> it makes me wonder why you picked that phrase It took me a few goes to refine the idea. I started with the word sorrowful and thought "ok what could not possibly be sorrowful?" -> a car parking space. Ok then what attributes could a car parking not have -> being liquid Then once I had got the idea then I wanted some other physical attribute this nonexistant thing might have and that got me to temperature. I agree with your idea that it's quite interesting to think about properties of concepts we are currently unable to communicate at all in our language. For example if my intuition is correct, even if you have two concepts which are completely meaningless you would be able to discern similarity/difference between them conceptually, and this is leading to your centroid idea. If we look at those centroids, some might land in semantically meaningful places ("Who knew? The average of tennis and squash is badminton!") whereas some might end up in this void space and that might be quite fascinating. I've always thought[1] that creativity is essentially about making connections between concepts that had previously been thought to be unconnected and therefore it seems to me that some (not all) of these void spaces have potential to be joined in to the mainstream semantic space over time as people find ways to link these concepts to things we already have some meaning for. That's very interesting to me. [1] After reading "The Act of Creation" by Koestler
