La tesis del holismo de la confirmación aparece por primera vez presentada de manera explícita y extensa en los escritos de Duhem. Años después, es defendida por Quine, pero no en base a la discusión de teorías científicas particulares, sino en relación con su posición semántica. Desde entonces las relaciones entre el holismo semántico y el holismo de la contrastación han sido discutidas, aunque generalmente de un modo algo despegado del análisis de teorías específicas y sus relaciones. Pretendo mostrar a (...) partir del análisis de un caso, el de las relaciones entre la genética de poblaciones y la teoría de la selección natural, un sentido en el que el holismo de la confirmación puede ser derivado del holismo semántico. The thesis of the confirmation holism appears for the first time explicitly and extensively in the writings of Duhem. Years later, it is defended by Quine, but not based on the discussion of particular scientific theories, but in relation to its semantic position. Since then, the relations between semantic holism and confirmation holism have been discussed, although generally somewhat detached from the analysis of specific theories and their relations. I intend to show from the analysis of a case, that of the relations between population genetics and the theory of natural selection, a sense in which the holism of confirmation can be derived from semantic holism.

I argue that Quinean naturalists’ holism-based arguments against analyticity and apriority are more difficult to resist than is generally supposed, for two reasons. First, although opponents of naturalism sometimes dismiss these arguments on the grounds that the holistic premises on which they depend are unacceptably radical, it turns out that the sort of holism required by these arguments is actually quite minimal. And second, although it’s true, as Grice and Strawson pointed out long ago, that these arguments can succeed only (...) if there isn’t any principled criterion for meaning change, such a criterion turns out to be hard to come by. David Chalmers has recently argued that such a criterion must exist, since the norms governing belief revision are subject to obvious exceptions that can be explained only by appeal to meaning change. But this, I argue, is incorrect: if choices about how to use language are themselves rationally assessable, then there are no such exceptions to be explained. To show that this is so, I formulate a new kind of coherence norm that may be useful for reasoning formally about the relationship between meaning and evidence. (shrink)

With resources hinted at in different ways by both Duhem and Quine, it is argued that some of their misgivings about empirical confirmation, or crucial experiments, may be exaggerated or unfounded; and that such experiments, suitably conceived, can give good meaning to empirical sentences. With appropriate meanings one can then wonder about synonymy and analyticity.

Este artigo mostra que não há uma tese de subdeterminação de teorias científicas pelos indícios observacionais, mas várias. Identificamos quatro, com significados, plausibilidades e implicações distintos. Mostra-se que as mais fortes não passam de conjeturas, e que as mais fracas são mais plausíveis, mas não possuem implicações filosóficas robustas – em particular, não implicam o antirrealismo científico –, embora forneçam indícios de alternativas teóricas sistematicamente ignoradas na ciência, bem como do emprego de critérios em parte valorativos de escolha de teorias.

This multifaceted essay emerges from a host of sources within diverse academic settings. Its central thesis is guided by physicist John A. Wheeler's thoughts on the quantum enigma. Wheeler concludes, following Niels Bohr, that we are co-participants within the universal self-organizing process. This notion merges with concepts from Peirce's process philosophy, Eastern thought, issues of topology, and border theory in cultural studies and social science, while surrounding itself with such key terms as complementarity, interdependence, interrelatedness, vagueness, generality, incompleteness, inconsistency, and (...) mestizaje. Ultimately, a sense of semiosic process pervades in light of combined homogenous and hetergenous tendencies. (shrink)

Contemporary sociology of scientific knowledge (SSK) is defined by its relativist trend. Its programme often calls for the support of philosophers, such as Duhem, Quine, and Wittgenstein. A critical re-reading of key texts shows that the main principles of relativism are only derivable with difficulty. The thesis of the underdetermination of theory doesn't forbid that Duhem, in many places, validates a correspondence-consistency theory of truth. He never said that social beliefs and interests fill the lack of underdetermination. Quine's idea of (...) a selective revision of hypotheses, as well as the neat incompatibility between holism and conventionalism, openly challenges the principles of relativism. Wittgenstein's work, which is not presented in book-form but rather as a tree, forces us to avoid aphoristic choices that credit any text-excising. This remark allows us to tackle the passages that sociological relativism is based on.Mathematical conventions are not anthropological objects. When Wittgenstein examines the "language-games," he only speaks of the functioning of natural language, not to be confused with scientific formal languages. We then should render the formula "language-game" by "well-defined, explicit and compulsory rules of communication", which is a much less attractive formula for relativism. Consequently, there does not exist a real continuity between the epistemologies of Duhem, Quine and Wittgenstein, and the recent works of the SSK. (shrink)
