The Matrix trilogy continues to split opinions widely, polarising the downright dismissive and the wildly enthusiastic. Nevertheless, it has been fully embraced as a rich source of theoretical and cultural references. The contributions in this volume probe the effects the Matrix trilogy continues to provoke and evaluate how or to what extent they coincide with certain developments within critical and cultural theory. Is the enthusiastic philosophising and theorising spurred by the Matrix a sign of the desperate state theory is in, in the sense of “see how low theory (or ‘post-theory’) has sunk”? Or could the Matrix be one of the “master texts” for something like a renewal for theory as now being mainly concerned with new and changing relations between science, technology, posthumanist culture, art, politics, ethics and the media? The present volume is unashamedly but not dogmatically theoretical even though there is not much agreement about what kind of theory is best suited to confront “post-theoretical” times. But it is probably fair to say that there is agreement about one thing, namely that if theory appears to be “like” the Matrix today it does so because the culture around it and which “made” it itself seems to be captured in some kind of Matrix. The only way out of this is through more and renewed, refreshed theorising, not less.
