It's not that aging, illness and death would render death as the greatest fear; it's that they render life as it is usually lived, meaningless.
That is not fair. If you believe you have a winning argument, then, by all means, present it!
Was it pointless for trees to sprout, grow and eventually whither away simply because they did in fact eventually whither away? Was it pointless for stars to go supernova in cases where the aftermath didn't result in a planet that was capable of supporting some sort of intelligent life? Is a black hole pointless? What about a rock on Venus? A comet in an elongated elliptical orbit around some distant star?
As far as I am concerned, the fabric of the entire universe is sacred in a way, as are all of it's many (and perhaps even infinite number of) manifestations, because it's substance is the substance of life itself. We're quite literally made out of it. In fact in some ways, it's like a mother.
I realize that not everyone views it with the same sort of wonder and reverence that I do, but it's really not such a stretch. It's here, it gives birth to conscious life, and we are currently a part of that. And ultimately, I think it's terribly self-important of us to suggest that it all becomes meaningless the moment we're no longer around in our current form, especially when it looks like it's going to be capable of supporting life for at least another 100 trillion years, and will have hundreds of billions of stars in hundreds of billions of galaxies in which to do it, and that's assuming that it's not spatially
infinite, which it very well could be. But even more than that, it seems pretty obvious (to me, at least, primarily for what I consider to be sound philosophical reasons) that the fundamental fabric of reality is actually eternal, and it's manifestations possibly cyclical in some way. If true, it would essentially mean that there is infinite possibility (in accordance with the nature of 'nature' itself, that is). In other words, any quality that
can manifest,
will manifest, and a lot more than just once. In fact in the fullness of eternity (if that makes sense), everything that can be, is, has been, and will be again. It's a wholly complete and unending expression. Some pantheists call it God. I call it the universe. Existence itself.
Of course, I don't know for a fact that
all of that is a true account of the ways things are, but it's what makes the most sense to me when I let my thoughts roam free as part of my own ongoing 'spiritual' journey. And yes, I do consider myself deeply spiritual, albeit not in the traditionally theistic sort of way.
So there you go. It's only a summary, and a lot of it is somewhat tentative, but it's me.
