"4 and 6 are different, therefore by definition they are the same"
It doesn't sound quite as good when you say it like that, does it?
Now, you could think of it like a vector in that "4 and 6 each differ from the other by the same magnitude, ie. 2, but in opposite directions", or in general terms, "A differs from B by exactly the same amount as B differs from A, but in reverse".
With that out of the way, my question to you and others is this:
If (as you assert) two things being different is, by definition, the same, is the opposite also true? What about multiple things?
Hey Paul.
My statement was more about classification.
We geoup things that are " the same" and things that are not are classed as "different". How ever, by then putting them in the group of things "different" to that we are looking, they are all share the common label of "different". Therefore by defining them as that, they are all "the same" by virtue of what we have called them.
TL;DR Exactly, same colour is quite different to same classification.
My point however was that you speak of "difference" as being a property that each thing has, and by one thing having that property that makes the other thing also have the same property.
I assert that either you need to consider difference as a property of the comparison between two things (hence there is only one difference to be spoken of, and saying "they are the same" is nonsensical), or you use my vector analogy and assign each thing a difference relative to the other.
In the latter case, by definition, they only differ by the same magnitude, but the direction is opposite. Applying this to your coloured cube analogy, say you wanted to alter a red and blue cube to be the same, you can either make the red one "more blue and less red" or you can make the blue one "more red and less blue", the vector between them is the same, but opposite direction.
