In all that is here suggested concerning their little use for the improvement of knowledge, or dangerous use in undetermined ideas, I have been far enough from saying or intending they should be laid aside; as some have been too forward to charge me.

I affirm them to be truths, self-evident truths; and so cannot be laid aside.

As far as their influence will reach, it is in vain to endeavour, nor will I attempt, to abridge it.

But yet, without any injury to truth or knowledge, I may have reason to think their use is not answerable to the great stress which seems to be laid on them; and I may warn men not to make an ill use of them, for the confirming themselves in errors.] 15.

They cannot add to our knowledge of Substances, and their Application to complex Ideas is dangerous.
But let them be of what use they will in verbal propositions, they cannot discover or prove to us the least knowledge of the nature of substances, as they are found and exist without us, any further than grounded on experience.
