The goal of my essay is to clarify the status of the a priori in Hegel's Science of Logic. My claim is that in order to make possible an appreciation of the originality of Hegel's position we need to map a context of discussion and to dissolve a set of preconceptions about Hegel's idea of philosophy. My argument will be articulated in two parts. In the first part, I will analyse four possible positions regarding the issue of the aprioricity of (...) the Logic, I will defend a fifth position, and I will draw a distinction between apriorism and a priori. In the second part, I will examine three distinct charges of apriorism against Hegel's Logic: the charge of assuming God's point of view of the universe, the charge of vicious circularity between the beginning and the end of the Logic, the charge of self-sufficiency of the Logic. As a result, I hope to show that these charges are unfounded, and to clear the ground for an adequate evaluation of Hegel's own sublation of the a priori/a posteriori divide. (shrink)

Resumo O objetivo de meu trabalho é o esclarecimento de quatro características distintivas do sistema hegeliano como projeto de uma filosofia livre de pressuposições. Para tanto, pretendo reconstruir a conexão entre os seguintes traços constitutivos do conceito operativo de Voraussetzungslosigkeit : em primeiro lugar, a imanência do real ao pensar objetivo; em segundo, a integração do ceticismo pirrônico ou antigo ao modo de apresentação científica do pensar; em terceiro lugar, a configuração do elemento lógico em termos de um movimento de (...) circulação de si mesmo; em quarto, a subversão da compreensão ordinária da dupla conceitual "abstrato-concreto". A reconstrução assim oferecida permite argumentar sobre conclusões relevantes para compreender adequadamente a ambição do projeto especulativo de Hegel: em primeiro lugar, a ausência de pressuposições só pode confirmar-se enquanto prova científica por meio da subversão das certezas arraigadas no senso comum; em segundo, a prova da imanência é científica na medida em que mostra o necessário entrelaçamento do aspecto ontológico com o aspecto epistemológico do sistema, tornando-o invulnerável a objeções céticas de tipo radical; em terceiro, o sistema não é de modo algum reduzível à estrutura da Enciclopédia, pois essa é apenas um auxílio didático para a apresentação do sistema, cujo significado verdadeiro pode ser atingido unicamente pela organização cada vez mais concreta dos silogismos da ideia da filosofia.The aim of my article is the clarification of four distinctive characters of Hegel's system as a project of a presuppositionless philosophy. For this purpose, I will reconstruct the connection among the following features of the operative concept of presuppositionlessness: in the first place, the immanence of the real in the objective thinking; in the second place, the integration of pyrrhonian or ancient skepticism into the scientific way of presentation of thinking; in the third place, the configuration of the logical element in terms of an inner circulation; in the fourth place, the subversion of the ordinary understanding of the couple 'abstract-concrete'. This reconstruction allows me to argue for some conclusions relevant for the understanding of the ambitions of the Hegelian speculative project. In the first place, presuppositionlessness can be confirmed as a scientific proof only if the subversion of the commonsensical distinctions between abstract and concrete succeeds. In the second place, the proof of the immanence is scientific insofar as it shows the necessary intertwinement of the ontological aspect with the epistemological aspect of the system, making it invulnerable to radical skeptical objections. In the third place, the system is by no means reducible to the structure of the Encyclopedia, since this is only a didactic support for the presentation of the system, whose true meaning can be attained only by the more and more concrete organization of the syllogisms of the idea of philosophy.

O objetivo do meu artigo é apresentar a relação todo-partes no contexto da Doutrina da Essência de Hegel. Depois de ter indicado sucintamente a variedade de contextos em que essa relação ainda está debatida hoje em dia, tanto fora como dentro da interpretação da filosofia hegeliana, analisarei o contexto específico da primeira subdivisão do terceiro capítulo da segunda seção da obra referida, analisando o argumento do texto e contextualizando o significado da Observação anexa. A relevância deste ensaio consiste em promover (...) uma compreensão precisa de um par conceitual usado muitas vezes como um passe-partout hermenêutico para defender ou combater a filosofia de Hegel com base na suposta defesa hegeliana da primazia do todo sobre as partes. A tese da lógica da essência é que tanto a primazia das partes sobre o todo como a primazia do todo sobre as partes são posições insustentáveis. Por fim, o argumento para essa tese envolverá um exame contextual da segunda antinomia da Crítica da Razão Pura. (shrink)

The aim of this article is to discuss the objection of vicious circularity concerning the relation between the Phenomenology of Spiritand the Science of Logic. My argument is articulated in three stages: in the first place, I will provide a historical reconstruction of the debate and I will try to neutralize the objection of vicious circularity; in the second place, I will examine the latest positions of the Hegel-Forschungabout the issue of a possibly reciprocal presupposition between the PhG and the (...) SL; in the third place, I will analyze the meaning of a virtuous circularity, by showing its inner relation to a dynamic conception of systematicity. (shrink)

The use of assistance systems aimed at reducing road fatalities is spreading, especially for car drivers, but less effort has been devoted to developing and testing similar systems for powered two-wheelers. Considering that over speeding represents one of the main causal factors in road crashes and that riders are more vulnerable than drivers, in the present study we investigated the effectiveness of an assistance system which signaled speed limit violations during a simulated moped-driving task, in optimal and poor visibility conditions. (...) Participants performed four conditions of simulated riding: one baseline condition without Feedback, one Fog condition in which visual feedback was provided so as to indicate to the participants when a speed limit was exceeded, and two post-Feedback conditions with and without Fog, respectively, in which no feedback was delivered. Results showed that participants make fewer speeding violations when the feedback is not provided, after 1 month, and regardless of the visibility condition. Finally, the feedback has been proven effective in reducing speed violations in participants with an aggressive riding style, as measured in the baseline session. (shrink)
