The 1943 science fiction short story Mimsy Were the Borogoves by Lewis Padgett is about a toddler and his infant sibling who do things that are quite unusual.
It is a story I am reminded of this whenever I see young children playing, unfettered by ‘impossibilities’ that are so obvious to adults. It’s not so much the specific story line as the concept that there is more to our existence than can be described by our senses and the associated four dimensions.
In my writing, I present characters with something that is ‘impossible’ and then ask them to find out how such a thing could occur.
I’m often surprised by what they come up with.
