Our Ignorance great.
      §22. Our Knowledge being so narrow, as I have shew’d, it will,
perhaps, give us some Light into the present State of our minds, if
we look a little into the dark side, and take a view of our Ignorance:
which being infinitely larger than our Knowledge, may serve much
to the quieting of Disputes, and Improvement of useful Knowledge;
if discovering how far we have clear and distinct Ideas, we confine
our Thoughts within the Contemplation of those Things, that are
within the reach of our Understandings, and lanch not out into
that Abyss of Darkness (where we have not Eyes to see, nor
Faculties to perceive any thing,) out of a Presumption, that nothing
is beyond our Comprehension. But to be satisfied of the Folly of
such a Conceit, we need not go far. He that knows any thing,
knows this in the first place, that he need not seek long for Instances
of his Ignorance. The meanest, and most obvious Things that come
in our way, have dark sides, that the quickest Sight cannot pene-
trate into. The clearest, and most enlarged Understandings of
thinking Men find themselves puzzled, and at a loss, in every
Particle of Matter. We shall the less wonder to find it so, when we
consider the Causes of our Ignorance, which, from what has been said,
I suppose, will be found to be chiefly these three:
      First, Want of Ideas.
      Secondly, Want of a discoverable Connexion between the Ideas we
have.
      Thirdly, Want of tracing, and examining our Ideas.
