Think of an event – let’s call it X. X is almost never the result of a single cause. Multiple other events happened to bring about (cause) X. This is a rejection of a norm of monocausality.
What if X is in the future, some desired state that has not yet happened? If monocausality is usually not true, then the idea that the event or outcome we desire will happen as a result of a single factor is also unlikely. Said otherwise, the outcome we desire will likely have multiple inputs to bring it about.
