这是第11段的最后1句，定位柏拉图的人的分类学在实现理想国的地位。它是神话，是种故事，是种共识，也是无形的束缚。
Perhaps with this "royal fable" we shall secure a fairly general consent to the furtherance of our plan.
也许，这种”高贵的寓言“能帮我们让大家推进我们的计划达到相当普遍的共识。
细节解析
furtherance: the act of helping something to become more successfully or advanced促进；推进；增进
But Mr. Bolton is an inveterate disrupter, eagerly upsetting the status quo in furtherance of his policy goals.
但博尔顿的确是急于打破现状，推进他的政策目标并且积习已深的破坏分子。
整段总结
这段继续前段的大淘汰，并指出要安置淘汰者的原因及方法。这个方法就是柏拉图独创的人的金属属性分类法。
通过首次“大淘汰”者将继续接受额外10年的教育与训练，涉及身体、心灵及品质。接着，他们就面对第二次考试，无比第一次考试苛刻。落败者将成为国家的辅佐者、行政助理或军队长官。现在，在这些大淘汰中我们应该需要千方百计地说明那些遭淘汰的人心平气和地接受他们的命运。有什么可以阻止那些初试考试中遭淘汰的人——初试的多数人以及第二次考试中为数较少的却更为精力充沛且能干的人——扛起武器击碎我们的乌托邦，使其成为腐朽的回忆？有什么可以阻止他们当场就建立一个仍只靠数量或武力统治世界从而永无止境地重演那虚伪民主的病态闹剧呢？宗教和信仰是我们唯一的救赎：我们将告诉这些年轻人，他们所属的分层是上帝的旨意，不可改变的——即使流干眼泪也无法抹去其中的一个字。我们告诉他们有关金属的神话：
公民们，你们本是兄弟，但神赋予你们不同的本性。有些人具有发号施令的权力，神以黄金铸就他们，因而拥有最高荣誉；另一些是由白银所造，将成为辅佐之人。还有那些人注定为农夫及工匠，神以铜铁造就他们；这些种属一般会由其子女继承。然而你们源自同一祖先，黄金父母有时会有白银子女，或者白银父母会有黄金子女。神谕宣示……如果黄金及白银父母的子女掺杂了铜或铁，那么自然需要降阶。而统治者绝不能因为自己的孩子沦落为农夫或工匠而心怀怜悯，正如出身工匠阶层的人也可能被提拔重用，从而成为护卫者和辅助者一样。因为神谕有言：当铜铁之人守护国家时，它必将灭亡。
也许，这种”高贵的寓言“能帮我们让大家推进我们的计划达到相当普遍的共识。

The Story of Philosophy《哲学的故事》第1章Plato第7节VI. The Psychological Solution第11段第14句：
Those who pass this first test will receive ten more years of education and training, in body and mind and character. And then they will face a second test, far severer than the first. Those who fail will become the auxiliaries, or executive aides and military officers of the state. Now it is just in these great eliminations that we shall need every resource of persuasion to get the eliminated to accept their fate with urbanity and peace. For what is to prevent that great unselected majority, in the first test, and that lesser but more vigorous and capable second group of Eliminees, from shouldering arms and smashing this Utopia of ours into a mouldering reminiscence? What is to prevent them from establishing there and then a world in which again mere number or mere force will rule, and the sickly comedy of a sham democracy will reënact itself da capo ad nauseam? Then religion and faith will be our only salvation: we shall tell these young people that the divisions into which they have fallen are God-decreed and irrevocable — not all their tears shall wipe out one word of it. We shall tell them the myth of the metals:
"Citizens, you are bothers, yet God has framed you differently. Some of you have the power of command; and these he has made of gold, wherefore they have the greatest honor; other of silver, to be auxiliaries; others again, who are to be husbandmen and craftsmen, he has made of brass and iron; and the species will generally be preserved in the children. But as you are of the same original family, a golden parent will sometimes have a silver son, or a silver parent a golden son. And God proclaims … that if the son of a golden or a silver parent has an admixture of brass or iron, then nature requires a transposition of ranks; and the eye of the ruler must not be pitiful towards his child because he has to descend in the scale to become a husbandman or an artisan, just as there may be other sprung from the artisan class who are raised to honor, and become guardians and auxiliaries. For an oracle says that when a man of brass or iron guards the state, it will be destroyed"(415).
Perhaps with this "royal fable" we shall secure a fairly general consent to the furtherance of our plan.
浙江大学译本：估计有了这样一个“庄重的神话”，我们的计划就能取得一个相对广泛的共识而得以继续推进了。
