Remember the query about time being *the* fourth
dimension, and how come we don't differentiate
between the other three?  I.e. what is *the*
first dimension?  To a Flatlander, there's no
question which dimension is the third dimension.
He already knows that there are two, but the
one which is orthogonal to the ones that he knows
about is clearly the third one.  Wouldn't it be
true that one can't differentiate between dimensions
in which he can freely move?
