Words are maps to the terrain of experience/the universe. But the problem with words is that they define strict categories (you can cope with this by establishing a spectrum and not binary things: "not as reasonable"/"sillier than X") and those who rely only on words and not their own eyes and reasoning will be confused and frustrated: reality was more complex, it required actual analysis and not just theorising based on others' words, A didn't lead to B because your premises only made sense semantically but not in reality.
