The performative self-refutation Berkeley identifies applies equally to Berkeley's own claims about minds perceiving — the argument proves too much and collapses into solipsism without independent grounding.

Berkeley(as the author being discussed): George Berkeley was an Irish philosopher from the 1600s-1700s who argued that physical objects don't exist independently of being perceived—they only exist because someone is thinking about or observing them.
Independent grounding(what Poincaré argues geometry doesn't need): A separate, outside reason or foundation that would justify or require something to be true beyond just usefulness or convention.
Performative self-refutation(as used in logic and argumentation): When the act of saying something proves that what you said is false—like saying 'I can't speak English' in perfect English.
proves too much(Applied to Pascal's Wager to show it would equally justify belief in incompatible theistic hypotheses): A dialectical objection where an argument is shown to be flawed because the same form of reasoning, applied consistently, would justify conclusions that are clearly false or mutually contradictory.
