Separation as Projection
Let's assume, as a working hypothesis, that separation is not the ground of reality.
That the division between inner and outer, between one mind and another, between subject and world, is not ontologically basic but derived — an effect of perspective, a contour, a projection. That the ground is continuous.
What follows immediately?
The first consequence is that the appearance of separation now needs to be explained, rather than simply taken as the starting point. Under standard individualism, separation is the given and continuity (when it shows up) is the mystery. Under the unity premise, the relation flips: continuity is the ground, and separation is what has to account for itself.
The most economical image for this is still projection. A single object, lit a certain way, casts distinct shadows on different surfaces. Someone who only sees the shadows faces a plurality of separate shapes that nevertheless move in coordination. The coordination looks inexplicable as long as you stay on the plane of the shadows. It becomes trivial once you recognize the single object casting them.
Projection here in the optical sense — not the sense psychoanalysis made famous.
David Bohm put it with the metaphor of the fish tank and the two cameras: the same fish, filmed from different angles, appears on two screens as two fish moving in mysterious synchrony. The mystery only exists for someone who ignores the tank. For Bohm, the image was no ornament: it was the core of his proposal that the visible world unfolds from a ground where separation does not yet exist.
On this reading, each "I" is not an independent fragment of reality. It is the whole of the real, projected through a particular filter — a pattern of selection, of limitation, of organization. The filter does not create reality; it determines the contour under which reality appears as this perspective, with these limits, with this apparent privacy. Where the filter comes from — history, inheritance, constitution, or something we don't know how to name — stays open. What matters is the function.
This does not make individual experience illusory in the sense of false. The shadow is real as a shadow. A toothache is real as a toothache. What dissolves is not the reality of local experience, but the pretension that local experience exhausts or grounds reality. And recognizing the ground takes nothing away from the contour. The perspective is not made smaller by not being the whole — it is the whole, appearing under one form.
The radical privacy of consciousness — the fact that "only I" have this pain, this thought, this visual field — stops being proof of separate mental substances. It becomes the way continuity particularizes when accessed through a stable filter. Privacy is an effect of perspective, not an ontological barrier.
Two consequences follow at once.
First: correspondences without apparent causal transmission (what we usually call synchronicity, contagion, complementarity, or simply "meaningful coincidence") stop being anomalies that require special bridging mechanisms. They become the expected behavior of a continuous system projected into multiple contours. What needs explaining becomes the appearance of isolation, not the occasional occurrence of coordination.
Second: the suffering tied to exclusive identification with the contour — the feeling of being a closed unit facing an external world that is threatening or indifferent — acquires a new status. It does not disappear. But it stops being the final ontological condition and becomes the tension between limited identification and the continuous ground of which that identification is an expression.
None of this proves the premise. It only shows what the premise reorganizes right away: separation stops being the ground and becomes the problem; continuity stops being the miracle and becomes the ground; and a set of phenomena that individualism treats as residual or exceptional move to the center of the architecture.
