In order to understand how humans behave on an individual or social level, it is necessary to examine the ways in which their body reacts to the reception of information through the human senses. One might say, the key is hidden in understanding how the human body regulates its functional process in response to the data it receives through the senses of vision, audition, gustation, olfaction and tactition [1].

But that is not enough. It is also essential to take into account the information stored inside the brain as a result of the reception of data, because it can be used as previous data in the process of analysis of the outcome of future actions, decisions, etc., and it is also helpful in formulating the methods through which thoughts that result from the "thinking" process being performed by the brain (or in other words, the process of the interaction of the existing stored groups of data inside the brain with themselves, or the outcomes of the reception of data through senses) are formed.

Physical reactions in the body are caused by the changes in the conditions of the chemicals inside it. Many of these are associated with certain feelings by the brain. The roots of all feelings known to mankind are more than likely easily traced through these processes down to the molecular, or even atomic, level.

Comprehending how our brains work, or how humans behave and act, is only possible through studying the subject on different levels of different nature, looking at the system through different lenses of different magnitude and texture... more than one view is needed.
Every phenomenon related to the subject needs to be broken down into basic steps which are preferably significant on different scales.

[1] Feelings like heat (or lack thereof) and pain are directly controlled by the brain in a sense that the information received by the brain through the sense of touch is almost simultaneously translated into data related to the said feelings, or in other words, subconsciously interpreted by the brain. (Obviously, the feeling of pain in the internal organs follows a different procedure as the sense of touch is not involved. Though, it is still directly, and subconsciously, controlled by the brain.)
