GA49:9 – o que é?

(…) We experience and consider that which “is.” Fine; but what merits the distinctive designation: it “is”? What is called “being”?

This chair over there – “is.” Is that which “is,” in the manner of the chair? With this, do we have a yardstick for measuring what “is”? All sorts of things “are” in such a way; whence the measure of being? Is there a measure here at all? The relation to that which “is,” and even the essential relations: difficult to experience. Wherein lies the ground of the “difficulty”? (the abandonment of beings by being – the forgetting of being by the human)

So, not only, nor first of all, to learn about something or other; not some sort of “instruction” about learned matters. But surely still less a snatching at what is “practically” useful and “germane to life.”
