The paper consists of two parts. The first critically analyses Meyer’s [2005] version of the triviality objection to presentism (according to which, presentism is either trivial or untenable), and tries to show that his argument is untenable because – contrary to what he claimed – he did not take into account the entire possible spectrum of interpretations of the presentist’s thesis. In the second, positive part of the paper, it is shown that a leading form of tensed theory of time postulates the same ontology as presentism and that it avoids the triviality problem which means that it can be used to generate an alternative formulation of presentism which is no longer vulnerable to the triviality objection.

In the article I subject to criticism Field's argument, according to which field theory takes space-time to be a substance, since it ascribes field properties to space-time points. The fundamental flaw of this argument, I suggest, is the incompatibility of Field's interpretation of field theory with the way this theory is understood and utilized by its users, namely scientists. My criticism is based on the assumption that one cannot propose an ontology of a given scientific theory and at the same time imposing on it an interpretation which clashes with the interpretation current among its users. I also suggest that in order to establish the ontology of a scientific theory one should take into account not only the way it functions but also the way it has been constructed. According to this criterion, field theory does indeed take space-time to be a substance

Resumo Este artigo analisa, as recentes versões, da objecção à existência de um fluxo do tempo, com base na pergunta: “Com que velocidade flui o tempo?”. O autor mostra que as soluções existentes para o problema não são plausíveis e, que em vez disso, a resolução deve ser encontrada numa nova concepção de fluxo temporal, que evite tais dificuldades. A teoria metafísica proposta desenvolve as ideias de Broad e Prior sob um novo enquadramento, que invalida a objecção resultante da questão sobre o ritmo da passagem do tempo e das respostas “segundo a segundo”. Neste texto também se procura mostrar, que esta teoria metafísica, aqui proposta, possui outras virtudes que testemunham a seu favor. Palavras-chave : existência dinâmica, fluxo do tempo, presentismo, velocidade de passagem do tempoThe paper analyzes some recent versions of the objection to the existence of the flow of time based on the question: “How fast does time flow?”. It shows that the replies given to the problem are implausible and instead proposes a solution for the issue in the form of a conception of the flow of time which can avoid such a difficulty. The proposed metaphysical theory develops the ideas of Broad and Prior in a radical way and invalidates the objection resulting from the question about the rate of passage and answers “second per second”. The paper also tries to show that this metaphysical theory has other virtues which testify in favor of it. Keywords : flow of time; rate of time’s passage; presentism; dynamic existence
