Marks of verbal Propositions, First, Predication in abstract.
      §12. To conclude, barely verbal Propositions may be known by
these following Marks:
      First, All Propositions, wherein two abstract Terms are affirmed
one of another, are barely about the signification of Sounds. For
since no abstract Idea can be the same with any other but it self,
— 617 —
when its abstract Name is affirmed of any other Term, it can signify
no more but this, that it may, or ought to be called by that Name;
or that these two Names signify the same Idea. Thus should any
one say, that Parsimony is Frugality, that Gratitude is Justice; that
this or that Action is, or is not Temperance: However specious these
and the like Propositions may at first sight seem, yet when we
come to press them, and examine nicely what they contain, we shall
find, that it all amounts to nothing, but the signification of those
Terms.
