hey be equal or no; because their agreement or
disagreement in equality can never be perceived by an immediate
comparing them: the difference of figure makes their parts incapable
of an exact immediate application; and therefore there is need of some
intervening qualities to measure them by, which is demonstration, or
rational knowledge.

4. Fourthly, Nor does Demonstrative Knowledge.

Fourthly, It follows, also, from what is above observed, that our
RATIONAL KNOWLEDGE cannot reach to the whole extent of our ideas:
because between two different ideas we would examine, we cannot always
find such mediums as we can connect one to another with an intuitive
knowledge in all the parts of the deduction; and wherever that fails, we
come short of knowledge and demonstration.

5. Fifthly, Sensitive Knowledge narrower than either.

Fifthly, SENSITIVE KNOWLEDGE reaching no further than the existence of
things actually present to our senses, is yet much narrower than either
of the former.

6. Sixthly, Our Knowledge, therefore narrower than our Ideas.

Sixthly, From all which it is evident, that the EXTENT OF OUR KNOWLEDGE
comes not only short of the reality of things, but even of the extent of
our own ideas. Though our knowledge be limited to our ideas, and cannot
exceed them either in extent or perfection; and though these be very
narrow bounds, in respect of the extent of All-being, and far short
of what we may justly imagine to be in some even created understandings,
not tied down to the dull and narrow information that is to be received
from some few, and not very acute, ways of perception, such as are our
senses; yet it would be well with us if our knowledge were but as large
as our ideas, and there were not many doubts and inquiries CONCERNING
THE IDEAS WE HAVE, whereof we are not, nor I believe ever shall be in
this world resolved. Nevertheless, I do not question but that
human knowledge, under the present circumstances of our beings and
constitutions, may be carried much further than it has hitherto been, if
men would sincerely, and with freedom of mind, employ all that industry
and labour of thought, in improving the means of discovering truth,
which they do for the colouring or support of falsehood, to maintain a
system, interest, or party they are once engaged in. But yet after all,
I think I may, without injury to human perfection, be confident,
that our knowledge would never reach to all we might desire to k
