Question

C. Directions. Translate Argument #21 into symbolic notation, using the conventions in Chapter 3. Determine whether the argument is valid or invalid using the truth table method.  Use the Short-cut Method. Is it valid or is it invalid? Use the following translation dictionary: A = all of a person’s actions can be predicted in advance; D = the universe is essentially deterministic; R = people are entirely rational.

Argument #21: People being entirely rational is a sufficient condition for the following: all of a person’s actions can be predicted in advance unless the universe is essentially deterministic. It is not the case that all of a person’s actions can be predicted in advance. Thus, the universe not being essentially deterministic implies that people are not entirely rational.

Explanation / Answer

People are both rational and iirational. A person's action can be predicted well in advance if his/her character is fully studied. For example if the person is so sensitive in nature,while delivering a sad news it is optimum that the person will definetely cry and make it a hell. While when a person is deterministic in nature,even if a stubborn news reaches him,he has the gutts to face any situation.

But this will not be prevailing in each and every situation where the character of everyone cannot be noted and the situation also do not remain the same.
