Arguments Containing Inverted Propositions.
(7) “Blessed are the merciful: for they shall obtain mercy.” The first proposition, being poetical in construction,is typical of the inverted form. These are usually made logical by simple conversion. Since premises usually follow “for,” or equivalent word-signs, it is easy to see that “for they shall obtain mercy” is one of the premises; while the other, the broader of the two, is understood.
Arranged logically the argument assumes this form:
A Those who M
obtain mercy are G
blessed,
A The S
merciful shall M
obtain mercy,
A ∴ The S
merciful are G
blessed.
Here we have the mood
A
A
A in the first figure, which we know to be valid.
