The book named How We Became Posthuman, and the author is Katherine Hayles. In this altogether fascinating volume, Katherine Hayles explores the history of cybernetic theory concerning its cultural dissemination primarily in literature. Developing lucid, and remarkably concise, historical reconstructions of the origins of cybernetics at the famous Macy Conferences, Hayles assesses the unfolding of a ‘post-human’ logic that has become pervasive in information theory, artificial intelligence, and even the humanities. Although she is not entirely critical of this development, she is critical of the cyberneticist abandonment of embodiment. While I agree with the general direction of this disagreement, her reasoning is often tendentious and underdeveloped. A fuller, more robust theory of representation and in its interactions with cognition would be needed.
