Stuff/objects are not just totems or trinkets
They are the primary means we have for interacting with the world outside ourselves, and if we can comprehend nonbiological external things or technologies as being *part* of ourselves, then they are clearly the primary method for tangibly making ourselves *part* of the world. All living and nonliving objects part of the same universe, as a selfless or self-integrated principle of aspiration.
I have a coffee cup, that I bought on the Internet from a pizza shop in Connecticut, printed with their image and contact information, to fondly remember a place where my wife and I had a very nice and meaningful meal early in our relationship.
To me, this is not a nostalgia object. It is a representation and an example of how we (quite literally) navigate the world and place ourselves into it.
How we build/attain/interact with these things, these tools, these objects of intense expression of ourselves, pieces of ourselves … these elements of the material nonliving world that we invite into our homes and our selves … that process of selection and choices is elemental to understanding who we are and have always been.
We are cyborgs, in the sense that we use and deeply/inextricably depend on technology, but we always have been. It’s one of the main distinguishing and distinctive things about us as people (maybe *the* thing that defines a person?). Adept creation and use of tools to mediate the world and our selves is a major sign we’re aware of our surroundings, that we are distinct from those surroundings, but that we also want to be a part of that world, and to be it ourselves. To repair our separation from it.
