Can Pugpaws or other experienced mature lots explain to what this means ?

I think you slightly misquoted my saying.

It is

A wise man can learn more from a stupid question than a stupid man can learn from a wise answer.

I think this is one of those saying that you either get or must spend some time reflecting on it before it becomes clear.

Here is another one of my saying that I use at times. It was written to relate directly to some of the questions about the martial arts that are posted on Y/A.

Wisdom comes only after many years of practice and much reflection on what one has learned. Ignorance we are all born with and some never progress beyond it. Still others start out ignorant then build a philosophy around their ignorance convincing them that they are correct in their beliefs. In combat it does not matter what you believe is the correct way. The truth will not be changed. Either you survive, or you don't!

It basically means even if a stupid question is asked it gives you an indication of what level the person is on that is asking it and possibly where they might be coming from in asking it if you are wise or have a wide background and breath of experience concerning what the question is. A stupid person on the other hand will not be able to discern this and that all will be lost on them and they will consider and dismiss it as a stupid question and also the asker as being stupid for asking it probably.

If they were completely dead, there would be no chance of revival. The people who claim to be dead when experiencing NDES have gone into cardiac arrest. There is a small window of minutes after the heart stops that an oxygen-starved brain can still survive. When dying, it shoots of neurons in the areas of the brain responsible for visualization and sometimes auditory perception. It's not hard to put two and two together. NDEs have also occurred in pilots training under high gravitational forces. They pass out and have no risk of death, but report similar experiences -- after the blood drains to the back of their head due to gravitational forces. So that would seem to put a damper in your theory. I find the concept of NDEs exciting. I don't see them as evidence of the supernatural, but as a possible natural explanation for why people may believe that an afterlife exists after death or can be reached by other states of mind. What if some of the texts that describe a white light, sense of calm, or an afterlife are actually the result of isolated experiences due to oxygen starvation? It's very cool to find some of the biological indicators for belief systems. Look at the crosslinks in different religions -- the Native Americans took peyote and pursued "vision quests" to alter their mind so they could supposedly tap into a religious experience, the NT of the Bible describes Jesus fasting and going to the desert for 40 days, which could produce hallucinations or "altered" states. It's interesting. But don't make the mistake of associating NDEs with some sort of afterlife: The brain is still alive, just in its death throes.

I prefer the one, "a fool learns from his own mistakes, a wise man learns from the mistakes of others."

A very simple example/explanation:

(I am guessing English is not your first language)

A wise man thinks = he learns.

A stupid man doesn't think = he doesn't learn.

Good luck!

theres nothing complicated about that.

any philosophy born of ignorance has to be ignorant. all philosophies are ignorant.
