Daniel Quinn was largely a fiction writer who explored the culturally-biased world-view ("mythology", in his terms) driving modern civilization and the destruction of the natural world. He sought to recognize and criticize some of civilization's most unchallenged "myths" or "memes", which he considered to include the following: that the Earth was made especially for humans, so humans are destined to conquer and rule it; that humans are innately and inevitably flawed; that humans are separate from and superior to nature (which Quinn called "the most dangerous idea in existence"); and that all humans must be made to live according to some "one right way".
