Which looks pretty clear cut; an outright statement that their ability to use the Force has diminished. It has been argued before however that Windu was not making a general statement about Force use, but in the context of talking specifically about foreseeing the future. I've never quite gotten this interpretation; from watching the scene, it looks pretty clear that he's talking about the general cause (diminished Force ability) to their problem (not foreseeing the future). If it was a problem that they were specifically having trouble seeing the future, he would have spoken of it as such.Attack of the Clones wrote: YODA: Blind we are, if creation of this clone army we could not see.
WINDU: I think it is time to inform the Senate that our ability to use the Force has diminished.
This passage, besides giving an origin as to why this event is happening, looks to reinforce the alternate explanation about only affecting farseeing abilities, since it talks about Jedi "perception." But then, even the word perception has many meanings in the context of a Jedi's abilities. After all, a Jedi's powers comes from the Force, and if their ability to connect to it, to "perceive" it, is diminished, then they are diminished as well. Even going with the interpretation that only the Jedi's farseeing abilities are affect, that is still going to have a drastically negative effect on them. On the strategic scale, it means being unable to foresee events like an invasion or planetary disaster. On a tactical scale, it means being more vulnerable to ambushes, less able to deflect and dodge attacks, etc. But this phrase is also used elsewhere in another meaning.Revenge of the Sith novelization wrote: With the Jedi Order overextended, spread thin across the galaxy, each Jedi is alone, surrounded only be whatever troops he, she or it commands. War itself pours darkness into the Force, deepening the cloud that limits Jedi perception. And the clones have no malice, no hatred, not the slightest ill intent that might give warning. They are only following orders.
Again we see the phrase "Jedi perception", except this time it is perception "of the Force." And it is used in the context of Mace trying to telepathically contact his former padewan, who was back on his home planet and had gone all Apocalypse Now on them. Clearly, whatever the dark side is doing to the Force, it is affecting more than just Jedi abilities relating to seeing the future.Shatterpoint wrote: Mace nodded silently..."It's...maddening, Master. If only...I mean, ten years ago, we could have simply reached out-"
"Cling to the past, a Jedi cannot," Yoda interrupted sternly. His green stare reminded Mace not to speak of the shadow that had darkened Jedi perception of the Force. This was not discussed outside the Temple.
Here we see further evidence, in this case Mace failed to stop a colleague from getting shot, of Jedi's abilities weakened. Obviously, if you are having trouble seeing the future, your ability to operate as a super-police/ninja/general is diminished. Of course not everyone was affected equally; Mace might sound moody now, but he's a Jedi Master, and still able to kick ass in ridicules BAMF ways later in the book. But the rank-and-file were noticing it too.Shattepoint wrote: Not because he was responsible for her death. It ate at him because he wasn't.
He'd had no idea she was about to walk into a blaster bolt. The Force never offered the faintest hint of a clue. No trace of bad feeling - or rather: no hint that all the bad feelings he'd had were about to add up to something much, much worse.
Nothing. Nothing at all. That's what sickened him.
What happens to a Jedi when he can no longer trust the Force?
Here again we see Jedi Force powers, specifically telekinetic abilities, are being affected as well.Dark Lord: The Rise of Darth Vader wrote: Shryne hurried to Climber's side while the spec-three was moving through the room, making certain no further surprises awaited them.
Yoda or just about any other Jedi Master would have been able to rid Climber of the battle droid with a Force push, but Shryne needed Climber's help to move the sparking carcass aside. Years back, he would have been able to manage it alone, but no longer. He wasn't sure if the weakness was in him or if, with the death of every Jedi, the war was leaching some of the Force out of the universe.
From the perspective of a Jedi teacher. Obviously, if you are a 'light side user' and the Force is being 'clouded' by the dark side, you might have some trouble using it.Yoda: Dark Rendezvous wrote:For the first time since the Sith War, there would be a generation of Jedi Knights who grew up surrounded by a Force clouded by the dark side.
Now this topic is often so hotly disputed primarily because it comes up in versus debates about how to treat the Jedi, whether their poor showings during this period is because they naturally suck and would get beat up by an old woman, or they're all Supermen able to break planets apart but had their true potential held back. However I think everyone can agree that the dark side was affecting the Jedi in a negative way during the Clone Wars, specifically by design due to Palpatine's plan, and that in whatever alternate scenario they get put in this probably won't be the case. This doesn't mean your average Jedi is just gonna go around effortlessly snapping their opponent's neck, but that a little leeway might be in order in what they can and cannot do.
