Discuss the objections that have been urged against the Syllogistic Theory. 2. State Whately's definition of Logic, and show how he arrives at it. 3. State Mr. Mill's view of the Syllogism. 4. Explain the principal theories of Predication. 5. State and illustrate Whately's rule for ascertaining in practice what is really the predicate of a proposition. How does he apply it to the proposition, A is not B (where the emphasis is on not)? 6. What is the meaning, and what the application, of the maxim, "Nota notæ est nota rei ipsius"? 7. Explain the meaning of "second intention" according to Whately, and according to the older logicians, respectively. 8. State Whately's solution of the fallacy : therefore, Food is necessary to life; Corn is food; Corn is necessary to life; and examine its correctness. 9. Examine briefly the nature of the hypothetical Syllogism. 10. Examine Zeno's argument against the possibility of Motion. 11. If a hypothetical proposition is not certain, but only probable, show that the reasoning from the remotion of the consequent to that of the antecedent is invalid. MR. JELLETT. 1. It is proposed to prove by induction that all bodies which possess a certain property A, possess also a certain other property B; what rule should be followed in choosing the instances of which the induction is composed? a. Two bodies agree only in the qualities A and B, therefore every body which possesses one of these qualities also possesses the other; state whether this argument be valid or invalid, and give the reason of your answer. 2. He who believes the Scripture to have proceeded from Him who is the Author of Nature may well expect to find the same sort of difficulties in it as are found in the constitution of Nature. Arrange this argument in logical form: a. State the exact logical nature of the argument from analogy, when used to refute another argument. 3. "Every person practically lays claim to infallibility, inasmuch as he always believes himself to be right in his opinions." Arrange this argument in logical form, and determine whether it be valid or invalid; giving the reason of your answer. determine whether this argument be valid or invalid. 5. "With some of them God was not well pleased, for they were overthrown in the wilderness." State this argument as a syllogism. 6. When an extenuating circumstance is alleged in the case of a crime, it is commonly replied, "That is no excuse." Point out the fallacy involved in this answer. MR. TARLETON. 1. Prove that the Dictum de omni et de nullo includes all the general and special rules of Syllogism; hence show that with the exception of useless modes there are none legitimate except those received. |
