People in cultures throughout the ages have felt that there is some sort of spiritual essence in humans that goes beyond the physical body and mind. That spiritual essence is usually called the soul. While most agree that people have individual spirits or souls, others believe that your soul is part of a larger, universal soul. Some native tribes feel that even inanimate objects—such as rocks, the wind, or the sun—have souls. The soul also seems to be part of, or related to, a larger spiritual force. That larger force or spirit is usually called God. Some religions say that we are God. Others look at a supreme spiritual force as Mother Nature. Still other groups—like the ancient Greeks and Romans—have many gods for different occasions.
The concept of the soul is different in the Jewish Bible Old Testament than in the Christian New Testament. The Hebrew word for soul occurs some 700 times in the Old Testament, but often it is used as a similar word for person (i.E. "He was a hearty soul."). Some passages imply that the living body is a soul.
The Greek word for soul is used 100 times in the New Testament. That usage is more aligned to the Greek—and the modern—idea of a soul as separate from the body. Almost everyone feels there is "something else" about them besides their body and mind.
For those who believe the soul is a distinct spiritual essence, the question arises as to when a person gets a soul or when the physical body is assigned a soul. Members of many religions believe that a person gains a soul at the moment of conception. This seems like a logical starting point, but it also defines a simple fertilized egg as a human being.
On the other hand, other groups believe that a fetus doesn't become a person or have a soul until birth. This idea also has its validity. Is there some other possible time when the body and soul meet?
It is even possible that a person exists as a spirit before the soul is assigned to a human body, and animal or even an object. If a person's soul only exists within his or her body, then the issue of when the person actually gets the soul is important. On the other hand, if the soul is everywhere and is simply assigned a person's body the timing may not be as relevant.
Since the fate of the soul in many religions depends on the behavior of the person, is it related to the brain? In other words, whether a person is good or bad, believes or doesn't, is controlled by that person's thinking and brain. Whether he or she goes to Heaven then depends on the person's thoughts. In such a situation, it would seem that the soul is related to the brain. Philosophers have speculated on this over the centuries. Holy books give their religion's versions of what the soul is.
I sit on the fence when considering this question, but im veering towards there being an existence of a thing that is beyond the brain that gives us the ability to be aware of thoughts and be conscious sentient beings. However the idea of this essence being able to exist without a brain seems silly as that would disqualify the need for a brain or further a need for a human body etc. I reason that our bodies function in certain ways controlled by our brain some of these functions we are aware of and can control but others are not. This doesnt discount the possibility that a spirit/soul exists as part of ourselves but the likelihood of tgis existing seperate from the brain is silly...I propose that the brain and soul are interdependant on eachother
First of all, I argue against the existence of soul or spirit doesn't means that I have problem with religion kind of stuff. But there are too many scientific investigation that got solid evidence to against the claims of spirit. As most of people who accepted high level education know, our emotion, feeling, thinking are generate by the tissue structure of our brain .
