1) Contradictory propositions possess opposite truth-values. In the diagram, they are linked by a diagonal line. If one of two contradictories is true, the other must be false, and vice versa. So the A proposition (All S are P) and the O proposition (Some S are not P) are contradictories. Clearly, if it is true that “all S are P,” then the O statement that “some S are not P” must be false. And if it is true that “some S are not P,” then the A statement that “all S are P” must be false. The same relationship holds between E (No S are P) and I (Some S are P) propositions. To use a simple example: If it is true that “all birds lay eggs,” then it must be false that “some birds do not lay eggs.” And if it is true that “some birds do not fly,” then it must be false that “all birds fly.”
Yet Ernest N. Emenyonu’s claim that the Christian missionaries “convert the people from their old ways and religious beliefs and practises […] by sheer force of an obtrusive dogma” (85) cannot hold. Instead of an ‘obtrusive dogma’, it is the attractiveness of the new faith to all those who found themselves disadvantaged in some way or other under the old one; later on, it is also the attractiveness of the mission school, due to its connection with the colonial government. And although the Christians show some aggressive traits, ‘sheer force’ is always left to the colonial power.
So what does Boston do in that case? Bring Thomas and Crowder back into the fold and hope to smooth things over? Turn around and trade one or both of them for something less than a star? Just as Cleveland probably won’t find a package like what Boston is offering, Boston can’t find another player of Irving’s stature on the current market. And if Thomas’s hip is enough of a concern for Cleveland to possibly scrap the deal, what would his trade value even be after this? The lone bright spot of an axed Irving deal would be the return of the Brooklyn pick, which Boston could either potentially flip in another deal (fans have been scheming for Anthony Davis) or use itself on a young talent in the draft.
