Cap. 55. De mixtione possibilis et contingentis in secunda figura	Chapter 55. On the mixture of possible and contingent in the second figure.
In secunda figura, si utraque sumatur in sensu compositionis, non valet mixtio. Sicut non sequitur 'omnem Deum esse hominem est possibile; nullam personam divinam esse hominem est contingens; igitur nullam personam divinam esse Deum est possibile’. Nec sequitur 'nullum Deum esse hominem est possibile; omnem personam divinam esse hominem est contingens; igitur nullam personam divinam esse Deum est possibile'. Per eosdem terminos patet quod non valet mixtio si altera praemissarum vel utraque sumatur in sensu divisionis.	In the second figure, if both are taken in the sense of composition, the mixture is not valid. Just as it does not follow that 'it is possible for every God to be a man; it is contingent for no divine person to be a man; therefore it is possible for no divine person to be God'. Nor does it follow that 'it is possible for no God to be a man; it is contingent for every divine person to be a man; therefore it is possible for no divine person to be God'. By the same terms it is clear that the mixture is not valid if one or both of the premises are taken in the sense of division.
