So, there are a number of things I am actually after with this, but to try to encapsulate the concern briefly: which thinkers or writers might comment on the relationship between animals and human beings?
In particular, I am concerned about the meaning of a certain "non-relation" that our habitual relations with animals tends towards, a gap between animals and human beings; perhaps particularly within the context of the history of philosophy.
I have been reading and enjoying the recently translated Two Lessons on Animal and Man by Gilbert Simondon; I am also planning on working through Derrida's The Beast and the Sovereign. (I have also been considering trying to read Agamben's Homo Sacer, and perhaps Guattari's Three Ecologies, alongside these.)
While I would be interested in finding out about any works that might help supplement the study, anything from critical animal studies to deconstructionist/schizoanalytic approaches to the general question, I would definitely love to discover a robust critical study of the animal-human relation in Western thought/letters.
