The Ocean of Consciousness

He acknowledges that human cognitive enhancement has been happening throughout history — literacy, mathematics, glasses, vaccines, and stimulants all enhanced human capacity beyond evolved baseline. The new generation of enhancement is just a continuation of that trajectory. But he raises a structural worry. Most of the enhanced capacities that techno-humanism promises are capacities that strengthen the "intelligence" side of the intelligence-consciousness pairing. They make humans better at the kind of cognition machines are already getting good at, which means even enhanced humans may not be able to keep ahead of unenhanced machines on those dimensions.

The chapter introduces the alternative — the cultivation of consciousness rather than intelligence. Harari notes that human cultures have produced detailed maps of conscious experience for millennia: Buddhist phenomenology, Christian mystical theology, Hindu yoga traditions, Sufi practice, indigenous shamanic frameworks. These maps describe states of consciousness — depths of attention, varieties of compassion, qualities of suffering, modes of insight — that have never been systematically explored by modern science because modern science largely treats consciousness as a black box that produces behavioral outputs.

The chapter's argument is that the "ocean of consciousness" — the full range of conscious states a human can in principle experience — is largely uncharted by the modern scientific apparatus, and that this is humanity's most distinctive territory if intelligence is leaving for the machines. Mapping that ocean might be the project for which humans remain irreplaceable. But the chapter acknowledges this is a thin reed. The economic and political logic of decoupled-intelligence-without-consciousness does not require humans to map any oceans. Techno-humanism may turn out to be a half-step on a trajectory whose end-point is not enhanced humans at all but something post-human, in which case the ocean-of-consciousness project would be a beautiful artifact of a transitional species. Harari leaves the question open and turns in the final chapter to the worldview that follows when humanism finally lets go.
