**attached mail follows:**

I devoted chapters to fuzzy logics and the liar paradox, and

have showed some very original ways to approach problems like

these. I also created a more sophisticated version called

a Time-Space Liar paradox to study the original in more

detail. I also discuss these in terms of fuzzy logics. Further,

the problem is that like other functions that oscillate, there

seems to be "functions" in logic that oscillate. This infinite

oscillation is connected most simply to the trigonometric functions

they are related to exponentials via the sqrt(-1), which in turn

relates to infinite oscillation in more surprising ways which can

be incorporated into logic and specifically might have a bearing

on quantum physics. I did not have time to pursue this last part

in more detail but I did show some pointers in what I thought

intuitively to be direction that logic should pursue.

I will point out some intriguing things below.

the original form of the liar paradox seems to be the woman and the

alligator (see the Paradoxicon by Faletta, and also my book mentioned

above).

An alligator seizes a child playing by the Nile. The mother implores

the alligator not to eat the child. The alligator says "OK, I will

take pity on you. If you guess what I will do correctly, I will let it

go. If you get it wrong I will have it for lunch."

The mother says; "Ok. You will eat my child. That is my guess. Now if

you eat it, I will be right, so you can't eat it and have to let it

go".

The alligator says "No, I can't let it go. If I let go, then your

guess will be wrong, so then I must eat it."

In this case, the truth itself is dependent on the very act of

assigning a truth value to the act, and is easier to see. (more detail

in my book.)

The "problem" in logic is that in the liar paradox, this act that

changes the truth value is the act of assigning a truth value to

the proposition. The Time-Space liar paradox I created shows this

explicitly.

I created some 4-valued logics to fiddle with problems of this type.

For example, one has T, F and B (both, true and false), B' and the other

has T,F and N (neither false nor true), N'. These can be made to

collapse

to the standard T/F logic.

The spin is unknown before the measurement so the statement "it has

spin up or down" is neither true nor false, and then it collapses to

the T/F as as soon as the measurement is made.

OR the spin could actually be oscillating and that is what makes

the state unknowable. When the measurement is made then it catches

the spin at that particular moment.
