, sequence formation tests and language game tests - are based on a metaphysical principle: the principle of expressibility.
In this work, the author shows that these arguments are not only used in the 20th century but that they have also been found in classical philosophical texts since Plato.
