Many postmodernists hold one or more of the following views: (1) there is no objective reality; (2) there is no scientific or historical truth (objective truth); (3) science and technology (and even reason and logic) are not vehicles of human progress but suspect instruments of established power; (4) reason and logic are not universally valid; (5) there is no such thing as human nature (human behavior and psychology are socially determined or constructed); (6) language does not refer to a reality outside itself; (7) there is no certain knowledge; and (8) no general theory of the natural or social world can be valid or true (all are illegitimate “metanarratives”).
