... Why not? Neural networks extract universals from particulars.
--------------------------------------------------------------------------------
Of course they do. That doesn't even begin to address the requirement that your worldview account for the necessary precondition for this ability.
What? Organic chemistry? Electrochemical reactions?
What about these things need to be justified. They exist. They are there for everybody to see for themselves.
--------------------------------------------------------------------------------
That's what they do and how they work. You and I and everybody we know is equipped with a device that generalizes from particular perceptual input. It's called a brain.
--------------------------------------------------------------------------------
That's not an answer to the question, Mr. Ben.

I'm listening.
Generalizations of and ideals are products of how neural networks function. They reduce specific patterns to symbolic representations through information convolution. This is a physical mechanical process. That's about all there is it say about it.
Jim wrote: Dualists have tried, but the result is just as irrational as the materialist view. Atheists who simply pretend that there isn't a problem between universals and particulars succeed only in convincing me that they haven't reflected adequately on the problem (or they're being disingenuous).

Nonsense. Metaphysics is not the proper realm to discuss such matters.. as it doesn't take into account what particulars and universals really ARE.
--------------------------------------------------------------------------------
Fine. We'll use whatever realm you prefer. Please state it and give an account for what particulars and universals are in terms of whatever realm you choose.
Particulars are the specific perceptual signals your eyes, ears and other sensory equipment generate.. presumably from the outside world. The general is the end result of the convolution process where these perceptual signals are convolved into useful symbolic models by the brain's neural processing.
There is nothing about this process that is metaphysical, or magical. It is a physical process which is well understood, a product of how large scale neural networks like the brain function.
Did you mean to say that the fundamentals of information theory are based on the concrete descriptions? No? How do you justify either one?
They exist according to my perception, and they work because I percieve that they do.
Are you saying that you believe they work because God exists, and that you believe he exists because you made him up? I don't think making up imaginary people to explain things is very reasonable.
Keep to what you see, experience, and know directly. Do not invent explanations for things.
--------------------------------------------------------------------------------
Archaic metaphysical terms only cloud the issue. We can discuss these matters using these old fashioned terms, but what we're really talking about are physical processes that take place in real brains.
--------------------------------------------------------------------------------
Really? Is modus ponens a brain state?
Modus ponens and brain states which model it are both products of temporal causality in this universe. Were temporal causality not to be consistent, or predictable, neither would exist.
We can concieve of universes with radically different temporal and causal relationships. In these universes, the logic of modus ponens works differently. For example, univeres where causes lead to probable effects instead of definite effects do not have modus ponens in its standard form. I would expect any "brain" in such a universe would work differently as a result. Universes which have non-linear time, looping time, network time, or cellular time also result in different forms of logic.
So modus ponens and the brain stem from the same source, the physical rules of the universe. Logic is not meaningfull except in its relationship to the universe it exists in.
Who gives a rats ear what the Bible says.
You do ... enough to be hostile against it. If I were to have quoted Daniel Dennet or Fredrick Engels or Sigmund Freud, I highly doubt you would have responded so defensively.
Who gives a rats ear what Engels, Frued, or Dennet say. This is a matter of reason and argument. No source is allowed to define the answer by fiat.
You just moved from a universal requirement to your own contingent experience. How do you know there is no solid evidence for God? Have you looked everywhere? Do you even know what your looking for? Can you justify the standards of evidence that you'll accept as valid?
All of us must make a descision as to when the evidence, or lack of it, is sufficient to justify a conclusion.
I do not believe in unicorns, I do not believe in fairies, and I do not believe in God. All of these entities I classify in the same category.. things which people have claimed to have existed, but for which there is no evidence.
Could they really exist? I suppose there is an off chance that fairies are real and I am mistaken. However, until somebody presents me with evidence which confirms their existence, I will continue to believe that they do not.
--------------------------------------------------------------------------------
There is no solid evidence of any God beyond the subjective claims of various believers (most of which are contradictory).. therefore the atheist view is true.
--------------------------------------------------------------------------------
Wow. Do you realize the horrible non sequitur you've just committed? Sloppy, Mr. Ben. Way sloppy.
Yes.. the athiest view is "solidly justified". We don't know for sure if it's true or not. But it has the advantage of not being based on the type of subjective storymaking and fantasy that typically are the source of so much nonsense.
Again.. who gives a rats eye what the Bible says. Richard Dawkins says that the onus is on you, and so does Bertrand Russell.. do you care what these people say?
Yes, I do. I own their books. I find it interesting and useful to consider the views of others, to weigh them against my own, to assess whether there are any insights from their philosophical outlooks that would be of benefit to me. Why the hostility, Mr. Ben?
I don't cotton to complete nonsense. When someone tells me "The Bible says God is true.. therefore it is up to you to prove the Bible false." I respond "Who cares what the Bible says???"
If I told you the "Necrinomicon" states that the many tentacled God Yog Sogoth exists and will devour the world soon.. and it's up to you to prove this is not the case.. how would you respond? Do you really take anything written by a Mad Arab (or pulp horror writer of the 30's) seriously?
The existence of any entity is proven by positive evidence FOR its existence, not evidence for its NON existence.
Who here is providing evidence for God's NON existence? As to positive evidence, what sort of evidence are you looking for?
Well, a being who could move a mountain, raise people from the dead, move planets, create the odd galaxy or two.. etc. Can you produce such a being and have him demonstrate his abilties for us?
If we were to assume that everything that might exist actually "did" exist, then practically everything we could think of would have to exist. This would include green unicorns, great space goats, etc. After all you don't know for sure that there are no leprechauns or fairies.
Are you trying to prove the existence of these? I'm not. So how are they relevant?
Because they illustrate the pointlessness of assuming that things which are not in evidence must necessarily exist. God has no evidence for his existence, fairies have no evidence for their existence, leprechauns have no evidence for their existence. Then why must God be proven "not" to exist when these other fantastic things are merely assumed not to?
Again.. if we fairly use the same rules of evidence you suggest for god and apply them to every entity for which there is no evidence, we must therefor assume that "everything" that offers no evidence must necessarily exist... fairies, leprechauns, etc. This is unreasonable.
Unless evidence for God can be offered, it is reasonable to assume that he is as real as a fairy or a leprechaun.

I see a post in front of me.. I don't duck.. I bump my head. The next day I see the post again.. I bump my head again. On the third day, I make the inference that the post I see in front of me is associated with the pain in my head. I decide to test this hypothesis by ducking. I no longer hurt my head.
--------------------------------------------------------------------------------
Did you test your vision, too? How about the pain you think you felt-- have you tested that, too?
Yes, I feel the pain. Direct perception is a-priori real.
How do you know if your motor neurons are properly excreting the needed acetylcholine to your axon endplates?
It doesn't matter. The perception is there regardless of what produces it. Direct perception is a-priori.
And ifit is not my neurons, it is something else. I only assume that it is produced by neurons because I also perceive the existence of brains, neurons, the physical laws, and the nature and properties of neural networks.
How about the reasoning faculties that seemed a bit slow on the uptake. Maybe those are not very reliable. How would you go about testing them?
If my models of reality are inconsistent with reality, I would expect to be consistently suprised by constant contradiction from reality.
So where precisely is the "christian worldview" in this simple description of inference based on experience?
--------------------------------------------------------------------------------
The Christian worldview gives you a foundation for knowing that your actual experience comports with reality, that your senses are generally reliable, that you're reasoning faculties treat accurately of the input, and that you're not dreaming.
But I am dreaming.. the christian worldview.. OOOPS! Your argument is demolished. Sorry.
The fact is it really doesn't matter if you're dreaming. If you were dreaming a dream of a world that was in all ways indistinguishable from the real world.. it makes no difference. The "difference" is precisely and absolutely meaningless from an empirical standpoint. In other words, there is no difference.
Otherwise, you are, at best, guessing and hoping that you're not deceived by your senses, duped by your own faulty reasoning processes, or stuck in a dreamstate that you can neither verify nor escape.
Decieved by my senses. Since reality IS my senses.. that is not logically possible. You can't be deceived by what defines reality in the first place.
It bridges the gap between your contingent, changing experiences and the universal invariant laws that describe them (such as induction). Sentences make sense. Morality makes sense. Science makes sense. Mathematics makes sense.
Actually, these all make sense only because Santa Claus exists and made them so. You're notion of a Christian God only makes sense because you are borrowing from my Santa Claus viewpoint. If you were not, how could you know for sure that your believe in a Christian God was justified?
Santa Claus is the source of all logic. All epistemological and ontological questions are answered by fiat because Santa Claus exists. If you have a question about ontology, it is answered by Santa Claus. All you have to do is simply first believe in Santa Claus for it to all make sense.
On the atheist worldview, nothing makes sense, everything is fraught with question-begging, faith based, blind assumptions.
Yes, but not so with Santa Claus. That goodness he exists.. or we would never be able to think.
Not in the least. The Muslim god is posited as a monistic unitarian being. Such a being could not bridge the gap between the contingent and the universal, for all would be one by such a god; there would be no change, no particulars, no comprehensibility in the universe.
No, not that conception of the muslim God.. the one in which he answers all epistemological questions.
But you are forgetting the great three headed green god of Reptelon 7 as well. He not only bridges the gap between contingent and universal.. but also makes julian fries and comes with a 30 day money back guarantee. It is obvious that this is the real God, since by deciding he exists arbitrarily, we get to declare even more epistemological and ontological questions closed by fiat. In fact, the green God of reptelon 7 has declared that he knows the answer to the NP hard problem as well, and the largest prime number. It makes me feel all warm and fuzzy to know that there is an imaginary being that can be the source of such imaginary certainty and imaginary knowledge as my ravenous great green God.
You're not a very careful thinker, Mr. Ben. Of course it doesn't matter in the event itself. We're discussing not how people react based on their various worldviews, but which worldview can cogently make sense of the shared experiences. Please don't force me to type "duh."
Any of them can make sense of it. It's very simple. Duck when you see the post or you'll get a nasty bump.
--------------------------------------------------------------------------------
The truth is that brains evolved to recognize these sorts of causal patterns, ...
--------------------------------------------------------------------------------
When did you witness this "truth"?
Alright.. the physical evidence strongly supports the hypothesis that... is that better?
... and mechanisms that detect them and direct the organism to respond in such a way as to survive more effectively are the results.
I'm curious: why is it, on your view, that countless creatures survive just fine without the sophisticated logical faculties that humans possess?
They are not large bipedal omnivores who must scavenge the sahvannahs for food. Some of them do just fine growing on rocks in the sun.
It's called ecological niches. The solutions to the problems of surivival are all different depending on where a species finds itself, and what it has to work with.
... Logic and reason are names for mechanical systems in the brain which take raw information in,
--------------------------------------------------------------------------------
Have you witnessed these mechanical systems? Can you read a PET scan and distinguish between modus ponens and a syllogism?
Yes, actually we can do that in simulation. We can actually trace the inferences of the visual system down through multiple layers. Edge detection, gradient detection, motion tracking, etc. We also have the evidence from accident studies which disable very specific parts of cognitive function. Oddly enough, some people with epilepsy seem to be prone to extreme spiritual experiences. What does this say about belief in God?
... and turn it into activities that increase the probability that the organism will reproduce and pass on the same behaviors.
Too bad all the other creatures in the world died off because they didn't evolve these "mechanical systems." Wait a second ... they didn't die off? Hmm. How are they surviving without this necessary ability?
Brains seem to be quite useful. A large number of organisms on the planet have them.
Wait.. not all of them have them. That must mean they aren't useful at all!
Are you a hard determinist, Mr. Ben?
I am not sure that physical reality is deteministic, but it makes little difference if it is. What we see as free will remains basically unchanged.
