I am happier with my definition of understanding: Understanding is a psychological state (the state is the result of a process) which allows us to comprehend the relation between concepts. Do you have any problem with that?
I am glad you are happier with your definition, but I have a problem when you don’t seem to understand what a psychological state is, and I’m not clear you understand what the nature of a concept is, or how we attain it. You don’t know of the existence of the human soul, or it’s powers. Understanding is knowing the truth regarding the object contemplated.
STT:
I have three objections here. First, we are not talking about soul here and I don’t think that understanding is a power of soul but brain. We know that people with brain injury lose the power of understanding. Second, I already provide an argument for understanding understanding and I want to know whether you have any objection to that. Third, human being is capable of understanding thoughts which has no relation with objective reality and that is against your argument that you made (bold part).
Whether you agree or not, anytime you talk about psychology or knowledge, you are talking about the soul of man, a rational soul. The brain is the physical medium, or organ that the soul uses to acquire contact with the real objective world, the physical world. You don’t understand what is meant by the body and the soul being co-principles, they constitute the nature of man He is not just an animal, but a rational animal, a homo-sapien
The soul is the animating principle of the body, and makes it what it is, the form. People with brain injury, because the medium has been damaged does not mean the person has lost the power to know, or understand. It is because the soul is extrinsically dependent on the brain in our present mode of existence Repair the brain, and the power becomes active again because it never was really gone. Sleep is a good example, or a coma.
Humans can have thoughts that are called “subjective” vs "objective. The source of subjective thoughts are from the mind of man which may or may not be in contact with the real world such as fiction. There is not fiction without non-fiction. Objective thoughts are thoughts that come from the real physical world. Subjectiive thoughts are only true if they are back up by experience of the real world, not just the mind
STT:
I disagree. We know that we need form to keep knowledge (what we gain as a part of truth), whether it is written in a book or brain. So to my understanding, knowledge is not spiritual. The truth is however objective to my humble opinion is neither physical or spiritual.
If knowledge, rational knowledge is not spiritual, then what is it? Has anyone discovered knowledge as a physical thing, is not knowledge a collection of concepts regarding things experienced? AS I stated, is an idea, or concept demonstratable physically? Is not objective knowledge truth. Truth is not spiritual? Is not reality truth? Is not the world outside our senses real? It exists, and if it exists is it not true? You leave a lot of questions unanswered when answers do exist in conformity with objective reality and not just subjective reasoning.
STT:
This is a huge claim. We as human being have certain capacity to understand things. Whether we are cognitively open to understand spiritual realities is subject of approval. Moreover, you mentioned that we can grasp knowledge only by interacting with physical world, then how we could understand spiritual world without any direct experience of it.
Spiritual realities are not sensed, but understood by the intelligence of man, (using his intellect which is spiritual, a reality you are not familiar with as so many others) We can not physically demonstrate spiritual realities, but we can understand them given enough truth.
STT:
I am sorry but you are making a claim without support. Do you have any argument which show that the capacity to know things in general is a spiritual and not a physical operation?
There is much support if you familiarize yourself with the teachings of St. Thomas, and Aristotle, found in the Summa Theologica, or a shorter version Summa of the Summa, by author Peter Kreeft I Consider how a child comes to know. He through the senses comes into contact with the outside physical world. As he matures he learns beyond what he senses through reasoning and thought, and physical and mental experiences. knowledge starts with our senses, but continues on through our mental life, which is not physical even though as I stated, is dependent on the physical is our present state of existence, which will change at physical death. (man’s intelligence (a spiritual power) is extrinically dependent of the physical as long and the soul is united to the body. The nature of knowledge, and reasoning are clues to the spiritual nature of the soul, the power to know, and to will. It makes for the distinct difference between animals and humans
STT:
I have no idea what intellect as a spiritual power is. I don’t understand how such a cooperation between brain and soul could lead to understanding. To me understanding understanding is logically impossible unless you could show that my argument is wrong. For now you are just claiming an idea without any support.
I have much support as I mentioned, from the Catholic Christian Church and it’s teachers. I don’t expect you to understand since this information is not sufficiently known by you. Follow through with my suggestions
