We may have certainty & knowledge without ideas, i.e. without other ideas than the words, and their standing for one idea, i.e. their being to be used indifferently.

It seems to me that we have no certainty about ideas, but only about words. 'Tis improper to say, I am certain I see, I feel, &c. There are no mental propositions [pg 044] form'd answering to these words, & in simple perception 'tis allowed by all there is no affirmation or negation, and consequently no certainty[153].
