In this interview on the TV show The Wire, David Simon (the show's creator) says:
Much of our modern theater seems rooted in the Shakespearean discovery of the modern mind. [The show is] stealing instead from ... the Greeks ... to create doomed and fated protagonists who confront a rigged game and their own mortality. The modern mind ... finds such fatalism ancient and discomfiting ... We are a pretty self-actualized, self-worshipping crowd of postmoderns and the idea that for all of our wherewithal and discretionary income and leisure, we’re still fated by indifferent gods, feels to us antiquated and superstitious. We don’t accept our gods on such terms anymore ... we don’t even grant Yahweh himself that kind of unbridled, interventionist authority.
What exactly is meant by "the Shakespearean discovery of the modern mind"?
