Synthesized answer
The central thesis of Edward C. Mendler's "False Truths" is that many widely accepted "truths" are in fact invalid [Passage 1]. These questionable and false concepts are present across various fields, including philosophy, theology, cosmology, quantum physics, democracy, freedom, economics, and aspects of "human nature" and evolution [Passage 1].
