THE SIGNS OF SPACE AND TIME

Peircean Philochrony (Charles S. Peirce)

Types of images or signs: icons, indexes and symbols 

- The icon is similar to the object. 
- The index is directly related to the object. 
- The symbol is given by a law or convention. 
- All words are symbols. 

SPACE 

The space (icon)

Coordinate axis (index) 

Dimensions (Index) 

----------------------------> Direction and sense. 

TIME

The Clock (icon and index) 

Calendar (Index) 

The law of the senses (index)

Note that an arrow in the space indicates direction and sense, but in the time indicates only sense.
