Relationship

When an idea, or a concept, is told (in any way) to a person in a frequent way, and for a long enough period of time, the person will develop a deeper, stronger, interpretation of the subject, and therefore, will believe in it. The brain-washed fanatics of any type of ideology are a prime example of this matter. It also happens in less significant, and more personal cases. If a person hears, sees or reads that they are ugly every week, after a certain period of time, they will believe that they are ugly, no matter how fine and beautiful they look.
The brain evolves, and creates more connections, more paths, and [thus] more networks, within itself.

The reason we, as humans, are capable of learning, the truth behind our fascinating intelligence (which is not, and has never been, even close to perfection in any individual), is brains ability to create more connections, and possibilities, with the help of the already existing neural networks at the moment of starting the process (which may take as short as fractions of a second, and as long as years and decades). The nature of the factors affecting this progress determines the nature of the function of the created network.
It is fair to assume that the pattern for these processes can be also transferred to the infants by their parents, just like the other physical or neural characteristics which are received by the children through them. The level they have progressed to is different in any individual, just as the factors and causes affecting them are, which may result in a stop in the of progress of the networks in a group of individuals, and hence, oppressing the whole network.

This concept is quite easy to express through the language of Mathematics. A system performing the act of iteration (inputs to the system are its outputs) is a suitable choice for a model. However, the system itself is a web of similar systems, which is fed by the output of a similar group of networks. So, the iteration only happens in one direction.
The connections within each system, and the groups of networks, can be determined and modeled using fractal geometry.

NOTE: This is an extreme and specific (yet more obvious) example of the development of behaviour in every individual. It can be easily generalized to cover every naturally progressed neural network in the brain.

The Body...

If you start at a body's surface, and cut and dig deeper and deeper, every little phenomenon and object that you encounter is going to be engaged in performing a materialistic behaviour, whether it is electrical, or chemical, or physical. It is fair to say that no matter how small these systems and elements are, they will still be demonstrating materialistic behaviour which can be quantified. How can another separate body of a different nature exist within this mixture of tightly bonded materialistic parts and systems? How can there be something which is nothing?

One way to look at this misconception about the human nature is to think of the brain as a center of command in the body's "system" (which it basically is). However, it is also reasonable to assume that this center is not keeping in touch with each and every part of body at any given moment. In other words, there are no electrical correspondences going on among the different neural networks connecting the brain with various body parts. It is more like they are in a standby mode. Most of the times, they are at normal state. The increase and decrease in the chemical concentration of the liquids around the neurons causes them to generate electrical signals, and transmit them through the neural networks. As long as the level of the chemicals are at a normal level, their state does not change. It is as if they do not exist.

Feeling the "soul" inside the body can be a natural step in the progression of the human brain. The weightlessness caused by the non-functioning (or malfunctioning) neural networks and connections, which could put the brain in a state of falsely experiencing a mindframe, can be a contributing factor in the development of spirituality and the belief in metaphysical forms, shapes and entities within, and outside the human body throughout the history.

NOTE: Parts of the brain are indeed constantly in "touch" with certain body parts (the parts responsible for subconscious activities within the body), but the main state of the brain does not consciously keep track of, or register, those activities at any given moment. Hence, it is as if they do not exist or happen.

Solid Violence

When he fucked, he actually stayed true to the nature of the word, and delivered an act which truly showcased the appropriate level of aggression and anger which needs to be associated with the term, "fucking".

He fucked to destroy. He fucked to hate. He fucked for revenge. A decent sense of rationality was almost gone.

The longer he had been pushed around to chase women, the meaner he would fuck, eventually when he would get his hands on them. It'd become too addictive for them, so they would have a harder time whenever he told them off.

One of them actually found satisfaction in a rather bizarre way. She found herself growing fonder and fonder of watching him fuck other women with that type of aggression.

Facts...

Change causes motion and motion creates change. There is no system within which no change occurs or perfect stability is achieved.

Hence, a moving system cannot arrive, and stay at a eternally stable level, becoming a system in which the rate of change is zero. Only partial stability is possible.

Therefore, there cannot be any truth to the concepts related to the after life and "the world beyond" proposed by the religious and spiritual sources since, scientifically speaking, order and stability cannot be achieved for an infinite period of time in any part of the universe.

After stability fails, chaos takes over, creating a period of nothingness. The systems would be too sensitive to very negligible changes in the sets of factors influencing them, and thus, creating a frenzy of change and motion, with an extremely fast response to the smallest variation in the sets of the initial conditions. Too Many possibilities, the rate of creation and existence is close to zero.

However, a specific set of the initial conditions set is capable of randomly creating a partially stable state where further creation is possible.

The equations...

The fear of loneliness has always driven humans towards joining different social (or political, cultural, ideological etc. The more specific types have been introduced in varying (increasing, to be exact) rates throughout the history.) groups of different scale and size. This kind of phobia, as any other type of phobia, changes from a minimal level to an extremely high one. Therefore, different people are afraid of being lonely on many different levels. One's fear level could be negligible, and the other's could be substantially dominant over the rest of his phobias. However, there could also be several other cases where the difference between the levels is essentially very small.
Generally, each individual's level has the potential of increasing (or decreasing) to another level if and only if it is influenced (or caused) to change by a new dominant set of changing factors. (A way to influence the neural progress)

This could all be represented by a ratio of two polynomials of degree, and order, n and m (where n is less than m). The coefficients of the n+m terms can be obtained by using a learning algorithm to estimate their accuracy. The bigger problem is the calculation of the exact values of n and m (in other words, finding the more dominant terms (i.e. characteristics) that influence the final value produced by the ratio on different crucial levels). This could be done by estimating these terms, and again, using a learning algorithm suitable for these terms and their own characteristics to correct and change the errors produced during the process.

It is necessary to apply some approximations while doing these calculations. However, respecting the extremely complex nature of each individual element should always be the first consideration.

In order for a process to be logical, a certain pattern, or relationship (which would eventually cause the occurrence of a certain outcome) has to exist for a specific set of initial conditions. That is the more dominant system. However, a less dominant system is also at work with a highly chaotic rate of change, which has the capability of damaging the proficiency of the first system by creating more dominant outcomes (points of extrema) in a highly chaotic way with infinite possible values.

This is perfectly compatible with the idea of multiple variables in a system producing different values (which can become the valuable points of the fucntion, the points from where information about the behaviour of the function can be extracted) in a continuous way, spanning from negative infinity or positive infinity, based on the relationship among the multiple variables and their individual characteristics.
