Hands can not cut through steel, but it made the torch that can, hands can not cut paper, but it made the scissors that can, hands can not go through your head, but it made the gun and bullets that can, ever seen a Carrier Ship,? every cannon,every element of that ship were constructed through the manipulations of Hands at work, tool makers make tools with thier hands, they forge molds to make bigger tools, with thier hands, there are nothing in this world that hands didn't manufacture and produced, name one substance in matetials that hands did not participate, feel like a kindergarden teacher,geeez,...

So far, you have not named a single thing that was actually built by human hands. Yes, hands are involved, but your exaggerated grandiose claims are to the effect that hands are somehow perfect tools, which is clearly a stack of bollards.

Hands are only capable of creating simple tools. The amount of stuff humans had to go through to get from our clumsy, stubby, meaty weak hands to any really worthwhile instrument is simply staggering. We had to build an entire civilisation, just to get the materials, the know how, and the can-do to build a half decent hut. From there, the progression of technology upward to space flight has been the ongoing story of building better tools, using worse tools, using even worse tools, using hands.

Hands can not cut through steel, AND they can't make the torch that can, AND they can't make the factory machines that made the torch, AND they can't make the steel components that went into the machines, AND they can't even make the ballpoint pen that drew the plans for any of these steps.

Giving human hands credit for all that we've ever made, just because they can make a fairly workable stone axe and start the ball rolling, is one of the most absurd reductions that it has ever been my bemused pleasure to meet. Just because hands might be neccesary (for now), does not mean that they're actually good tools.

I'd also like to say that I find many of your comments in this thread rather unneccessarily confrontational. You've called us all morons. You've compared us to kindergarten children. You've made a specific attack on me personally, calling me tunnelled. I have absolutely no idea what you mean by that, of course, so it's hard to actually get angry about it, but I would like to recommend, one pinnacle of evolution to the other, that you back the hell down.

Member in doubt, sir my subject has been taken out of context,misrepresented,and redicule, yet I know every criticism are not valid because perpetrators are aware of my points but refuse to concede, there are some remarks that are redundant,'hands have never made this or that' tell me sir, what do they mean by that,? a steel foundry are elements of hard forged special iron facilities, carrying melting iron from place to place has to be feasible , do they mean that hands can't carry molten steel,? it are that frame of mind that confronts my subject,are it rational,? Hands are behind every tech, in our civilization, our very existence are dependant on Hands,if these fact are not realized, it are kindergarden, would you back off,??

Somebody translate that.

It is not that hands are the perfect design for the manipulation of materials. It is that hands are what we've got, so we maximize the usage of them. If humans had 6 tentacles Cjana would be proclaiming that tentacles are the perfect tool.

Cojana, what is your opinion of the human eye? Is it perfect?

HeatherD

Oh, geez, I can't believe this thread.

Cojana, human hands are not the perfect tool, the human brain is the perfect tool. It is our ability to modify, adapt and imagine our world that leads to all the tools you mentioned being built.

Human hands can build simple, clumsy tools like levers and hammers. There are others of course but every tool that humans build requires a simpler tool to be built first.

Evolution didn't bring us the best body, not the best feet, legs, or hands. The hands are a wonderful tool, early hominids had the same hands we have. They were just as able to build simple tools. It wasn't until we came along with our hands and our brains that we were able to design much more complicated tools.

That is what everyone else has been trying to get across, that the human hands are not perfect, that the human brain is the best tool on the planet.

Look, this is really bloody simple:

I cannot take a well tightened hard drive screw out of a computer without using a tool other than my bare hands. This means there is a function that other tools can accomplish that my hands cannot.

The first definition of perfect is:

Lacking nothing essential to the whole; complete of its nature or kind.

My hands are lacking in the area of being a tool capable of removing hard drive screws. Ergo, my hands are not perfect tools.

Done.

Also, let's be frank: I think it are time you did some English learned before you are comparings other to kindergardeners.

Doubting Didymus

I wouldn't mind if you were only incoherent, but the fact that you are also set on being obnoxious, labeling anyone who fails to agree with you kindergarteners, tars your assertions with some very offputting delusions of grandeur. You need to grow some humility. Your comments indicate a lack of understanding of technological and industrial growth, a near-total abscence of understanding of the theory of evolution, and rather a lot of bad ideas about human history. If these fact are not realized, it are kindergarden.

For the most part, what Cojana is saying is muddled and unclear, but I suspect the point he is trying to make is that we would be unable to be at the technological state we are currently in if we did not have hands. Imagine if we had our current level of intellect, but we had the body of, say, a lobster. Even if we could do integral calculus in our lobster heads, we still couldn't do much more than grasp simple sticks and aimlessly wave them around. Build any kind of meaningful tool with lobster claws? fugedaboutit.

That's not to say that human hands are perfect by any means, or that evolution (here or on another planetary system) couldn't come up with an equivalent, or better replacement for our current hands though.

Cojana

member whom intervened in my behalf, thank you sir, for saying what I've been saying all along, you said what I said,but somehow what I said are incoherent even if its the same remarks you made, I'll make my point once more, Hands are the perfect tools,because they can mold,manufacture,and produce any thing the mind can concieve, I understand more then you think about our technical advances,about our civilization, I'm always tuned to the 'science channel,and the discovery channel, marvelous what hands have produced,just marvelous,...
