I do not agree with the many who claim it is impossible to answer the question of what the quantum field is. This field which could be named by a philosophical term, “Transcendental Field” as a thing in itself. On the contrary, it is very easy to come to that answer because there are two rather developed and well-known methods for doing so.
The first is scientific (sensory) and it enables observance of the field’s behavior, i.e. the behavior of its particles and energy systems from the outside. From those behaviors, which always have the meaning of consequence, the conclusion is reached that before they appear, within particles and energy systems must exist the abilities of such behaviors, which, working from the inside, as the main cause (force), force particles and energy systems to behave in such ways.
The other method is that man as a thing by himself, being naught else but an energy system, i.e. one of the highly developed organizations of movement and work of that very field’s particles, and by non-sensory observation of himself directly finds within himself what abilities are in question, thereby discovering an answer to the question, what that field is in itself as a thing in and of itself.
This second method of observation and cognition of the universal quantum field as a thing in and of itself is a sure one, simply because it is about man’s psychological abilities and actions that can be performed only if their performer exists. It (the performer) is always the universal quantum field because it is the only one that exists. It is the same when we speak about the human body, which also does not exist, but rather only the parts and particles of the universal quantum field that build the human body. It unambiguously means that when man examines himself as a thing by himself and finds out inside himself all those psychological abilities and actions he performs, he discovers that those actions are not performed by himself, man, but by the universal quantum field parts and particles that the man is made of since they are the only ones that exist. So man by examining himself within himself as a thing in and of himself actually examines the universal quantum field as the thing in and of itself.
Please note, while applying these two observation methods, especially the second one, it is most important to determine correctly what is the most essential to learn about that (quantum/transcendental) field during its sensory and non-sensory observation in order to be able to present its correct description.
Please note too, that it would be wrong if man would, while examining his human psyche, think that what his psyche is, is also the same as what the universal quantum field psyche is because the human psyche the way it is today developed by the evolution of the universal quantum field psyche, so that today it is something completely different from the universal quantum field psyche. In the same fashion, the human body is something different from universal quantum field physics, from which the human body developed by evolution.
That is why it is necessary for the cognition and comprehension of the human psyche to remember to pay attention only to that which must be common to both the human psyche and the universal quantum field psyche; it is necessary to pay attention to that which could not be changed by the evolution of that field, to that which always remains the same.
What always stays unchanged and the same is, of course, the physical and psychological abilities that the universal quantum field must possess in order to be able to bestir itself, then evolve, and at the end become all that which the energetic/material world is today: a particle, an atom, a planet, a cell, a plant, an animal, a man, a stone, an electronic computer and so on and so forth.
