Activity theory doesnt seem to have an ontology of its own.-- E. Lagache.
Could you tell me who you are citing?
I am unclear about who inherits one (an ontology), the social mileu.
Could you help me out by going to some texts:
Leontiev, Rubensthein, and Engestrom (or people referenced with approval
by Engetrom) would help orient me a lot.
