Well, Peter, no sooner I corrected one error of logic on your part than,
lo and behold, another one is coming up. But never fear, we have
resources for all occasions. So here's some more help to fill in the gaps
in your education.

                             APPEAL TO AUTHORITY
                        (ARGUMENTUM AD VERECUNDIAM)

                Definition:
                
             While sometimes it may be appropriate to cite an authority
                 to
                 support a point, often it is not. In particular, an
                 appeal to
                 authority is inappropriate if:
                 (i) the person is not qualified to have an expert
                 opinion on the subject,
                 (ii) experts in the field disagree on this issue.

[Please note the above, Peter...]

                 (iii) the authority was making a joke, drunk, or
                 otherwise not being serious
                 
                 A variation of the fallacious appeal to authority is
                 hearsay. An
                 argument from hearsay is an argument which depends on
                 second or third hand sources.
                 
        Examples:
                
             (i) Noted psychologist Dr. Frasier Crane recommends that
                 you buy the EZ-Rest Hot Tub.
                 (ii) Economist John Kenneth Galbraith argues that a
                 tight
                 money policy s the best cure for a recession. (Although
                 Galbraith is an expert, not all economists agree on
                 this
                 point.)
                 (iii) We are headed for nuclear war. Last week Ronald
                 Reagan remarked that we begin bombing Russia in five
                 minutes. (Of course, he said it as a joke during a
                 microphone test.)
                 (iv) My friend heard on the news the other day that
                 Canada
                 will declare war on Serbia. (This is a case of hearsay;
                 in
                 fact, the reporter said that Canada would not declare
                 war.)
                 (v) The Ottawa Citizen reported that sales were up 5.9
                 percent this year. (This is hearsay; we are not n a
                 position to
                 check the Citizen's sources.)
                 
        Proof:
                
             Show that either (i) the person cited is not an authority
                 in the
                 field, or that (ii) there is general disagreement among
                 the
                 experts in the field on this point.
