Or, neglecting the unintentional and merely imitative 

 signs as not, properly speaking, signs at all, every kind of 

 intentional sign may be represented diagrammatically as in 

 the illustration opposite. 



Now, thus far we have been dealing with matters of fact 

 concerning which I do not think there can be any question.

 shall now address ourselves.
