27 As for the "problem of science", Roberto Machado evaluates that since "[Nietzsche], denies to science the possibility of elucidating its own problem by itself, denies to an internal criticism of knowledge the possibility of constituting itself as true criticism, the essential part of the d?rche consists in connecting science with an exterior capable of revealing the real dimensions and purposes of the scientific project; it consists in explaining the moral foundations of science, indicating, at the same time, art as an alternative model for rationality. Hence the privilege of art and moral as instances that make the nietzschean discourse on science possible, indicating its two main directions". (Cf. Nietzsche e a Verdade. 2ª. ed. Rio de Janeiro: Graal, 2002, p. 8).
