The Decline of the Left Hemisphere Culture

I think the idea is that we've rejected this age of reason. And so left hemisphere dominated culture will see a decline in literature, in poetry and imagery. So I accept that in intellectual history, there has been a shift away from that narrowly analytic way of thinking. But I say that's only in pockets within academia. What is much common is this cod poststructures and postmodernism that anything goes because everything is equally true. Well, if everything's equally true, why don't we all just cut our throats now? You can never be certain about it. It's always up for grabs or aren't any rules for defining what exactly is true.
