Ontologically Appropriate

In the middle of the page, yer 84 on ours 58 an the original translation. Nowadays, there much talk about man's having an environment, umwelt. But this says nothing ontologically, as long as this having is left indefinite in its very possibility. This having is founded upon the existential state of being in because desin is essentially an entity with being in it. It can explicitly discover those entities which it encounters and avail itself of them. It can have the world. If not, youo, scientifically prejudicial. I think that's what he's saying. Can we move forward in the text a little bit?
