But how do you explain sight to a man born blind? (It's even harder to do from a philosophical standpoint than a practical one, that.)

Perhaps replacing the word explain with restore might be more meaningful (and far more measurable in fact)?

So do we fight for it? The banner of ambiguity will draw few riders... the rallying cry of "We're smack in the middle! Hear us!" will drown out the noise of our battle trum... bassoons (because they're not wholly brass, nor wholly woodwind, of course*)... and when the battle is over, will anyone know there ever was one?

*or is that oboes? I can never remember.

I don't think it's the literal interpretation of being midpoint that is important but instead the implications of it. Maybe instead of using musical instruments as our mascot, I think alloys would be far more relevant. What makes steel useful is its inherent properties that are attained through a mixing of iron and carbon. Or perhaps we could consider the organisms in the animal kingdom that have a dual set of characteristics so to speak. For instance, lungfish can obtain oxygen from both the air and the water. Whales have fins and tails like fish do, but they still breathe oxygen from the air like every other mammal.
