McKenzie Wark combines an autobiographical account of her relationship with Kathy Acker with her transgender reading of Acker's writing to outline Acker's philosophy of embodiment and its importance for theorizing the trans experience.

Over the decades readers have found a punk Acker, a feminist Acker, a queer Acker, a kink Acker, and an avant-garde Acker. In Philosophy for Spiders, McKenzie Wark adds a trans Acker.

Wark recounts her memories of Acker (with whom she had a passionate affair) and gives a comprehensive reading of her published and archived works. Wark finds not just an inventive writer of fiction who pressed against the boundaries of gender but a theorist whose comprehensive philosophy of life brings a conceptual intelligence to the everyday life of those usually excluded from philosophy's purview.

As Wark shows, Acker's engagement with topics such as masturbation, sadism, body-building, and penetrative sex are central to her distinct phenomenology of the body that theorizes the body's relation to others, the city, and technology.
