We believe that every thing and every event must have a cause, that is, some other thing(s) or event(s), and that it will in its turn be the cause of other effects. So how does a cause lead to an effect? To make it much worse, if all that I think or do is a set of effects, there must be causes for all of them going back into an indefinite past. If so, I can’t help what I do. I am simply a puppet pulled by strings that go back into times far beyond my vision.
