McCarthy & Rilke

While reading Cormac McCarthy's play The Stonemason yesterday, I noted this allusion to Rilke's Duino Elegies:

"BEN: The big elm tree died. The old dog died. Things that you can touch go away forever. I dont know what that means. I dont know what it means that things exist and then exist no more. Trees. Dogs. People. Will that namelessness into which we vanish then taste of us?"

Here's Rilke's Second Duino Elegy:

"Like dew from the early grass, that which is ours rises from us
...like the heat from a hot dish. O smile, where do you go? O expression in the eyes:
new warm escaping wave of the heart--;
how it hurts me; we are these very things. So does the world-space,
in which we come loose, taste of us?"
