Following the ghosts is about making a contact that changes you and refashions the social relations in which you are located. It is about putting life back in where only a vague memory or a bare trace was visible to those who bothered to look
What is remembering? Remembering brings the absent into the present, connects what is lost to what is here. Remembering draws attention to lostness and is made possible by emotions of space that open backward into a void. Memory depends upon void, as void depends upon memory to think it. Once void is thought, it can be canceled. Once memory is thought, it can be commodified.
-Anne Carson Economy of the Unlost.
