Arguments against Soul

[The Grand Nudger]

But the colour-blind scientist doesn't ever have knowledge of the personal experience of seeing red (by definition).  

Negatron.  That's the contradictory assertion fundamental to the logical misapprehension, not anything that follows by definition.  If our color scientist knows everything about color, knowledge of a personal experience of color is included -in- that knowledge, regardless of whether it was personally experienced.  That's part of everything.

The same would be true of god and knowledge.  If god knows everything about bad, then knowledge of a personal experience of bad is included -in- that knowledge, regardless of whether or not god had the experience, or how god came to possess the knowledge.

[Jehanne]

What do you guys here think, what is the best argument against the existence of the soul (and therefore ghosts and afterlives)?
I used to think that the "Damage of the middle of the brain leads to two distinct personalities governing halves of the body." was an argument that would convince anybody, but, evidently, it won't. See here:
How do people who believe in souls explain away the fact that epileptic patients who have the middle of their brain severed appear to have two distinct personalities governing halves of their bodies?
In short, people respond with "Where is some reliable source for that claim?", and, to be honest, I am not sure what would be a reliable source for this. My psychology textbook saying that isn't really good evidence that's true, is it? I mean, my Croatian history textbook tells me most scientists agree Global Flood really happened.
Perhaps the best response to that is "And where is some reliable source of the claims about Maria's Shoe, and other things that supposedly prove the existence of soul?", what do you think?

The existence of an immaterial soul would violate the Conservation Laws, namely, Energy, Momentum and Angular Momentum, for which, no exceptions whatsoever, to date, have been found.  Given modern technology, infrared, magnetic and electric field detectors, the existence of an immaterial soul could be quickly, and definitively, established.

As for veridical experiences for near-death experiences, such have been looked for, under controlled conditions, without success; as such, those accounts fall into the same category as Travis Walton's abduction by aliens in California.

What is an immaterial soul like, and how do we know it would violate those laws?

How do we know that a soul is detectable by those means? 

Is there anything that reasonable people hold to be real which isn't detectable by those means?

[EgoDeath]

Belaqua... forever the contrarian, and never actually makes a single claim about what he believes. I second the idea that he's in the Christian closet.

How do we know that a soul is detectable by those means?

The memory capacity of the human brain is about one Terabyte. This does not mean our brains are full to the 1tb capacity, not everyone speaks twenty languages or can memorise the entire Catechism of the Catholic Church. It matters not if a brain is half empty or full, this is still an enormous amount of data to be correlated, indexed and filed away for quick access. That big fatty lump of meat in our heads does a very good job of this, mostly.

I am told that upon the event of my death a snapshot of my entire life is recorded by an as yet unidentified process, in an as yet unidentified medium. Since the beginning of the Christian story these souls now number in the many billions and in order for them to function they need a power source, an energy supply, which would be all pervasive throughout the universe and if such a force were to exist it would stand out like a diamond on a goat's arse.

One of more of these:

1. Gravitational Force
   
2. Weak Nuclear Force.
   
3. Electromagnetic Force.
   
4. Strong Nuclear Force.
   

Would spot it. But they don't. Here's why.

Claims that some form of consciousness persists after our bodies die and decay into their constituent atoms face one huge, insuperable obstacle: the laws of physics underlying everyday life are completely understood, and there’s no way within those laws to allow for the information stored in our brains to persist after we die. If you claim that some form of soul persists beyond death, what particles is that soul made of? What forces are holding it together? How does it interact with ordinary matter?

There's no way around this. But that won't stop you from trying.

OK, this seems like a good explanation of how you picture what a soul would be, if it existed. 

First, that it contains memories and knowledge. Second that it survives after death. Third, that it would need an energy source. 

So at the beginning, we're talking about a very specific type of thing. I am not committed to there being a soul or, if there is one, what it would be like, so it's interesting to me that this is the type of thing you're talking about. 

I think it's likely that the first two (knowledge and survival) are in line with what many Christians believe. 

How about the third one? Since I don't know what a soul is or how it could survive, I don't see yet why it would need an energy source.

I'm not trying to do or prove anything, except to see why people here believe what they do. 

It seems clear from what you're saying that you expect a soul, if it existed, to be a natural force or operation, possibly with some physical body as substrate, that would be detectable through the laws of physics that we currently understand. Is this a fair summary of your position? 

In the Platonic and Aristotelian traditions, souls are said to be purely noetic or ideal. That is, they have more in common with numbers and other ideal objects than with, say, gas or magnetic fields. Some people in these traditions think that such an ideal object must exist in conjunction with a physical body, and some don't. If they are right, though, and a soul is something like a number -- a form or idea -- then I don't see how any physical test could detect it. 

Do you have reasons to rule out the common traditions? Does the article you link to address this ancient view?

Love?*

To me love is more like a disposition that a person finds in himself. Desire, especially. I don't think I'd call that a material object in itself. I was thinking more along the lines of Dark Matter, though I am happy to confess that I don't know anything about that stuff.

It seems to me possible that there are things in the universe which physics hasn't yet described, particularly since physics can't even tell us what gravity is -- though we know what it does.

Edited to add:

I looked at the link you provided. It doesn't say anything about a soul, so I don't see why it's relevant here.

He does say something interesting about gravity: he claims that since we know what it does then we know what it is. A lot of people (including Galileo) would disagree with him about that.

[The Grand Nudger]

I'm not sure what relevance a general "there are things we don't know" comment could be here. Sure, absolutely there are. Soul is hardly one of those things. We're subject matter experts, being their authors.

It's possible to measure electrical currents on on the picoamp scale.  I don't know how it could be done, but it would probably involve an oscilloscope.

I am making an argument against the existence of an immaterial soul and/or spirit.  If souls exist, how do such interact with matter?
