This dissertation aims to shed light over the poetic writing of Charles Bukowski through its relation with Nietzsche s tragic philosophy, which, in its turn, follows the guidance of Deleuze s Nietzsche and Philosophy. This approach between the poet s activity and the philosophers thought holds up based on the common references provided by the concepts of force, body, will, power and art. Thus, this dissertation s analytical perspective differs from the biographical and self-fictional notions normally assigned to Bukowski — where his writing is reactively assessed by the categories of metaphor, antithesis and representation — to depart from a both active and paradoxical point of view that takes his poetry as a concrete symptom of the artist s will, which is conceived by the developments of the force-body tensions proposed by Nietzsche. From the becomings imposed by such tension of forces, the research will follow the metamorphosis in the art of Bukowski as a symptom of a body at times engaged in the radical experiences of a nihilism that affirms the denial, sometimes manifesting Dionysus double affirmation: art as a power of the difference, as the power that affirms the affirmation.
