Hi Stephen P. King I have trouble conceiving an isomorphism (or anything comparative) between something that is there and something that is not. The something that is not there is not the absence of the thing that was, since it has no shape, no location, and cannot be found by a physical search.## Advertising

Hi Roger,

`I sympathize with you but must point out that one must be sure that`

`one's idea and assumptions are correct. What I am proposing is that that`

`Minds are, at the lowest level, a relational structure that can be well`

`represented by Boolean Algebras. There is a duality between BAs and a`

`type of topological space:`

http://en.wikipedia.org/wiki/Stone%27s_representation_theorem_for_Boolean_algebras

`"EachBoolean algebra`

`<http://en.wikipedia.org/wiki/Boolean_algebra_%28structure%29>/B/has an`

`associated topological space, denoted here/S/(/B/), called its*Stone`

`space*. The points in/S/(/B/) are theultrafilters`

`<http://en.wikipedia.org/wiki/Ultrafilter>on/B/, or equivalently the`

`homomorphisms from/B/to thetwo-element Boolean algebra`

`<http://en.wikipedia.org/wiki/Two-element_Boolean_algebra>. The topology`

`on/S/(/B/) is generated by abasis`

`<http://en.wikipedia.org/wiki/Basis_%28topology%29>consisting of all`

`sets of the form`

\{ x \in S(B) \mid b \in x\}, where/b/is an element of/B/.

`For any Boolean algebra/B/,/S/(/B/) is acompact`

`<http://en.wikipedia.org/wiki/Compact_space>totally disconnected`

`<http://en.wikipedia.org/wiki/Totally_disconnected>Hausdorff`

`<http://en.wikipedia.org/wiki/Hausdorff_space>space; such spaces are`

`called*Stone spaces*(also /profinite spaces/). Conversely, given any`

`topological space/X/, the collection of subsets of/X/that areclopen`

`<http://en.wikipedia.org/wiki/Clopen_set>(both closed and open) is a`

`Boolean algebra."`

`This made complete sense to me once I realized what the Stone`

`spaces "look like": a collection of particles in an emptiness (frozen in`

`time). (A Cantor dust <http://en.wikipedia.org/wiki/Cantor_set> is a`

`Stone space.) A nice illustration of the physical universe once we strip`

`away of the detail. When we take change into account we get a succession`

`of Stone spaces and BAs. The direction of the "arrows" of evolution of`

`these are in opposite directions. BAs evolve by "looking backwards" to`

`be sure no new proposition contradicts a previously accepted`

`proposition. This property alone makes this hypothesis very appealing as`

`it leads naturally to a reason why there are no "White Rabbits"`

`(spontaneous events that present contradictory information, like a`

`"White Rabbit" popping out of nowhere).`
