"What is the reason for a unity/oneness? For however many things have a plurality of parts and are not merely a complete aggregate but instead some kind of a whole beyond its parts, there is some cause of it since even in bodies, for some the fact that the there is contact is the cause of a unity/oneness while for others there is viscosity or some other characteristic of this sort." — Aristotle, Metaphysics.
