How Can a Declining Civilisation Be Saved?
From A Study of Our Decline by P. Atkinson (3/2/2016)

Mental Decay Has Already Occurred
If you were to observe your aging mother attempt to boil water by placing an electric kettle on a gas cooker, you would immediately know that she was losing her mind. And that it would be futile to try to remedy her mistake by instruction or demonstration. The act would be unmistakable evidence of mental decay for which there is no possible treatment (the loss of memory means loss of brain tissue), and her condition would only get worse. And what is true for the individual is also true for the community. The behaviour that reveals social decline is undeniable evidence that the communal mind has already decayed.

Decline is Communal Senility
Social decline is the impact of a growing deterioration in the understanding of the community; the community is losing its mind along with its strength and becoming senile:

Impossibility of repair
A senile community is like a senile person: though the mind is rotten, the body may appear intact, still have strength and vitality, and so lend itself to the notion of being curable. But the simple truth is that the understanding that occupied the body is now dead. Nothing can bring it back. It is possible in theory for a diseased brain to be repaired by replacement of some or all of that organ, but this would not return the lost memory or lost personality and would create a new understanding—a treatment that could only be done by another intact understanding. Though such an option may be open to a senile person among friends and relatives, it is unavailable to a senile community.

Sanity and strength permanently lost
The impact of senility, increasing mental confusion and decreasing strength, which must become fatal to the community, are impossible to repair:

Nothing Left to Save
When the symptoms of social decline appear the people who gave the civilisation energy, intelligence and made it an asset to humanity, no longer exist in any numbers. Their place has been taken by a race of foolish cowards, who can only dissipate the accumulated wealth and wisdom they have inherited. Though the true character of these new citizens will initially be disguised by the restraints imposed by their inheritance of customs, manners and beliefs, these will be rapidly discarded by the impatience of subsequent generations.

Can Only Promote Lies and Injustice
To attempt to help such a community is to aid and abet people who hate truth and justice. Those citizens, who feel their duty impels them to try, are taking grave risks for no purpose. Their individual efforts cannot make up for the shortcomings of their society, but they will be punished for their attempts, and this is demonstrated in no uncertain manner by contemporary and historical examples.

By 2015 Most Citizens of Western Civilisation Are Fools
Our civilisation has been declining since the late Eighteenth century (see “A Study of History“ by Professor Arnold Toynbee), which means that since then the majority of citizens of western civilisation have been selfish—for selfishness is the influence that rejects moral restraint, along with its associated beliefs. In place of the guide of tradition the selfish rely upon feelings to recognise right from wrong and fact from fancy. Now, after more than two centuries of discarding and reversing traditions, most citizens are fools who can neither tell right from wrong nor fact from fancy. A result predicted by the bible and confirmed by failing literacy, inane university student concerns, and the poor quality of social media.

Only Changes for the Worse Accepted
Naturally it is possible to persuade contemporary citizens to accept change, but all such change must appeal to an understanding guided by feelings not reason. So regardless of any claim the public may make to the contrary, they will be unable to resist the compulsions of their instincts; the terrors of the fearful are beyond appeals to reason, which is why the threat of Global Warming is so popular and withstands all attempts at debunking. Any citizen who persists in denying that Global Warming is a real threat is either ignored or persecuted. So any attempt to curtail the unnecessary costs and limitations imposed in the name of Global Warming will be resisted, whereas further increases to such costs, or extension of restrictions, will be accepted as a required imposition to save the world.

In the same way, those parents who indulge their offspring, and so create odious citizens, are also impossible to change, except for the worse. Anyone who dares point out to a modern guardian the inadequacies of their child raising technique, or that their progeny are spoilt brats, risks unpleasant repercussions for no good reason. The proud parent will remain an adoring parent regardless of any argument advanced to the contrary. Modern parents will reject any imposition of discipline upon their favourites that could improve their child's character, but will accept any and every move that panders to their charges, even though it further weakens their offspring's character.

Nowhere is the urge to self-destruction more obvious than in the way the general public respond to unemployment. Despite the fact that our community is being slowly impoverished by unemployment enforced by an irresistible tide of automation, the public resist any attempt to alleviate the problem. Politicians still find it increases their popularity by increasing the restrictions on paying the dole, even though this must make everything worse for everybody. Whereas the notion of paying the dole to every citizen without a wage is treated as an anathema, despite the fact that this could only benefit everyone. The unemployed do not eat money but hand it on to others by spending it. An act that is repeated throughout the community so supplying extra money to everyone. This simple effect is ignored because of the feelings of the community towards the unemployed. Regardless of the truth, the community will only accept changes that punish the unemployed even though this makes everybody poorer and further accelerates the plunge into communal poverty.

This means that the decaying understanding that is impoverishing and deluding our community is beyond the ability of its citizens to repair, for they will insist upon making things worse.
