Insanity

"Much madness is divinest sense." - Emily Dickinson

Do sanity and insanity mean anything, in a relativistic world with consensual-reality leanings?

On the other hand, there are characters referred to (by their players, by other characters, by themselves) as mad.

No absolute; but differing perspectives see things slantwise. Charm-sane may be Up-crazy.

And madness is often holiness' first cousin. Or truth's?

Characters Who Might Be Said To Be Insane

• Sosael - self-described. Mad old thing.
• Twin - What is sanity for a black hole?
• Trilogee - Quite, quite mad for one infected with the Strange...
• Nikolai - Mad doctor. Well, was mad. Still is? Matter of opinion.
• Xa - He's not really crazy, just a little odd.
• Gilgilo - Toymaker engineer driven over the edge by partaking too frequently in the Inspiration.
• Altis - Creator and director of MindLab, a self-serve personality adjustment center in Up.
