Categorization

Our teacher had us read an interesting article by an author named George Lakoff on the topic of categorization. I had never previously put much thought into the topic, as categorization is such a simple thing, right? Well, according to this guy, it's more complicated than what most people assume. He is basically saying that categories are abstract concepts, and as he goes along with this line of reasoning, deduces that if we accept this as true, many of the commonly held western views on reality simply aren't true. To be honest, the topic became more and more dense as I was reading, so by the end he was a bit difficult to follow, but I'm fairly sure the gist of what he was saying is that we need to reconsider some of our basic long-held assumptions about the human mind.
