This book offers a much-needed new political theory of an old phenomenon. The last decade alone has marked the highest number of migrations in recorded history. Constrained by environmental, economic, and political instability, scores of people are on the move. But other sorts of changes - from global tourism to undocumented labor - have led to the fact that to some extent, we are all becoming migrants. The migrant has become the political figure of our time. 

We live in an age of the mobile image. This recent kinetic revolution of the image has enormous consequences not only for the way we think about contemporary art and aesthetics but also for art history as well. Responding to this historical moment, Theory of the Image offers a fresh new theory and history of art from the perspective of this epoch-defining mobility. The image has been understood in many ways, but it is rarely understood to be fundamentally in motion.

As this book argues, every era since Marx's death has reinvented him to fit its needs. There is not one Marx forever and for all time. There are a thousand Marxes. As Thomas Nail contends, one of the most significant contributions of Marx's work is that it treats theory itself as a historical practice. Reading Marx is not just an interpretative activity, but a creative one. As our historical conditions change, so do the kinds of questions we pose and the kinds of answers we find in Marx's writing. 

We need a new philosophy of the earth. Geological time used to refer to slow and gradual processes, but today we are watching land sink into the sea and forests transform into deserts. We can even see the creation of new geological strata made of plastic, chicken bones, and other waste that could remain in the fossil record for millennia or longer. Crafting a philosophy of geology that rewrites natural and human history from the broader perspective of movement, Thomas Nail provides a new materialist, kinetic ethics of the earth that speaks to this moment.

Henri Bergson (1859-1941) was the leading French philosopher of the first half of the 20th century. Near the end of his life when he was forced to register with the police in Nazi occupied France he wrote: ‘Academic. Philosopher. Nobel prize winner. Jew.’ Time and Free Will, his doctoral thesis, was published as a book in 1889 and attacks and rejects the mechanistic view of causality described in Kant’s version of space and time and proceeds to attempt to define free-will and consciousness by separating space and time.
