A Class Room Logic: Deductive and Inductive, with Special Application to the Science and Art of Teaching
McNair, George Hastings
Logic
(2b) “The end of a thing is its perfection; death is the end of life,
therefore death is the perfection of life.”
Indicate the fallacy in the foregoing, giving reasons.
(3a) The countries of Europe abound in beggars,
France is a country in Europe,
∴ France abounds in beggars.
“The countries of Europe” in the major premise is used in a collective
sense, while the same expression in the minor premise is used in a
distributive sense. The argument is, therefore, invalid in meaning;
_fallacy of division_.
(3b) State and explain the material fallacy in the following:
The states believe in the income tax principle; hence Vermont’s vote
will be favorable to this.
(4a) “On general principles I believe that one is better off when he
abstains from both tea and coffee; and this is the reason why I offer
you a cup of hot water.”
The individual to whom the hot water was offered might have been
in great need of a mild stimulant. Here, then, is an exception to
the general principle and the fallacy committed is clearly that of
_accident_.
(4b) “Books are a source both of instruction and amusement; a table of
logarithms is a book; therefore it is a source both of instruction and
amusement.” Jevons.
Designate with explanations the fallacy in the above argument.
(5) “Twice have I started out on Friday and both times I had tire
trouble.” Fallacy of _false cause_.
(6) “Where do you spend your vacation, in Palestine or Rome?” Fallacy
of _complex question_.
(7) “Of all the men of that department he seemed to be the most
trustworthy, and I pride myself on my ability to judge men in this
regard; but now even the police cannot find him.”
The fact that the police cannot find him has nothing to do with the
argument. The fallacy is that of _non sequitur_.
(8) “You must not whisper in _my_ classes.” Fallacy of _accent_.
(9) “I am a Progressive because I believe in progress.” Fallacy of
_figure of speech_.
(10) “I know it is true because I found it in our text book.” Fallacy
of _irrelevant conclusion_.
=11. REVIEW QUESTIONS.=

logic.

(5) What reasons may be given for such a divergence of opinion on a
proper classification of the fallacies of deduction?
(6) Give a complete outline, without explanation, of the deductive
fallacies.
(7) Distinguish between formal and material fallacies.
(8) Explain the two kinds of material fallacies.
(9) Illustrate the fallacies of immediate inference.
(10) Why should the fallacies in language be likewise termed fallacies
of equivocation?
