Peirce conceived of methodology, or methodeutic, as he preferred to call it, as one of the three major parts of logic taken broadly--the other two being the theory of signs and formal logic. Unlike these two, however, his theory of methodology remained mostly programmatic, and there is little more than fragmentary suggestions about it scattered through his writings. But by gathering them together and pursuing their insights, it is possible to indicate how he might have divided and developed it: 1) (...) The nature of scientific discourse and how it differs from non-scientific. 2) The logic of inquiry, both heuristic and systematic, according to the modes of argument as deductive, inductive, or abductive (i.e. hypothesis) or a combination or all three. 3) The assurance of science considered in the factors that thwart or promote inquiry.

A teologia de Karl Rahner teve um grande impacto no concílio Vaticano II e no tempo que se Ihe seguiu. Em ordem a compreender-se o seu argumento teológico é importante tomar em conta as suas bases filosóficas, especialmente a sua compreensão do "método transcendental". Neste sentido, opresente artigo começa por prestar atenção à abordagem transcendental de Kant. Em seguida investiga a transformação do método transcendental operada na obra de Joseph Maréchal, o qual fez uso dele em ordem a demonstrar a (...) orientação dinâmica do conhecimento humano e da sua decisão em favor do "Absoluto do Ser". Deste modo, o autor do artigo demonstra até que ponto Maréchal fornece uma fundação para a metafísica, a qual é bem diferente da metafísica do racionalismo que Kant tinha criticado. Inspirado por Heidegger, Rahner deu a esta abordagem transcendental uma viragem fenomenológica, ao mesmo tempo que forneceu uma reinterpretação de termos-chave da metafísica clássica, a qual encara como não dependente de uma cosmologia ultrapassada e que ao mesmo tempo é de grande relevância existencial para a vida humana. O artigo visa demonstrar, deste modo, até que ponto esta reinterpretação influenciou o pensamento teológico de K. Rahner. /// The theology of Karl Rahner had an enormous impact on Vatican II and the time following. In order to understand his theological reasoning it is important to take into account his philosophical foundations, especially his understanding of the "transcendental method". This article pays attention to the transcendental approach of Kant. Then it investigates the transformation of transcendental method in the work of Joseph Maréchal who used it to show the constitutive function of the dynamic orientation of human knowledge and decision towards the "Absolute of Being". He thereby provides a foundation for metaphysics, which is quite different from the metaphysics of rationalism which Kant had criticised. Inspired by Heidegger, Rahner gave this transcendental approach a phenomenological turn. He provided a reinterpretation of key terms of classical metaphysics, which is not dependent on an outmoded cosmology and which is at the same time of existential relevance for human life. This reinterpretation influenced the theological thinking of K. Rahner. (shrink)
