Probably due to the stress on the brain caused by trying to solve Zeno’s paradox in which doorways play a significant role.
According to the 5th century BC Greek philosopher, it is not possible to cross a threshold because, starting on one side of the threshold, you must traverse a fixed distance. If you traverse that distance at some point you must reach a halfway point. The problem is, with every distance crossed, every remaining span can be divided in half. Infinitely. Thus you are always crossing only part way. Zeno’s also suggested that his paradox might be more easily understood as a argument against the possibility of motion at all.
Anyway, after subconsciously noodling through all of that, the brain is exhausted and can be forgiven for not remembering... uh... well, now I forgot the point of this post.
The greatest argument against the possibility of motion at all is trying to get my teenage son out of bed on the weekend.
Zeno was also known by his other name “Old Pee-Pee Toga”. He always stood outside the bathroom trying to figure out if he was half-way there until he wet himself.
I thought Zeno’s paradox was based on the flight of an arrow toward a target...
In any event, I prefer Lucian the skeptic. He decided that life was an illusion and you should always do what you enjoyed most. He spent the rest of his life at the Roman baths. I gather he looked like a prune when he finally passed.
