Single Idea 23494

[filed under theme 5. Theory of Logic / G. Quantification / 1. Quantification ]

Full Idea

There are two problems with defining the quantifiers in terms of conjunction and disjunction. The general statements are unspecific, and do not say which things have the properties, and also they can't range over infinite objects.

Gist of Idea

Conjunctive and disjunctive quantifiers are too specific, and are confined to the finite

A Reaction

That is, the universal quantifier is lots of ands, and the existential is lots of ors. If there only existed finite objects, then naming them all would be universal, and the infinite wouldn't be needed.


The 7 ideas from Michael Morris

To count, we must distinguish things, and have a series with successors in it [Morris,M]
Interpreting a text is representing it as making sense [Morris,M]
Discriminating things for counting implies concepts of identity and distinctness [Morris,M]
Counting needs to distinguish things, and also needs the concept of a successor in a series [Morris,M]
Bipolarity adds to Bivalence the capacity for both truth values [Morris,M]
There must exist a general form of propositions, which are predictabe. It is: such and such is the case [Morris,M]
Conjunctive and disjunctive quantifiers are too specific, and are confined to the finite [Morris,M]
