This study discusses the substance-tradition from Aristotle to Kant, Gödel, Quine, Strawson, Armstrong and others, the concept of matter and causation in quantum physics, Being-thinking from Aristotle to Heidegger, and system-building from Plato to Whitehead. It synthesizes the Kantian phenomena-noumena, extends the Quinean ontological commitment, creates a Gödelian foundationalist truth-probabilism, relativizes the Whiteheadian actual entity, extends the Aristotelian-Heideggerian Being to a nomic-nominal, verbal-processual To Be and overhauls perspectival-absolutist, non-foundationalist and relativist concepts of Reality. The resulting scientific ontology is termed Einaic Ontology for maximalist, mutually collusive, categorial reasons. The Appendix explains Heidegger’s anthropologized Being as ontologically and cosmologically defective.
