Mind Or Self?


A more to be come and more to be lost, an incredible journey that resides inside little thought, may be hard to imagine but still a way to define the prescribed journey and what we call “Mind”. A thoughtful but weird imagination where dreams dance, a lavish reality and inside it, what remains is void like space.

Here, in this article there is some unique questions regarding to the  existence of mind as this is not a mind’s concept, but rather a concept of individuality. In our life, we are facing a mind related problem and we are not sure whether mind exists or is a dreadful dream. Still, a lot of confusion here, “self” a concept about thinking and self-existence which needs a correct perception about mind. Generally, we see this absurdity in mind-body problem where mind and body is a subject and they both perform different tasks. For mind, it performs such actions like feeling, pain, emotions, thoughts and for body perspective, atoms, neurons, matter are responsible for the body’s performance.

The mind-body problem is further divided into two sections one is materialism and second one is dualism. In materialism, we are physical object and in dualism we are a part of soul. or it is better to say a soul object, and a part body). But when we go further, we ask ourselves, “Who we are?”, if individually then “What am I?” sometimes call this “personal identity”. But what is personal identity and how we understand it explicitly?

Personal Identity, is way to endeavor the study of beings i.e. persons as most philosophers called this. In personal identity, we have questions like “What am I?”, “What will happen when I die?” “When did I begin?” and much more. These questions raise a big problem while facing a problem of personal identity which then define as “Self” (sometimes, it is related to person or being). Again, self creates a chaos and we are not sure what exactly self is. Is this a void or something that never have it’s own existence? For instance, suppose we have two persons let it be A and B. Somewhere, unfortunately person A dies, then what will be the reaction of person B. For person B, person A dies and there is nothing left. But, what for person A? Is person A feels that reaction as person B feels? Yes, may be but not sure whether this will happen or not.

For person A, he / she dies but when we talk about it’s existence in terms of thoughts then where his / her thoughts become self as there is nothing behind self and there is no “self”, if avoid the existence of “void”. Person B, here experience a death of person B, here experience matters whether pragmatically or have a understanding. But for person A, there is nothing that cherished his elegant way to space and feel he / she dies, but still thoughts exists that are the real cause of the existence of mind and then mind will become one with “self” that mind always is unique and one so as to alive even after death as research claims thoughts never dies just like soul. Well, chaos here at least we are at the verge of technological world where body matters if there is no body then how one would be able to perform such tasks that seems enigma for mind as well as for understanding the concept of dualism that stuck the monism as well (Monism, will discuss in next chapter). So, mind is indispensable whether in a form of soul or in a form of body but we need both the concepts without relying on weird existence as “self is a understanding that never dies with death”.

Article on Mind Or Soul?

A relation between mind or soul? An essence on mind-body and self problem.




# Currently gravity is based on “Albert Einstein’s general theory of relativity”  which is formulated with the Classical Physics.

# Quantum Gravity is generally used to describe the gravitational field and unite all forces in a single force.

# In Quantum Theory, it gives rise to a String Theory.

# String Theory however on the other side try to unify gravity with other fundamental forces such as quantum loop.


GUT (Grand Unified Theory)

# In above diagram, various fields have their won meaning but when come to end “Quantum Gravity” stuck the mind of everyone.

# Standard Model of Physics yet is unable to find the GUT ( Grand Unified Theory) and still facing a problem of “Gravitons” (that is 2-spin massless particles).

# In Kaluza-Klein Theory, five dimensional theory combined with the gravitation and electromagnetism as it generally appears in String Theory.

# There are many ways to define Quantum Gravity such as ‘”Quantum Loop Gravity”, “Time”, String Theory” , Nonrenormalizability of Gravity and many others ways.

# Quantum Gravity is no the end of the ultimate reality as this is still a smaller beginning.


# String Theory is consider to be a point like particles which are replaced by one dimensional objects.

# String Theory is generally used for description of gravity and particle physics.

# String Theory was first studied in late 1960, with the rise of a strong nuclear force.

# Fundamentally objects string theory is closed and open strings model.

# String Theory has also interaction with quantum world i.e. worldlines of point like particles or sometimes called world sheet.

# In String Theory, we are likely to talk about more than four dimensions such as length, height, width and time (which is the fourth dimension).

# In String Theory there are 11 dimensions, Superstring Theory has 10 dimensions and  Bosonic String Theory there are 26 dimensions.

# String Theory is further divided into “Brane” and “Dualities”. In Brane Theory, open strings attached to a pair  known as D-Branes whereas in Dualities, it is of two kind S Duality and T Duality.

# Matrix Theory also provide some useful contribution to the string theory as in physics, matrix model gives us the behavior of set of matrices within the framework of quantum mechanics.

# There are various assumptions for string theory such as Mirror Symmetry, Calabi-Yau Manifold, Bekeinstein- Hawking formula, Quantum Gravity, Anti-de Sitter Space and many other methods for assuming the one of the most challenging concept in nature.

# Reality is what one wants to understand but still criticizes himself  / herself not because reality of ultimate nature is hidden but exists everywhere to create uncertainty.


# Brian Greene born on 9 February 1963. He was a Physicist, Mathematician and String Theorist.

# He is also a co-founder of World Science Festival.

# He has worked on Mirror Symmetry, Calabi-Yau manifolds.

# He is the author of “The Elegant Universe”, “The Fabric of Cosmos”, The Hidden Reality and many more.

# He also appeared on Television series presented by a Nova. Where he talks about universe, space, string theory and many other scientific perceptions.

# He is doing his best for science and hence talk about science, has many seminars and other discussions on science.
