In this thesis I focus on dismissivism in metaphysics. Some philosophers argue that at least some metaphysical disputes are not substantial, and as a consequence should be dismissed. In this work I restrict my attention to metaphysics and focus on debates about existence and grounding. In particular I am interested in finding out whether there is a difference between the possible options available for dismissing debates about what there is and the possible options available for dismissing debates about what grounds what. I will delve into this in two different steps. First of all I explore the possibility to dismiss debates about what there is, and as a case study I analyse the debate between three-dimensionalism and four-dimensionalism. Secondly I delve into whether it is possible to dismiss debates about what grounds what, thanks to the discussion of another case study, i.e. the debate between tropes ontologies and universals ontologies. It is worth exploring the nature of dismissivism, because it bears on the future of philosophy. If philosophy has to have a future, we have to make sure that at least some disagreements within it are substantial. My conclusions will be that metaphysical debates about what there is can be dismissed for a variety of reasons (semantic, epistemic, ...). I also argue there is no general formula to find out whether a specific debate should be dismissed. On the other hand I argue that debates about what grounds what should be dismissed. I offer two distinct arguments in favour of my claim. Firstly, I argue that disputants are having a verbal dispute when they talk about what grounds what, and thus their disagreement is non genuine. Secondly, I argue that the notion of grounding is underspecified, because it cannot be properly distinguished from causation.

For this, the Triad makes presence in the whole text in many ways: validity, applicability and effectiveness, freedom, equality and fraternity, text, metatext and intratext; territorialization, deterritorialization, and reterritorialization; past, present and future. Aways for the densification, Walking in a spiral, away from a linear historical meaning of law, but in order of consideration of the "minor literature" that permeates society and that is urgent in the relevance of the application of law and its role as a promoter of a creative freedom, overly human / Este trabalho visa, por si só, pois toma vida a partir do momento em que se imprime do ato criativo do pensar, trazer uma perspectiva sobre o direito que subjaz latente na própria vida, vivida pelos seres sensíveis e em eterna mutação, adentrando, principalmente, nas lições de García Maynez e sua teoria dos três círculos, que nos permitirá evocar a integralidade do direito em todas as suas vertentes privilegiando nós, no presente trabalho, a leitura de Gunther Teubner e o seu realismo jurídico, adensada à concepção crítica da ótica compassiva de Theodor Adorno e de Deleuze e o seu ritornelo, sempre com a base sólida e primordial da Teoria do Capitalismo Humanista, essencialmente no principado jushumanista, consoante brilhantemente concebido por Ricardo Hasson Sayeg. Para tanto, a Tríade se faz presente em todo texto de diversas formas: validade, vigência e eficácia; liberdade, igualdade e fraternidade; texto, metatexto e intratexto; territorialização, desterritorialização e reterritorialização; passado, presente e futuro. Sempre pelo adensamento, num caminhar em espiral, longe de uma acepção linear histórica do direito, mas, sim, afim da consideração da ―literatura menor que permeia a sociedade e que se faz urgente na consideração da aplicação do direito e do seu papel enquanto promotor de uma liberdade criadora, demasiadamente humana
