If Hemn space is the landscape, and one cosmos is a single geometric point in it, then a given consciousness is a spot of light moving, like a searchlight beam, over that landscape--brightly illuminating a set of points--of cosmi--that are close together, with a penumbra that rapidly feathers away to darkness at the edges. In the bright center of the beam, crosstalk occurs among many variants of the brain. Fewer contributions come in from the half-lit periphery, and none from the shadows beyond.
