Mathematitus – the affliction of reasoning symbolically in a mathematical virtual world disconnected from physical reality.
Once disconnected from physical reality in the world of thought-experiments, peculiar conclusions may sometimes occur. Take the following list of equations:
C = 4L and D = 4L.
Algebraically C = D.
But if C = Cat and D = Dog, then C <> D (<> is “not equal”).
Which means that the nature of L has to be different for Cat and Dog since they cannot be identical.
But if you did not know that C was Cat and D was Dog, then it is quite permissable for C to equal D.
So as long as mathematics is directly linked to physical reality no problems in its use occur, (and then I am making a courageous assumption), but when it becomes disconnected, all sorts of weird outcomes become possible, and is thus a sympton of the affliction mathematitus a thoughter experiences (Thoughter being someone who revels in thought experiments, usually applying pen to paper or chalk to blackboard).
It also happens when the mind invents invisible things like ‘photons’, for example, and so are photons then metaphysical or physical?
Me, I don’t know.
