Diameter

There is method in madness
for even chaos requires frames
frames need logic
and nothing exists in vacuum

logic can be illogical
perception requires intuition
which stems from experience
of reality and the unreal

the unreal is a vision
of an unhealthy mind
while viewing the real world
requires a sound mind

madness exists in the mind
insanity is incomplete
without some kernel of sanity
viewed as concentric circles

so the question is
for you my friend
which has the larger diameter
the sane or the insane
