6. Not so clear as intuitive knowledge.
It is true, the perception produced by demonstration is also very clear; yet
it is often with a great abatement of that evident lustre and full assurance that always accompany that which I call
intuitive: like a face reflected by several mirrors one to another, where, as long as it retains the similitude and
agreement with the object, it produces a knowledge; but it is still, in every successive reflection, with a lessening
of that perfect clearness and distinctness which is in the first; till at last, after many removes, it has a great mixture
of dimness, and is not at first sight so knowable, especially to weak eyes. Thus it is with knowledge made out by a
long train of proof.
