The Swinburne poem that SRS linked to kind of captures my attitude toward the whole process of *being*. It is at once both serious and tongue-in-cheek humorous.
I studied **BEING** (Sartre, Heidegger, Husserl, Hegel, Whitehead, and several others) formally in several classes many years ago and gradually realized that, as Heidegger said, the question of "Why is there being at all" is fundamental.
   Yet, the only answers are imposed on it BY beings, and they don't agree with each other. You may have read some of my jousting with good ol' Amos about 'meat space' and the eternal nature of something like 'spirit'. Amos was at one time up to his eyebrows in Scientology, but backed away from the awkward stuff L. Ron Hubbard spouted and just kept certain 'feelings' about Metaphysics.

That basic division can be seen in dozens of disputes by professionals...like this one

Humans, being able to pose such questions, usually want answers, and create astoundingly complex answers depending on some subjective need. The most common ones are a form of "God did it!"...without asking "Why was there a God to do it"!

   Science, in its pure form, simply examines all the aspects of 'what is' that it can measure or find evidence of, and thus upsets many of the "God did it" crowd with constantly changing evidence and answers.

So... for me, the Swinburne poem says something in a few lines that I would take hours to say... something like, 'It's interesting to speculate, but I don't NEED ultimate answers.'
   All purported final answers to the 'meaning of Being' are logically flawed, even IF one of them happens to be true.
   My favorite logical explanation is "the Explosion Principle"... which in itself provides no final answer, but merely is a way of saying that IF your premises can lead to 2 or more contradictory conclusions, at least one must be false.. and maybe all of them.

Yes, I realize that "The importance of being while doing" intends to say more subtle things than my ramblings, but I contend that we all MUST 'be while we do' and it is just a matter of .... (coining a phrase)... what FLAVOR of being we choose.
Gotta stop now... I have way too much uncomfortable 'doing' on my plate this year....
