Well, since you can't or you won't show the elements in any atheistic cosmology that get you to independence and knowledge, and since you are now leaving, perhaps someone else here can do it. Would anyone like to help Merlin out here?

Also, simply because the brain produces consciousness as "matter in motion" doesn't mean that the brain had to have some designer or antecedent cause.  Is it not entirely possible that a function of brain matter is to produce knowledge independently? That the brain matter evolved to form independent knowledge?

Think of this: what if human brain tissue evolved to make choice? That is, to break away from the determinism that rules the roost with lesser animal?

Posted again, since it was not answered the first time.

I am not understanding what's being asked here.

You seem to be asking how knowledge is possible absence god...because knowledge must have some element of independence from determinism?

OK, how about human choice being the necessary ingredient needed from an atheist to posit knowledge?

Our human brains evolved to allow us choice, and not to be guided like planets along their routes or rocks down a hill.  That is, thought is unique to the universe, but not necessarily driven by the Sky Fairy.

Does that count?

Steven, If deterministic materialism is true, nothing is produced, including consciousness! Matter is simply rearranged. According to cosmological naturalism, matter in motion is all there is and that motion is determined by the laws of nature.

We don't need to discuss a designer at this point because all atheistic cosmologies defeat themselves, including naturalism. The fact that all atheistic cosmologies fail, leading to the necessary conclusion that God must exist, is just an extra added attraction. Your cosmology falls all by itself.

Since there are no uncaused events in naturalism, all events have antecedent causes.

Think of this: what if human brain tissue evolved to make choice? That is, to break away from the determinism that rules the roost with lesser animal?
I am not quite sure what you are saying with this. Are you suggesting that the brain tissue is no longer matter in motion? Are you suggesting that it no longer has to follow the laws of nature that all other matter in motion must follow? What kind of scientific test could you perform that would differentiate this brain matter from other brain matter or just other matter in general?

Actually, I am asking how knowledge is possible given any atheistic cosmology? What elements in those cosmologies allow for independent thought? My assertion is that not only do the elements of all atheistic cosmologies lack the positive elements that allow for knowledge, they contain the negative elements that deny the possibility of knowledge. In other words, in any atheistic cosmology is true, there can be no knowledge. Consequently, if knowledge does exist, then all atheistic cosmologies are false.

OK, how about human choice being the necessary ingredient needed from an atheist to posit knowledge?


Have humans always existed? No? Then you still have the problem of how matter in motion, which is necessarily determined, changed to something independent from necessary determinism. If matter in motion is all that exists, then matter in motion is all that exists.

Well, matter in motion takes many different forms -- e.g., animal life, which involves properties such as consciousness and knowledge. Consciousness and knowledge are not incompatible with matter in motion, but are properties of matter in motion, inasmuch as they are attributes of certain kinds of living organisms. Neither consciousness nor knowledge can exist without a material basis in reality.

You keep saying that in this thread and on other threads, but you never show how you get from matter in motion is all that exists to something independent of matter in motion acting according to the laws of nature.

Perhaps, you and I meant something different by "matter in motion." You evidently meant inanimate matter. What I meant by "matter in motion" is simply material entities that act according to their natures. In that respect, animals and human beings are "matter in motion." If we use your definition, then I do not agree that all that exists is "matter in motion," because not all that exists is inanimate matter. Living organisms are also a part of nature. Material existence can take many different forms besides inanimate matter, viz., plant life, non-rational animals and man. All these are forms of material existence.

The non-rational animals, which evolved from lower forms of (plant) life, acquired the attribute of awareness. which plant life does not possess. Man, who evolved from more primitive forms of animal life, acquired the attribute of rationality, which the lower animals do not possess. For those organisms that possess it (animals and man), consciousness provides a survival advantage by enabling them to respond to their environment in a way that plants cannot. Similarly, rationality (conceptual knowledge) enables man to respond to his environment in a way that the lower animals cannot. Consciousness and rationality evolved through natural selection, because they conferred a survival advantage.

The evidence for natural selection as the origin of species is overwhelming. Why assume that consciousness, rationality or knowledge must have a super-natural origin in the form of a non-material consciousness, especially when consciousness, rationality and, therefore, knowledge depend on material organs such as a brain, nervous system and physical senses. Because consciousness is impossible without a material form, a non-material (i.e., divine) consciousness cannot be the origin of knowledge. Evolution from natural selection is the only reasonable explanation.

I agree with much of what you've said here.  What I do not accept is the idea that "rationality evolved", since that is an inaccurate statement.  You ought to have said that the cognitive faculties associated with rational thought evolved.  Rational thought emerges as a higher mental ability in tandem with the developing biological organism. 

Moreover, it is a very blatant misrepresentation of evolution to say that "consciousness and rationality evolved...because they conferred a survival advantage."   

The first human (homo sapiens) appeared on the scene immediately after the species which preceded him/her.   This is equally the case for all new species, as all new species are formed via 'random' genetic mutation(s) during the reproductive processes in which genetic material is combined and inherited. 

Natural selection is a phenomenon associated with populations, not with individuals.  Individuals are the real catalysts for evolution insofar as they inherit new genetic traits randomly and then proceed to either reproduce more or less of their own kind according to their survival advantages. 

So, scientifically speaking, human consciousness and rationality--which arose in tandem with the arrival of the first man-- is a product of 'random' genetic mutation, not a function of survival advantage(s).

Non-material consciousness is not necessarily supernatural.  Philosophers of mind like David Chalmers and Thomas Nagel embrace a naturalistic conception of mind and are also property dualists--believing that the mind is irreducible to the material.

Of course, of course. By "rationality," I meant rational faculty.

Yes, this is what I meant. Pardon my loose language, and thank you for the more precise explanation.
So, scientifically speaking, human consciousness and rationality--which arose in tandem with the arrival of the first man-- is a product of 'random' genetic mutation, not a function of survival advantage(s).
Right, but, as you correctly point out, its perpetuation and proliferation are a function of its survival value.

I wrote, "The evidence for natural selection as the origin of species is overwhelming. Why assume that consciousness, rationality or knowledge must have a super-natural origin in the form of a non-material consciousness, especially when consciousness, rationality and, therefore, knowledge depend on material organs such as a brain, nervous system and physical senses."
Non-material consciousness is not necessarily supernatural. Philosophers of mind like David Chalmers and Thomas Nagel embrace a naturalistic conception of mind and are also property dualists--believing that the mind is irreducible to the material.
Of course, mind is not reducible to the material, except insofar as it is a property of a material organism. A thought is not a material object. The problem I have with dualism is that is presupposes that mind and matter are two separate, independent substances. But mind cannot exist independently of matter, since to be conscious is to be conscious in a particular form, which is determined by the nature of one's physical sense organs. Since it has no sense organs, an immaterial consciousness would have no specific form of awareness, and could not, therefore, be conscious. Mental phenomena such as memories, imagination and dreams depend on the data of awareness gained through sensory perception. Mind is a property of a living organism, and cannot exist outside of that context.

William responded:

True enough, but survival value, as I've pointed out elsewhere, is not a sufficient or necessary condition for truth (or true beliefs).   

You wrote: 
[R]rationality (conceptual knowledge) enables man to respond to his environment in a way that the lower animals cannot.
I agree, but this does not entail that our responses to reality give rise to true beliefs.  All we can say is that we've been able to respond to reality in such a way as to continue surviving. 

I wrote:  "Non-material consciousness is not necessarily supernatural. Philosophers of mind like David Chalmers and Thomas Nagel embrace a naturalistic conception of mind and are also property dualists--believing that the mind is irreducible to the material."

So the problem you have with dualism is that it's dualistic. 
But mind cannot exist independently of matter, since to be conscious is to be conscious in a particular form, which is determined by the nature of one's physical sense organs. Since it has no sense organs, an immaterial consciousness would have no specific form of awareness, and could not, therefore, be conscious.

Mind is a property of a living organism, and cannot exist outside of that context.

You've presented this argument a couple of dozen times by now, and it remains just as unconvincing as when you first gave it. 

As I've said on another thread, the form of awareness of an immaterial substance would be that of apperception, which is an introspective awareness of mental content. 

God, as an immaterial substance, would have no need of sense organs, insofar as he would know all truths as part of his essence or nature.  By perfectly contemplating himself and by fully knowing the effects of his will in creation, God would be omniscient.  No sense perception necessary.

The point is that rationality enables man to satisfy his needs in a way that the lower animals cannot. -- i.e., by acquiring knowledge and applying it to the problem of survival. The acquisition of knowledge in order to meet our survival needs gives rise to true beliefs. False beliefs are self-defeating. A suicide bomber who believes that by killing himself, he will achieve everlasting life becomes a victim of his own delusional thinking. It is only the correct identification of reality that promotes human survival.

So the problem you have with dualism is that it's dualistic.
I explain the problem to which this leads in the very next sentence.

Continuing, "But mind cannot exist independently of matter, since to be conscious is to be conscious in a particular form, which is determined by the nature of one's physical sense organs. Since it has no sense organs, an immaterial consciousness would have no specific form of awareness, and could not, therefore, be conscious.

You can't have apperception without perception, nor introspection without extrospection. Mental content depends on an awareness of an external world, since again, a consciousness conscious of nothing but itself is a contradiction in terms. Before it could identify itself as consciousness, it would have to be conscious of something. As I said in the statement you quoted, "Mental phenomena such as memories, imagination and dreams depend on the data of awareness gained through sensory perception." Observe that the apperception of which you speak does itself take a particular form, which corresponds to the sensory form that it reflects. What you apperceive in your mind's eye always takes a particular form that corresponds to one or more of your five senses. Imagination or apperception would be impossible without the content provided by sensory perception itself.
God, as an immaterial substance, would have no need of sense organs, insofar as he would know all truths as part of his essence or nature. By perfectly contemplating himself and by fully knowing the effects of his will in creation, God would be omniscient. No sense perception necessary.
This is simply an arbitrary assertion, with no empirical or logical support. Consciousness is a faculty of a "material substance," a faculty which requires physical sense organs and a brain. Eliminate these and you've eliminated consciousness.

Animate matter? Could you define what animate matter is? Don't you mean beings that are independent of necessary determinism? You recognize that there is a difference between a human and a rock. The question is not "are humans matter in motion," but "is that all that humans are?" This is the question that you have avoided answering and your cosmology does answer in the affirmative. And thus the contradiction between your experience and your cosmology.

We know that matter in motion must follow the laws of nature. We do not see particles traveling across the galaxy and deciding to make a left turn at the next nebula. We do not see Jupiter change its orbit because it wants to. It is because matter in motion is necessarily determined that science works. Yet we have the experience of independence and free thought. It is because you experience independence and free thought and are not necessarily determined that you can do science. So, do we experience independence because the matter in our heads is no longer matter or because that matter is still matter, but it is no longer bound to follow the laws of nature as other matter must? Or is there something else there? Perhaps, you have another option?

The non-rational animals, which evolved from lower forms of (plant) life, acquired the attribute of awareness. which plant life does not possess. Man, who evolved from more primitive forms of animal life, acquired the attribute of rationality, which the lower animals do not possess.
The word "evolved" in the above is nothing more than a synonym for the phrase "the magic happened here." Simply naming some matter "animate" and naming other matter "sentient" doesn't answer my above questions. But it does show that you recognize the difference. What you are suggesting is that, magically, the inanimate became animate and the non-sentient became sentient. You are suggesting that matter in motioned that is necessarily determined,  all by itself, became something other than matter in motion that is necessarily determined.

What you offer here is not a demonstration of how you get from the elements of your cosmology to knowledge, but merely a statement of faith that you can. If you want to convince me that it is possible to get to knowledge from your cosmology, offer the demonstration, that would end the discussion. Or you could ed this discussion by admitting there is no such demonstration.

Brendan: "...we do not need to investigate round objects to justify the claim that ‘all circles are round’ ..."

Ed: “We, initially, did (when the roundness of circles had to first be perceived in order to be believed...”

You can perceive round objects but you cannot perceive “roundness”, although if you are a realist on universals, you could claim to ‘directly apprehend’ or ‘intuit’ roundness.

But if you reject the real existence of universals, as Rand does, then ‘roundness’ is a concept, in which case it cannot be perceived in the way that we perceive material objects external to the mind.

Having said that, it’s true that one must understand the terms ‘all’, ‘circle’, ‘are’ and ‘round’ in order to understand that ‘all circles are round’. But that’s not the same as perceiving roundness.

And thus the contradiction between your experience and your cosmology.
Brady, I didn't use the term "animate matter"; I said "inanimate matter." Inanimate matter is simply non-living matter, e.g., rocks, water, etc. When you ask me if "matter in motion" is "all" that human beings are, are you simply asking if I believe that human beings are no different from a rock? Of course, human beings differ from rocks. A rock is an inanimate object; a human being is a living organism with a rational mind. Big difference. But to say that human beings are rational animals doesn't mean that they aren't material organisms.

As for being "independent of necessary determinism," everything is determined by its nature -- by the kind of entity it is -- not just inanimate matter. But that doesn't mean that everything is governed by the same principles of causal necessity. Plants differ from rocks in the kind of action possible to them (i.e., growth and self-sustenance through photosynthesis), but the action of plants is still a necessary consequence of their natures and of the environment in which they live. Similarly, the kind of action possible to an animal differs from that of plants, but is still governed by causal necessity, although the causal necessity is of a different order; viz., the animal's conscious awareness in conjunction with its needs and desires are what determine its action. Human beings, who also possess conscious awareness, have a rational faculty, which gives them a greater range of abilities and powers in the service of their lives and interests, but I would argue that they too are governed by causal necessity. They necessarily choose their actions according to what they perceive to be their highest values. It is their values that motivate their actions, but on a much more sophisticated level than that of the lower animals.

The difference between inanimate matter, on the one hand, and living organisms like plants, animals and human beings, on the other, is not that former is governed by deterministic necessity whereas the latter are not. The difference is that inanimate matter is governed by mechanistic causation, whereas living organisms are governed by teleological causation.
We know that matter in motion must follow the laws of nature. We do not see particles traveling across the galaxy and deciding to make a left turn at the next nebula. We do not see Jupiter change its orbit because it wants to. It is because matter in motion is necessarily determined that science works.
You have an unnecessarily restrictive view of science. Science isn't restricted to physics. There are the sciences of biology, physiology, psychology and the social sciences as well.
Yet we have the experience of independence and free thought. It is because you experience independence and free thought and are not necessarily determined that you can do science. So, do we experience independence because the matter in our heads is no longer matter or because that matter is still matter, but it is no longer bound to follow the laws of nature as other matter must? Or is there something else there? Perhaps, you have another option?
We are certainly not bound, like inanimate matter, by the laws of mechanistic causation, but that is not because we are somehow non-material. The fact that we are composed of atoms, electrons, proton, neutrons, etc., which are subject to the laws of physics, does not mean that we must act mechanistically as human beings. As I pointed out on the "Objectivism and Atheism" thread, the whole is more than the sum of its parts, but that does not imply some mysterious supervening principle of order or entelechy. A human being, as a whole, exhibits different principles of action than the parts of which he or she is composed, because a human being is a different kind of material entity than the parts themselves, viz., an integrate or integration of the parts.

I wrote, "The non-rational animals, which evolved from lower forms of (plant) life, acquired the attribute of awareness. which plant life does not possess. Man, who evolved from more primitive forms of animal life, acquired the attribute of rationality, which the lower animals do not possess."
The word "evolved" in the above is nothing more than a synonym for the phrase "the magic happened here." Simply naming some matter "animate" and naming other matter "sentient" doesn't answer my above questions.
Again, I didn't use the term "animate matter"; the term was "inanimate matter." And the fundamental difference is not between inanimate matter and sentience; it is between inanimate matter and life. Not all life is sentient; vegetative life is non-sentient, but it is still life.

Why do you say that "evolved" suggests something magical. Things act according to their natures; the fact that we don't understand how to produce an animal or a human being from scratch in the laboratory does not mean that biological evolution is magical or miraculous. Life evolved gradually over millions of years, and we have some idea of the processes that brought it about, not enough to create the higher forms of life artificially, but enough to understand something of their creation. What you want to say is that if we don't know enough to reproduce them artificially, we must, therefore, attribute the process to a conscious, immaterial creator, for which we have absolutely no concrete evidence whatsoever, and which, moreover, contradicts everything we know about the nature of consciousness, i.e., that is a faculty of a living organism. Instead of being the origin of life, consciousness is the result of a long chain of biological evolution. It is the consequence of living processes, not their cause.

I continue to be amazed about your habit of ignoring reponses I make to your assertions, and then simply repeating these assertions as if they were never challenged. 

A few weeks back on the "Objectivism->atheism;~atheism, therefore ~Objectivism" thread, you asserted something very similar to what you've asserted here, viz.: 
To say that reason is man's basic tool of survival is not to say that reason shouldn't be directed towards recognizing the truth and correctly identifying reality, for it is by doing so that one best serves the goal of human survival.
At that time, I responded with the following, and did not receive a reply from you: 

--Not necessarily.  An action or form of behavior X can follow from any number of belief-desire combinations, not necessarily that which is true.  Alvin Plantinga, for example, offers the following meditation: 

"Paul is a prehistoric hominid; the exigencies of survival call for him to display tiger avoidance behavior. There will be many behaviors that are appropriate: fleeing, for example, or climbing a steep rock face, or crawling into a hole too small to admit the tiger, or leaping into a handy lake. Pick any such appropriately specific behavior B. Paul engages in B, we think, because, sensible fellow that he is, he has an aversion to being eaten and believes that B is a good means of thwarting the tiger's intentions.  But clearly this avoidance behavior could result from a thousand other belief-desire combinations: indefinitely many other belief-desire systems fit B equally well. Perhaps Paul very much likes the idea of being eaten, but when he sees a tiger, always runs off looking for a better prospect, because he thinks it unlikely that the tiger he sees will eat him. This will get his body parts in the right place so far as survival is concerned, without involving much by way of true belief. Or perhaps he thinks the tiger is a large, friendly, cuddly pussycat and wants to pet it; but he also believes that the best way to pet it is to run away from it. Or perhaps he confuses running towards it with running away from it, believing of the action that is really running away from it, that it is running towards it; or perhaps he thinks the tiger is a regularly reoccurring illusion, and hoping to keep his weight down, has formed the resolution to run a mile at top speed whenever presented with such an illusion; or perhaps he thinks he is about to take part in a 1600 meter race, wants to win, and believes the appearance of the tiger is the starting signal; or perhaps . . . . Clearly there are any number of belief-cum-desire systems that equally fit a given bit of behavior."-(Alvin Plantinga:  An Evolutionary Argument Against Naturalism, Lecture Notes)--

This clearly shows that false beliefs are in fact not necessarily self-defeating, contra your assertion.   

The question is whether you'll retract your position, or simply reassert, for a third time--and in blissful ignorance of my challenge--that false beliefs are evolutionarily self-defeating. 

What you apperceive in your mind's eye always takes a particular form that corresponds to one or more of your five senses. Imagination or apperception would be impossible without the content provided by sensory perception itself.
I've refuted this contention on the "Objectivism and Atheism Thread", Post 179.

The acquisition of knowledge in order to meet our survival needs gives rise to true beliefs. False beliefs are self-defeating."

Liebniz repllied,
I continue to be amazed about your habit of ignoring reponses I make to your assertions, and then simply repeating these assertions as if they were never challenged.
If I did this, I apologize. I had no intention of ignoring your responses. I may simply have overlooked them. In any case, I will make a special effort to answer you here, and if there are any other points that you think I haven't addressed, please let me know.

A few weeks back on the "Objectivism->atheism;~atheism, therefore ~Objectivism" thread, you asserted something very similar to what you've asserted here, viz.:
To say that reason is man's basic tool of survival is not to say that reason shouldn't be directed towards recognizing the truth and correctly identifying reality, for it is by doing so that one best serves the goal of human survival.
At that time, I responded with the following, and did not receive a reply from you:
--Not necessarily. An action or form of behavior X can follow from any number of belief-desire combinations, not necessarily that which is true.
Alvin Plantinga, for example, offers the following meditation:
"Paul is a prehistoric hominid; the exigencies of survival call for him to display tiger avoidance behavior. There will be many behaviors that are appropriate: fleeing, for example, or climbing a steep rock face, or crawling into a hole too small to admit the tiger, or leaping into a handy lake. Pick any such appropriately specific behavior B. Paul engages in B, we think, because, sensible fellow that he is, he has an aversion to being eaten and believes that B is a good means of thwarting the tiger's intentions. But clearly this avoidance behavior could result from a thousand other belief-desire combinations: indefinitely many other belief-desire systems fit B equally well. Perhaps Paul very much likes the idea of being eaten, but when he sees a tiger, always runs off looking for a better prospect, because he thinks it unlikely that the tiger he sees will eat him. This will get his body parts in the right place so far as survival is concerned, without involving much by way of true belief. Or perhaps he thinks the tiger is a large, friendly, cuddly pussycat and wants to pet it; but he also believes that the best way to pet it is to run away from it. Or perhaps he confuses running towards it with running away from it, believing of the action that is really running away from it, that it is running towards it; or perhaps he thinks the tiger is a regularly reoccurring illusion, and hoping to keep his weight down, has formed the resolution to run a mile at top speed whenever presented with such an illusion; or perhaps he thinks he is about to take part in a 1600 meter race, wants to win, and believes the appearance of the tiger is the starting signal; or perhaps . . . . Clearly there are any number of belief-cum-desire systems that equally fit a given bit of behavior."-(Alvin Plantinga: An Evolutionary Argument Against Naturalism, Lecture Notes)--
This clearly shows that false beliefs are in fact not necessarily self-defeating, contra your assertion.
My point was not that false beliefs were necessarily self-defeating in any given situation, but that recognizing the truth and correctly identifying reality is the best method for promoting the goal of human survival. It is in that respect that rejecting knowledge in favor of ignorance, or truth in favor of falsehood, is self-defeating. Question: Which gives you a better chance of survival while driving your car? Driving blindfolded or driving with full knowledge of where you are going? Clearly, the latter. It is in this respect -- as a method of dealing with reality -- that knowledge and truth are superior to ignorance and falsehood.

I wrote, "What you apperceive in your mind's eye always takes a particular form that corresponds to one or more of your five senses. Imagination or apperception would be impossible without the content provided by sensory perception itself."
I've refuted this contention on the "Objectivism and Atheism Thread", Post 179.
And I answered you on the same thread, in Post 188. :-)

The whole point is that it need not be, and that other belief-desire combinations (false ones) can be just as effective for promoting survival. 
It is in that respect that rejecting knowledge in favor of ignorance, or truth in favor of falsehood, is self-defeating.
That respect doesn't pass, though, as has just been demonstrated. 
Question: Which gives you a better chance of survival while driving your car? Driving blindfolded or driving with full knowledge of where you are going? Clearly, the latter.

You need not have full knowledge of where you're going in order to drive safely.  You could very well imagine you're in Zanzibar driving on roads constructed by UFOs, or navigating the innards of a cow's stomach, or trapped in a video game such as Grand Turismo-- and still drive perfectly safely. 

So, no, knowledge and truth are clearly not necesssarily superior to ignorance and falsehood with respect to survival promotion.

Liebniz,

I meant "full knowledge" within the relevant context -- driving blindfolded vis-a-vis knowing what's ahead of you in the road. More to the point, why do you think people place so much emphasis on education? Because they realize its importance for their well-being and survival. I can't believe you're seriously disputing this!
