Seems to me that the pragmatic maxim answers the question whether we individuals are signs, whether human being and words are identical. Everything we think or sense, when it becomes conscious, becomes something else. It collides with a confining element. In some cases it is a word itself that confines what was an amorphous something. The pragmatic maxim says that it is the end result of the triadic process that can be said to be the whole of it. That end is an action in the form of a conclusion or intention or an actual doing of something. If this is correct the identity is not between man and word, Word is a utility like will that assists in the process of moving from sign icon through index to symbol which is the third and which in this sense is the whole matter. I append my usual thought - but what do I know?
