I don't remember the exact reference so it might be a bit hard to understand my question, but I'll try to draw the general idea that I understand Levinas to be using.
Levinas puts a kind of connection between two events like this: consider event A is a dynamic event, which can "gain" amount of something (it can be energ, weight, attention, or like Kant puts it "intensive magnitude, i.e. degree"). Now let's say this event can gain so much "magnitude", that it actually overflows with it. This overflow causes a second event, event B, to occur. From here we can say that a case of causation may be called "causation via overflow" (this is my addition, Levinas never treated it as something special, as far as I know, nor have he noted it as some case of causation, but rather simply used it).
I wonder, is this kind of "causation via overflow" is something of an original thought by Levinas, or is it something known that I've simply haven't seen before?
