CO OZNACZA SŁOWO CONTRAPOSITIVE
Antyteza
W logice, contraposition jest prawem, które mówi, że oświadczenie warunkowe jest logicznie równoważne jego przeciwwskazań. Przeciwstawność tego stwierdzenia ma swoje wcześniejsze i następcze odwrócenie i odwrócenie: przeciwstawny jest więc. Na przykład, propozycja "Wszystkie nietoperze to ssaki" można przekształcić jako warunek "Jeśli coś jest nietoperza, to jest ssak". Teraz prawo mówi, że stwierdzenie jest identyczne ze sprzecznością "Jeśli coś nie jest ssakiem, to nie jest nietoperza". Kontrastowo można porównać z trzema innymi relacjami między warunkami: ▪ Odwrócenie:. "Jeśli coś nie jest nietoperzem, to nie ssak". W przeciwieństwie do wartości przeciwwagowych, odwrotna wartość prawdy wcale nie zależy od tego, czy pierwotna propozycja była prawdziwa, o czym świadczy tutaj. Odwrotna tutaj sytuacja nie jest prawdą. ▪ Konwersja:. "Jeśli coś jest ssakiem, to jest nietoperza." Konwersacja jest rzeczywiście contrapositive odwrotnym i tak zawsze ma tę samą wartość prawdy co odwrotna, co niekoniecznie jest takie samo jak oryginalnego zdania. ▪ Negacja :.
