There are a number of common-phrases I'll hear like "everything is connected" or "everything is alive/sentient."
However, not everything is connected, effective thinking is very much about identifying independent problems. Also I certainly don't believe everything is alive, and I certainly don't think this opinion should be held on the basis of chemicals rather than scientific data.

Edit: And what's most disconcerting is that they seem to think these phrases "mean" something. If they said "Well, there's really no way I can articulate it, but it's changed my emotional outlook on a lot of things" then I'd be much more receptive.
