If we are free from the constraints of rationality, nothing separates truth from self-delusion. The tyranny of truth has been replaced, even among academics, for self empowering stories. And these stories typically function at the expense of truth. Christians need to be respectful of what others believe and of the traditions and experiences that form those beliefs. Beliefs formed in the postmodern climate of openness and tolerance create a firewall against genuine and substantive dialogue about spiritual and moral truth.
History offers sobering testimony to the high price such anti-rational dogmatism.
Significantly, postmodern subjectivism also inhibits a deep commitment to one's own beliefs. Since faith is rooted in the practical matters of personal taste and experience, the tendency is to adopt and abandon beliefs according to the demands of the moment. Remember, truth is a human creation, not something we discover independently of ourselves. So if a truth no longer satisfies, just move on to something new. This new conventional wisdom has enormous implications for the future of evangelical Christianity in America.
