In philosophy, eternal oblivion (also referred to as non-existence or nothingness) is the permanent cessation of one's consciousness upon death. This concept is often associated with religious skepticism and atheism.
According to contemporary scientific theories of consciousness, the brain is the basis of subjective experience, agency, self-awareness, and awareness of the surrounding natural world. When brain death occurs, all brain function permanently ceases. Many people who believe that death is a permanent cessation of consciousness also believe that consciousness is dependent upon the functioning of the brain. Scientific research has discovered that some areas of the brain, like the reticular activating system or the thalamus, appear to be necessary for consciousness, because damage to these structures or their lack of function causes a loss of consciousness.
Through a naturalist analysis of the mind (an approach adopted by many philosophers of mind and neuroscientists), it is regarded as being dependent on the brain, as shown from the various effects of brain damage.
In the Apology of Socrates (written by Plato), after Socrates is sentenced to death, he addresses the court. He ponders the nature of death, and summarizes that there are basically two opinions about it. The first is that it is a migration of the soul or consciousness from this existence into another, and that the souls of all previously deceased people will also be there. This excites Socrates, because he will be able to conduct his dialectic inquiries with all of the great Greek heroes and thinkers of the past. The other opinion about death is that it is oblivion, the complete cessation of consciousness, not only unable to feel but a complete lack of awareness, like a person in a deep, dreamless sleep. Socrates says that even this oblivion does not frighten him very much, because while he would be unaware, he would correspondingly be free from any pain or suffering. Indeed, Socrates says, not even the great King of Persia could say that he ever rested so soundly and peacefully as he did in a dreamless sleep.
Cicero, writing three centuries later in his treatise On Old Age, in the voice of Cato the Elder, similarly discussed the prospects of death, frequently referring to the works of earlier Greek writers. Cicero also concluded that death was either a continuation of consciousness or cessation of it, and that if consciousness continues in some form, there is no reason to fear death; while if it is in fact eternal oblivion, he will be free of all worldly miseries, in which case he should also not be deeply troubled by death.
Similar thoughts about death were expressed by the Roman poet and philosopher Lucretius in his first-century BC didactic poem De rerum natura and by the ancient Greek philosopher Epicurus in his Letter to Menoeceus, in which he writes;
Paraphrasing philosopher Paul Edwards, Keith Augustine and Yonatan I. Fishman note that "the greater the damage to the brain, the greater the corresponding damage to the mind. The natural extrapolation from this pattern is all too clear — obliterate brain functioning altogether, and mental functioning too will cease".
Contemporary atheist scientists Steven Pinker and Sean Carroll assert that death is equivalent to eternal oblivion, as physical theories based on scientific materialism allow for no mechanism to continue consciousness after death.
The term "eternal Oblivion" has been used in international treaties such a in Article II of the Treaty of Westphalia 1648. It has alos been used in municiple legislation such as in the English Indemnity and Oblivion Act 1660, where the phrase used is "perpetual Oblivion" (it appears in several of the articles in the act).
Thomas W. Clark, founder of Center for Naturalism, wrote a paper titled "Death, Nothingness, and Subjectivity" (1994). He critiqued what he saw as a flawed description of eternal oblivion as a "plunge into darkness". When some imagine their deaths (including the non-religious), they project themselves into a future self which experiences an eternal silent darkness. This is wrong, because without consciousness, there is no awareness of space and no basis for time. For Clark, in oblivion there isn't even an absence of experience, as we can only speak of experience when a subjective self exists.
According to neuroscientist Giulio Tononi, consciousness is "all we are and all we have: lose consciousness and, as far as you are concerned, your own self and the entire world dissolve into nothingness."
Algor mortis (Latin: algor—coldness; mortis—of death), the second stage of death, is the change in body temperature post mortem, until the ambient temperature is matched. This is generally a steady decline, although if the ambient temperature is above the body temperature (such as in a hot desert), the change in temperature will be positive, as the (relatively) cooler body acclimates to the warmer environment. External factors can have a significant influence.
The term was first used by Dowler in 1849. The first published measurements of the intervals of temperature after death were done by Dr John Davey in 1839.Consciousness after death
Consciousness after death is a common theme in society and culture in the context of life after death. Scientific research has established that the mind and consciousness are closely connected with the physiological functioning of the brain, the cessation of which defines brain death. However, many believe in some form of life after death, which is a feature of many religions.Dead on arrival
Dead on arrival (DOA), also dead in the field and brought in dead (BID), indicates that a patient was found to be already clinically dead upon the arrival of professional medical assistance, often in the form of first responders such as emergency medical technicians, paramedics, or police.
In some jurisdictions, first responders must consult verbally with a physician before officially pronouncing a patient deceased, but once cardiopulmonary resuscitation is initiated, it must be continued until a physician can pronounce the patient dead.Death
Death is the inevitable, permanent cessation of all biological functions that sustain a living organism. Phenomena which commonly bring about death include aging, predation, malnutrition, disease, suicide, homicide, starvation, dehydration, and accidents or major trauma resulting in terminal injury. In most cases, bodies of living organisms begin to decompose shortly after death.Death – particularly the death of humans – has commonly been considered a sad or unpleasant occasion, due to the affection for the being that has died and the termination of social and familial bonds with the deceased. Other concerns include fear of death, necrophobia, anxiety, sorrow, grief, emotional pain, depression, sympathy, compassion, solitude, or saudade. Many cultures and religions have the idea of an afterlife, and also hold the idea of reward or judgement and punishment for past sin.Death hoax
A death hoax is a deliberate or confused report of someone's death that turns out to be incorrect and murder rumors. In some cases it might be because the person has intentionally faked death.Death messenger
Death messengers, in former times, were those who were dispatched to spread the news that an inhabitant of their city or village had died. They were to wear unadorned black and go door to door with the message, "You are asked to attend the funeral of the departed __________ at (time, date, and place)." This was all they were allowed to say, and were to move on to the next house immediately after uttering the announcement. This tradition persisted in some areas to as late as the mid-19th century.Death rattle
Terminal respiratory secretions (or simply terminal secretions), known colloquially as a death rattle, are sounds often produced by someone who is near death as a result of fluids such as saliva and bronchial secretions accumulating in the throat and upper chest. Those who are dying may lose their ability to swallow and may have increased production of bronchial secretions, resulting in such an accumulation. Usually, two or three days earlier, the symptoms of approaching death can be observed as saliva accumulates in the throat, making it very difficult to take even a spoonful of water. Related symptoms can include shortness of breath and rapid chest movement. While death rattle is a strong indication that someone is near death, it can also be produced by other problems that cause interference with the swallowing reflex, such as brain injuries.It is sometimes misinterpreted as the sound of the person choking to death, or alternatively, that they are gargling.Dignified death
Dignified death is a somewhat elusive concept often related to suicide. One factor that has been cited as a core component of dignified death is maintaining a sense of control. Another view is that a truly dignified death is an extension of a dignified life. There is some concern that assisted suicide does not guarantee a dignified death, since some patients may experience complications such as nausea and vomiting. There is some concern that age discrimination denies the elderly a dignified death.Dysthanasia
In medicine, dysthanasia means "bad death" and is considered a common fault of modern medicine.Dysthanasia occurs when a person who is dying has their biological life extended through technological means without regard to the person's quality of life. Technologies such as an implantable cardioverter defibrillator, artificial ventilation, ventricular assist devices, and extracorporeal membrane oxygenation can extend the dying process.
Dysthanasia is a term generally used when a person is seen to be kept alive artificially in a condition where, otherwise, they cannot survive; sometimes for some sort of ulterior motive. The term was used frequently in the investigation into the death of Formula One driver Ayrton Senna in 1994.Lazarus sign
The Lazarus sign or Lazarus reflex is a reflex movement in brain-dead or brainstem failure patients, which causes them to briefly raise their arms and drop them crossed on their chests (in a position similar to some Egyptian mummies). The phenomenon is named after the Biblical figure Lazarus of Bethany, whom Jesus raised from the dead in the Gospel of John.Megadeath
Megadeath (or megacorpse) is one million human deaths, usually caused by a nuclear explosion. The term was used by scientists and thinkers who strategized likely outcomes of all-out nuclear warfare.Necronym
A necronym (from the Greek words νεκρός, nekros, "dead" and ὄνομα ónoma, "name") is a reference to, or name of, a person who has died. Many cultures have taboos and traditions associated with referring to such a person. These vary from the extreme of never again speaking the person's real name, often using some circumlocution instead, to the opposite extreme of commemorating it incessantly by naming other things or people after the deceased.
For instance, in some cultures it is common for a newborn child to receive the name (a necronym) of a relative who has recently died, while in others to reuse such a name would be considered extremely inappropriate or even forbidden. While this varies from culture to culture, the use of necronyms is quite common.Necrophobia
Necrophobia is a specific phobia which is the irrational fear of dead things (e.g., corpses) as well as things associated with death (e.g., coffins, tombstones, funerals, cemeteries). With all types of emotions, obsession with death becomes evident in both fascination and objectification. In a cultural sense, necrophobia may also be used to mean a fear of the dead by a cultural group, e.g., a belief that the spirits of the dead will return to haunt the living.Symptoms include: shortness of breath, rapid breathing, irregular heartbeat, sweating, dry mouth and shaking, feeling sick and uneasy, psychological instability, and an altogether feeling of dread and trepidation. The sufferer may feel this phobia all the time. The sufferer may also experience this sensation when something triggers the fear, like a close encounter with a dead animal or the funeral of a loved one or friend. The fear may have developed when a person witnessed a death, or was forced to attend a funeral as a child. Some people experience this after viewing frightening media.The fear can manifest itself as a serious condition. Treatment options include medication and therapy.The word necrophobia is derived from the Greek nekros (νεκρός) for "corpse" and the Greek phobos (φόβος) for "fear".Obituary
An obituary (obit for short) is a news article that reports the recent death of a person, typically along with an account of the person's life and information about the upcoming funeral. In large cities and larger newspapers, obituaries are written only for people considered significant. In local newspapers, an obituary may be published for any local resident upon death. A necrology is a register or list of records of the deaths of people related to a particular organization, group or field, which may only contain the sparsest details, or small obituaries. Historical necrologies can be important sources of information.
Two types of paid advertisements are related to obituaries. One, known as a death notice, omits most biographical details and may be a legally required public notice under some circumstances. The other type, a paid memorial advertisement, is usually written by family members or friends, perhaps with assistance from a funeral home. Both types of paid advertisements are usually run as classified advertisements.Outline of death
The following outline is provided as an overview of and topical guide to death:
Death – termination of all biological functions that sustain a living organism.Pallor mortis
Pallor mortis (Latin: pallor "paleness", mortis "of death"), the first stage of death, is an after-death paleness that occurs in those with light/white skin.Post-mortem interval
Post-mortem interval (PMI) is the time that has elapsed since a person has died. If the time in question is not known, a number of medical/scientific techniques are used to determine it. This also can refer to the stage of decomposition of the body.Skeletonization
Skeletonization refers to the final stage of decomposition, during which the last vestiges of the soft tissues of a corpse or carcass have decayed or dried to the point that the skeleton is exposed. By the end of the skeletonization process, all soft tissue will have been eliminated, leaving only disarticulated bones. In a temperate climate, it usually requires three weeks to several years for a body to completely decompose into a skeleton, depending on factors such as temperature, humidity, presence of insects, and submergence in a substrate such as water. In tropical climates, skeletonization can occur in weeks, while in tundra areas, skeletonization may take years or may never occur, if subzero temperatures persist. Natural embalming processes in peat bogs or salt deserts can delay the process indefinitely, sometimes resulting in natural mummification.The rate of skeletonization and the present condition of a corpse or carcass can be used to determine the time of death.After skeletonization, if scavenging animals do not destroy or remove the bones, acids in many fertile soils take about 20 years to completely dissolve the skeleton of mid- to large-size mammals, such as humans, leaving no trace of the organism. In neutral-pH soil or sand, the skeleton can persist for hundreds of years before it finally disintegrates. Alternately, especially in very fine, dry, salty, anoxic, or mildly alkaline soils, bones may undergo fossilization, converting into minerals that may persist indefinitely.
