The Logos, for a Peircean neoplatonist, is this property of the relationship patterns reviewed in emergent and dynamic behavior patterns. Logos from Nomos, and Nomos from Eros: Reason is built from the Law, and the Law is built on the Ends.
This exercises non-efficient "finious" (basically, final) causation throughout history: the lawlike alignments of all phenomena in phenomenon-space accumulate along emergent pathways.
The Logos writes itself from the absolute totality of those pathways.
