the symbols are not governed by *natural laws* but by *rules*
I am returning to the themes of activity and meaning.
In the beginning is material substance AS object
the means of *figuring* [out] the symbols [as figures or as interpretations
or meaning or?]
*symbols* which ARE no longer means BUT OBJECT.
Symbols AS object ARE no longer governed by *natural laws* but are now
governed by rules
when a child is playing a rule-governed game.
Where is *meaning* located? Is meaning inherent in ALL these trans
is meaning an aspect of this unit?
