TRUTH, yeritas,aTcvm us'd in Opposition to FalJhcod\ and apply'd to Propofitions which anfwer or accord to the Nature and Reality of the Thing whereof fortieth ing is af- firm'd, or deny'd. See Proposition, Jjfc. ■ Thus, when we fay that 4 is the fourth Part of twice 8 5 that Proportion is true, becaufc agreeable to the Nature of thofe Numbers. See Falsiiood.
Truth, according to Mr. Loc\, confifts in the joining or feparating of Signs as the Things fignify'd by them d.) agree or difasree one with another. — Now the joining or feparat- ing of Signs, is what we call making of Propofitions. — Truth then, properly, belongs only to Propofitions, whereof there are two Sorts, mental and verbal ; as there are two Sorts of Signs commonly made ufe of, yi&. Ideas and Words. See Idea and Word.
Mental 'Propofitions, are thofe wherein the Ideas in our Underftanding are put together, or feparatcd by the Mind perceiving or judging of their Agreement or Difagree- ment.
Verbal 'Propofitions, are Words put together, or Separated, in affirmative or negative Sentences : — So that Proposition confifts in joining or feparating Signs ; and Truth confifts in putting together or Separating thofe Signs, according as the Things they {land for agree or difagree.
Truth, therefore, as well as Knowledge, may come under the Diftinclion of verbal and real j that being only -verbal Truth, where Terms are join'd according to the Agreement or Disagreement of the Ideas they Stand for, without regard- ing whether our Ideas are fuch as really have, or are capable of having any Exiftence in Nature. — But it is then they contain real Truth, when thefe Signs are join'd as our Idea's agree ; and when our Ideas are fuch, as we know are capable of having an Exiftence in Nature; which in Subftances we cannot know, but by knowing that fuch have exifted. See
SURSTANCE.
Truth is the marking down in Words the Agreement or Difagreement of Ideas, as it is. — Falfhocd is the marking down in Words the Agreement or Difagreement of Ideas othcrwife than it is ; and fo far as thefe 'ideas, thus mark'd by Sounds, agree to their Archetypes, fo far only is the Truth real.
The Knowledge of this Truth confifts in knowing what Ideas the Words Stand for, and the Perception of the Agree- ment or Difagreement of thofe Ideas, 'according as 'it is mark'd by thofe Words. See Probability Evidence
Eefides Truth taken in the {trict Senfe before mention'd which is alfo call'd Logical Truth, there are other Sorts of Truths ; as,
i°. Moral Truth, which confifts in fpeaking Things ac- cording to the Perfuafion of our own Minds 5 call'd alfo Ve- racity.
