There is something similar between the particles that make up our hand, yet there are differences too. When we look, we see, and what we see are our fingers, palm, and wrist. We look and we see skin, and when we look closer, we see that there are layers of skin. We name them. We see at the ends of the epidermis layer of our skin over the bones in the digits is the part fartherest from the knuckle and air are our finger nails.They are still in a different location and moving in different directions.
They are different. They are in different locations and moving in different directions.
Why do we only count how they are the same and ignore how they are different?
That is a capricious decision.
These differences are there, and it's these real differences that drive our classification systems. To say it's arbitrary is to deny a basis of reason anchored in reality behind the lines we draw. The real differences that exist do not vanish when people with minds to detect them vanish.
