Postmodernism

A belief that there are no absolute social/religious/cultural truths. Relative truths exist, but they are only valid for a given culture at a given time. Other traditions, religions, eras, races, genders, cultures, and groups believe/believed in other, often conflicting, truths. All of these alternative 'truths' are valid, at least to the group that follows them.

Postmodernism has been adopted by some liberal Christians, but is regarded as a serious error by all or essentially all conservative Christians who firmly believe that absolute truths exist.
