Elbow Room: The Varieties of Free Will Worth Wanting (1984) is a book by the American philosopher Daniel Dennett, which discusses the philosophical issues of free will and determinism.
In 1983, Dennett delivered the John Locke Lectures at Oxford on the topic of free will. In 1984, these ideas were published in the book Elbow Room: The Varieties of Free Will Worth Wanting. In this book Daniel Dennett explored what it means for people to have free will. The title, Elbow Room, is a reference to the question: are we deterministic machines with no real freedom of action or do we in fact have some elbow room, some real choice in our behavior?
