This, and a lot of related observations are discussed at length in articles in [0]. Highly recommended!<p>Personally, I like to imagine concepts as boundaries in the abstract multidimmensional &quot;thingspace&quot; - you can cast and recast them as you like, but some are more useful than others. Some things naturally group together along one axis but spread out when you look along another one. The most important point is, concepts are tools of understanding and communication that we invent, not parts of reality itself. They&#x27;re multiple ways of drawing a map, each with different focus, but each representing the same territory.<p>[0] - <a href="https:&#x2F;&#x2F;wiki.lesswrong.com&#x2F;wiki&#x2F;A_Human&#x27;s_Guide_to_Words" rel="nofollow">https:&#x2F;&#x2F;wiki.lesswrong.com&#x2F;wiki&#x2F;A_Human&#x27;s_Guide_to_Words</a>
