Rorty founded pragmatism -> which is basically that words only get their meanign based on how they're used
French postmodernists on the other hand did different things all attacking Grand narratives (as Lyotard would describe it). Derrida problematized the structuralist method of deriving meaning. Foucault attacked meta-narratives like Sexuality and Physical sciences, showing they're not independent of culture. And Baudrillard too showed the hyperreal becomes more real than the real.
How did these 2 methodologies lead to the same conclusions ?
