I talked of gravity as an example of a force (or field) that humans have experienced every day without noticing it. (Let me reiterate that noticing that we fall down is not the same as noticing gravity as a force). It needed someone to notice it, think about it and come up with an explanation before we realized that there was something pulling us down. Similarly, bacteria and viruses which we could not notice even though people fell ill regularly.
It needed someone to focus on it certainly, present an hypothesis and produce the evidence to support that hypothesis. if you take bacteria for instance, it needed evidence that such things existed(Antonie Van Leeuwenhoek 1676) and then evidence that particular types of bacteria are related to certain diseases.(Robert Koch, TB, 1882).
This was to show that evidence for something could exist all around us and we might even experience it regularly, but we might not notice or realize what it is.
Of course, but that is a long way from your rather naive and strident idea that 'no one noticed gravity for thousands of years until Newton came along'.
I know these analogies probably make you nervous with the possibility that evidence for spiritual realities might really exist all around but you people may not be noticing. It could be a little disconcerting. But we should be prepared to face such possibilities if we want to understand reality in all its dimensions.
Not at all, except perhaps in your mind. However, if you are really going to make a point about 'spiritual realities' then, as with bacteria above, you need some hard evidence to ground your ideas. So far you have given none, so why on earth should we take such ideas as a universal consciousness or reincarnation particularly seriously?
The best you seem to be able to come up with is the idea that it is an insight, that you can feel it in your bones.
Well, from a very young age I occasionally had powerful feelings that there was no particular overriding purpose to the natural world. This feeling has stayed with me all my life but, as I got older, I realised that simply to have a feeling or an 'insight' wasn't good enough. Simply to have something that you feel in your bones does not make it so. Hence the only way that I would find meaning and purpose in the natural world would have to be evidence of this. I have found none.
And it is at this point you always fall down(figuratively, of course). You seem to be able to provide no real evidence for your subjective beliefs and, when pressed, resort to the idea that you possess some sort of subjective quality which others are blind to. Far from that idea being disconcerting, it's one we could all use from our particular viewpoint if we so wished.
I suspect all this will fall upon deaf ears, although one might hope...
