Do you believe in life after death essay

System 1, on the other hand, is intuitive, instinctual and automatic. These capabilities regularly develop in humans, regardless of where they are born. They are survival mechanisms. System 1 bestows us with an innate revulsion of rotting meat, allows us to speak our native language without thinking about it and gives babies the ability to recognise parents and distinguish between living and nonliving objects.

It makes us prone to looking for patterns to better understand our world, and to seek meaning for seemingly random events like natural disasters or the death of loved ones. In addition to helping us navigate the dangers of the world and find a mate, some scholars think that System 1 also enabled religions to evolve and perpetuate. Millennia ago, that tendency probably helped us avoid concealed danger, such as lions crouched in the grass or venomous snakes concealed in the bush. But it also made us vulnerable to inferring the existence of invisible agents — whether they took the form of a benevolent god watching over us, an unappeased ancestor punishing us with a drought or a monster lurking in the shadows.

Similarly, System 1 encourages us to see things dualistically, meaning we have trouble thinking of the mind and body as a single unit. This tendency emerges quite early: young children, regardless of their cultural background, are inclined to believe that they have an immortal soul — that their essence or personhood existed somewhere prior to their birth, and will always continue to exist.

This disposition easily assimilates into many existing religions, or — with a bit of creativity — lends itself to devising original constructs.

Atheists must fight against all of that cultural and evolutionary baggage. Our minds crave purpose and explanation.

Azerbaijani Muslims pray at the end of Ramadan Getty Images. On the other hand, science — the system of choice that many atheists and non-believers look to for understanding the natural world — is not an easy cognitive pill to swallow. Science is about correcting System 1 biases, McCauley says.

We must accept that the Earth spins, even though we never experience that sensation for ourselves. We must embrace the idea that evolution is utterly indifferent and that there is no ultimate design or purpose to the Universe, even though our intuition tells us differently. We also find it difficult to admit that we are wrong, to resist our own biases and to accept that truth as we understand it is ever changing as new empirical data are gathered and tested — all staples of science.

Life After Death

Even without organised religion, they believe that some greater being or life force guides the world. Additionally, non-believers often lean on what could be interpreted as religious proxies — sports teams, yoga, professional institutions, Mother Nature and more — to guide their values in life. As a testament to this, witchcraft is gaining popularity in the US, and paganism seems to be the fastest growing religion in the UK. Religious experiences for non-believers can also manifest in other, more bizarre ways. Anthropologist Ryan Hornbeck, also at the Thrive Center for Human Development, found evidence that the World of Warcraft is assuming spiritual importance for some players in China, for example.

The threat of an all-powerful God or gods watching for anyone who steps out of line likely helped to keep order in ancient societies. And again, insecurity and suffering in a population may play a role here, by helping to encourage religions with stricter moral codes. In a recent analysis of religious belief systems of nearly traditional societies from around the world, Joseph Bulbulia at the Victoria University of Wellington, New Zealand and his colleagues found that those places with harsher weather or that are more prone to natural disasters were more likely to develop moralising gods.

Helpful neighbours could mean the difference between life and death. In this context, religion evolved as a valuable public utility. Across cultures, people who are more religious also tend to have more children than people who are not. For all of these reasons — psychological, neurological, historical, cultural and logistical — experts guess that religion will probably never go away. If not, it would no longer be with us. And even if we lose sight of the Christian, Muslim and Hindu gods and all the rest, superstitions and spiritualism will almost certainly still prevail. We might want to say that I am the sum of all the points, yet the assertion that a human being is his or her entire worldline, from birth to death, does not appear to be consistent with the general consensus that every event along a worldline has a singular existence that cannot be preferred over any other event on that worldline.

The theory of relativity tells us that all of the laws of physics are the same for every inertial observer. If we live in a fully relational, relativistic universe, we simply cannot prefer observations made in the inertial frame of reference of one observer over observations made in the inertial frame of reference of any other observer, no matter where they may be "located" in space-time. An apparent consequence of this fact is that for one observer your tenth birthday occurs before your eleventh birthday, while for another spatially separated observer your eleventh birthday occurs before your tenth!

The cosmos is a very strange place indeed! Classic interpretations imply that each individual exists as discrete human consciousness in the billions of discrete events located at every point along that individual's worldline. Some physicists describe this by saying that there are many "now's"; others say there are billions of approximate "isomorphs" of "me"; many claim there are billions of other worlds in which various versions of "me" co-exist; etc.

It seems reasonable to conclude that modern physics tells us that if time exists, literally billions of discrete, very real, versions of each of us occupy space-time! This may seem like science fiction, yet surveys of theoretical physicists and cosmologists confirm that most believe we must adopt some form of many-worlds, multiple existence, theory. Remember, this is current accepted thought, and not just speculative ideas. If there really are an infinite number of parallel universes which we do not believe is true , or if there is a "me" that exists on my worldline for every event in my physical life, then there is no singular physical "me".

Rather there are billions of isolated "me's" either lying along my worldline, or stuck somewhere in totally isolated universes. If the scientists are correct, it would seem to be impossible to find meaning and value for a singular "me" in the collective existence of each of the billions of instances of individual consciousness, no single one of which is the "me" who can live a meaningful life. All of the popular interpretations of relativistic and quantum theories lead us to the same conclusion, if you do not have a singular permanent existence, your life has no meaning and your choices make no difference to "you", simply because there is no single physical "you" that exists before or after physical death please remember, we believe that life has meaning and value.

There is a third possibility, that the intuitive feeling human beings have that their physical past cannot change or be lost is based on some real, yet unknown, physical model of our universe. As we have said, virtually everyone is certain that if they are eleven years old now they have already experienced their tenth year of life, and that nothing can take from them the past experience of being ten years old.

Is There Life After Death? Jewish Thinking on the Afterlife

The intuitive feeling is very strong that our physical life makes a positive or negative contribution to human existence, and that our physical life is a permanent part of the physical universe. Perhaps there is some single physical consciousness that incorporates all of the events along our worldline, and that preserves our physical past, present, and future. We cannot rule out this possibility, if for no other reason than the fact that it is theoretically impossible to prove a negative. In other words, we might be able to prove that physical consciousness after death exists in the universe by observing it, but we can never prove that physical consciousness, or some other form of existential meaning, does not exist after death because we have not observed it we discuss this limitation in some detail in our other book.

Do You Believe In Life After Death?

Indeed, the very fact that human beings exist in our universe argues strongly for existential meaning and purpose. If we have a physical existence that has existential meaning then the billions of people who intuitively believe that every day, every moment, of their lives has purpose and value are absolutely right.

I believe in Reincarnation

Yet if we are to believe that there may be some kind of physical existence that survives physical death, then it would seem that we would need to accept that there is some unique physical consciousness that is "me", that somehow incorporates all of the conscious events of all of my life, and that is somehow not dependent on the physical existence of my biologic body. While current interpretations of popular theories do not rule out the possibility of a perpetual individual physical consciousness, there is no known method that is both rational and realistic i.

Life After Death

Modern theories suggest the possibility that multiple instances of a physical "me" exist in space-time, but they do not tell us how to unite all of those instances into a single physical "me" whose consciousness spans space-time. Indeed, current interpretations of quantum superposition seem to deny the possibility of a "single" reality.

If human beings do not have some kind of singular existence after physical death, we are again faced with the question how life can have meaning to someone who no longer exists. The possibility that we have a permanent physical consciousness would appear to require the existence of a physical consciousness that is not bound to events on a worldline. Yet it seems intuitively true that if consciousness of past events can be lost when memories fade in old age or are damaged when we suffer brain injuries or strokes, then physical consciousness may not have incorporated those past events into a permanent singular "me".

In fact, every night between dreams we lose touch with our past memories as we sleep.

Einstein only briefly addressed physical not non-physical existence when he said "An individual who should survive his physical death is also beyond my comprehension, While I can visualize and accept a "non-physical consciousness" that survives physical death, I am unable to have any confidence in the existence of a singular "physical consciousness" or other form of existential meaning that survives the physical death of a human being.

I may be wrong. Almost every philosopher and scientist, in fact almost all of the billions of human beings who live on this earth, believe that physical life has existential meaning and purpose. Yet our intuition may be telling us that physical life does in fact have existential meaning which has not yet been explained, or at least not satisfactorily explained, by science. In coming out of the dark ages human beings have made enormous intellectual leaps in philosophy and science, so much so that many now believe we understand how life works.

We need to recognize the fact that when future generations look back at twenty-first century science it will seem as primitive to them as alchemy does to us, and they will be rightly amazed at our lack of understanding of our existence. There are glimpses of a possible future e.

Yet at this point these speculative ideas are little more than science fiction, there is no objective reason to believe that any of them will be found to be true.

We have concluded, rightly or wrongly, that no current, or reasonably foreseeable, rational theory provides us with a singular physical consciousness or other existential existence so that after my physical death a physical "me" continues to exist in my "past". We have said that if we do not have a singular physical or non-physical consciousness that continues to exist after physical death, then those who believe in nihilism are probably correct, and some type of "nihilistic" void awaits all of us.
