# Irreducible Multiplicity The conviction that all phenomena in existence are fundamental multiplicities that thereby cannot be reduced to any single, delimited objects, as when Friedrich Nietzsche claims that nothing in the world can be reduced to less than the number two. Within a syntheist ontology, the irreducible multiplicity is unavoidable since ontology always must begin with a drastic information write-off in connection with the transition from mobilism to eternalism.
