A Multi-Order Evolutionary Theory of Desire: The Reproduction-First Hierarchy and Its Implications for Human Uniqueness and AI Value Alignment

This paper introduces a Multi-Order Evolutionary Theory of Desire, redefining “desire” not as a psychological state but as a cumulative structural hierarchy through which living systems maintain, replicate, and refine environmental adjustment. Departing from traditional survival-centric models, the framework establishes Reproduction (Order 1) as the primary phylogenetic driver, preceding Autonomous Survival (Order 2). The theory traces the evolution of desire through six distinct orders: • Replication • Autonomous Survival • Emotional Compression • Meta-Emotional Regulation • Value Abstraction • Systematization (Human-specific) Humans are posited as the only extant species capable of the Sixth Order, entailing the conscious objectification, design, and extension of value-emotion systems. Orders 6-2 (System Design/Extension) and 6-3 (System Deconstruction/Self-awareness) are distinguished to guide AI Value Alignment: AI should emulate 6-2 for ethical consistency while avoiding 6-3-induced nihilistic behavior. The theory remains falsifiable through evidence of non-human species exhibiting sixth-order capabilities.
