Quote from ‘Notes on Topical Geometry’

Term: 
Index
Quote: 

Signs are of three kinds,

1st, the icon, which represents its object by virtue of a character which it would equally possess did the object and the interpreting mind not exist;

2nd, the index, which represents its object by virtue of a character which it could not possess did the object not exist, but which it would equally possess did the interpreting mind not operate;

3rd, the symbol, which represents its object by virtue of a character which is conferred upon it by an operation of the mind.

[—]

An index represents an object by virtue of its connection with it. It makes no difference whether the connection is natural, or artificial, or merely mental.
