I don't know why this simple idea is so difficult to understand. A microscope enhances certain perceptions, but it also has its limitations. It can't be used to look at the stars.
What I am talking about is that certain mindsets and mental limitations can prevent us from 'seeing' or understanding certain phenomena. We need to change our perceptions if we want to access certain ideas.
Neither a microscope nor a telescope enhance or develop the idea any spiritual reality at all. They are both concerned with and enhance our knowledge of the natural world. They both have their limitations. That is why your attempt to contrast the two is such a poor analogy.
What you seem to be concerned with is the idea that we are a victim of a certain mindset which limits us from being spiritualists(in the philosophical sense). That is a fair point and one that could be true but, alternatively, one which fails to deal with the very real proposition that some of us have not been curtailed by such a mindset but have come to our views in full knowledge and realization of the mindset which accepts the reality of a spiritual world. It is not that we have necessarily utterly rejected that view but find little to commend it either from a rational and evidential position, but, also, and speaking purely for myself here, from an emotional and experiential position. That is not to say such a spiritual reality does not exist, but surely you must accept that simply suggesting that such a thing exists if only we had the perception to see it, is fraught with problems. What if your perceptions are simply a result of your mindset? what if they are plain wrong? How can we tell? You dismiss the idea of evidence yet you put nothing in its place, so how can we judge? And then you simply label us as 'adolescents' because we do not agree with what you say. Assuming that you wish people to be sympathetic to your point of view I would suggest that that is not the way to 'win friends and influence people'.
Finally you speak of 'understanding certain phenomena'. This may or may not be true, but I have to say your understanding of evolutionary theory leaves a lot to be desired, and your emphasis on the importance and significance of NDEs is at the very least contested.
Perhaps, if you desire humility in others, then it would be a wise approach to use a little humilty also. And you could start by trying to understand why so many people on this forum have difficulty, not in understanding your ideas, but in accepting them.
