[Arisbe] Re: Logic As Semiotic

| We found representations to be of three kinds
|
| Signs   Copies   Symbols.
|
| By a 'copy', I mean a representation whose agreement with
| its object depends merely upon a sameness of predicates.
|
| By a 'sign', I mean a representation whose reference to
| its object is fixed by convention.
|
| By a 'symbol', I mean one which upon being presented to the mind --
| without any resemblance to its object and without any reference to
| a previous convention -- calls up a concept.  I consider concepts,
| themselves, as a species of symbols.
|
| A symbol is subject to three conditions.  First it must represent an object,
| or informed and representable thing.  Second it must be a manifestation of
| a 'logos', or represented and realizable form.  Third it must be translatable
| into another language or system of symbols.
|
| The science of the general laws of relations of symbols to logoi is general grammar.
| The science of the general laws of their relations to objects is logic.  And the
| science of the general laws of their relations to other systems of symbols is
| general rhetoric.
