1. Is the following argument valid? In order to determine this, (1) make a translation key, then (2) construct a truth table, indicating how it shows that it is either valid or invalid. (NOTE: You don't need to calculate every individual truth value assignment for every sub- formula (though you may), you only need to, at a minimum, show what truth values the whole wffs (each premise and the conclusion) have on each truth value assignment.) 'If moral truths are relative, then they are either relative to individuals or relative to cultures. If moral truths are relative to individuals, then a psychopath's morality is as good as Mother Teresa's. A psychopath's morality is not as good as Mother Teresa's. So, If morals are relative, then they are relative to cultures.'
