Modal Logic I 174f
necessary / modal / Geach: it is even necessary necessary, that no one who is a brother is not male. Because if it were necessary only contingently, it would still be a possible option to be a brother that is not a male, even if no real opportunity! (> NNa, MMa) - if Descartes had said that necessarily God would have to create the necessity that a brother is male he would have talked big nonsense.
