The Case for Hedonic Primacy: A Framework for Consciousness, Adaptation, and the Engineering of Experience

This paper sets out a philosophical framework I have arrived at through a combination of first-person experience with altered hedonic states, engagement with the neuroscience of reward and adaptation, and extended dialogue with the existing literature on ethics and personal identity. The framework rests on a single foundational claim: positive valence is the only thing that is intrinsically good, and negative valence is the only thing that is intrinsically bad. Every secondary value that humans pursue — meaning, purpose, dignity, accomplishment, freedom, authenticity, even love — derives its value from the hedonic experiences it produces, and nothing else. I argue that the apparent disagreement with this claim in both common intuition and academic philosophy is not evidence against it, but rather an artifact of two related problems: biological hedonic adaptation, which prevents sustained positive experience and therefore conditions us to treat wellbeing as a scarce luxury rather than the point of existence, and the phenomenological asymmetry between peak hedonic states and sober reflection, which means that the sober mind cannot fully access the evidence on which hedonic primacy rests. From the foundational claim I derive a consciousness-centric rather than species-centric ethics, an intensity-threshold account of suffering, a two-level structure distinguishing endpoint ideals from transitional rules, and an account of personal identity grounded in open individualism and gradual substrate replacement that permits cosmic-scale hedonic engineering without requiring death of the self. I close by stating the precautionary conditions under which that engineering would be permissible, and the conditions under which it would not. The framework is presented as revisable in principle. Its core, however, I hold to be as close to self-evidently true as any ethical claim has ever been, for reasons the paper tries to make visible to the reader who has not yet felt them.
