Part 1:
Below are basic arguments in English. Choose one argument andtranslate the argument into the symbolism of predicate logic. Useone of the proof techniques from Chapter 8 to demonstrate thevalidity of the argument.
1. Every fetus has an immortal soul. A thing has an immortalsoul only if it has a right to life. Hence, every fetus has a rightto life. (Fx = x is a fetus, Sx = x has an immortal soul, Rx = xhas a right to life).
2. Some wars are just. No war of aggression is just. Therefore,there are wars that are not wars of aggression. (Wx = x is a war,Jx = x is just, Ax = x is a war of aggression).
3. At least one instance of intentional killing is not wrong.But every murder is wrong. Hence, some instances of intentionalkilling are not murder. (Kx = x is an instance of intentionalkilling, Wx = x is wrong, Mx = x is murder)
4. Only things that have human bodies are human. No soul has ahuman body. Only souls survive the death of the body. Therefore, nohumans survive the death of the body. (Bx = x has a human body, Hx= x is human, Sx = x is a soul, Dx = x survives the death of thebody)
Part 2:
Now, construct an alternate proof. In other words, if the proofwas done using RAA, now use CP; if you used CP, now use RAA.Consider the following questions, as well, in your journalresponse: • Will a direct proof work for any of these? • Can theproof be performed more efficiently by using different equivalencerules?
