+So far as temporal successions of concurrences (within the present 
 world) are concerned, any permitted concurrence may succeed any other 
 permitted concurrence. The succession of a concurrence by itself is 
 excluded, meaning that at the moment, a $V_1$, is defined as lasting from the 
 time the eyes open until the time they next close.
