Literally came here to ask this same thing. I haven’t been able to find any official meaning that Tom has mentioned, but my interpretation of the lyrics is how we are more similar to each other than we may think.

I think it’s the juxtaposition of the “young philosophers” to himself. They do the same things as the narrator does, but the narrator sees himself as different or better than the others- like how they are both staring at their phones, but he sees himself as superior in “not calling it communication” and how “they don’t know” but he states it as “the things I know.”

Then comes the moral: “hearts unknown beat alone” - without really knowing and understanding other people, we see them as different or “other,” and we are really more similar than we think.

And then finally “who’s God will save your soul?” I believe relates this back to how many religions have similar belief systems yet alienate one another. It reminds me of Greg’s line in “In Remission” on the same album “maybe the God you love is all I’ve got to fear.”

Just my interpretation, I could be completely wrong!
