How mad are you?

Its an interesting question that was posed to me in a roundabout way by
a friend of mine recently. She asked the question in relation to a scale
of subjective measurement of madness. I answered her analytically and
explained that a definition would be necessary but her scale was purely
subjective.

I'd never have considered myself mad until someone else told me.
Madness, in part or perhaps wholly, is being in a delusional state
though in actual fact it is an observation or detection of the
delusional state rather than the existence of one. To self-assess as
"pretty damn mad" creates a problem because insight seems to quell
madness. Essentially a person who recognises their delusional state is
not mad. Perhaps, as has been said before, a mad person would say
they're not mad, perhaps.

So how mad are you?
