“Metaphysics thinks about beings as beings. Wherever the question is asked what beings are, beings as such are in sight. Metaphysical representation owes this sight to the light of Being. The light itself, i.e., that which such thinking experiences as light, does not come within the range of metaphysical thinking; for metaphysics always represents beings only as beings. Within this perspective, metaphysical thinking does, of course, inquire into the being which is the source and originator of this light. But the light itself is considered sufficiently illuminated as soon as we recognize that we look through it whenever we look at beings.In whatever manner beings are interpreted―whether as spirit, after the fashion of spiritualism; or as becoming and life, or idea, will, substance, subject, or *energeia*; or as the eternal recurrence of the same events―every time, beings as beings appear in the light of Being. Wherever metaphysics represents beings, Being has entered into the light. Being has arrived in a state of unconcealedness (aletheia). But whether and how Being itself involves such unconcealedness, whether and how it manifests itself in, and as, metaphysics, remains obscure. Being in its revelatory essence, i.e., in its truth, is not recalled. Nevertheless, when metaphysics gives answers to its question concerning beings as such, metaphysics speaks out of the unnoticed revealedness of Being. The truth of Being may thus be called the ground in which metaphysics, as the root of the tree of philosophy, is kept and from which it is nourished.Because metaphysics inquires about beings as beings, it remains concerned with beings and does not devote itself to Being as Being. As the root of the tree, it sends all nourishment and all strength into the trunk and its branches. The root branches out in the soil to enable the tree to grow out of the ground and thus to leave it. The tree of philosophy grows out of the soil in which metaphysics is rooted. The ground is the element in which the root of the tree lives, but the growth of the tree is never able to absorb this soil in such a way that it disappears in the tree as part of the tree. Instead, the roots, down to the subtlest tendrils, lose themselves in the soil. The ground is ground for the roots, and in the ground the roots forget themselves for the sake of the tree...Metaphysics, insofar as it always represents only beings as beings, does not recall Being itself. Philosophy does not concentrate on its ground. It always leaves its ground―leaves it by means of metaphysics. And yet, it never escapes its ground...Insofar as a thinker sets out to experience the ground of metaphysics, insofar as the attempts to recall the truth of Being itself instead of merely representing beings as beings, his thinking has in a sense left metaphysics. From the point of view of metaphysics, such thinking goes back into the ground of metaphysics."―from_The Way Back to the Ground of Metaphysics_”
