The Third Mind is a book by Beat Generation novelist William S. Burroughs and artist/poet/novelist Brion Gysin.

It contains numerous short fiction pieces as well as poetry by Gysin, and an interview with Burroughs.

The book is a combination of literary essays and writing showcasing the cut-up technique popularized by Burroughs and Gysin in the 1960s.

Cut-ups involves taking texts, cutting the pages, and then rearranging and combining the pieces to form new narratives.

The technique was adapted for filmmaking, as demonstrated by Burroughs and director Antony Balch in their early 1960s short film, The Cut-Ups.
