According to the received translational interpretation of incommensurability, incommensurability is viewed as untranslatability due to radical variance of meaning or reference of the terms in two competing scientific languages. The author argues that the translational approach to incommensurability does not effectively clarify the concept of incommensurability. Since it cannot provide us with tenable, integrated concept of incommensurability, it should be rejected.

El año 1962 vio la introducción, por parte de Kuhn y Feyerabend, de la tesis de la inconmensurabilidad de las teorías científicas . Desde entonces, la tesis ha sido debatida ampliamente y ha atraído muchos críticos. Su influencia aún es considerable, particularmente en las áreas de la historia y la filosofía de la ciencia interesadas en el cambio y la elección de teorías. Esta influencia se debe, en gran medida, a la inmensa popularidad de la obra maestra de Kuhn, La (...) Estructura de las revoluciones científicas, la cual asegura que la idea de la inconmensurabilidad continúe alcanzando un público amplio. Sin embargo, no es tan ampliamente apreciado que la versión de Kuhn de la inconmensurabilidad ha ido sufriendo, con el tiempo, un proceso continuo de revisión y clarificación. Como resultado de esto, la versión de la tesis por la que Kuhn es mejor conocido difiere notablemente de la versión que él asume en el presente. En este artículo presento un estudio del proceso de cambio, caracterizando las etapas principales por las que transcurre el concepto kuhniano de inconmensurabilidad. (shrink)

Since 1962 Kuhn's concept of incommensurability has undergone a process of transformation. His current account of incommensurability has little in common with his original account of it. Originally, incommensurability was a relation of methodological, observational and conceptual disparity between paradigms. Later Kuhn restricted the notion to the semantical sphere and assimilated it to the indeterminacy of translation. Recently he has developed an account of it as localized translation failure between subsets of terms employed by theories.

Kuhn's alleged taxonomic interpretation of incommensurability is grounded on an ill defined notion of untranslatability and is hence radically incomplete. To supplement it, I reconstruct Kuhn's taxonomic interpretation on the basis of a logical-semantic theory of taxonomy, a semantic theory of truth-value, and a truth-value conditional theory of cross-language communication. According to the reconstruction, two scientific languages are incommensurable when core sentences of one language, which have truth values when considered within its own context, lack truth values when considered within (...) the context of the other due to the unmatchable taxonomic structures underlying them. So constructed, Kuhn's mature interpretation of incommensurability does not depend upon the notion of truth-preserving translatability, but rather depends on the notion of truth-value-status-preserving cross-language communication. The reconstruction makes Kuhn's notion of incommensurability a well grounded, tenable and integrated notion.Author Keywords: Incommensurability; Thomas Kuhn; Taxonomic structures; Lexicons; Truth-value; Untranslatability; Cross-language communication.
