Negri then seeks to define artistic beauty in this new era, and this he does in terms of concepts that have become fundamental to his thinking - singularity, multitude, abstraction, collective work, event, the biopolitical, the common. Art is living labour, and therefore invention of singularity, of singular figures and objects. But this expressive act only achieves beauty when the signs and language through which it expresses itself turn themselves into community, when they are contained within a common project. The beautiful is not the act of imagining, but an imagination that has become action. Art, in this sense, is multitude.
