Here I go! said Blurtso, looking down at what lay below him. Here I go! he said again, still looking at all the things that lay below. Blurtso’s boney little hooves clung tightly to the rocky spine on which he stood, and his pin-point eyes were bright and full of frenzy. Here I go! he said a little more quietly, and with much less conviction. Here I go! Here I go! Here I go! he repeated, and clung even more tightly to the spine that began to cut into his hooves and make them bleed. Here I go! he said more loudly, but with no conviction at all. Here… I… and off he went, slipping, sliding, and tumbling into the only future that awaited him.
Heraclitus, said the professor, was a Greek who wrote, “You can’t step into the same river twice…” Why would anyone step into a river? said Blurtso, that’s what bridges are for. You can’t step into the same river, continued the professor, because the river is always changing, and when you step in a second time, it’s a different river, and you are changing too, and are not the same as when you first stepped in. In fact, repetition is a myth, it’s impossible… I’m sorry, said Blurtso, I’m afraid I wasn’t listening, could you repeat that?
