Probably the most common enthymemes are those of the first order. This may be explained by the fact that the major premise is usually the most universal of the three propositions, and, in consequence, the one which would be the most generally understood. The following represent enthymemes of this order, gleaned from the ordinary conversation of ordinary people:
(1) “Your beets won’t grow, because you are planting them in the wrong time of the moon.”
(2) “You, being a member of the Sunday School, should be ashamed of such language.”
(3) “Being the son of your father, you ought to have some pride in this matter.”
(4) “We are going to have an open winter, because I have observed that the hornets’ nests are near the ground.”
(5) “You had better put in lots of coal, for I have noticed that the squirrels have gathered in more nuts than usual.”
Judging from these enthymemes, it would seem to be more natural to assert the conclusion and follow this bya reason in the form of a minor premise, leaving the major to the intelligence of the auditor.
The enthymeme of the second order occurs only infrequently, since it seems to be an unnatural mode of expression, though sometimes it appears to lend emphasis to the conclusion; e. g., “All untrustworthy boys come to a bad end, and I predict that you will come to a bad end.”
Enthymemes of the third order are commonly used for the sake of emphasis, as the following make evident:
(1) “No business man wants an indolent boy, and you are indolent.”
