| 4. Semantical Rules (cont.)
|
| It may be instructive to compare the notion of semantical rule with that
| of postulate. Relative to a given set of postulates, it is easy to say
| what a postulate is: it is a member of the set. Relative to a given
| set of semantical rules, it is equally easy to say what a semantical
| rule is. But given simply a notation, mathematical or otherwise,
| and indeed as thoroughly understood a notation as you please in
| point of the translations or truth conditions of its statements,
| who can say which of its true statements rank as postulates?
| Obviously the question is meaningless -- as meaningless as
| asking which points in Ohio are starting points. Any finite
| (or effectively specifiable infinite) selection of statements
| (preferably true ones, perhaps) is as much 'a' set of postulates
| as any other. The word "postulate" is significant only relative
| to an act of inquiry; we apply the word to a set of statements just
| in so far as we happen, for the year or the moment, to be thinking of
| those statements in relation to the statements which can be reached from
| them by some set of transformations to which we have seen fit to direct our
| attention. Now the notion of semantical rule is as sensible and meaningful as
| that of postulate, if conceived in a similarly relative spirit -- relative, this
| time, to one or another particular enterprise of schooling unconversant persons
| in sufficient conditions for truth of statements of some natural or artificial
| language L. But from this point of view no one signalization of a subclass
| of the truths of L is intrinsically more a semantical rule than another;
| and, if "analytic" means "true by semantical rules", no one truth of L
| is analytic to the exclusion of another.*
