So now the suspicion is centered on "all". >Russell's paradox, >"All", >Universal quantification. Poincaré saw this suspicion confirmed and claimed: Conditions such as "~ (x ε x)" are unsuitable to determine a set, for they require a circulus vitiosus. >Sets, >Set theory, >Classes, cf. >Outermost class, >Circularity, cf. >Self-reference. He did not get to this diagnosis with the help of the Russellian antinomy, but with the antinomy constructed by Jules Richard. >Paradoxes/Poincaré.},
