Human Nature is indeed a wonderful Composure admirable in its outward structure, but much more excellent in the Beauties of its Inward, and she who considers in whose Image her Soul was Created, and whose Blood was shed to Redeem it, cannot prize it too much, nor forget to pay it her utmost regard. There’s nothing in this Material World to be compar’d to’t, all the gay things we dote on, and for which we many times expose our Souls to ruin, are of no consideration in respect of it. They are not the good of the Soul, its happiness depends not on ’em, but they often deceive and withdraw it from its true Good. It was made for the Contemplation and Enjoyment of its GOD, and all Souls are capable of this tho in a different degree and by measures somewhat different, as we hope will appear from that which follows. §. I. Truth in general is the Object of the Understanding, but all Truths are not equally Evident, because of the Limitation of the Humane Mind, which tho’ it can gradually take in many Truths, yet cannot any more than our sight attend to many things at once: And likewise, because GOD has not thought fit to communicate such Ideas to us, as are necessary to the disquisition of some particular Truths. For knowing nothing without us but by the Idea we have of it, and Judging only according to the Relation we find between two or more Ideas, when we cannot discover the Truth we search after by Intuition or the immediate companion of two Ideas, ’tis necessary that we shou’d have a third by which to compare them. But if this middle Idea be wanting, though we have sufficient Evidence of those two which we wou’d compare, because we have a Clear and Distinct Conception of them, yet we are Ignorant of those Truths which wou’d arise from their Comparison, because we want a third by which to compare them.
