Introduction:
In this post, I am going to argue that souls exist. By souls, I don't mean the conventional, religiously based conception of souls. By soul, in this post, I simply mean that there is an aspect of humanity that is more than purely physical. I also hope to show that our evidence for the existence of souls is stronger than our evidence for the existence of the natural world.
In other words, I am about to argue that the evidence for the existence of your soul is better than the evidence for the existence of natural objects, for example, the statue of liberty.
Primer:
In my opinion, this argument will be somewhat difficult to understand, because it requires an uncommon kind of abstract and introspective thought. This is not to say that those who disagree simply cannot understand the argument; I simply ask that sufficient time is taken to think about what I have to say.
To 'prime the mind' to consider the subject material, consider the following scenario:
Lets say that an amazingly complex computer was invented. The computer is so complex
that it can make observations concerning its environment and make decisions. Now, here is a question: Would that computer be conscious? Would the computer have a first person perspective?
Here is a second question: How would we be able to tell?
Think about that for a few moments. How would we be able to tell whether or not the computer had first person perspecive?
If you don't personally think that computers could become complex enough to attain a state of self-awareness, what about growing a brain in a carefully regulated laboratory environment? Would that brain be self aware? What about animals? Are dolphins or elephants self aware? Do they see the world the way we see it? Do they 'think out loud' in their mind? I don't think there is any way to know definitely whether or not dogs, for example, are conscious. This concludes the primer section of this post. Now that we are thinking within the realm that my argument will reside within, the actual argument.
Why Souls Exist
First Person Perspective
Consider your own first person perspective. Think about the 'image' that you observe when you look at the world (http://honestsearchfortruth.blogspot.com/2013/09/the-screen.html). Is it possible for you to point at this image?
To illustrate my point, check out The Starry Night, by Vincent van Gogh:
You see the painting, correct? Excellent. Now, inside of your brain, does that image exist in the form that you perceive it right now?
Obviously, in a sense, yes. There are neural pathways in your brain that correspond to The Starry Night as your eyes transfer sensory input into your brain, and the brain interprets that information to generate a model of the world.
This is not what I am interested in, though. I am interested in knowing whether or not The Starry Night exists inside of your brain in the form that you see it right now. For example, if we dissected a brain, would we find an image of The Starry Night inside? Would we find the 'blue' of the painting anywhere? What about the 'yellow' of the moon?
The obvious answer is no. When autopsies of brains are done, we find nothing that is blue and yellow and takes on the form of the images we look at from our first person perspective.
Again, I'm not saying that the image doesn't exist in a translated and corresponding fashion inside of the brain. It most certainly does. But that is also irrelevant to the point I am trying to make.
There is no image inside of your brain that you could reach out and touch that looks anything like The Starry Night as you observe the painting.
When you stop at a traffic light, I challenge you to point out where in your brain a 'red light' is. You cannot touch 'red' inside of your brain.
Another example are the thoughts that we have. As you read this blog post, I suspect that you are 'thinking out loud' in your mind. I suspect that many readers will continue to think to themselves "Josh! All of this is going on due to neural pathways in the brain!" I get it. That was my inclination at first while I was thinking about this too. Please hear me out!
Our First Person Perspective Exists
This may seem like a no brainer, but I am saying more than just our first person perspective exists.
I am saying that the image in your mind when you observe The Starry Night exists in the form that you observe it.
This is the entire point of my argument, so I will say it again:
When you observe The Starry Night, the image that you are perceiving exists in the form that you are perceiving it.
How do we know the 'image' exists in the form that we are observing it? Because there it is. Look at it.
Sure, that image is most certainly dependent upon neural pathways in your brain. No doubt. But if we look inside the brain we don't see that image, and the image exists. You cannot point at any spot in the universe that looks like the 'screen' that you observe when you look at the world.
Spelling Out The Argument
Here is the argument spelled out:
1. The image that we 'see' when we observe the world exists.
2. The image does not exist in the natural world.
3. Therefore, there is a component of our existence that exists outside of the natural world.
Note: This part of us that exists outside of the natural world is directly tied to the natural world via brains and sensory input.
Pretty much, dualism.
Discussion
Remember how I brought up whether or not it would be possible to tell whether or not a computer is conscious or self aware? We can't tell, because self consciousness, the images we observe from the seat of our first person perspective, the thoughts we think in our minds, and the 'screens' (Again, see the blog post entitle "Screens" for my definition of screens) we generate do not exist in the natural world in the form that they exist in our minds.
Our 'screens' never observe screens.
Again I'll say it. We can't tell whether or not a computer is conscious because we can't point at consciousness. Any test that we could use to figure this out would probably disqualify humans too.
Conclusion
Our evidence for the part of our existence that exists outside of the natural world is better than our evidence for the existence of the natural world itself. This is because our evidence for the existence of the natural world is dependent upon our first person perspective. We can't observe the natural world without screens.
Our brains certainly could be purely natural collections of cells. If that were the case, we would be able to observe the entirety of human existence in the natural world. The simple fact, however, is that we cannot observe the entirety of human existence in the natural world, because we cannot point out screens.
Therefore, humans are unique, combinatorial entities which are comprised of parts that are in and outside of the natural world. The part that is outside of the natural world seems to be dependent upon the natural part to observe the natural world, although I don't really know how we would test this to obtain convincing results. Our evidence for the part that is outside of the physical world is better than our evidence for the natural part, because our evidence for the natural part is exhibited to our conscious state in the form of screens.
Further Thought
Some readers may be familiar with Dr. William Lane Criag's favorite argument for God's existence, the cosmological argument. If you are not familiar with his particular spin on the argument, watch Dr. Criag's opening statement in this video: http://www.youtube.com/watch?v=7xcgjtps5ks.
Dr. Craig argues that a reasonable culprit for the agent which gave the universe its beginning is "an unembodied mind."
Before considering my own argument for the existence of souls, I found Dr. Craig's argument problematic. Why would we assume that something that is a part of our existence be a prime suspect for whatever agent generated physics and space-time? That mysterious agent would more probably NOT be something that we are familiar with, as opposed to something that we are familiar with.
However, if we think that souls exist outside of nature, which are at the same time tied to nature, Dr. Craig's argument starts to make more sense. It would certainly offer an explanation for the soul-body dualist existence we seem to be experiencing.
What could be responsible for the origin of 'minds' which exist outside of the natural world, create the natural world, and then tie the two realms together? Why not another mind which is outside of space-time and has the ability to create? Minds are not subject to the various frailties present in naturalistic candidates for the existence of the universe.
Based on my argument, we also need an explanation for the existence of screens. Because natural things do not appear to be able to create supernatural things, such as screens, it makes more sense to think that something supernatural created screens.
Maybe I'm a theist. Maybe I think God created the universe and people. Maybe it makes sense that humans are created in the image of God, in that a part of them is a mind which exists outside of the natural world.
Maybe.
Thanks for reading.
