Before I get going, I must say that this video has horrible background music. Not just bad, but ridiculously annoying.
Non-naturalism is a fairly tough concept to grasp. While naturalism would deny the existence of truth, reality and knowledge, non-naturalism is a form of moral realism where they accept these traits as a part of the human conscience. This human conscience is described in the video as “the only reality,” and the “physical universe is the virtual reality.” They attempt to explain that what exists is solely in the brain of an individual. This is basically going back to the idea of truth being held by the individual, and everything around that person being a result of a “virtual reality.” Very, very comic-humanist based.
I don’t believe that the human conscience can exist or be “truth” without the presence of a physical reality. The non-naturalist will believe that truth, reality, and knowledge are true, but yet don’t have viable reasoning behind why it is true. Just as our minds can use deductive reasoning to decide the best deal at wall mart, so is the case for another. This sale is not representative of a virtual reality, but a universal reality where another human could purchase the same item for that sale price. They are either together as both being real(physical and personal) or not in existence at all(married bachelor). The mind acts as a reaction to the physical world. One cannot deny completely deny naturalism or even non-naturalism, as they both contain aspects that are vital for existence. Together the mind and the physical world work to form reality.
Truth, reality and knowledge are so closely related to one another. They believe that these aspects are inside of us due to a God-force. To state that the knowledge inside of us is simply a result of a God force would be extremely fallacious. How did I learn that George Washington was our first president? It is through study and experience one can learn and form thoughts. If world is based solely on my own perceptions, I would imagine myself being the first president. One would have to deny universally accepted ideas such as math and science to follow this system. Their ideas are too farfetched to even be considered.
In conclusion, while they do make an attempt to explain truth, reality, and knowledge, it is inadequate and ultimately contradicts itself in the end. The physical world must coexist with the mental state. One does not control the other, and they certainly both exist, just as truth, reality and knowledge most definitely are vital aspects of life.
