In a sense, it does find more fundamental ones, but I don’t think this is a good way of thinking about it. I’ve suggested elsewhere that what typically gets labeled “non-reductionism” is really basically a form of “greedy reductionism”—essences add, in some sort of pretty much linear fashion. But real things aren’t typically just collections of fundamental things, with their properties summed up; they’re patterns in the interactions of these things (not just collections of particles!), and understanding their properties requires understanding these interactions.
