This paper will approach the New Realism, a philosophical movement which is little by little gaining popularity. First, a brief analysis of its origin will be made. Next, it will focus on four of the main theories of this movement, the ones from: Quentin Meillassoux, Graham Harman, Maurizio Ferraris and Markus Gabriel. The reason of doing that is to find the similarities and differences between all of them, in order to stablish a more accurate classification inside the New Realism.
