That shows consistency but nothing else. A delusion dearly held is not correct for being consistent.

Hi Wolfgang, Entropy can be defined in several ways. However the order/disorder interpretation is fraught with difficulties. The biggest one is actually defining what disorder is (read the Wikipedia entry on entropy). In your example we know that some of the gas in the box must have ended up in the just hatched chick. This is an increase in order. We can argue that 1 thing (an egg) has become 1 thing (a chick) and that has not affected the order of the system. It looks like you take the view that an egg is more ordered than a chick because the chick results from "blind downhill processes" and this overwhelms any other increase in order....In a previous post I presented a more detailed variant of the paradox:
We can put the just fertilized egg together with enough atmosphere of the right temperature in a big enough box and consider the whole box as a closed system. The composition of the air in the box will change during the development of the chick, but to consider this change as a decrease in order seems quite absurd to me. Because the box with the just hatched chick is considered a state resulting only from blind downhill processes affecting previous higher-order states, we must conclude:The box with the just hatched chick is less ordered than the box with the just fertilized egg....
Cheers, Wolfgang
No, you argue against several scientific principles by trying to point out their inconsistencies or errors. But your arguments reveal that you do not understand those areas of science, since they point out things that aren't so.You haven't found any logical inconsistency in my text, you only enumerated what must be wrong if your world view is essentially right. And it should be obvious that what you consider a "complete misunderstanding" of "basic scientific principles", I consider only a disagreement between panpsychism (acknowledging the reality of souls) and the prejudices of your materialist world view.
Irrelevant to the argument, and wrong. Evolution deals only with what happens to life over the course of time. It does not deal with how life got started. ToBy the way, I'm a consequent, consistent evolutionist, not admitting such discontinuites as between abiogenesis and Darwinian evolution or between an evolution without any form of consciousness and a sudden appearence of consciousness (see also http://groups.google.com/group/talk.origins/msg/ebd48940eb2a79a6).
You do lack understanding, as your arguments reveal.In cases where I do not believe in orthodox science (e.g. particle physics), you simply conclude that I lack understanding.
It is naive. You compare apples and oranges, and marvel that they aren't the same. Of course they're not the same, whoever said that they were?And that you consider the short chapter Mechanical and Living Systems as "thoroughly naive" is quite revealing.
Heat.You write: "A newly hatched chick is more ordered than a raw egg, since the egg requires an input of energy to form the chick, thus decreasing the entropy of the system."
What kind of energy input? In a previous post I presented a more detailed variant of the paradox:
If the system is closed then the total entropy of the system will not change. You again show your lack of understanding of entropy. If the air in the box is warm enough the chick will form in the egg, and the air in the box will cool down. The cooling is a loss of energy to the egg. The air loses heat (and increases its entropy) whilst the egg forms into a chick (and decreases its entropy) whilst the entropy of the system (air plus chick) remains constant.We can put the just fertilized egg together with enough atmosphere of the right temperature in a big enough box and consider the whole box as a closed system. The composition of the air in the box will change during the development of the chick, but to consider this change as a decrease in order seems quite absurd to me. Because the box with the just hatched chick is considered a state resulting only from blind downhill processes affecting previous higher-order states, we must conclude:
The box with the just hatched chick is less ordered than the box with the just fertilized egg.
The population of Giant Pandas has been dropping steadily for a very long time, and the reason is ridiculously simple. At some point in the past, the Panda went from being a carnivore to being a vegetarian, eating a diet of little but bamboo. The reason for this change is unknown, but maybe the animals they ate became too rare to give them a steady food source so they started eating the most abundant food available to them - bamboo. Whatever the reason for this change the gut of the Panda is not equipped to draw enough energy from the bamboo to allow them to do much except eat, sleep and defecate, and mating and gestation both require energy. So Pandas don't like to mate, and when they do there is a high rate of miscarriage. Their captivity has allowed the population to increase from the wild population. If you ever get the chance you should visit the Giant Panda centre in Chengdu, Sichuan province where they do a lot of research and breed Pandas very successfully. You might learn a few things.Why do you think that the low fertility of the Giant Panda cannot be explained by the psychon theory? The more these pandas are protected, the lower is their mortality and subsequently also their fertility. And that an increasing number of Giant Pandas in captivity leads to a decreasing number in the wild, is also an elegant consequence of the psychon theory. Because of the small population size of the Giant Panda one could perform a crucial experiment: killing all individuals being old or not 100% healthy in order to create a baby-boom.
In any case, if animals were essentially machines without souls, as you assume, then it should be possible to relevantly increase the population size of the Giant Panda, at least by artificial insemination or by cloning.
Strange how food and habitat do make such a difference then. Take for example the rabbit population in Australia. When rabbits were introduced to Australia they underwent an exponential population growth, exactly analogous to the one you suggest would be the case for reductionist materialism.According to reductionist materialism, apart from food and habitat, nothing hinders a species from exponential growth. In reality however, the population size of a species is limited by the number of corresponding souls.
Entropy can be defined in several ways. However the order/disorder interpretation is fraught with difficulties. The biggest one is actually defining what disorder is (read the Wikipedia entry on entropy).
If you want to talk about scientific processes and laws you need to use the same definitions as they do, otherwise you're just talking garbage.My argument is essentially independent from such definitions.
That's actually nearly correct!Blind downhill processes lead from a state of lower probability to a state of higher probability. A good example is decay in general or the decay of a bacterium after death in special. Another example is the dilution by random movements of a group of particles suspended in a liquid (Brownian motion).
Imagine that one autotroph bacterium starts replication in a corresponding culture medium and that after some time the culture medium is full of bacteria. According to common sense, the transformation of simple molecules into such highly complex chemical factories constitutes not only a transformation from a state of higher probability into a state of lower probability but also an increase in order.
No, since the laws of QM are probabilistic, not deterministic, no such precise simulation is possible. It would be possible to produce a simulation that gave a probable outcome, but not a certain outcome, as is possible for Newtonian mechanics.In the case of e.g. gravitation (of our planetary system) or Brownian motion, computer simulations can easily be made, because what happens in nature can be well explained by physical laws. In case of life however, simulations based on physical or chemical laws do not exist. Why? Those believing in quantum mechanics sometimes claim that such simulations are possible in principle, but that the needed computing power exceeds all existing computers.
Try watching this video instead. Simple evolution with no guiding thought process.However, I'm convinced that every unprejudiced examination leads to the conclusion, that no physical laws (as the basis of chemistry and biochemistry) can be formulated and implemented as a computer simulation in order to explain e.g. the construction of the Bacterial Flagellum, as shown in this animation.
There is no must about it. You're just anthropomorphising again.The behaviour of such enzymes must be explained by assuming that they somehow are able to sense their environment and to perform goal-directed movements.
It is an argument from incredulity, to whit, you can't believe that such a thing could happen without the enzymes being able to sense their environment. Pretty much the definition of an argument from incredulity - "I can't believe that that could happen unless the enzymes can sense their environment, therefore they must sense their environment".This only means that enzymes resemble rather insects than the dead particles of Brownian motion.
That's not an argument from incredulity,
There's your problem, right there. A lot of science is contrary to "common" sense, and if you throw out stuff just because it doesn't make sense to you then you are again making an argument from incredulity.but from common sense
I'll admit that your reasoning might possibly be consistent.and from consistent logical reasoning.
I really can't say anything to damn your ideas more than your own words do right here.By the way, the less one knows and understands, the more seems possible.
Here's my contribution: if you rearrange the letters in 'wogoga' you get 'woo gag'?
Because the box with the just hatched chick is considered a state resulting only from blind downhill processes affecting previous higher-order states, we must conclude: The box with the just hatched chick is less ordered than the box with the just fertilized egg.
If the system is closed then the total entropy of the system will not change.
If the air in the box is warm enough the chick will form in the egg, and the air in the box will cool down. The cooling is a loss of energy to the egg.
Ah, thanks for the link to your post 96, I hadn't read that one.The cornerstone of demographic saturation is not "a declining growth rate" but a growth resp. decline rate of zero after a population is saturated (see my post #96). And because "there is no obvious reason why families should adjust their behaviour to achieve long-term population replacement", the fact that the populations (corrected for migration) of many developed countries and regions have remained rather constant over years or decades instead of exponentially increasing or decreasing is not only astonishing from the viewpoint of standard demography but also very improbable.
In a closed system"The second law of thermodynamics states that entropy in the combination of a system and its surroundings (or in an isolated system by itself) increases during all spontaneous chemical and physical processes." (Wikipedia)The second law is a logical consequence of the randomness of molecular motions. That a big enough number of random motions can only transform a state of lower probability into a state of higher probability is obvious.
No, it's complete nonsense. We can reduce our local entropy at the cost of an increase in global entropy.However, humans can transform states of higher probability into states of lower probability, because we are able to sense our environment and are able to purposefully move our bodies. The same is valid also for animals and for bacteria.
Here's my contribution: if you rearrange the letters in 'wogoga' you get 'woo gag'?
I apologise, you are correct, the entropy of a closed system can increase, but not decrease."The second law of thermodynamics states that entropy in the combination of a system and its surroundings (or in an isolated system by itself) increases during all spontaneous chemical and physical processes." (Wikipedia)
The Earth, as has been pointed out by others, is not a closed system, so the entropy of the Earth can decrease with no contradiction of the 2nd law of thermodynamics.The second law is a logical consequence of the randomness of molecular motions. That a big enough number of random motions can only transform a state of lower probability into a state of higher probability is obvious. However, humans can transform states of higher probability into states of lower probability, because we are able to sense our environment and are able to purposefully move our bodies. The same is valid also for animals and for bacteria.
Not a closed system. An input of energy can spontaneously decrease the entropy of a system with no need for conscious intent.But what about DNA polymerase enzymes which replicate DNA in vitro? The decay of DNA is the normal reaction, leading to a state of higher probability. Therefore, such enzymes doing the opposite create states of lower probability. Because random motions only could create states of higher probability, we are forced to admit: the motions of such enzymes are not random.
And yet the eggs still need a constant input of heat energy."It has been reported that during incubation, large eggs produce more heat than small eggs. Large eggs also face more difficulties to remove the surplus heat from the egg, as a result of the decreasing ratio between egg surface and egg content with increasing egg size and the reduced air velocity over the eggs in commercial incubators." (Source)
No, because such a perpetuum mobile would require constant replacement of the reactant chemicals, which would take more energy than that released by the reaction. It would also require a heat source to supply the heat or it would rapidly reduce its surroundings to absolute zero.A decade ago, I wrote in a discussion with somebody who argued like you:
"Your comments show a further time that you do not understand at all the (original) second law. This law is aequivalent to the impossibility of a perpetuum mobile of the second kind. What you write is exactly the contrary: thermal energy can be transformed into energy of chemical bonds. It would be possible to convert thermal energy without temperature differentials into chemical energy. If certain bonds are built up at a temperature of about 37° Celsius, there must be other bonds which can be built up at lower temperatures, e.g. 10° Celsius. In any container we could produce chemical energy by simply cooling down the environment!"
But now I had to learn:
"On the other hand, some reactions need to absorb heat from their surroundings to proceed. These reactions are called endothermic. A good example of an endothermic reaction is that which takes place inside of an instant 'cold pack.' Commercial cold packs usually consist of two compounds - urea and ammonium chloride in separate containers within a plastic bag. When the bag is bent and the inside containers are broken, the two compounds mix together and begin to react. Because the reaction is endothermic, it absorbs heat from the surrounding environment and the bag gets cold." (Source)
Yet this could be further evidence for what I wrote at that time:
"Most time of my life I have been sure that a perpetuum mobile of the second kind is not possible, but now I'm no longer sure."
In case of life however, simulations based on physical or chemical laws do not exist. Why? Those believing in quantum mechanics sometimes claim that such simulations are possible in principle, but that the needed computing power exceeds all existing computers.
No, since the laws of QM are probabilistic, not deterministic, no such precise simulation is possible. It would be possible to produce a simulation that gave a probable outcome, but not a certain outcome, as is possible for Newtonian mechanics.
Nope. I said that it's only possible to produce probabilistic models in QM. That doesn't mean that the actual evolution of the flagellum is impossible. One is a predictive model, which can only be probabilistic in nature. The other is reality, which has already happened. It can be explained in terms of QM, but it can't be predictively modelled.So you concede that the rather deterministic than probabilistic construction of the bacterial flagellum cannot even in principle by explained by quantum mechanics and similar theories?
No. The Miller–Urey experiment was an ad-hoc experiment, which shocked everyone involved by actually producing biochemical building blocks. Furthermore, the concentrations required are unknown, although estimates may exist, nobody can be certain.And here you can find a short refutation of the hypothesis that a bacterium-like Adam as the result of purely materialist abiogenesis could have started Darwinian evolution. By the way, one should not forget that the existence of a high enough concentration of corresponding building blocks (simple organic molecules) is a prerequesite for any materialist trial-and-error abiogenesis process to start. The famous Miller–Urey experiment is strong evidence against such a high concentration of the needed building blocks on the early earth.
Why did those souls move from Europe to the US, when Europe was also going through a baby boom? Where did those spare souls come from, when, despite all the deaths in WWII, the population of Europe significantly increased between 1930 and 1950?The baby boom in the United States caused by the many deaths in Europe during World War II is a good example showing that souls "move from country to country".
There's also a wee bit of a problem there if ethnicity is a factor in the distribution of souls, because I don't recall that the baby boom over here reflected the great losses of certain ethnic groups in the holocaust. It might be hard to figure out for large and varied ethnic groups such as the Jews, since I'm sure American Jews participated well enough in the American baby boom, but smaller groups that were also heavily and disproportionately thinned in that time should have seen an enormous and equally disproportionate increase in their numbers that would stand out noticeably. American and Irish Gypsies and Travellers, for example, should have seen an unprecedented and conspicuous population explosion after the terrible toll paid by their European cousins. If not, why not?Why did those souls move from Europe to the US, when Europe was also going through a baby boom? Where did those spare souls come from, when, despite all the deaths in WWII, the population of Europe significantly increased between 1930 and 1950?

Nope. I said that it's only possible to produce probabilistic models in QM. That doesn't mean that the actual evolution of the flagellum is impossible.
Anthropomorphism. How do you know that the flagellum was the goal? This is a case of post hoc ergo propter hoc reasoning.The problem we are dealing with is the goal-directed construction of the flagellum by enzymes.
What problem? I directed you earlier to a youtube video showing one possible way it could have evolved. Each stage in the evolution model gives the bacterium an evolutionary advantage, which is precisely what you'd expect from undirected evolution.The even more problematic evolution of such a complex rotary engine (powered by the flow of protons across the bacterial cell membrane) is a different question.
That a result occurs is not surprising. The laws of QM are probabilistic. This means that it is impossible, a priori, to know for certain what the outcome will be. This does not mean that there will not be an outcome, just that you don't know what it will be before you start. Of course, building such an evolutionary model from QM would be extremely problematic in terms of computer memory and processing power, but if you could, and could run it a few billion times, you might well end up with a flagellum from one simulation.You wrote that "since the laws of QM are probabilistic, not deterministic, no such precise simulation (of the construction of the bacterial flagellum) is possible".
But how can the purely probabilistic laws of QM or similar be responsible for the very determined construction of such a complex rotary machine? How can the probabilistic behaviour of quanta lead to a rather deterministic behaviour of enzymes being capable of efficiently building such a complex machine?
That's so wrong it's off the chart. I never said simulations were impossible, I said the outcomes were probabilistic in nature, so for any particular post hoc result you may not get a simulation that matches it exactly. That doesn't mean the simulations are bad, or that the laws are wrong, just that there are a lot of possible outcomes.If QM-based simulations of the deterministic happenings in living cells are in fact impossible as a matter of principle, then it is a trivial logical consequence that QM cannot explain the happenings in living cells.
Unwarranted assumption.However, the non-deterministic nature of quanta resp. elementary particles can be seen in a new light: this non-determinism is a prerequisite that a psychon of a higher organisation-level can have an effect, because a fully deterministic nature of the parts would not allow any freedom to the whole.
Nope. The motion is determined by attractive and repulsive forces (those would be the electrons and protons at work). You're anthropomorphising, yet again.For instance, if a transcription factor in a human cell were fully determined by its electrons, protons and neutrons, then its movement as a whole would only resemble Brownian motion, but the transcription factor would not be able to find its destination on the incredibly long DNA. In order to do that, a transcription factor as a whole must be able to purposefully move (similar to migratory animals), and this implies an effect on the behaviour of its parts.
A lot of people have signed onto scientology and that fiction writer's pseudoscientific woo woo. It claims to cure all ills and make you perfect on earth while alive.. unlike most other religions. It has it all, and uses the same kinds of made up words about souls and past lives affecting the present.
All woogag has to do is tack on the cure for all ills... by curing the soul too. What sets the psychon straight to make the physical body perfect too?
New cult in the making?![]()
A bit of sideways drift here, but if you have never read Mark Twain's essay on Christian Science, you should.The $cientologists have their "body thetans" and this weirdo has his "soul-psychons"... if L. Ron Hubbard can get away with it, why not this jackass?
I swear that if I had no scruples and simply wanted to make a butt-load of money, then I'd start a religion/self-help/pseudoscience cult as well. Far too many folks seem susceptible to this kind of twisted thinking.
http://www.bestofmarktwain.com/christianscience.htmlChristian Science is Mark Twain's enduringly popular work that ridicules the Christian Science Church and pokes fun at its founder Mary Baker Eddy. Established in late 19th-century, the church put forward the principle of healing through prayer and greatly relied on the power of human imagination. Twain has brilliantly employed wit, humour, and satire to voice his views.
For of all the strange and frantic and incomprehensible and uninterpretable books which the imagination of man has created, surely this one is the prize sample. It is written with a limitless confidence and complacency, and with a dash and stir and earnestness which often compel the effects of eloquence, even when the words do not seem to have any traceable meaning. There are plenty of people who imagine they understand the book; I know this, for I have talked with them; but in all cases they were people who also imagined that there were no such things as pain, sickness, and death, and no realities in the world; nothing actually existent but Mind. It seems to me to modify the value of their testimony. When these people talk about Christian Science they do as Mrs. Fuller did: they do not use their own language, but the book's; they pour out the book's showy incoherences, and leave you to find out later that they were not originating, but merely quoting; they seem to know the volume by heart, and to revere it as they would a Bible-- another Bible, perhaps I ought to say. Plainly the book was written under the mental desolations of the Third Degree, and I feel sure that none but the membership of that Degree can discover meanings in it.
I might have missed some posts...
Am I right in thinking that has he yet to answer the Q about how he knows (i.e. why we should accept) that souls (and therefore psychons and everything else that rides on this whacky concept) are anything other than a feature of popular fantasy-fiction?
You might start with the Giant Panda and the Australian rabbit population.Psychon is a basic concept of a theory. Only by comparing the logical predictions of the whole theory with reality we can decide whether such psychons do exist or do not exist.
Why not?A world with a limited number of human and other souls, all being the result of evolution and representing a huge amount of information concerning e.g. instinctive behaviour and intelligence, cannot be identical to a world where living beings are essentially soul-less machines.
Except that your theory of demographic saturation has been shown to have holes in it large enough to drive an oil tanker through.So in order to decide whether psychons or reductionist materialism correspond better to reality, it is enough to look at empirical (e.g. demographic) data. Especially in demography it will become increasingly problematic to always explain after the fact by mutually inconsistent ad-hoc hypotheses what has been predicted before the fact by demographic saturation.
I don't oppose the concept of the soul, but have yet to see any evidence at all to support it.By the way, you seem to ignore the whole philosophical tradition, always having opposed the concept soul to the concept matter.
Please provide quotes from people who have become angry or admitted to feeling personally attacked. Such complaints usually precede the complainant leaving in a huff.And why do so many persons on such forums become angry or even feel personally attacked when they are confronted with a purely scientific concept, similar to a religious concept of the past.
Appeal to authority.Even before the advent of Christianity, Aristotle considered such concepts part of natural science. And do all the persons trying to ridicule panpsychism actually consider themselves superior to the outstanding panpsychists of the past such as e.g. Nicolas of Cusa, Giordano Bruno, Kepler, Spinoza and Leibniz?
Possibly. Possibly not. Or was that a rhetorical question?Could it be that such persons becoming angry when confronted with scientific hypotheses not agreeing with the prejudices of their current world view are in fact reincarnated religious zealots of the past?
Apples and oranges again. Descent from Adam and Eve never had any observable evidence to support it.We should not forget that our descent from Adam and Eve was once considered by the educated majority in the same way a fact as today reductionist materialism is considered a fact.
Try Especially in demography it will become increasingly problematic to always explain after the fact by mutually inconsistent ad-hoc hypotheses what has been predicted before the fact by demographic saturation

You might start with the Giant Panda and the Australian rabbit population.
Such a shame that your argument is rendered moot by the fact that the Red Panda and the Giant Panda aren't related. The Giant Panda is a bear, of the family Ursidae, which are carnivores. The Red Panda (Ailurus fulgens) is in a family of its own, and is actually most closely related to raccoons. See this paper.Concerning the Giant Panda you can find all what seems relevant to me in post #160. In post #164 you objected:
"The population of Giant Pandas has been dropping steadily for a very long time, and the reason is ridiculously simple. At some point in the past, the Panda went from being a carnivore to being a vegetarian, eating a diet of little but bamboo."
However, this would only be relevant if it had happened in recent times. If the Giant Panda population actually had substantially decreased in the last centuries and fertility were nevertheless so low that the population could not recover, then this actually would constitute strong evidence against my evolution-by-reincarnation theory. The assumption that the population of a related species* has been growing in the recent past at the expense of the Giant Panda is not plausible, because the only closely related species, the Red Panda has a similarly small number. So only a few thousand panda souls exist, and the populations of the two panda species are limited by their very low soul numbers.
*Such a situation could have happened at the end of the last ice age with elephant populations increasing at the expense of the mammoth populations.
How fortunate that there were all those spare rabbit souls floating about waiting for a population boom.The exponential growth of European rabbits in Australia at a time when these animals seen as agricultural pests were losing more and more of their habitat in Europe isn’t astonishing at all. Hundreds of millions of rabbit souls exist. And the decision to ban all rabbit farming in Australia even increased the problem.
"All rabbit farming for meat production was banned until 1987, when Western Australia changed its legislation to allow farming of rabbits in that state. New South Wales and Victoria followed suit in 1995 and 1997, respectively, and now farming for meat is allowed in all states with the exception of Queensland. Despite the ban on farming, Australia has had an established rabbit meat industry for many years, based on harvesting wild rabbits. In the early 1990s, over 2.7 million wild rabbits per annum were sold for meat. With the release, in 1996, of rabbit haemorrhagic disease as a biological control agent, the population of wild rabbits was dramatically reduced, with only 100,000 being harvested per annum in the late 1990s." (Farmed Rabbits in Australia)
Instead of banning rabbit farming, they should have captured wild rabbits and used them for farming. It is an obvious fact that domestication and aquaculture is paralleled by a decrease of the corresponding wild populations. So the decline (having started already in 1950) of wild rabbit populations in the 1990s was simply caused by the spread of rabbit farming in Australia and the rest of the world.
"The centre of world rabbit production is Europe, where demand is highest, accounting for 75 percent of world production. In 1990, total global production was estimated at 1.5 million tonnes." (Breeding rabbits for food and income)
To these 1.5 million tonnes rabbit meat of 1990 corresponded around 1 billion rabbits and at least 250 million rabbit souls, because rabbits are generally ready for slaughter at about 11-13 weeks of age when they weigh around 3 kg, and 50% of the weight at slaughter is meat (source).
It is an obvious fact that domestication and aquaculture is paralleled by a decrease of the corresponding wild populations.

Global production of farmed fish and shellfish has more than doubled in the past 15 years {1985 - 2000}. Many people believe that such growth relieves pressure on ocean fisheries, but the opposite is true for some types of aquaculture. Farming carnivorous species requires large inputs of wild fish for feed. Some aquaculture systems also reduce wild fish supplies through habitat modification, wild seedstock collection and other ecological impacts. On balance, global aquaculture production still adds to world fish supplies; however, if the growing aquaculture industry is to sustain its contribution to world fish supplies, it must reduce wild fish inputs in feed and adopt more ecologically sound management practices.
Nature 405 said:The worldwide decline of ocean fisheries stocks has provided impetus for rapid growth in fish and shellfish farming, or aquaculture. Between 1987 and 1997, global production of farmed fish and shellfish (collectively called 'fish') more than doubled in weight and value, as did its contribution to world fish supplies1. Fish produced from farming activities currently accounts for over one-quarter of all fish directly consumed by humans. As the human population continues to expand beyond 6 billion, its reliance on farmed fish production as an important source of protein will also increase.

I don't understand your reasoning
You had claimed that an alleged population decrease of the Giant Panda caused by low fertility is evidence against Giant Panda reincarnation.
your theory of demographic saturation has been shown to have holes in it large enough to drive an oil tanker through.
I answered that if such a population implosion had occurred in recent times, "then this actually would constitute strong evidence against my evolution-by-reincarnation theory".
you simply have to provide evidence for your original claim in order to seriously attack the psychon theory
The question of the relatedness between the Giant and the Red Panda is very interesting
For comparison: for every Red Panda soul more than one million human souls exist
