At length I deduce that purpurea and edentuli are contradictorily opposed, similarly illiace and amabimus; for one contrary is contradictorily opposed to the subaltern of the other contrary, as omnis homo currit is contradictorily opposed to this aliquis homo non currit, because it is contained under this, nullus homo currit. The reason a priori: because purpurea is a universal negative proposition concerning the mode, while edentuli is a particular affirmative concerning the same mode, therefore they are contradictories. The consequence is clear from the definition of contradictories (the same holds for illiace and amabimus); for purpurea denies the dictum in three propositions, and affirms it in the fourth, and denies the mode in two, and affirms it in the third and fourth. But edentuli in three denies also the dictum, and affirms the mode in two, and denies it in the last two, e.g. Petrum non currere non est possibile is the first of purpurea, to which is contradicted this, Petrum non currere est possibile, which is the first of edentuli; but possibile and non possibile mutually contradict one another, which is clearer in illiace, Petrum currere non est possibile, to which amabimus, Petrum currere est possibile, contradicts; can and cannot are contradictorily opposed, nor can they be true at the same time, or false at the same time, because two contradictories would be found on the side of the thing. But they can be opposed contradictorily, as singulars, if we restrict the terms, as Petrum non currere hic et nunc (ut aiunt) non est possibile, Petrum non currere hic, et nunc est possibile, because one difference of time is signified in the particular.
