Argument 5We should stop interfering in other countries' affairs. This follows from the fact that we have no moral right to change a country's way of governing itself. Also, interfering often gets us locked into combat; not to mention that the potential for loss of lives on both sides is high. In addition, the cost of waging wars is astronomical. Any engagement means weakening our already shaky economy. Add the fact that interfering makes us have more enemies around the world who feel threatened by us.

A single counterexample to a deductive argument is enough to show that an argument is invalid
True
T/F A stipulative definition introduces a new meaning to a term or symbol.
True
T/F A valid deductive argument is one where, assuming the missing premises are true, it is possible for the conclusion to be false
True
T/F When we are confronted with an argument we first determine the inferential claim to decide whether the argument is deductive or inductive. Only then do we ask one (and only one) of these questions: If the argument is deductive, we ask: "Is the argument valid?" If the argument is inductive, we ask: "Is the argument strong?" We never ask of an inductive argument whether it is valid, nor of a deductive argument whether it is strong. Doing so would make little sense. Characterizing an argument as deductive does not mean saying that it is valid. Characterizing an argument as deductive only means identifying the inferential claim as such. There are invalid deductive arguments after all. [This is not a trick question. (There aren't any trick questions on homework assignments or exams.)It is included because these points are very important. So, make sure to remember them!]
