Preamble
This article seems to be an impossible task. I want to make the argument that nothing exists besides you, dear reader. The extreme in egocentricity.
But, you might interject, I am reading it, so there must be somebody there who wrote it. But have you ever had a vivid dream, in which you communicated with a person that – at that time in the dream – was very real to you?
Only after you woke up, and before you forgot all about that dream, did you realize that this person only existed in your imagination.
The dilemma is that, as you are reading this, you might be dreaming and the existence of I, yours truly, is just your imagination.
And the dilemma continues – for me!
I am writing these lines, and I am aware that I exist, but I do not know if there is ever anybody out there who will read my words. Sure, I know that you exist; I have met some of you in person, but this might also be just in my imagination.
To summarize our dilemma, here is I, the author of these lines, not knowing if there is an audience outside of my imagination, and then there is you, dear reader, who does not know if there is an author outside of your imagination, or if you just made up the author and the article.
Now, if this is the case, there is no point in writing this piece, as there is nobody to read it. I could say that it can work as a reminder, should I get lost in the appearances of this world, that there are others interacting with me.
But then what about you, reading this? The only way my argument would make sense is if you yourself wrote this – or had the idea about this subject, and you invented this very writer to write this article to remind yourself at some point how the universe really works.
Hmmm… yes, this might work, so let’s get started!
As I was contemplating life, the universe, and everything (again!), Schrödinger’s cat hit me. Not literally, but in the form of thoughts like “Will everything around me, and what I think is important, continue to exist when I am not a member of this realm any longer?”
My train of thought was jump-started by an article I read recently that claimed there now is scientific evidence that objective reality does not exist. I have entertained this line of thinking for a while, but coming to it from the area of spirituality or metaphysics – not physics.
Mr. L. Ron Hubbard introduced me to the concept of individual reality, which can vary greatly between different entities, and a type of ‘objective’ reality which would be a reality with which we are in agreement. Later I encountered A Course in Miracles, which can be interpreted as telling us that everything we perceive is an illusion – or at least could be.
That reminded me that in my very early emotionally involved discussions with my father, we often had come to the conclusion that we can neither prove nor disprove the existence of God.

Extrapolating from there, I had realized early on that perceiving something with our senses is no proof of anything. Imagining a blue elephant does not make it more or less real than seeing one with my eyes open, because if I can imagine a blue elephant, I can also imagine seeing a blue elephant. Seeing, really seeing, things in lucid dreams, convinced me of that. As real as it felt being able to fly in my dream, that reality turned out to be an imagination after I woke up.
To understand my train of thought better, we have to look at quantum physics a little bit more – no, it is actually not that difficult to understand as it is made out to be. Currently, the consensus is that quantum physics applies only to very small particles, like electrons, protons, and atoms. Here it can be observed that those particles sometimes behave as particles and sometimes as waves. One further element of quantum physics is the Heisenberg Uncertainty Principle, which teaches us that for a given particle, both its location and speed cannot be precisely known.
This, by the way, was the finding that broke classical physics in the early 1900s. Up to that point, scientists believed that a theoretically infinitely powerful mind (the Laplace Demon) would be able to know the location and motion of any and all particles in the universe and from that point know the future of a deterministic world. This, fortunately, or unfortunately depending on your point of view, was broken by the Heisenberg Principle, which does not allow the simultaneous knowledge of location and motion of a particle and which rendered the Laplace Demon impossible.
So, now we had an indeterministic world. Particles’ location and motion could only be described in terms of the probability wave function, which tells us the probability of location and motion of a particle. But, you might demur, we can and do measure particles; that is what CERN and all the other particle laboratories do at great costs.
And you are right!
When we observe a particle, the ‘wave function collapses’, meaning that location and motion which had been blurred, suddenly, by the act of observation, become fixed. Notice here that an observer is required for this collapse to occur.
This is hard to swallow for a hardcore materialist, who would not accept that the act of observation would have any special quality. It would require something like consciousness, and that, according to pure materialists, is nothing that exists, as it is something they can not measure.
There is the accepted fact in macro-physics that measurement will have an effect on the thing that is measured. If you have, for example, a glass of water of some, yet to be determined, temperature and you dip in a thermometer which has its own but different temperature, the temperature of the water in the glass probably changes, if only by a very tiny amount, simply by exchanging some heat with the thermometer. If the water is warmer, some of its heat energy will be used to warm up the thermometer, thus cooling the water itself just a tiny bit. Vice versa, if the water is colder than the thermometer, some of the heat of the thermometer will warm up the water just a tad.
But this is fundamentally different than the concept that simply the act of observation by a conscious being will affect the measurement! We investigate more a question like “does the falling tree in the forest still make a sound if nobody is listening.”
For the materialist, there is no question – certainly, it makes a sound! But we can not leave it at that because the realm of quantum physics and its reach into the macro-cosmos is not something a materialist would be an expert in.
Let us now look at the problem by combining the ideas of the collapse of the wave function and the influence of a measurement on the result of that measurement. We start with the hypothesis that the collapse of the wave function is also occurring in the macro-cosmos. This would require that the wave function is not collapsed when nobody is looking, which would, therefore, require that there is no sound from falling trees in the unobserved forest.
But as soon as we have an observer, the wave function collapses, and we have the crashing of the falling tree.
The obvious problem is what happens when there are two observers? This could invalidate the whole hypothesis, as the wave function could not be collapsed for one person and not for another.
But what if there is no other? Humbug, you might exclaim, I see all those other observers, and they report or tell me what goes on in the forest!
Or don’t you?
Basic philosophy teaches us that there is no way to prove that the other people or observers are in fact there. The expression ‘in fact’ would require an absolute reality, existing independent and separate from me – the only observer that I am completely certain about based on René Descartes’ “cogito, ergo sum” (I think, therefore I am).
It is pure faith that anything exists, beyond the certainty of my own existence. There is no possible proof for the thinking and existence of another entity, simply because I perceive this other entity through my senses and they are – or at least could be – just created in my mind. Think of the very real person you saw in your last dream.
Just last night I had a very vivid dream that my car had been towed from the front of the building that belonged to the company I had my first job with. It seemed totally normal that the Jeep that I had for the last several years in the Los Angeles area had been parked in front of a building in Frankfurt, Germany, some forty years ago. It was also of no concern to me that my sister was with me, who now lives in the Northern part of Germany, and it was not at all strange that there were big trenches in the floor next to the elevator so that I had to use a door into the elevator from the other side of the elevator shaft. All that was completely reasonable and did not make me pause to notice how illogical all this was. Important was only my concern about how I would prove that this was my car and how to pay the fees of the impound yard.
I am aware of the awkward situation I am putting myself into by writing these lines – I am addressing another person that does not exist, or at least whose existence I could not prove. So, I might be talking to myself.
