Douglas Adams once said there was a theory that if anyone ever understood the Universe, it would disappear and be replaced by something even more incomprehensible. He added that there was another theory that this had already happened. These sorts of things – things such that if you understand them, they get more complicated until you don’t – are called “anti-inductive”.

A couple decades ago — I still say I have mild Asperger’s syndrome — I would have said, “I do not understand small talk. Stop jaw’in and transmit some useful information.” S-l-o-w-l-y, as I learned how to listen, I’ve come around to the view that there are many useful layers of communication. So, new word for 2018 (for me anyway): phatic.
