Do you think postmodernistic thought and Christianity are incompatible or compatible? Wikipedia
has a good summary of Modernism. It's basically a way of looking at the world that rejects appeal to authority (Scholasticism) as a way of legitimation (that is, making sure that things are true), and embraces empirical knowledge, human reason, and an objective, universal set of values. Modernism is how we get science.
Postmodernism rejects the idea of an objective set of values, and puts more emphasis on personal preferences, needs, experiences, and values. Wikipedia
has a fragmented but fairly decent overview.
