Is there such a thing as the "nature" or "essence" of things? Do objects, people, or events have an inherent "being" or "reality"?

I have been wondering whether there is a nature or essence to everything, whether we can know it and if we care. I see many ways of looking at it, but I'll lay out my views as best I can. Please tell me if you have other views. Thank you.<br><br>It is impossible to know the nature or essence of anything. We can only see things from our limited human perspective. We can only make assumptions and not know anything for sure. For example, we think we know the nature of water because we see it everyday and we know it is liquid at room temperature. But what if the temperature of water changes tomorrow? Would we know it's still water?<br><br>On the other hand, we can make assumptions about the nature of things based on what we know. For example, if we see something moving at high speed, we would assume it's a car or a plane or maybe a ghost. But what if we see a meteorite moving at high speed? Would we assume it's a ghost too? No, we would know it's a rock.<br><br>We can't know the nature or essence of things because we can't see them clearly. We can only see things from our limited perspective. We can make assumptions based on what we know, but we can never be sure. We can never know the true nature or essence of anything. That's the only thing we can be sure of.<br><br>What do you think?<br><br>**tl;dr:** It is impossible to know the nature or essence of anything. We can only see things from our limited perspective.
