But when the guiding question (What is the being?) and the grounding question (What is Being?) are asked, we are asking: What is . . . ? The opening up of beings as a whole and of Being is the target for thought. Beings are to be brought into the open region of Being itself, and Being is to be conducted into the open region of its essence. The openness of beings we call unconcealment-alētheia, truth. The guiding and the grounding questions of philosophy ask what beings and Being in truth are. With the question of the essence of Being we are inquiring in such a way that nothing remains outside the question, not even nothingness. Therefore the question of what Being in truth is must at the same time ask what the truth in which Being is to be illumined itself is. Truth stands with Being in the realm of the grounding question , not because the possibility of truth is cast in doubt epistemologically, but because it already belongs to the essence of the grounding question in a distinctive sense, as its "space." In the grounding and guiding questions concerning Being and beings, we are also asking simultaneously and inherently about the essence of truth. "Also" about truth, we say, speaking altogether extrinsically. For truth cannot be what "also" comes forward somewhere in proximity to Being. Rather, the questions will arise as to how both are united in essence and yet are foreign to one another, and "where," in what domain, they somehow come together, and what that domain itself "is." Those are indeed questions that inquire beyond Nietzsche. But they alone provide the guarantee that we will bring his thought out into the open and make it fruitful, and also that we will come to experience and know the essential borders between us, recognizing what is different in him.
But if will to power determines beings as such, which is to say, in their truth, then the question concerning truth, i.e. , the question of the essence of truth, must always be inserted into the interpretation of beings as will to power. And if for Nietzsche art attains an exceptional position within the task of a general interpretation of all occurrence, which is understood as will to power, then the question of truth must play a leading role precisely here.
