[net.ai] Zadeh Syllogism

From:  Werner Uhrig  <CMP.WERNER@UTEXAS-20.ARPA>

        Expensive apartments are not highly sought.
        Items not in demand are cheap.
                -> expensive apartments are cheap.

or      The higher the price, the lower the demand.
        The lower the demand, the lower the price.
                -> the higher the price , the lower the price.

ergo ??         garbage in , garbage out!

Why am I thinking of Reagonomics right now ????

PS:     at this time of the day, one gets the urge to voice "weird" stuff ...

[The first form is as persuasive as the original syllogism.
The second seems to be no more than a statement of negative
feedback.  Whether the system is stable depends on the nature
of the implied driving forces.  It seems we are now dealing
with a temporal logic.

An example of an unstable system is:

    The fewer items sold, the higher the unit price must be.
    The higher the price, the fewer the items sold.
