The philosophy of Jacques Ranciere reserves an important place to aesthetics. Aesthetics are redefined from a political and ethical point of view, not as a discipline, but rather as a sensible regime. This article aims to approach the basics of aesthetics, their redefinition and their political dimensions, problematizing the multiple problems between politics, ethics and aesthetics, and stressing a critical reading of the Ranciere writing with other perspectives which unify or separate these spheres.
