In a relational universe, the only properties of a system that have meaning are those that arise from correlations with other systems. No state exists in an absolute sense independently of other states. Our basic premise is that the universe is built from elementary combinatorial (or relational) structures. These structures change and if we are not to suppose the existence of laws over and above the universe, then they must encode the rules for their own change. Geometry, time and consciousness, (...) it is argued, emerge from such a universe as relational Kantian phenomena. (shrink)
