Fooloso4 wrote, regarding Plato's thought:
The cosmos is a natural whole and the Good is not outside that whole, and so, to call it supernatural is misleading. What is important for any reader of Plato to know is that there is no single, fully consistent and coherent logos that runs through and informs the dialogues. Every logos or account is limited, aporetic, and by bringing one aspect to light leaves others in the dark. There is no logos of the whole.
I understand the reason why "supernatural" , which I had suggested, is misleading.The wholeness and order of the Cosmos (Plato) now looks to me like panentheism not theism. When you say "there is no logos of the whole" do you mean that nobody can explain Cosmos absolutely but must in all reason do so only doubtingly and partially. If this is what you mean and it's true, the upshot is that The Sun which the philosopher king could see outside of the Cave , i.e. the Form of the Good , was what the philosopher king aspired to , or in other words the philosopher king's faith .
Is faith in the Good ultimate reality and so better than us prisoners' struggling efforts to see good and be good? Or was Plato saying that us prisoners are also and necessarily part of ultimate reality? If not then it looks to me that Plato is undemocratic. Unless Plato is saying that us prisoners can be brought into the light of the Sun.

My last paragraph is muddled. I'll sort it out.
Which are the case among the following:
1. The philosopher king remains the permanent elite among permanent prisoners in the Cave.
2. The prisoners in the Cave are rescued from their ignorance by the philosopher King.
3. Not the philosopher king ,nor the prisoners, nor any former prisoners are able to view the Sun except through the eyes of faith.
4. The Form of the Good can be argued by moderns, especially perhaps by Buddhists, to correlate with inherent predisposition towards fairness as in distributive justice.
