But if propositions be brought to him in words which stand for ideas he has not yet in his mind, to such propositions, however evidently true or false in themselves, he affords neither assent nor dissent, but is ignorant.
For words being but empty sounds, any further than they are signs of our ideas, we cannot but assent to them as they correspond to those ideas we have, but no further than that.

But the showing by what steps and ways knowledge comes into our minds; and the grounds of several degrees of assent, being; the business of the following Discourse, it may suffice to have only touched on it here, as one reason that made me doubt of those innate principles.

Not innate because not universally assented to.
To conclude this argument of universal consent, I agree with these defenders of innate principles,--that if they are innate, they must needs have universal assent.

For that a truth should be innate and yet not assented to, is to me as unintelligible as for a man to know a truth and be ignorant of it at the same time.

But then, by these men's own confession, they cannot be innate; since they are not assented to by those who understand not the terms; nor by a great part of those who do understand them, but have yet never heard nor thought of those propositions; which, I think, is at least one half of mankind.
