“In what follows, a reading of Wittgenstein’s remarks will be offered according to which Wittgenstein subscribes to a form of dialetheism (that is, the view that there are sentences that are both true and false). In contrast to modern dialetheist approaches to the Liar, however, some of Wittgenstein’s remarks suggest combining a dialetheist position with what is called ‘logical nihilism’ (that is, the view that there are no universally valid inference rules).”
You can tell #Kuhn is thinking of #Wittgenstein, PI here: "to imagine a language means to imagine a form of life." This is from "Scientific Knowledge as Historical Product," 1977, first essay in The Essential Tension and also in The Last Writings of Thomas S. Kuhn.
