To acquire a thorough comprehension of human nature, with its facets and rules, is a way to discern where you erred.  In doing so, it will be easier for you to end predicaments in your life, subsequently advancing towards a brighter and better future. 

Non-scientifically, in the pre-modern times, human nature then was understood in reference to the formal and final causes.  Such understanding implied the existence of divine interests in human, or the existence of an idea, form or ideals, all of which independently exist among human beings.  However, in the scientific and modern understanding of human nature, it refers to the diverse range of human behaviors that are believed to be invariant and normal for longer periods already and across the various cultural circumstances.          

The actuality of the varied nature among human has always been an intriguing subject of historical debates, especially in the modern times.  Most famous of which is Charles Darwin’s scientific argument that both humans and animal species have no fixed nature.  Prior to this, the equally famous philosopher, Jean Jacques Rousseau, asserted man’s adaptability. 

Beginning in the middle of the 19^th century, concepts underneath the nature of human had been questioned by the likes of Sarte, Hegel, Nietzsche, and Marx.  These names are associated to being postmodernists and structuralists.  Likewise, the concepts were challenged according to views and opinions in terms of behaviorism and determinism, as well as the chemical model in contemporary psychology and psychiatry, in which it tended to elaborate on the idea that humans might be explained as matters in motion, as in similar to the other parts and elements of nature. 

The particular study of human nature has several branches of science being associated to it, which includes sociobiology, sociology, and psychology, with developmental psychology and evolutionary psychology in particular.  Theologians and philosophers in the planet are highly accredited for their studies, works and views with regards to human nature. 

Studying the various factors relating to human nature primarily reveals that the utmost desire of every object and matter is to keep its existence.  It signifies that in every object and matter is the incessant will to exist and to survive. 

This internal force somehow deigns the substance’s shape and defines its comportment and qualities.  There are different combinations and forms of the will to live on, which served as the basic of every substance within this existing world.

For the simple reason that human behaviors are so invariable, philosophers had a really tough time in finding a unique behavior that caught their interests.  Several scientists who were into the study of behaviors used a lesser standard of evidence that deals with human nature.  Some biologists focused on genetic predisposition in search of behavioral patterns.  However, genetic predispositions may be influenced by the surroundings or the environment, therefore, penetrance of genetically affected trait cannot be expected to be 100 percent.  A particular human behavior said to be strongly influence by a genetic predisposition might be relatively considered as an integral aspect of human nature.  Thus, human nature is something that stimulates individuals to act and behave in a definite manner.  

There are many influential schools all throughout the globe that defended several conceptions of the human nature and incorporated such conceptions to other ideas, such as Marxism, Freudianism, and Platonism.

In Platonism, Plato used the examined life he learned from Socrates, and the concept of reason, wherein he built both anthropology and metaphysics around it.  It indicated the notion that an intellectual soul resides within the human heads, and that an appetitive beast dwelled on the genitals and belly.  At one point, Plato’s dualism became immensely influential enough that it hinted itself to Christian theology. 

Meanwhile, for Aristotle, reasoning was not the only thing that was odd in humanity, but what people were meant to attain at her or his best as well.  Aristotle’s statement still proves to be worth considering, however, it should mentioned the part wherein human nature was intended or meant for something or to be something, has declined in popularity most especially in this modern generation.

In conclusion, humans greatly affect the environment, as well as the environment affecting human beings.  Consequently, humans change ceaselessly, not because of being happy or unhappy, but simply because of the awareness of others, making one to have what the other has.  Unlike the other living creatures in the planet, human beings need many, many years to evolve and to mature.  The prevalent fact that human beings are endowed with emotion and intellect only enhances one’s will to live and survive, for willpower is obviously not limited to a precise place or time.  And this is one essential aspect of human nature.
