It is a very interesting question. As an FP fan, I'd argue that we model the world primarily in terms of the actions we want to perform, with the objects secondary. But I'm obviously biases. Furthermore, perhaps how we actually model the world mentally is or should not bear much of a relation to how we do so in code. I haven't made my mind up about these things, even though I lean towards the FP approach in my day to day coding. But I love (constructive) discussions about the issue because somehow I feel they're about more than just 'making shit work'. Aside from the occasional flame-war I really like the discussions on HN about this stuff, and usually there are at least a few comments that give me new insight into both OOP and FP.
