I agree with you about Russell’s somewhat off-kilter understanding of Kant’s distinction between intuitions & concepts. As per the neo-Kantians, Russell construed intuition as merely an epistemic supplement to concepts, judgments, & theoretical (especially mathematical) reasoning, not as contributing an irreducibly different kind of cognitive-semantic content to judgments/propositions, arguments, & theories. And that’s especially odd, because Russell himself deployed knowledge-by-acquaintance, as the cognitive-semantic equivalent of Kantian intuition, in a directly referential way that introduces individuals, properties, relations, & logical constants themselves into propositions, arguments, & theories….
