The idea of spontaneous order is a little bit controversial in economics, but I think it should be a sub branch or something we might call emergence. And the idea of emergence in philosophy is that an emergent property or substance arises out of some more fundamental entities and yet they're novel or irreducible with respect to them. We can look at the underlying parts and think that we do and the mistake is to think we could start with the parts and end up with the result. But understanding that it's not designed makes the appreciation of each individual action within it a lot deeper.
