Something For Our Poets To Remember?

Etherealizing

A theory if you hold it hard enough
And long enough gets rated as a creed:
Such as that flesh is something we can slough
So that the mind can be entirely freed.
Then when arms and legs have atrophied,
And brain is all that's left of mortal stuff,
We can lie on the beach with the seaweed
And take our daily tide baths smooth and rough.
There once we lay as blobs of jellyfish
At evolution's opposite extreme.
But now as blobs of brain we'll lie and dream,
With only one vestigial creature wish:
Oh, may the tide be soon enough at high
To keep our abstract verse from being dry.

--- Robert Frost, from Steeple Bush (1947)
