The document provides an overview of modernism and postmodernism in architecture and thought. It begins by contrasting the Pruitt-Igoe housing project from 1954, as an example of modernist architecture, with the Portland Building from 1982, designed by Michael Graves, as an example of postmodern architecture. It then discusses how postmodernism emerged from and responded to modernism, questioning universal truths and progress narratives. Key postmodern thinkers are outlined like Nietzsche, Heidegger, Foucault, Derrida, and Lyotard. Postmodernism values difference over unity and sees language as constructing reality rather than reflecting it.
