Extended Consciousness
Chalmers's extension of the extended mind thesis to phenomenal experience — the contested proposal that some conscious states extend beyond the skull into coupled cognitive systems.
Extended consciousness is the thesis that conscious experience, like cognition more broadly, may extend beyond the biological organism into tools, environments, and — in the AI age — cognitive collaborators. Chalmers, with Andy Clark, defended the extended mind thesis in 1998. Extending the thesis to consciousness is more radical and more contested. If accepted, it reframes human-AI collaboration as potentially constitutive of a single extended conscious system; if rejected, it preserves consciousness as belonging exclusively to the biological participant. The question has practical stakes for how we understand what the AI partnership produces.

The extended mind thesis holds that cognitive processes can extend beyond the skull when external resources are coupled tightly enough with biological processes. The canonical example is Otto's notebook: if Otto reliably consults the notebook in the way others consult biological memory, the notebook functions as part of his cognitive system. The extension of this logic to consciousness is controversial. Clark has been cautious; Chalmers has
