Lyric discussion by ScythianEmpress 

Here's a quote from Sufjan about Impossible Soul from an interview with Drowned in Sound:

"It’s like a Woody Allen film, you know, where there’s the slapstick on the surface that everyone can appreciate, but then, deeper, there’s all these original details. Maybe at the heart of a good Woody Allen film there’s some kind of universal tragedy of humanity that he’s speaking about; a much bigger thing. ‘Impossible Soul’ is really about a very primitive object. I want to get with a girl, and there’s all these obstacles, and shortcomings, and miscommunication… and this is a basic fundamental of life, between two human beings.

But then very quickly — through an expository detour — it becomes something else. It’s all about personal happiness, or the state of mankind, or the cosmos — the cosmos is drawn into it. And then it becomes about… what is at the heart of our inability to really connect? Is it fear, or is it self-consciousness? And then it becomes a kind of therapeutic discourse that becomes the centrepiece of the song. But it’s no longer about, just like, “girl, I want to get with you.” It’s more like… what’s wrong with civilisation (laughs)."

It makes a lot of sense with the lyrics.
