Abstract
Being-in-the-world defines in Heidegger an ontological and practical existential situation that in a first approach characterizes intellectual knowledge, an approach related to the Husserlian notion of intentionality. In his Curso de teoría del co- nocimiento, Polo rectifies this characterization, stressing the primacy of theory regarding action, and interpreting the practical (technical) relation- ship with the world as a lower level of “having”. Ma- king some comparisons between Husserl, Scheler and Jonas, in connection with Polo’s thought, the article presents different accounts of the notion of the world (phenomenological, metaphysical, mo- ral) that allow to clarify the problem of the rela- tionship between contemplation and action in the world.
