In my understanding, quantum logic is also based on the uncertainty. In
your example, I do not see any differences between fuzzy logic and the
quantum one.

And if the fourth God tells only things which can be categorized
neither as truth nor lie, e.g. he is right a little bit, etc. Is he the
Fuzzy God? I really confuse quantum logic with the fuzzy one when the
dimension of time is added into the party.

A loof from the party discussed above:

What do you think about (what ever) leaps in quantum logic and in fuzzy
logic?

There is the quantum leap (in quantum logic ?)

What about the qualitative leap? Let me return to the relation between
local (micro) and global (macro) levels. When do you pass the 'boundary'
between micro (local) and macro (global) levels? Or is there a 'no man's
land' between both levels? A differenciation of local levels from the
global ones is very important for every extention.

Cheers,
