<div>Catastrophes ranging from the travesties of financial markets and the explosion of the Deepwater Horizon oil well to the tsunami that struck northern Japan and the levees breaking in New Orleans are examples of the limits of knowledge. Author Randy Martin insists that the expertise erected to prevent these natural and social disasters failed in each case.<br><br>In <i>Knowledge LTD</i>, Martin explores how both the limits of knowledge and the social constructions of culture reflect the way we organize social life in the face of disasters and their aftermath. He examines this crisis of knowledge as well as the social movements that rose up in its wake. Martin not only treats derivatives as financial contracts for pricing risk, but also shows how the derivative works in economic terms, where the very unity of the economy is undone.<br><br><i>Knowledge LTD</i> ultimately points to a more comprehensive reordering of the once separate spheres of economy, polity, and culture. Martin provides a new way of understanding the social significance of the all-pervasive derivative logic.<br></div>
