    Procura-se identificar algumas das origens históricas do negacionismo, dando ênfase aos seus aspectos filosóficos. Apresenta-se uma revisão de alguns conceitos basilares como os de verdade e episteme, destacando o quanto foram importantes na História das Ideias e na Filosofia Ocidental. Analisa-se, ainda que de forma resumida, o aspecto social da questão, por meio da compreensão da mudança do sujeito e suas relações de trabalho ao longo da História, principalmente no período pós-industrial. Por …Read more

    Within the general discussion of space and its dimensionality, Aristotle's position is of the greatest relevance, as one will have the opportunity to argue and discuss in this article.

    In this article it is shown that a careful analysis of Kant 's Gedanken von der wahren Schätzung der lebendigen Kräfte und Beurtheilung der Beweise leads to a conclusion that does not match the usually accepted interpretation of Kant 's reasoning in 1747, according to which the young Kant supposedly establishes a relationship between the tridimensionality of space and Newton's law of gravitation. Indeed, it is argued that this text does not yield a satisfactory explanation of space dimensionalit…Read more

    L'idea di relazionare la dimensionalità dello spazio ad una legge fisica, contenuta nel primo scritto di Kant "Pensieri sulla veridica estima delle forze vive", svela un modo di guardare i rapporti tra Fisica e Matematica così nuovo ed originale che potè essere sviluppato e compreso nella sua plenitudine soltanto nel secolo XX. Ci riferiamo qui ala prospettiva aperta da Ehrenfest nel suo "In what way does it become manifest in the fundamental laws of physics that space has three dimensions?". In…Read more

    601 Books on Space
    Maluhy & Co.. 2012.
    Space is one of the most fundamental concepts over which scientific knowledge has been constructed. But it is also true that space concepts extrapolate by far the scientific domain, and permeate many other branches of human knowledge. Those are fascinating aspects that could di per se justify the compilation of a long bibliography. Another one is the passion for books. My interest in some physical, historical and philosophical problems concerning the concept of space in Physics, and its properti…Read more

    On the Physical Problem of Spatial Dimensions: An Alternative Procedure to Stability Arguments
    with Roberto Moreira Xavier
    Fundamenta Scientiae 8 (1): 73-91. 1987.
    Why is space 3-dimensional? The first answer to this question, entirely based on Physics, was given by Ehrenfest, in 1917, who showed that the stability requirement for n-dimensional two-body planetary system very strongly constrains space dimensionality, favouring 3-d. This kind of approach will be generically called "stability postulate" throughout this paper and was shown by Tangherlini, in 1963, to be still valid in the framework of general relativity as well as for quantum mechanical hydrog…Read more

    Causa Efficiens versus Causa Formalis: origens da discussão moderna sobre a dimensionalidade do espaço
    with Roberto Moreira Xavier
    Cadernos de História E Filosofia da Ciência (UNICAMP) 4 (2): 43-64. 1994.
    Metascientific criteria used for explaining or constraining physical space dimensionality and their historical relationship to prevailing causal systems are discussed. The important contributions by Aristotle, Kant and Ehrenfest to the dimensionality of space problem are considered and shown to be grounded on different causal explanations: causa materialis for Aristotle, causa efficiens for young Kant and an ingenious combination of causa efficiens and causa formalis for Ehrenfest. The prominent…Read more

    Em defesa da licenciatura
    Scientia 6 (1): 93-98. 1995.
    A solução do problema educacional brasileiro passa, necessariamente, por duas etapas, que se resumem essencialmente na busca da revalorização do Saber. Independente de qualquer política ministerial, este é o compromisso maior que deveria brotar espontaneamente de toda a comunidade acadêmico-científica. As duas etapas a que nos referimos pouco dependem de verbas e são: a conscientização da responsabilidade e do papel de liderança que cabe a esta comunidade na busca desta solução; a sua capacidade…Read more

    Life and Space Dimensionality: A Brief Review of Old and New Entangled Arguments
    Journal of Astrobiology and Outreach 4 (2): 152. 2016.
    A general sketch on how the problem of space dimensionality depends on anthropic arguments is presented. Several examples of how life has been used to constraint space dimensionality (and vice-versa) are reviewed. In particular, the influences of three-dimensionality in the solar system stability and the origin of life on Earth are discussed. New constraints on space dimensionality and on its invariance in very large spatial and temporal scales are also stressed.
