The hypothesis in this paper is to defend the idea that the dichotomy between facts and theories, conceptual framework or paradigm uninterpreted experience and world, is a profound error (Davidson), born of an essentially incoherent image of the mind as a spectator passive but critical of an internal libraries (Quine). From a naturalistic account of knowledge, Davidson maintains that requires no appeal to epistemological intermediaries such as facts, data or pure sensory sensations. As a corollary of this thesis supports the search for a foundation of evidence for knowledge is meaningless and is not a suitable position to be even asked.
