I'm vacillating between [definitions](http://www.oxforddictionaries.com/definition/english/disposition) 1, 2, and 4, and also am complicated by the quotes here.
For example, if I use definition 4 (the power to deal with something as one pleases), then does the last clause mean that the onlooker interprets the story in whatever frame or way he pleases, because he has this power?

Yet if I use definition 4.1 (The determination of events by divine power.), then does the last clause mean that the onlooker interprets the story due to "nature's course", or the belief of godly determinism?
