Judgment supplies the want of Knowledge.
      §3. The Faculty, which God has given Man to supply the want
of clear and certain Knowledge in Cases where that cannot be had,
is Judgment: whereby the Mind takes its Ideas to agree, or disagree;
or which is the same, any Proposition to be true, or false, without
perceiving a demonstrative Evidence in the Proofs. The Mind
sometimes exercises this Judgment out of necessity, where demon-
strative Proofs, and certain Knowledge are not to be had; and
sometimes out of Laziness, Unskilfulness, or Haste, even where
demonstrative and certain Proofs are to be had. Men often stay not
warily to examine the Agreement or Disagreement of two Ideas,
which they are desirous, or concerned to know; but either in-
capable of such Attention, as is requisite in a long Train of Grada-
tions, or impatient of delay, lightly cast their Eyes on, or wholly
pass by the Proofs; and so without making out the Demonstration,
determine of the Agreement or Disagreement of two Ideas, as it
were by a view of them as they are at a distance, and take it to
be the one or the other, as seems most likely to them upon such
a loose survey. This Faculty of the Mind, when it is exercised
immediately about Things, is called Judgment; when about Truths
delivered in Words, is most commonly called Assent or Dissent:
which being the most usual way, wherein the Mind has occasion to
employ this Faculty, I shall under these Terms treat of it, as least
liable in our Language to Equivocation.
