disimpassioned

In the light of this skepticism and criticism, postmodernism seeks to deconstruct the language of Cartesian rationality by abandoning the idea of rationality as a neutral arbiter of the rules of clear thinking; a disimpassioned means for reaching indubitable, final conclusions; and a universal guide to human thought and conduct.

The writer, Roberts-Miller asserts, is restricted to speaking in a neutral, disimpassioned voice (28-29), the audience is generalized as sharing the same beliefs and values (81-82), and the reasoning process is ontologized, that is, fact is conflated with truth (76-77).
