On page 170, Butler (citing Freud) distinguishes between melancholia and mourning: in mourning, the object is "declared" lost, but in melancholia, no declaration is possible. Melancholia therefore paves the way for mourning.
Butler repeatedly asks how a subject could internalize lost attachment to an object prior to the constitution of interior/exterior distinctions. I guess I'm not sure about Butler's relationship to Freud: did Freud give melancholy its founding, originary role, or did he conceive of it as one possible psychic phenomenon among many? Is the paradox Butler seizes on inherent to Freud, or is it the result of her own understanding of melancholy as the founding turn of subjectivation?
I have always been kind of skeptical of psychoanalysis in general and Freudian analysis specifically, but a couple of statements seemed to ring true to me in the reading.
