Hey now! I don't like this! :p
You're attacking the basics with which we hope to come to a general truth, which we all want to do here. The premise being that by rational thought uttered in words we can come to new and more accurate conclusions. Now, I was kidding, you're not attacking the basics of course. We're here to find both how and why.
Because they are interlinked and in some way, imo, the same thing. But if you want to differentiate their meaning, fine. Let's get back to the basics of how we're doing what and why(ok, not why, but this was a how and why discussion so I felt obliged to say why

. So, you feel why is a potentially more import question than how.
Fine, let's see what other basic (grammatically speaking) questions we have. A list: Why, how, when, where, who and what. Ok, so why is when not important? Because time may not exist? Because it's relative? Excluding therefor on grammatical basis? Why(hihi) can't we do the same with why then? Which also refers to reason, just as much if not more(or less, WHATEVER. I DON'T KNOW) then how.
Next in line(yes, I'm not one to even obey my own order. I'm one chaotic mind): Who? Ok, we can't say, who does it work. But we can go over to the thread about consciousness or about god. Who being the question of entity. Perhaps this holds all answers. Perhaps not. Perhaps it's a part of the bigger picture (perhaps it also includes the full understanding when one makes an analogy).
What? I think this is the question we're all really asking ourselves. Unless you just look at what as matter and energy (and so on? If you must use other scientific concepts to explain everything)
Where? Time-Space continuum. Space problem as When. Want me to use hard words to make my point? I'm sure somebody will come along shortly with terms such as flux. The point it, they are dependant when used as concepts to measure our reality on a grander scale.
I'll stop right here for now, waiting for you all to correct and/or stop me

(Spellcheck didn't find anything and I don't want to reread everything, please contact me if I made some basic mistakes regarding the english language)
