This book demonstrates for the first time how the work of Ludwig Wittgenstein can transform 4E Cognitive Science. In particular, it shows how insights from Wittgenstein can empower those within 4E to reject the long held view that our minds must involve representations inside our heads.

The book begins by showing how proponents of 4E are divided amongst themselves. Proponents of Extended Mind insist that internal representations are always needed to explain the human mind. However, proponents of Enacted Mind reject this claim. Using insights from Ludwig Wittgenstein, the book introduces and defends a new theoretical framework called Structural Enacted or Extended Mind (STEEM). STEEM brings together Enacted Mind and Extended Mind in a way that rejects all talk of internal representations. STEEM thus highlights the anti-representationalist credentials of 4E and so demonstrates how 4E can herald a new beginning when it comes to thinking about the mind.
