1. Necessary to know their boundaries.
It has been above shown, 1. That we are of necessity ignorant, and want
knowledge of all sorts, where we want ideas. 2. That we are ignorant, and want rational knowledge, where we
want proofs. 3. That we want certain knowledge and certainty, as far as we want clear and determined specific
ideas. 4. That we want probability to direct our assent in matters where we have neither knowledge of our own nor
testimony of other men to bottom our reason upon.
From these things thus premised, I think we may come to lay down the measures and boundaries between faith
and reason: the want whereof may possibly have been the cause, if not of great disorders, yet at least of great
disputes, and perhaps mistakes in the world. For till it be resolved how far we are to be guided by reason, and how
far by faith, we shall in vain dispute, and endeavour to convince one another in matters of religion.
