Logic, including Prolog, has no concept of time. Creating temporal
logics is a subject of research.
You might like to actually read the entire paper. We have to stop
thinking of time as a "dimension" with material substantist
implications. The point is that logic's version of time is the chaining
of implications, like what we see in law as stare decisis
<http://en.wikipedia.org/wiki/Precedent>. It flows in the opposite
direction of time. Logic looks back to be sure that any new event does
not generate a contradiction and material states flow forward giving us
the notion of causality. This also makes the relation between
thermodynamic entropy and information entropy make perfect sense and
prevents the White Rabbit problem without even trying hard. Inconsistent
event are simply not allowed to occur, but this forced "consistency" is
over spans that do not just look at the human level of things.
This is how we get a symmetric ontology and a consistent dualism,
unlike the Cartesian failure. Time flow one direction for matter and
implication flows in the opposite direction for its dual. Take this
duality to the ultimate level and the differences, flows and change
vanishes, leaving a neutral monism ala B. Russell's idea. Bruno is only
looking at the logical side of the dualism that Pratt sketched out in
his work. I have laboring hard to get Bruno to see the necessity of the
"Nature, to be commanded, must be obeyed."
