On to the next section: Barthes begins to discuss writing. He moves then from writing to language itself. And he acknowledges the difficulty in his work: "He realizes then how obscure such statements, clear as they are to hum, must be for many others." (80)
"You constitute yourself": Barthes is speaking to himself here, and he precedes this statement with "worse still." (82) To be fixed seems not the ideal state for Barthes, and the account of his schedule does this to him (as does the book itself, no?). What, then, of photography? Does it also constitute the subject?
He speaks of film in a way that can be applied to photography: "here the image is the irremediable absence of the represented body." (84) irremediable = untreatable, incurable.
Note to self: he mentions "post-meaning" on p.87 - the absence of every sign.
He continues and accounts the practice of fragments (92-94). "One writes in order to be loved": another phrase destined for a t-shirt or Facebook status update. (104)
We see much of Barthes as a person in these sections (for instance, his afternoon snack of sugar in cold milk - I'm going to try this today in honour); these are personal images, but the fragments do not absolutely constitute the writer. We don't really know him. He is too slippery here (he talks a lot about the "drift" of writing - like a ghost, he drifts here as well).
I found this section quicker to read, maybe because I found (today, now) less to write down, less directly applicable to our discussions (on photography, or on less complex ideas in Barthes' oeuvre).
In any case, your mileage may vary.
