GENERAL EXERCISES IN TESTING THE
VALIDITY OF CATEGORICAL ARGUMENTS.
_Let the student give attention to the fallacies in meaning as well as
to the fallacies in form._
1. None but those who are contented with their lot in life can
justly be considered happy. But the truly wise man will always
make himself contented with his lot in life, and, therefore he
may justly be considered happy. Keynes.
2. Suffering is a title to an excellent inheritance; for God
chastens every son whom he receives. Keynes.
3. No young man is wise; for only experience can give wisdom, and
experience comes only with age. Keynes.
4. Dr. Johnson remarked that “a man who sold a penknife was not
necessarily an iron-monger.” Against what logical fallacy was
this remark directed? Explain. Keynes.
5. This pamphlet contains seditious doctrines, the spread of
which may be dangerous to the state; hence the pamphlet must
be suppressed. Keynes.
6. Good workmen do not complain of their tools: my pupils do not
complain of their tools; therefore, my pupils are probably good
workmen. Keynes.
7. Knowledge gives power; consequently, since power is desirable,
knowledge is desirable. Keynes.
8. Some who are truly wise are not learned; but the virtuous alone
are truly wise; the learned, therefore, are not always virtuous.
Keynes.
9. The spread of education among the lower orders will make them
unfit for their work; for it has always had that effect on those
among them who happen to have acquired it in previous times.
Keynes.
10. Slavery is a natural institution and therefore ought not to be
abolished. Russell.
11. The yardstick of success is the dollar, and you have made your
millions.
12. “All who talk well are not necessarily intelligent, and A is
certainly a spell-binder.”
13. Gold and silver are the wealth of a country; consequently,
the diminution of gold and silver by exportation must mean the
diminution of the wealth of a country. Russell.
14. A miracle is unbelievable, because it fails to conform to known
laws of nature.
15. Improbable events happen every day; now, what happens every day
is a probable event; therefore, improbable events are probable
events.
16. What fallacy did Columbus commit when he made the egg stand on
end by breaking one end?
17. Some holder of a ticket is sure to draw the prize; and, as I am
a ticket holder, I am sure to draw the prize. Russell.
18. All the members of the jury are just men, hence you may trust the
foreman.
