The future, thought Blurtso, doing his best to understand the idea. What could that be? Something that has not happened and is not happening and may not happen but will happen in a present that is not this present. Hmm, a present that is not this present. Where does this present end and the next present begin? If I found that point, would that be the future? Blurtso did not have a very big brain, but even he knew that such a point would never be found. There is only one present, he said with confidence, even I know that.
