The poem is from someone whose online pseudonym is atiguhya padma. I'll quote the first verse, the refrain, and the beginning of the second verse to give you enough flavor to decide if you want to follow the link. There are about 9 verses total.
Someone looked out of their window
And said to me: the world looks
So beautiful, that I praise God
Each day for this wonderful life,
This landscape of happy creatures
And rolling fields of growth and form.
He obviously had not read Tennyson
And he wasn’t an ecologist,
For he had no firm idea of how
Ecosystems sustain themselves.
There are no beautiful surfaces
Without a terrible depth.
You said you loved me.
And I wondered what that could mean...
Reductionist thinking can connect emotions triggered by the surfaces encountered in daily life to a larger set of concepts and predictions, and this seems to have consequences for both the thinking and the emotions that isn't often discussed and is even less often discussed well. I liked the poem because it addressed the issues pretty well and in an emotional mode, which is doubly rare.
The "no beautiful surfaces" refrain is a quote from Nietzsche which has little easily accessed online scholarship. Nothing in the first few pages of google results mentions a source for the quote so I was suspicious at first that it was even a quote by him, but references available via google books indicate that it comes from one of his notebooks. I haven't tracked down the notebook (it doesn't seem to be in gutenberg), so I'm not sure if the original source carries the specific connotations the poem attributes to the phrase, or if it is just a cool line put to good use in a new context.
