"What is metaphysics?" The question awakens expectations of a discussion about metaphysics. This we will forgo. Instead we will take up a particular metaphysical question. In this way it seems we will let ourselves be transposed directly into metaphysics. Only in this way will we provide metaphysics the proper occasion to introduce itself.
Our plan begins with the unfolding of a metaphysical inquiry, then tries to elaborate the question, and concludes by answering it.
From the point of view of sound common sense, philosophy is in Hegel's words "the inverted world." Hence the peculiar nature of our undertaking requires a preliminary sketch. The sketch will develop out of a twofold character of metaphysical interrogation.
First, every metaphysical question always encompasses the whole range of metaphysical problems. Each question is itself always the whole. Therefore, second, every metaphysical question can be asked only in such a way that the questioner as such is also there within the question, that is, is placed in question. From this we conclude that metaphysical inquiry must be posed as a whole and from the essential position of the existence [Dasein] that questions. We are questioning, here and now, for ourselves. Our existence - in the community of researchers, teachers, and students - is determined by science. What is happening to us, essentially, in the grounds of our existence, when science has become our passion?
 The scientific fields are quite diverse. The ways they treat their objects of inquiry differ fundamentally. Today only the technical organization of universities and faculties consolidates this multiplicity of dispersed
