Author | Topic: Can Natural Selection Produce Intelligent Design? | |||||||||||||||||||||||||||

this thread seems to be headed in the direction already taken by
EvC Forum: Is there any indication of increased intellegence over time within the Human species? and before that by the subthread on "bones of contention" http://EvC Forum: Bones of Contentions. focusing on what intelligence is rather than focussing on ID. can we assume intelligent design is involved because intelligence is evident in many species? do we have to? I would say people are free to make that assumption, but it is not necessary. The next question is what that intelligent design process consists of, and whether anything beyond normal evolutionary mechanisms are required. Enjoy.

And a 2-input NAND gate must not be able to output a logic 0 iff both inputs are high, since the individual components can't perform that function. http://www.opamp-electronics.com/...images/digital/04094.png Oh wait, it does.The circuit evaluates A+B. (1,1) has a value of 0. (1,0) has a value of 1. (0,1) has a value of 1. (0,0) has a value of 1. I do a similar thing when I evaluate a logical argument, except I use a multiple-input gate, and stick an inverter on the output to make it an AND gate. Iff the inference is valid, AND all the premises are true, the conclusion is true. If any other combination, the conclusion is at an indeterminate truth value. The fact that an individual neuron can't perform this function doesn't mean that a group of them can't be hooked up to do it.
nwr writes: I'm looking at judgement as the outcome of a process, rather than the decision of a conscious agent. I suppose this comes from my interest in artificial intelligence and cognitive science. I am wanting to be able to consider intelligence as arising from a community of simple judging processes. Well yes, but the problem here is that you have no hardware. There's no judgment that one variant is a better fit to its environment than another; it simply is that one variant is better fit to its environment than another.

Since you are replying to me, I guess I should comment

No, I don't see that at all. My posts have been related to the idea that intelligence can and does arise naturally. And if simple forms of intelligence can arise naturally, then it is surely possible that natural selection can produce more complex intelligence.EvC Forum: Is there any indication of increased intellegence over time within the Human species? and before that by the subthread on "bones of contention" http://EvC Forum: Bones of Contentions. -->EvC Forum: Bones of Contentions. focusing on what intelligence is rather than focussing on ID. If the moderators think I am taking this in the wrong direction, then I guess I will have to stop posting and see in what direction others want to take it.
can we assume intelligent design is involved because intelligence is evident in many species?
My understanding of the OP is that humans are intelligent designers, and that if humans are the result of evolution, then intelligent design results from evolution. As I see it, the OP was wanting a discussion of whether that is possible. It seems that you have a different understanding of what was being asked by the OP.

I don't agree with that. DominionSeraph was questioning me with respect to my use of "judgement". In the case of the NAND gate, I would not say that there is any judgement. A NAND gate is just a simple deterministic device.
I do a similar thing when I evaluate a logical argument, except I use a multiple-input gate, and stick an inverter on the output to make it an AND gate.
Likewise, I don't see any judgement in a multiple input gate, nor in the formal analysis of a logical argument. When we ordinarily use logic in our reasoning, we don't restrict ourselves to a formal analysis. We also evaluate the assumed premises, and that is where I see us using judgement.
Iff the inference is valid, AND all the premises are true, the conclusion is true. If any other combination, the conclusion is at an indeterminate truth value.
Sure. Except for "all the premises are true", this is completely mechanical and deterministic. No judgement is required, and no intelligence is required. The hard part is with "all the premises are true". When this has to do with real world matters, as distinct from formal logic propositions, the question of whether the premises are true can require considerable intelligence and judgement. But that judgement is outside what any NAND gate or other logic circuit can achieve.
The fact that an individual neuron can't perform this function doesn't mean that a group of them can't be hooked up to do it.
You seem to see intelligence in a NAND gate, and want to use that to prove that there can be intelligence in a neuron. By contrast, I see intelligence in a neuron such as we shall never be able to replicate with NAND gates alone.

lmrenault writes: But many of us would argue that this very sophisticated intelligent designer, unique on earth’s landscape, has been produced by the evolutionary process that Darwin describes. Can we make sense of this? Can such a super creation as Hs — an intelligent designer - be the product of mutation and natural selection where there is no intelligent design input? I don't see why a trial-and-error process couldn't come up with a trial-and-error brain. Life, using a process that works really well at finding things that work really well, simply found its own process.Seems to me that a configurable brain wouldn't be limited to literalty. An input could be segmented; the segments could then be shunted off along different paths, and then combined with other segments from other inputs to form concepts that aren't the result of a singular input. Thus, 'imagination'.

nwr, msg 18 writes: My understanding of the OP is that humans are intelligent designers, and that if humans are the result of evolution, then intelligent design results from evolution. No, I hadn't seen it that way. The take I had was that evolution of "Hs" intelligence was of singular significance and not possible without ID help. But I am happy to move to this interpretation. I had just noticed that we seem to have three threads that are essentially discussing the same thing: the evolution of intelligence (and what we mean by intelligence), and that consolodation might make it more instructive. {{fixed typo}} This message has been edited by RAZD, 08*14*2005 07:21 PM we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

Neither a NAND gate nor a multiple input logic gate will come up with an indeterminate truth value. If you are doing what a NAND gate could do, perhaps you are using some judgement. But the use of judgement is superfluous, for the decision can be reached mechanically, as by a NAND gate. The conclusion is completely determined by the input, and anybody else could, and normally would, reach the identical conclusion. Your judgement is not needed. If, however, you are doing something where there could be an indeterminate truth result, then you are doing something other than logic, and you are exercising judgement.
In daily life, we seem to use a subconscious process that has access to a shitload of data. It might just be a difference engine.
If the conclusion could be at an indeterminate truth value, then you are not doing what NAND gates can do, and you are not just applying simple logic. In Message 20, DominionSeraph said "I don't see why a trial-and-error process couldn't come up with a trial-and-error brain." That's a good example of what I am suggesting. In many cases, a NAND gate cannot tell you whether the result of the trial was an error. Whether the result was an error is an empirical judgement, but logic is abstract, so does not make empirical judgements.
The input of one gate can be the output of another.
This doesn't alter the fact that the gate will produce a determinate truth value.

It kinda fits your response to me on this a few weeks back.
Because of the abundance of complexity, the evidence agaist ID is apparent. Intellegence cannot produce complexity. Intellegence is restrained within the world of complexity. Complexity is a by-product of evolution which is a bi-product of space/time, and energy expenditure from the Big Bang. Intellegence can produce design, and the design may resemble complexity on a very superficial level. A microprocessor attempts to resemble complexity but only to the degree that a cloud can momentarily resemble a car or a plane. True complexity as in the human brain can only be achieved through mutation, chance and selection over the onward march of time. To suggest that the incredible complexity of our natural world could be the result of intellegence and design is like saying that you could carve Mt. Rushmore with a toy squirt gun, a gallon of water and a free afternoon.

His choices are self-directed by whim or by reason, yet if he is he product of natural selection where there is no free will, he seems to have broken away from the process. This is what makes him an intelligent designer. So if he is designed he has free will to do whatever he wants but if he is not designed he doesn't? How does his not being designed negate "His choices are self-directed by whim or by reason" in this case? What prevents it? Seems to me you have it backwards. If he is designed he is {restrained\restricted\constrained} by the box (world) built around him and cannot escape it. He is a monkey in a guilded cage that just thinks he has free will.

nwr writes: Your judgement is not needed. It is if I want to do anything with the conclusion. If I don't have that output, I'm right where I started.
nwr writes: Whether the result was an error is an empirical judgement, but logic is abstract, so does not make empirical judgements. That's fine, though. Incoming sensory data is simply flagged as true, so that doesn't have to be an output of the circuit. So, now we have a known good to check the output of other circuits against.

Check out Bowerbird Nesting habits. They fit all of your criteria. They begin with an idea, the create something that exhibits a unique plan, they show selection in choosing the materials by shape or size of color. Well I guess I'll have to put the Bowerbird along side Hs as an intelligent designer ;-) Obviously, we see elements of intelligence in many critters, but I have to maintain that man's demonstration of creative imagination, independent choice, will power, and artistic expression sets him uniquely apart. And it's interesting that these characteristics are not equally shared. Every Bowerbird makes a nest, but not every man has the ability or inclination (choice) to design and build a house. The expression of design is highly variable.

But the Bowerbird does more than just build a nest. They build unique and individual nests.
Now let's consider our cousins the primates.
