A Three-dimensional, Eight Quadrant Spaceflight

It occurs to me that, as useful as two-dimensional, four-quadrant diagrams are (as, for example, when compared to one dimensional analyses like 'The Political Spectrum-not), the traditional English wedding vows created a three-dimensional space.

Thus, the three dimensions are:

   For better, for worse;

   For richer, for poorer;

   In sickness and in health.

So, the apparently ideal place in this eight-quadrant space is:

Better, Richer, Healthier.

Or is it?

When compared to the Hell-quadrant:

Worse, Poorer, Sick

This appears so . . . but . . .

The evidence is *not* that 'richer' is good but 'more equal' is: the evidence is in The Spirit Level book, many subsequent books by other authors and the sequel by Spirit Level authors, Richard Wilkinson and Kate Pickett, The Inner Level.

So, a useful three-dimensional space, I hope.
