Let's use a simple concept, "ball." In English, what is a ball? It is usually a spherical object, suitable for throwing from one person to another. It's not always spherical, most people would call a football a ball and it's not spherical.
Any concept--a mindful classification of extant objects--is built of a definition. That definition is comprised of the essential attributes that the mind believes are the defining characteristics of the object. The object itself is not the definition, the map is not the territory. For most English speakers, "throwable between people" is an essential characteristic of being a ball.
Now consider a giant spherical object, say 50 feet in diameter and nearly spherical. Is that a ball? Or even larger...is the moon a ball? Most people would say such an object is "ball-shaped" because it's spherical but would not call it a ball because it cannot be thrown between two people. Are they right?
The point is that this is not an ethical matter. It is a decision, a choice. A person has no moral failing if that person chooses to conceptualize a ball as any spherical object, or even nearly a spherical object. To that person, the moon is a ball. Most of us would say the moon is "ball-shaped" but is not a ball. That's because we choose to consider "able to be thrown" as an essential characteristic of being a ball. So a football is easily a ball and the moon isn't. Neither is good nor bad, neither is right nor wrong.
There's a benefit to shared language...we can communicate with each other. We also say, "A man has balls." Those balls are neither spherical nor are they thrown, yet everyone knows what is being said. They know what the object of the concept is, they know to what in reality it refers.
And so it goes with all concepts. Naturally the more complex the object and the more abstract the referent, the more divergence there will be between utterances. Consider "justice," "freedom," "peace" and on and on...consider "good" and "bad" themselves.
That's the conclusion here: ALL meaning is created in a single, individual mind. This is a fact of reality, one which will yet prove critical in understanding how our society has gone so utterly insane.
