International scholars explore the ways in which knowledge actually operates, showing the limitations of now outmoded disciplines. Coming from fields as diverse as anthropology, philosophy, literature, aesthetics and art practice, together they break down the boundaries between entrenched domains of knowledge. Studies of objects which confound traditional definitions – including a mechanical cow invented by an Irish farmer, and the curious case of a mechanical monk – show how a close look at an individual object can, paradoxically, open up dynamic new "reconceptions" of traditional systems of knowledge. With social uses of knowledge currently a matter of public debate, this should be a timely text.
