Yes, you said having eyes is better than not having eyes. I agree. It wasn't
entirely clear the way you wrote it, but I figured it out. Andrew Hamilton misunderstood.

Now, can you answer this very simple question:

Is having eyes with blind spots better or worse than having the same eyes without
them?

That would depend on what the blind spot does for us, or does not
do for us. For all I know it keeps the eye functioning over time, not
knowing the ends and outs of what would our eyes be like without the
blind spot it is difficult to say. You can of course act like you know
and say it is flawed, I'm not prepared to go there.

I'm going to go with "eyes without blind spots are [b]better than eyes with blind spots", as blind-spot free eye will gather more information than the same eye with a blind spot. Considering the amount of information processing that goes on right now when processing vision from our blind-spotted eyes, the amount of extra information would have a negligible ...[text shortened]... t would have a measurable positive impact on our visual acuity.

Care to comment, KellyJay?[/b]
I did in another post, if I was forced without knowing the details of
what would occur over time without that blind spot I'd lean towards
agreeing with you.

What reason would you posit that a blind spot helps the eye function over
time? Why do squids' eyes continue to work without difficulty without blind
spots?

Do you have any justification for having this belief?

I have not spend any time thinking about your blind spot concern, as
I pointed out to you earlier since it could have gotten there by
degrading over time that is one way, or another possiblity could also
be it is there by design. Design would means it is there for a good
reason, not sure what reason would justify it, maybe not having it
would harm other body parts due to the way they are exposed to the
light, do not know. Squids again are not living in the world the same
way we are why not worry about birds and flys, thier eyes help them
how they live too, does that mean anthing to you?

Thanks for the bump of the post too. It is hard to keep track of many
of these I'm in.

Nope, I'll agree there is a blind spot that we seem to get along rather
nicely with.

The difference is important to you but not the argument. The logical argument for any god/God is the same.

If you wish to present an argument for a deity it will be the same argument.

Using a capital G will not make your argument better.
Not saying using a G makes my argument better, but it does show who
we are talking about a little clearer, and as I pointed out before, for
me it is very important. It may not be important to you, but if you did
express some term was near and dear to your heart I would out of
respect for you attempt to give it the respect you ask for.

I've addressed the 'degrading' argument. The cephalopod eye is no more or less complicated
than the mammalian eye. One has the nerve fibers on one side of the retina, the other has it
on the other side. The entropy argument doesn't follow.

Design would means it is there for a good
reason, not sure what reason would justify it, maybe not having it
would harm other body parts due to the way they are exposed to the
light, do not know.


So, are you saying you don't actually have a good reason to believe that the blind spot has a
beneficial purpose? Because it sounds like what you're saying is 'There might be a good reason,
therefore it's reasonable to believe it.'

What I do know is this: Blind spots obscure vision, and having obscured vision is not good.

So, to be clear, is what you are saying, 'Since there might be some obscure good reason which
I can't imagine nor defend for having blind spots, having them is good?'

…what is it you wanted me to address? ..….

the 5th post from the bottom of page 20 of this thread -here is a reminder but I have replaced “god” with “God” in it just so that you now don’t use that to sidetrack from my questions:

The fact that we currently cannot deign and make living things is irrelevant to
the issue because, the fact remains, if we COULD deign and make living things, we would at
Least do so intelligently and we certainly wouldn’t put in obvious and stupid design flaws in things.

Your claim is that “God” designed living things and this “God” has a huge amount of
intelligence such that he doesn’t make mistakes and does everything “intelligently“ -yes?
-if so, then the logical problem with that which we are all trying to make you understand is
that IF there is such a “God” and IF he CAN and DID design and make living things, why on earth
would he make designs with obvious and stupid design flaws? that wouldn’t be logically consistent
with the hypotheses that he does everything “intelligently” and makes no mistakes -yes?
