I am so stupid

Those *who* move, not "that move." It doesn't have to be in bad English just because it's an Arabian proverb.

You're a douche. Was that written well enough for you?

I don't get it.

Um John: Those that move is perfectly acceptable english, if you consider the idea that they are moving not only themselves (in which case it would be those *who* move), but they also have the potential of moving others (i.e. those that are movable) Basically the proverb says there are people who are narrow minded and live entirely within social norms, there are people who happen to be living withing social norms but have the capacity to escape, and there are those who are unable to conform to these social norms, and have the power to affect not only themselves but others in the second category. Therefore, those that move is perfectly acceptable english.

@ Re: John. That's not so. "Who" is correct because even if, as you suggest, the moving involves others, it still only involves people and "who" is always the correct word when dealing with people. Only with animals or objects should "that" be used.

1. I think the meaning is that there are some people, like the poor, the ignorant, the unprivileged and unintelligent who are just stuck in their rut, never to move to a higher station. Then there are those who have the intelligence or talent to climb the social, monetary, and power ladders. Then there are those who make the moves. They are in a good position and make things happen. Another interpretation could be that the third group is made up of those who successfully transform from one station to another, be it cultural, spiritual, or otherwise. 2. Cite sources for any grammar arguments.

@Steve So what are people then if not objects or animals? Vegetables? Minerals? Abstract theories of wealth redistribution in 20th century Albania?
