Don't know. It's probably not true, though, otherwise there'd be no point in endowing beings with the ability to act and make decisions, because decisions and actions clearly influence what happens, and if they don't, then they're superfluous. Well, I guess you could say the decisions and actions are only for the things that are neither meant to be nor meant not to be, but, eh.. you can decide to kill yourself, then suddenly that means that everything that could have otherwise happened wasn't meant to be? I don't think so.
