Okay. First off, I want to appologise for this ahead of time: English is not my first language.
Now I'm cross-posting this from /lit/ because I think this counts somewhat as a scientific problem, specifically in regards to the Species Problem:
So recently, I read Charles Darwin's On the Origin of Species. It got me thinking about evolution and how one species can change over time into another one. And I realized that gradients like that everything. AND THIS MAKES ME REALLY ANGRY! Why? Because now I find it hard to define anything. Take the image attached. I'm sure we can agree that on one side, it is blue, and on the other side, it is red. But at what point does red turn into blue? You can't mark off any specific line because at any line, the color directly on either side would be nearly identical. SO IF WE CANNOT DRAW A LINE, HOW DO WE DEFINE RED OR BLUE?
More relevant to the book, is the definition of human. You probably consider yourself to be human. You probably consider your parents to be human. And their parents. etc. But if we go back far enough, we get something that you wouldn't be willing to call human.
But let's say we do that in order. We keep going back a generation until we hit something that's not human. But we just called the child of this thing, human. And assumable, they'd be very similar things. So how can you justify calling the parent not human?
I DON'T UNDERSTAND GRADIENTS AND IT'S RUINED MY WORLD-VIEW BECAUSE I CANNOT GIVE ANYTHING CLEAR DEFINITIONS ANYMORE. HOW DO I DEFINE RED VS BLUE? HOW DO I DEFINE HUMAN VS NOT HUMAN? WHAT IS THE DIFFERENCE BETWEEN A TABLE AND A CHAIR?
