Replying to LO23493 --

>I cannot identify something which is not real.
and
>WE CANNOT ESCAPE REALITY.

Dear At,

here you expressed, what makes the law of the excluded middle (LEM) so
important to me.

Let A be identified as something that is real.

Then NOT A consists of ALL BUT A.

The LEM states that NOT NOT A 'cannot escape reality'. It has to be A
again.

Without LEM, A could be real (as A) and not real (as it's double
negation). But: A and NOT A is ALL. Tertium non datur.

This is the contribution of sureness to reality. Otherwise, how could one
identify anything at all?

(To avoid misunderstanding, I should repeat, that the place of LEM is in
sureness. LEM doesn't make sense for liveness, wholeness, fruitfulness and
openness. I am not sure about the relation between LEM and otherness and
spareness.)

Liebe Gruesse,

Winfried
