This work proposes a complete philosophical system grounded in a single foundational claim: that Absolute Nothingness is logically incoherent, and that this incoherence is the sufficient and necessary condition for the existence of everything. From this claim, developed into a formal theorem by diagonal proof, the system derives a comprehensive ontology, a cosmology, a philosophy of mind, and a practical ethics. The system is called Processism. Where previous process philosophies presuppose the existence of process and proceed to describe its structure, Proces-sism asks the prior question: why does process exist at all? The answer proposed here does not appeal to divine agency, brute contingency, or empirical observation. It appeals to logic alone. The argument proceeds in five movements: a logical foundation establishing the necessity of process through two diagonal proofs on the impossibility of absolute absence and the incoherence of static distinction; an ontology in which matter, energy, space, and time are configurations of process rather than its substrate; a physical framework in which the necessity of process finds expression as non-zero destructive potential at every point in spacetime, with complexity emerging at the edge of chaos; a philosophy of mind in which consciousness is the amplified expression of a structural property present in all process from its origin; and an existential ethics of construction without anxiety, of meaning without permanence, of freedom grounded not in escape from finitude but in the full acceptance of it. The formal results are developed rigorously in two companion papers Rodríguez Suárez(2026a), Rodríguez Suárez(2026b). This paper presents the system as a whole.
