Translate each argument into symbolic form. Then determine whether the argument is valid or invalid. You may use a truth table or, if applicable, compare the argument's symbolic form to a standard valid or invalid form. (You can ignore differences in past, present, and future tense.) If we are to have peace, we must not encourage the competitive spirit. If we are to make progress, we must encourage the competitive spirit. \(\therefore\) We do not have peace and we do not make progress.
Translate each argument into symbolic form. Then determine whether the argument is valid or invalid. If it was any of your business, I would have invited you. It is not, and so I did not.
Based on the following argument by conservative radio talk show host Rush Limbaugh and directed at former vice president Al Gore. You would think that if \(\mathrm{Al}\) Gore and company believe so passionately in their environmental crusading that [sic] they would first put these ideas to work in their own lives, right? ... Al Gore thinks the automobile is one of the greatest threats to the planet, but he sure as heck still travels in one of them - a gas guzzler too. (See, I Told You So, p. 168) Limbaugh's passage can be expressed in the form of an argument: If Gore really believed that the automobile were a threat to the planet, he would not travel in a gas guzzler. Gore does travel in a gas guzzler. Therefore, Gore does not really believe that the automobile is a threat to the planet. Use Limbaugh's argument to determine whether each statement makes sense or does not make sense, and explain your reasoning. I know for a fact that \(\mathrm{Al}\) Gore does not travel in a gas guzzler, so Limbaugh's argument is invalid.
Translate each argument into symbolic form. Then determine whether the argument is valid or invalid. You may use a truth table or, if applicable, compare the argument's symbolic form to a standard valid or invalid form. (You can ignore differences in past, present, and future tense.) If it rains or snows, then I read. I am not reading. \(\therefore\) It is neither raining nor snowing.
Translate each argument into symbolic form. Then determine whether the argument is valid or invalid. You may use a truth table or, if applicable, compare the argument's symbolic form to a standard valid or invalid form. (You can ignore differences in past, present, and future tense.) If all people obey the law, then no jails are needed. Some people do not obey the law. \(\therefore\) Some jails are needed.
