I'm exploring The Michael Eric Dyson Reader, a collection of writings and essays by the academic, author and minister. On postmodernity, Dyson writes:
Postmodernism has enjoyed a thrilling if problematic run as a leading intellectual and cultural movement among some (mostly liberal or progressive) academics. Postmodernism is composed of a complex, even ambiguous, set of ideas and practices, such as blurring the boundaries between "high" and "low" culture, rejecting grand narratives - for instance, "truth" with a capital "T," - embracing pastiche and fragmentation, and emphasizing playfulness and irony in one's intellectual exercises. A major criticism of postmodernism is that some of its advocates avoid concrete history and politics while rhapsodizing about difference, marginality, parody, and provisionality. This may account for the many American postmodernists who have overlooked the homegrown varieties of black postmodernism - and the challenges they may pose to the European imports that have colored our understanding of the concept. (p. 441)
I found this one of the more brief and enjoyable synopses of the postmodern phenomena, "stale" though it may be in this late hour.
