b. Write the argument in standard form, including the missing premise or conclusion needed to make the completed argument validif possibleusing parameters if necessary.
c. Name the order of the enthymeme.
d. If the argument is not valid even with the understood premise included, name the fallacy that it commits.
Example Problem
Transgenic animals are manmade and as such are patentable.
Alan E. Smith, cited in Genetic Engineering
(San Diego, CA: Greenhaven Press, 1990)
Example Solution
a. The premise understood but not stated here is that whatever is manmade is patentable.
b. Standard-form translation:
All manmade things are patentable things.
All transgenic animals are manmade things.
Therefore, all transgenic animals are patentable things.
c. The enthymeme is first-order, because the premise taken as understood is the major premise of the completed argument.
d. This is a valid syllogism of the form AAA1, Barbara.

Example Solution
This is a pure hypothetical syllogism. Valid.
PROBLEMS

G. E. Moore, Some Main Problems of Philosophy (New York: Allen & Unwin, 1953)
15. It is clear that we mean something, and something different in each case, by such words [as substance, cause, change, etc.]. If we did not we could not use them consistently, and it is obvious that on the whole we do consistently apply and withhold such names.

PROBLEMS
15. The decision of the Supreme Court in U.S. v. Nixon (1974), handed down the first day of the Judiciary Committees final debate, was critical. If the President defied the order, he would be impeached. If he obeyed the order, it was increasingly apparent, he would be impeached on the evidence.
Victoria Schuck, Watergate, The Key Reporter, Winter 19751976
16. If we are to have peace, we must not encourage the competitive spirit, whereas if we are to make progress, we must encourage the competitive spirit. We must either encourage or not encourage the competitive spirit. Therefore we shall either have no peace or make no progress.
17. The argument under the present head may be put into a very concise form, which appears altogether conclusive.

On the first supposition, it will be restrained by that dependence from forming schemes obnoxious to their constituents. On the other supposition, it will not possess the confidence of the people, and its schemes of usurpation will be easily defeated by the State governments, who will be supported by the people.
James Madison, The Federalist Papers, no. 46, 1788
18.
a man cannot enquire either about that which he knows, or about that which he does not know; for if he knows, he has no need to enquire; and if not, he cannot; for he does not know the very subject about which he is to enquire.
Plato, Meno
19. We tell clients to try to go through the entire first interview without even mentioning money. If you ask for a salary that is too high, the employer concludes that he cant afford you. If you ask for one that is too low, youre essentially saying, Im not competent enough to handle the job that youre offering.
James Challenger, What to Doand Not to DoWhen Job Hunting, U.S. News & World Report, 6 August 1984
20. Pascals wager is justifiably famous in the history of religion and also of betting. Pascal was arguing that agnosticspeople unsure of Gods existenceare best off betting that He does exist. If He does but you end up living as an unbeliever, then you could be condemned to spend eternity in the flames of Hell. If, on the other hand, He doesnt exist but you live as a believer, you suffer no corresponding penalty for being in error. Obviously, then, bettors on God start out with a big edge.
Daniel Seligman, Keeping Up, Fortune, 7 January 1985
