A matter of choice

There is a lengthy discussion of this in the fourth book of the Talmudic Logic series. First of all, it has nothing to do with choice. The Ramban in Gittin 26 even writes that in matters that depend on a person, there is no choice for the individual. Here I will just say briefly that in simple terms the choice does not act causally backwards, unlike a condition that does. The Yanark choice defines the object to which the legal action applies. For example, writing a divorce for the one who will come out first was originally written for the same woman who was meant to come out first tomorrow. When that happens tomorrow, it only becomes clear who the woman for whom the divorce was written is. It is not really retroactive. It is difficult to elaborate here.
