2. Answer: "Not so, where ideas agree with things.
To which I answer, That if our knowledge of our ideas
terminate in them, and reach no further, where there is something further intended, our most serious thoughts will
be of little more use than the reveries of a crazy brain; and the truths built thereon of no more weight than the
discourses of a man who sees things clearly in a dream, and with great assurance utters them. But I hope, before I
have done, to make it evident, that this way of certainty, by the knowledge of our own ideas, goes a little further
than bare imagination: and I believe it will appear that all the certainty of general truths a man has lies in nothing
else.
