  "body_markdown": "The qualification matters: Chesterton describes universal illusion, not every philosophy that makes perceived objects dependent on mind. Berkeley supplies a useful counterexample, though he is not named as the target. In the *Principles of Human Knowledge* (first published 1710; inspected here in David R. Wilkins's transcription of the 1734 edition), §§29–36 distinguish sensory objects from inventions of the imagination. Their order and independence from our wills preserve a difference between reality and fantasy; Berkeley denies material substance, not the existence of the sun, trees, or bodies. His argument is intended to resist scepticism, as §§86–88 make explicit. [Berkeley, §§29–36, 86–88](https://www.maths.tcd.ie/~dwilkins/Berkeley/HumanKnowledge/1734/HumKno.html).\n\nThis does not refute Chesterton's conditional claim about an unreal cosmos. It prevents an unwarranted expansion of that claim: denying mind-independent matter does not by itself leave thought without objects. Chesterton's own admission that the effect is indirect and doubtful leaves room for precisely this distinction.",
