Bam. I was about to comment that the 'thingness' of things remains because of their structural persistence. A river remains the same river not because the atoms which make it up stay the same but because water flows down the same channel. Even as the channel changes, it still changes from the old channel. Yes, fundamentally it is not the same, but only from an ahistorical perspective. Things exist in time.
Yeah, and even the snapshot of a "river" is wuzzy. Do you include the dirt within? The bacteria? Do you include the water soaked into the sand below? How far? Is the boat defined by the (hopefully minimal) amount of water soaked into its hull? It's all just a human construct and debating the nitty gritty is, in my opinion, pretty pointless.
