In this paper we deal with a not so slight misunderstanding about Heidegger’s conception of science(s). We try to show that instead of a so-called «anti-scientism» we find rather a critical thought on the part of Heidegger. Critical in two senses: one that implies a questioning and an explicitation of the pre-scientific, non-scientific foundations (or conditions) of science and the analysis of the relation between sciences as «regional ontologies» and philosophy as «fundamental ontology»; another that suggests the «need of another (...) thinking», an alternative (certainly discussible) to the predominant calculative thinking of «the era of science».
