That's OK, I have been retired for 10 years and appreciate the value of free time. It is also raining here, again.
"I just don't get the "singleton state."
Here is the argument. Eradicate metaphysical possibilities. There is only a closed system of sensory detection, that is how, and only, how, we know of reality. Some of which is identifiable directly, some indirectly as we have to overcome practical issues in the sensory process. Within this valid and unavoidable confine, there are two fundamental knowns: 1) existence is independent of sensory detection (ie a physical phenomenon is received (forget about the subsequent processing), 2) there is alteration.
This means that physical reality is a sequence, because that is the only way those two manifestations can be fulfilled. Put simply, something occurs, something occurs but is different (when compared). Sequence cannot occur unless the predecessor ceases so that the successor can occur, ie there can only be 'one at a time' within a sequence.
