Here is the claim that makes this entire book possible, and it must be stated with full precision because it is not obvious, not generally acknowledged, and not negotiable as a foundation for everything above it.
Abundance is a perceptual condition — a quality in which the environment registers as containing more than enough, in which possibility registers as real, in which the future registers as approachable. Scarcity, similarly, is not fundamentally an economic fact. It is a perceptual state — the state of a nervous system that perceives threat from every horizon, that cannot register sufficiency, that chronically computes from the assumption of not-enough.
The behavioral economists documented the symptom
Sendhil Mullainathan and Eldar Shafir's Scarcity demonstrates that the cognitive load of felt scarcity — regardless of actual resource availability — produces tunnel vision, reduced executive function, increased impulsivity, and degraded long-horizon decision-making. Their finding: the poor make worse financial decisions not because of fixed cognitive deficits, but because the experience of financial scarcity consumes cognitive bandwidth, leaving less available for deliberate reasoning.
This is the floor-deficiency signature, described in economic terms. What they do not address — because it is outside their disciplinary frame — is the neurological substrate of the scarcity-perception itself. The tunnel vision is the signature of low cholinergic tone: attention contracts to the threatening signal, to the near horizon, to the not-enough. The executive function degradation is the signature of prefrontal-cholinergic decoupling under stress. The impulsivity is hyperbolic discounting from a nervous system that cannot access the future because it cannot get out of the crouch of the present.

What the floor lets you see, that the crouch keeps you from seeing.
What the grounded floor produces, instead
The grounded floor — adequate cholinergic tone, maintained by the practices in Essay III, resting on adequate substrate — does not produce these effects. The broadened perceptual field includes the far horizon. It includes possibility. It includes the capacity to perceive what is present, rather than only what is missing.
It makes the full picture available. And the full picture, in most human situations, contains more abundance than the depleted floor can detect.
This is the hinge of the spine. The individual on a grounded floor is not the same economic agent as the individual on a depleted floor. They are making decisions from different perceptual fields, with different cognitive bandwidths, from different relationships to the future. The economics that emerges from a population of grounded individuals is not an incremental improvement on behavioral economics. It is a different discipline, built on a different subject.

The same world. A different receiver. The economics that follows is a different discipline.
