In philosophy, eternal oblivion (also referred to as non-existence or nothingness) is the permanent erasure of a person's consciousness upon death. This concept is often associated with skepticism and atheism, and is based in part on the lack of evidence for an afterlife. Consciousness is the basis of subjective experience, agency, self-awareness, and awareness of the surrounding natural world. 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." In the process of brain death, 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. (For more information, see neural correlates of consciousness and disorders of consciousness.) Also, the mind seems to be dependent on the brain, as shown from the various effects of brain damage.〔 Quoting neuroscientist Sam Harris ((video )).〕 As Richard Carrier puts it: "()f destroying parts of a brain destroys parts of a mind, then destroying all the parts of a brain will destroy the whole mind, destroying ''you'' (2005, pp. 151-152)." == Etymology == The English word "oblivion" (late 14c.) comes from the Old French ''oblivion'' (13c.) and directly from the Latin ''oblivionem'', meaning "forgetfulness; a being forgotten", which also comes from the word ''oblivisci'' ("to forget").〔http://www.etymonline.com/index.php?term=oblivion〕 Oblivion itself means "state of being forgotten". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「eternal oblivion」の詳細全文を読む スポンサード リンク
