|
| We have then between the Unity of being
| and the manifold of substance these three
| and only these three universal conceptions
|
|          Reference to a Ground
|          Reference to a Correlate
|    and   Reference to an Interpretant
|
| Reference to a ground is the possession of Quality.
| Double Reference to Correlate and Ground is Relation.
| Triple Reference to Interpretant, Correlate, and Ground --
| is Representation.
|
| Relation is of two kinds -- Equiparance and Disquiparance.
| Representation is of three kinds -- Likeness, Indication
| or Correspondence in fact, and Symbolization.
|
| Equiparance is agreement in a determinate respect;
| Disquiparance a disagreement or an agreement in
| a respect which does not determine the internal
| quality of the related thing.
|
| Thus, an equiparant is a relate whose reference to a ground may
| be prescinded from its reference to a correlate;  in other words
| the ground of equiparance is an internal character.
|
| A disquiparant is a relate whose reference to a ground necessarily
| supposes a reference to a correlate;  in other words the ground of
| disquiparance is an external or relative character -- as greater,
| less, or equal.
| 
| A Representation is either a Likeness, an Index, or a Symbol.
|
| A likeness represents its object by agreeing with it in some particular.
|
| An index represents its object by a real correspondence with it --
| as a tally does quarts of milk, and a vane the wind.
|
| A symbol is a general representation like a word or conception.
