Right. I'm ignorant of Weismann's doctrine. But it does seem to imply purely bottom-up causation. We *could*, I suppose talk of hierarchical systems where the causal flow only went upward ... maybe a bit like the causal cone defined by the speed of light in space-time. Everything within the cone is "same layer causation" and cross-cone relations might be the only time you'd need large-scale, collective effects. [⛧]

The only way I can see to get any kind of downward causation in that case is through iteration, as I mentioned with the sticks (1st stick is completely free, 2nd stick is more constrained, ...). But you can remove time and replace it with some other requirement, like no/minimal space between tiles for sphere packing or, say, aperiodic tilings. In that case, it's not  only the tile shapes, but also *how many* of each shape you have that impinges on their (micro) placement.
