Perhaps this is a broad stroke of a linguistic brush here, but upon reading, I was inspired by the artists' endeavors to reinvent art definitions. Nevertheless, I find it difficult to abolish the author, as what is implied in Postproduction. Roland Barthes was too reactive to embrace the autonomy of readers. Foucault's assessment of writing as a form of immortality (although altered in the 20th century to the sacrifice of the author) I believe still holds true with authorship and art. Is art an artifact of the human species that the species wants to remain, after possible extinction? Moreover, although I praise the artists mentioned in the book, there were some practices I found questionable, perhaps because it is absurd in writing.
I may modify this post. I think I need to develop this more coherently. Consider it a flash of light to emit a little longer.
