1730 Paragraph 19
Panel 1 and 2
If the anomalous is neither an individual nor a species, then what is it? It is a phenomenon, but a phenomenon of bordering. This is our hypothesis: a multiplicity is defined not by the elements that compose it in extension, not by the characteristics that compose it in comprehension, but by the lines and dimensions it encompasses in "intension." If you change dimensions, if you add or subtract one, you change multiplicity. Thus there is a borderline for each multiplicity; it is in no way a center but rather the enveloping line or farthest dimension, as a function of which it is possible to count the others, all those lines or dimensions constitute the pack at a given moment (beyond the borderline, the multiplicity changes nature).
Panel 3
Sometimes each and every animal reaches this line or occupies this dynamic position, as in a swarm of mosquitoes, where "each individual moves randomly unless it sees the rest of [the swarm] in the same half-space; then it hurries to re-enter the group. Thus stability is assured in catastrophe by a barrier."
Panel 4
It is true that bands are also undermined by extremely varied forces that establish in them interior centers of the conjugal, familial, or State type, and that make them pass into an entirely different form of sociability, replacing pack affects with family feelings or State intelligibilities. The center, or internal black holes, assumes the principal role. This is what evolutionism sees as progress, this adventure also befalls bands of humans when they reconstitute group familialism, or even authoritarianism or pack fascism.
