All tools have histories, which means that any particular person is not free to use them in an arbitrary way, but must use them within
some range of restricted or shared meanings. And so these tools bring with them to any action a pre-established set of limitations. At
the same time, these tools are also altered through their use and thus no use of any cultural tool is absolutely determinant of the social
action that it can be used to perform. Put another way, all cultural tools bring into social action a set of contradictions and
complications, which are the sources of both limitations and of ambiguity, novelty, and creation.
