People are always asking theists why we believe, and usually I would post a large selection of links. But experience has shown that most people, myself included, just want a straight answer and don’t want to have to click tons of links. So this is a replacement response.
I first started leaving atheism when I realized that the metaphysical position of material monism was seriously flawed. My main rejection of gods was mainly based in this idea that if something is not material it does not exist, so when that failed my atheism started falling apart. There are many reasons that materialism is incorrect, from the fact that self-existence is axiomatic but non-physical, to the problem of property dualism in which mind and brain share basically no characteristics, and of course the well documented knowledge that while affecting the brain affects the mind, the opposite is also clearly true. Then as I got further into my rejection I came to realize that the mind is not the only immaterial thing by a long shot, but rather even logic and math are themselves immaterial yet obviously existent with a massive influence on the universe and how it works. Basically if materialism is right then the mind, logic, and math are all things that don’t actually exist, which is obvious nonsense.
Once my metaphysical view was more or less decimated, it was a long and rough journey to find a system which did not have these massive flaws, but also accurately described reality as we know it. It would have been easier just to grab onto any metaphysical system which provided answers, but that’s not how I was raised or educated. What I ended up coming to was a modified, modern version of Plato’s Theory of Forms. There are many good arguments for Forms, perhaps the best being that we can’t have any knowledge of things in a constant state of change. If there is no stable truth, no thing-in-itself, then knowledge is impossible because it would be in a constant state of flux. Yet we are obviously able to attain knowledge, so there must be something stable behind the constantly changing manifestations – the Realm of Forms.
Another good example for Platonism is our ability to recognize identical characteristics in non-identical things. For example, we can draw 10 triangles of different side lengths, different angles of the points, etc. Obviously the 10 triangles are non-identical, or there would simply be 1 triangle drawn 10 times. So how do we recognize 10 non-identical things as, basically, the same thing, in this case a triangle? That a Form of Triangles exists is the best possible explanation, there is the “thing-in-itself” for what triangles are, including having three sides, three points, 2 flips and 3 rotations. We recognize the 10 things as triangles because they partake in the same Form. We can further investigate just one of these characteristics, such as points. Find several pointed objects around you: a pencil, a door, a table, scissors, etc. and so on. All of these things have points, but the points are, obviously, non-identical (obvious because the points don’t even take up the same space and aren’t made out of the same atoms). Yet despite this, we recognize this same characteristic throughout all the objects: pointedness. But can we show pointedness in itself? The individual points are not pointedness themselves, or all other points would partake in that literal, physical point, which is obviously not the case. Again, Forms are the best explanation.
Then there were little things here and there. For example, I always found it suspicious that consciousness leaped forward in the Upper Paleolithic Revolution, despite anatomically modern humans existing for hundreds of thousands of years before that event. Further, the abilities of the mind are what we can call “against nature.” In other words, consciousness is capable of accomplishing things that could not naturally occur. We do not need to wait out sickness because we have manipulated nature to create medication. Architects change the face of nature with their own subjective images, counselors teach those with mental illness how to overcome and redirect these natural, chemical processes with conscious intent, engineers create all sorts of goodies that could never be grown in a garden without consciousness no matter how long we let the system of nature run for. It became obvious that there was something strange about consciousness, that something unnatural could not be solely by natural processes and events. Of course having realizing that Platonism was true, I understood that there was indeed a Form of Consciousness, and I began to ponder if this was somehow worthy of the title “God.”
Another big one, which then fed back into this understanding of Platonism, was the mind-blowing discovery of Life Fields, a concept investigated by Dr. Harold Saxton Burr. In short, Dr. Burr discovered and proved, through a massive number of scientific experiments, that human bodies have “Life Fields” or “L-Fields,” which are like electromagnetic fields but predictive of future states. For example, measuring of the L-Field can predict cancer before there is any sign of cancer, it can predict menstrual cycles, changes in mood, periods of superior and inferior learning, the location of the head/tail/nervous system in an egg, and the list goes on. In other words, Dr. Burr more or less discovered a blueprint for the development and changes of the physical body. He logically went on to theorize this was evidence of a designer, for blueprints require and suggest intentional design. Burr proposed this was God and left it be, arguing against materialism for the remainder of his life. However, Lt. Colonel Dr. Michael A. Aquino, a prominent member of the psychological operations aspect of the U.S. military, showed that platonic Forms explain L-Fields without the need for a standard, creator god. If Platonism is correct there is a Form of the Individual, and if there is a Form of the Individual, which would be outside of space and time, this would easily explain how there would be “future” knowledge to create a blueprint of the physical individual. If you are going to develop cancer in 8 months, the individual Form is already aware of this, and this connection between Form and body is what creates the “Life-Field.”
Eventually this line of thought led me to a type of polytheism, what I call Platonic Polytheism. You see, a Form contains all that which it manifests, for example the Form of Triangles includes the Form of Points, of Sidedness, of the Number 3. Likewise, a Form of Consciousness, which must exist if Platonism is correct, would contain that which it manifests, such as self-awareness, desire, emotion, and so forth. From there it did not take long to connect the dots – an immaterial, timeless, necessary, and self-aware being with intent and personality: that is precisely what a God is. Not an onmi-God of monotheism no, but a God of polytheism. Further, there are more Forms like this than simply consciousness: desire, love, anger, knowledge, the list simply goes on and on, and if the Form of Consciousness is a God, so are these other similar Forms.
