I've often seen it suggested that True Neutrality or "balance"-oriented Neutrality, as spelled out in the original AD&D books, is nonsensical. The point of this thread is to explain why I don't agree.
First, what is True Neutrality? From the AD&D PHB (pp 20, 33) and DMG (p 23) (with some resequencing by me):
The reason this is sometime seen as nonsensical is because of what is taken to be an implication that the true neutral must support evil people, when good threatens to predominate, as much as help good people when evil threatens to predominate. And how can it be rational to think that evil is worth supporting, or that too much good is a problem?
But this diagnosis of nonsensicalness results from looking at alignment in a "static" way in which each alignment is understood to be as it claims to be - so that (say) the LG don't just aspire to be good, but are interpreted as actually being good. This "static" (or metaphysical) view of alignment is encouraged by other aspects of AD&D (eg the system of outer planes set out in Appendix IV of the PHB) and is reinforced by later D&D writings. But it leads to all sorts of problems, of which the nonsensicalness of true neutrality is just one.
When alignments are seen in a "dynamic" or aspirational/motivational way, though, then true neutral needn't be nonsensical at all. When alignment is understood in this way, the LG aren't good as such. Rather, the LG are those who (i) are committed to human wellbeing and (ii) believe that social order is the best, perhaps only, way to achieve that. The CG, on the other hand, are equally committed to (i) but disagree vehemently in respect of (ii) - they believe that individual self-realisation is the only path to wellbeing, which will be crushed by excessive order. The LE agree with the CG about (ii) but are indifferent to (i) - they are quite happy to crush individual self-realisation and wellbeing if that lets them impose their yoke upon the world. And the CE agree with the LG that social order tends to produce widespread wellbeing and to constrain the brutal and indifferent exercise of individual will - hence the CG oppose social order, precisely because they want to indulge their individual wills indifferently to the interests of others.
If alignment is understood as a set of aspirations - for widespread wellbeing (if good) or individual self-advancement (if evil) - coupled with a set of beliefs about how to achieve that - via social order (if lawful) or individual self-realisation (if chaotic) - then true neutrality is the view that all such belief and aspiration is misguided, because human action is incapable of improving upon the natural order, which is already maximally harmonious, and will only lead to suffering if not kept in check. So the true neutral doesn't oppose the LG person because they think there is something wrong with human wellbeing, or that the aspirations of the CE person are worth upholding; rather, the true neutral opposes the LG because they think the LG person has a misguided optimism about the feasibility of deliberate action to improve wellbeing, which if given its head will only lead to disharmony and hence to suffering. The true neutral person is no more sympathetic to the CE person than is the LG; but unlike the LG, the true neutral person is confident that nature will restore the balance, undoing any imbalance the CE person gives rise to. And the true neutral person thinks that the active opposition the LG person mounts against the CE is itself going to be a source of disharmony and hence suffering.
When seen in this way, true neutrality is extremely conservative (or, at least, passive and hostile to action) but not nonsensical. And while ENworld board rules preclude actually saying very much about real world analogues of the true neutral outlook, it's pretty easy to recognise some of them.
First, what is True Neutrality? From the AD&D PHB (pp 20, 33) and DMG (p 23) (with some resequencing by me):
Absolute, or true, neutral creatures view everything which exists as an integral, necessary part or function of the entire cosmos. Each thing exists as a part of the whole, one as a check or balance to the other, with life necessary for death, happiness for suffering, good for evil, order far chaos, and vice versa.
[Druids] are . . . absolute neutrals . . ., viewing good and evil, law and chaos, as balancing forces of nature which are necessary for the continuation of all things.
The neutral sees all other alignments as parts of a necessary whole [and] looks upon all other alignments as facets of the system of things. . . . Nothing must ever become predominant or out of balance. . . . Thus, each aspect - evil and good, chaos and law - of things must be retained in balance to maintain the status quo; for things as they are cannot be improved upon except temporarily, and even then but superficially.
Nature will prevail and keep things as they were meant to be, provided the "wheel" surrounding the hub of nature does not become unbalanced due to the work of unnatural forces - such as human and other intelligent creatures interfering with what is meant to be. Within this naturalistic ethos, humankind serves a role also, just as all other creatures do. They may be more or less important, but the neutral does not concern himself or herself with these considerations except where it is positively determined that the balance is threatened.
