Postmodernist label includes many diverse intellectual trends.
From the perspective of skeptical postmodernism, all interpretations of phenomena are equally valid, and the world is so complicated that concepts such as prediction and causality are irrelevant. Affirmative postmodernism retains the possibility of making discriminations among competing interpretations. Postmodernism involved a rejection of overarching propositions, an acceptance of pluralism and fragmentation, an emphasis on difference and heterogeneity, and an ironic admission of the ephemerality of things. Postmodernism, compared to modernism, aims to communicate both to the concerned minority of technical experts in the field and to the wider population of those affected by the practice of science. Our postmodernist perspective seeks to include and use techniques, insights, methods, and approaches from a variety of traditions, reaching backwards, forwards, and sideways with little regard for academic boundaries or the myth of progress that condemns some texts as old fashioned while proclaiming others state of the art.
