La thèse de l'indétermination de la traduction de W. V. O. Quine est certainement une des thèses les plus controversées de la philosophie du langage. Le présent article explique en quoi consiste cette thèse et examine les liens qu'elle entretient avec la thèse de la sous-détermination des théories scientifiques. La première section montre comment la thèse de l'indétermination de la traduction découle de la conception behavioriste du langage de Quine. Les sections suivantes exposent deux façons de dériver la thèse de (...) l'indétermination: par le holisme et le vérificationnisme dans la section 2 et par la thèse de la sous-détermination dans la section 3. La section 4 précise la formulation de la thèse de la sous-détermination proposée dans «On Empirically Equivalent Systems of the World» et la section 5 expose les critiques exprimées par W. Bechtel à propos de cette formulation. Ces critiques témoignent d'une mauvaise compréhension de la position de Quine et j'essaierai de montrer en quoi elles sont fautives. La section 6 traite des deux façons de dériver la thèse de l'indétermination, à la lumière des modifications apportées à la formulation de la thèse de la sous-détermination. Enfin, la section 7 s'intéresse aux questions de fait relatives à la sous-détermination des théories et à l'indétermination de la traduction. (shrink)

Quine’s thesis of underdetermination is significantly weaker than it has been taken to be in the recent literature, for the following reasons: (i) it does not hold for all theories, but only for some global theories, (ii) it does not require the existence of empirically equivalent yet logically incompatible theories, (iii) it does not rule out the possibility that all perceived rivalry between empirically equivalent theories might be merely apparent and eliminable through translation, (iv) it is not a fundamental thesis (...) within Quine’s philosophy, and (v) it does not carry with it the anti-realistic consequences often associated with the thesis in recent debates. The paper analyzes Quine’s views on the matter and the changes they underwent over the years. A conjecture is put forth about why Quine’s thesis has been so widely misrepresented: Quine’s writings up to 1975 tackled primarily the formulation and justification of the thesis, but afterwards were concerned mostly with the question whether empirically equivalent rivals to the theory we hold are to be considered true also. When this latter discussion is read without bearing in mind Quine’s earlier formulation and justification of the thesis, his thesis seems to have stronger epistemic consequences than it actually does. A careful reading of his later writings shows, however, that the formulation of the thesis remained unchanged after 1975, and that his mature and considered views supported only a very mitigated version of the thesis.

Theodore Sider has argued that while there are some philosophical debates about which there is no fact of the matter, debates in normative ethics are likely not among them. This essay investigates a possible counterexample: the debate about so-called dirty hands. The essay first surveys several cases where No-Fact-of-the-Matter (NFM) claims have been made. Taking its cue from these cases, it then outlines two strategies that factualists about some domain can take, as well as two non-factualist counter strategies. Next, it (...) shows how an NFM claim can be defended for the debate about dirty hands. Finally, it argues that this NFM claim is at least as, if not more, plausible for normative ethics as it is for the other instances where NFM claims have been made. (shrink)

The thesis of the empirical underdetermination of theories (U-thesis) maintains that there are incompatible theories which are empirically equivalent. Whether this is an interesting thesis depends on how the term incompatible is understood. In this paper a structural explication is proposed. More precisely, the U-thesis is studied in the framework of the model theoretic or emantic approach according to which theories are not to be taken as linguistic entities, but rather as families of mathematical structures. Theories of similarity structures are (...) studied as a paradigmatic case. The structural approach further reveals that the U-thesis is related to problems of uniqueness in the representational theory of measurement, questions of geometric conventionalism, and problems of structural underdetermination in mathematics.

Underdetermination of theory choice claims that empirical evidence fails to provide sufficient grounds for choosing a theory over its rivals. We explore the epistemological and methodological significance of this thesis by utilising a classificatory scheme to situate three arguments that purport to establish its plausibility. Proponents of these three arguments, W.V.O Quine, John Earman, and Kyle Stanford, use different premises to arrive at the conclusion that theory choice is empirically underdetermined and their classification along the proposed schema brings out the (...) variety in underdetermination arguments and the historical trajectory of the thesis. Although the epistemological significance of underdetermination—it is seen as undermining the doctrine of scientific realism—is widely discussed in the literature, Quine understood the acceptance of the thesis as interrogating the attitude one is justified in adopting towards rival theories. We argue that sticking with one’s own theory in the face of underdetermination leads to a distinct type of disagreement, which we present as the methodological significance of underdetermination. The examination of the methodological significance of underdetermination allows us to propose weak underdetermination as a philosophically interesting variant of underdetermination. (shrink)
