You might find this interesting: https://en.wikipedia.org/wiki/Binary_opposition https://en.wikipedia.org/wiki/Binary_opposition One way to think about is that given a set of items, you want to understand them by finding both commonality and distinction between them. Partitioning into two sets is the simplest form that accomplishes some of both. If you lump them all into a single set, you may have a sense of commonality, but you've learned nothing about distinguishing them. If you put each element into its own set, you have distinguished all of them, but learned nothing about what they have in common. You could form the elements into pairs, but the it's not clear what to do with the odd one out if there is one. Given multiple items, you can always split them into two sets and how you choose to do that reflects both what the elements in each set have in common, while also showing how the two sets differ. I suspect that binary opposition is in some ways fundamental to cognition. It certainly shows up profoundly throughout all cultures across all history: sun and moon, night and day, yin and yang, god and devil, woman and man, earth and sky, etc.
