I think if God wrote down all nuances of every situation and of every point of life, we wouldn't have enough room on this world to hold it all.
So, who is there to tell the baby what to do, Ken? Who is there to inform the baby to chew a certain number of times each bite of food that enters its mouth? This IS pertinent to the discussion here... since you indicated that human understanding should necessarily augment the "intelligent design" of the human body. Who among the "designers" seems to have cared about the babies and how they might handle their solid foods in this respect, Ken?
What I believe is pertinent, is that how one eats or treats his/her body has nothing to do with intelligent design, which was the posters point. It has to do with how one eats and treats his/her own body.
I believe the original poster's point was that, were the body designed differently (perhaps a little more intelligently?) we wouldn't have a concern like a piece of food obstructing our airway and potentially causing our demise. Your point about "being ignorant of the number of times one should chew" does not, at all, speak to the supposed flaw in the
design. All it does is pass the responsibility on from the designer onto the one needing to utilize the design. And believe me, I understand why you have to do this... because the "designer" cannot, in any way, speak for himself/herself on the matter. I just (again) hope that you also understand why you have to do this on his/her behalf.
But just think of it this way... if I were to be given a bicycle that had no handle bars, and I learned to ride it that way, by balancing my weight to one or the other side to affect wide turns, and keep myself level otherwise, if I thought about it and realized that if I could control the front tire in some way I would have a much easier time of the whole ordeal, and then I were able to install handle bars and then ride that way (subjectively a much better experience) might I not look back on that earlier design as somewhat inferior? Perhaps even wonder why someone didn't think of this type of thing before? And all those times people would have crashed their initial bikes trying to learn to keep balance and control with their weight - we could, I suppose, blame all of those crashes on the user of the bike. But then, with the advent of handle bars, wouldn't some of those people look back and lament that if they only had the handle bars to begin with, then there wouldn't have been all that crashing and hurting happening all over the world? Is that such a crazy thought for a person to have in that situation? Not necessarily "blaming" the designer... but realizing that the design isn't "the best" it could be, and that if the "designer" is supposedly so very, very intelligent and amazing at his/her job, wouldn't one also then easily wonder why they, themselves, could think of a modification that would make it better? Is that so outlandish?
