Both poststructuralist strands derive their core from Nietzsche

Evidence

Born in Röcken in Prussia in 1844, Nietzsche set out on his brilliant career in philology, but turned to writing idiosyncratic philosophical treatises and collections of aphorisms. He directed these against the pious dogmas of Christianity and of traditional philosophy alike: for him, both were self-serving veils drawn over the harsher realities of life. What was needed, he felt, was not high moral or theological ideals, but a deeply critical form of cultural history or ‘genealogy’ that would uncover the reasons why we humans are as we are, and how we came to be that way. For him, all philosophy could even be redefined as a form of psychology, or history. He believed that every great philosopher actually wrote ‘a kind of involuntary and unconscious memoir’ rather than conducting an impersonal search for knowledge. Studying our own moral genealogy cannot help us to escape or transcend ourselves. But it can enable us to see our illusions more clearly and lead a more vital, assertive existence. — Sarah Bakewell, At the Existentialist Café, 63 (#expands, via linked claim)

Nevertheless, it gradually became clear that postmodernism represented the convergence of three distinct cultural trends. The first involved certain changes in the arts over the previous couple of decades - in particular, the reaction against the International Style in architecture associated with such names as Robert Venturi and James Sterling which first brought the term ‘Postmodern’ into popular usage. … Secondly, however, a certain current in philosophy was thought to be giving conceptual expression to the themes explored by contemporary artists. This was a group of French theorists who came in the 1970s to be known in the English-speaking world by the shared label of ‘poststructuralism’ - in particular, Gilles Deleuze, Jacques Derrida and Michel Foucault. Despite their many disagreements, all three stressed the fragmentary, heterogeneous and plural character of reality, denied human thought the ability to arrive at any objective account of that reality and reduced the bearer of this thought, the subject, to an incoherent welter of suband trans­ individual drives and desires. — Alex Callinicos, Against Postmodernism, 27 (#expands, via linked claim)
