Thing #1: “But he did not take into account that the best of men, free from all wickedness, would join together the better to accomplish their goal, just as birds flock together the better to travel in company. Or as beavers congregate by the hundreds to construct great dams, which could not be achieved by a small number of them… That is the foundation of society amongst social animals, and not fear of their kind, which hardly occurs among the beasts.” Gottfried Wilhelm Leibniz, New Essays, III, 1. (He clearly forgot to add the words, “visible from outer space” after the hyperlink.)
Thing #2: Even more exciting than Leibniz’s thoughts about beavers, the first beaver kits (=baby beavers) for a very, very long time indeed have been born in the wild in Britain! Over here; with slideshow pics here.
