Modern philosophical text

The 20th century was filled with many philosophers who contributed their philosophical, intellectual, and cognitive output, and some of them formed philosophical currents whose existence was active and influential in the intellectual arena, leaving behind a philosophical heritage from which many drew. Among these philosophers is Gilles Deleuze, who was classified within the postmodernist stage and influenced by the Nietzschean current, which also influenced other philosophers such as Michel Foucault, Jacques Derrida, and others, all of whom Nietzsche was their inspiration and guide. Each of them has his own philosophical system that represents his orientations and opinions, after philosophy fragmented and moved away from comprehensive doctrines and schools.
