The alternative being, if we are free of past events, is that we are essentially random beings. Which is the more improbable ? That we are random seems the option that has to go; my experience tells me that things happen for a reason.
There is another alternative, Torri -
We are not entirely free of past events.
We are consciously aware of past events.
We are consciously aware of reasons.
We are not driven by random events.
We are not entirely driven by inevitable reactions to the past.
We are free to choose, to think, to imagine, to contemplate, to draw conclusions, to compose posts, to worship, to make assertions, to argue, to discuss ....
Do you seriously think it is all just driven by uncontrollable reactions to past events over which you can have no control?
Can you not see the evidence that our conscious awareness gives us the freedom to choose rather than just react?
