Physical horizons

Horizons beyond set paths

Wider possibilities for action and being

Uncontrolled extension

What something is revealed to be, what it means, depends on the horizon of possibilities (actions, inferences, things it might have been or done, etc.) within which it stands in contrasts. Explicit hypertext links are part of that standing within the horizon, but the items a text chunk or a region of a place are linked to are surrounded by more than explicit links. We can distinguish a variety of horizons for a thing, for a text, for a hypertext, for a suburban building, or for part of any place:

All these help constitute the contour of meaning surrounding this text or this place or this action, as a relatively definite perspectival construct out of surrounding possibilities. But there are always other possible routes toward wider horizons.
