Just read the post over and was pondering something...
Shouldn't Paladins be required (if there should really be any requirement at all?) to be Neutral Good. I always thought Paladins answered to a higher power than man's law...
First of all, being lawful doesn't mean being bound to a particular man made set of laws. It can, but what it really means is that you espouse a public widely agreed upon code of conduct which in some form or the other states "the needs of the many outweigh the needs of the one or the few". The law, and the collective society of beings which uphold that law, are therefore most important than any of the individuals of that society.
So, whether you follow a man made code or a divine code, so long as its not a personal code or any other sort of code which elevates your choice higher than the code or your society higher than the code that defines, then you are lawful.
...and this higher power could require them to do things that are not within the laws of man to achieve a greater good.
And that would still be lawful. What would not be lawful is if the things that were required were not pre-specified, and the follower of the diety would not know what sort of thing would be required of him until the situation presented itself. What would not be lawful is if the code was not subject to scrutiny, so that an observer couldn't tell whether or not the individual was following a code or not. What would not be lawful is if the code is subject to change at any point, particularly according to the whim of individuals. But a code which publicly contains a meta-law, "This section 'Obedience to Mortal Rulers' is invalidated under certain provisions. See section 3.7. When invalidated, you are still required to obey the strictures of section #1 and #2, 'Obedience to Higher Powers'." is still lawful.
Taking this a little further, no man is infallible and a paladin is still a man. So from that reasoning even the code he/she follows isn't infallible...
What if the law was written by a diety? BTW, the dieties of D&D aren't infallible either. We aren't dealing with monotheistic benevolent and all powerful creator dieties here. However, infallible or not, you probably can trust someone with 40 INT and 40 WIS to write pretty darn good laws.
...and the paladin may have to break even his own code in serving the greater good.
Of course he might. He'd be very reluctant to do so, but that is why he is 'lawful good' and not 'lawful neutral'. He's making a comprimise between law and good because he ultimately believes no good can endure in the absence of law. But he also understands (or believes) that no law can endure in the absence of good character, since an evil spirit can always prevert the intention of the law (or so he believes).
A lawful neutral can't break his own code and remain long LN, but other lawfuls in extremity can. What a LG can't do is break his own code in order to do something evil, no matter how justified the ends may seem to be. Also, even when a LG had to go beyond the code, he'd consider himself operating in the blind and would immediately seek (if he could) the advise of 'higher authority' to make sure he correctly understood the situation and had acted appropriately. In other words, he 'turns himself in' and awaits judgement rather than relying wholly on his own judgement.
Neutral good seems to define this thinking better IMHO than Lawful Good.
Only if you can't differentiate between being good and following laws.
Oh yeah and Jack Bauer is the ultimate paladin. He does what is for the greater good, no matter what the cost.
Jack Bauer belives that the ends justify the means. I haven't watched the show enough to make a statement about his alignment, but I know enough about him to know it isn't LG.
In my mind he epitomizes the hard choices and necessary long term thought, to determine what exactly is the greater good, that have prompted me to play paladins in the past.
There are some schools of thought that way. However, IMO, a LG would not believe that in general he had the authority to decide what exactly is the greater good. That would be elevating himself above both the law and society.
