sider Truth of Thought, and Truth of Words, distinctly one from
another: but yet it is very difficult to treat of them asunder. Because
it is unavoidable, in treating of mental Propositions, to make use
of Words: and then the Instances given of Mental Propositions, cease
immediately to be barely Mental, and become Verbal. For a mental
Proposition being nothing but a bare consideration of the Ideas, as
they are in our Minds stripp’d of Names, they lose the Nature of
purely mental Propositions, as soon as they are put into Words.
