Postmodernity / Postmodernism

Recently, I have been thinking and heard quite a lot about postmodern culture, postmodernity and postmodernist theories.

In my previous posts, Emerging Church In Postmodern Context & Clergy and Modernism Versus Postmodernism, I attempted to explore the issues, and tried to make sense of some of the ideas of emerging church in the postermodern context, and realised that this was such a facinating and enormous subject, which could also be quite confusing! To many of us, the word "postmodern" may sound unfamiliar, but it's an important concept. The followings are some of the ideas that I've collected from various sources:

• Crossroad has made a great summary of the differences between modern versus postmodern cultures, as well as biblical versus postmodern thinking. They believe that if we don't understand the postmodern mindset and the changing worldviews of influential leaders and visionaries, we can't really prepare for the impact of this social revolution -- both on faith and evangelization.
• WILLIAM BLAKE AT THE ORIGINS OF POSTMODERNITY claims that "1789 marks the end of modernity and the beginning of the contemporary, post-modern, age. But the French Revolution is merely a surface event. Beneath that surface lies electromagnetism, the most revolutionary innovation of those years. Blake's manifold work follows the lines of force, the patterns of electromagnetism: both introduce into the Western culture an original set of ratios decidedly "irrational"; both depart from the established patterns of "modernity", both will have to wait many decades before further development; both Blake and electromagnetism, at the end of the eighteenth century, enjoy only precarious status as an early form of postmodernity. During the modern age, matter and energy were two different substances with no possibility of interchange. Dualism was constitutive, extreme, permanent. In our postmodern age the two are but precarious, temporary aspects of the same reality. "
• According to A reader's Guide to Contemporary Literary Theory, "the term 'postermodernism' has been the subject of much debate, especially during the 1980s and 1990s. Some see it as simply the continuation and development of modernist ideas: others have seen in postmodern art a radical break with classical modernism; while others again view past literature and culture retrospectively through post-modern eyes, identifying texts and authors as 'already' postmodern. Another arguemnt claims that the project of modernity - which designates the philosophical, social and political values of reason, equality and justice dervied from the Enlightenment - is as yet unfulfilled and should not be relinquished.

So what do you think of these observations / ideas / opinions and assertions about postmodernity / postmodernism?
