PhilosophyPhilosophy (love of wisdom in ancient Greek) is a systematic study of general and fundamental questions concerning topics like existence, reason, knowledge, values, mind, and language. It is a rational and critical inquiry that reflects on its own methods and assumptions. Historically, many of the individual sciences, like physics and psychology, formed part of philosophy. But they are considered separate academic disciplines in the modern sense of the term.
SupernaturalSupernatural refers to phenomena or entities that are beyond the laws of nature. The term is derived from Medieval Latin supernaturalis, from Latin super- (above, beyond, or outside of) + natura (nature). Though the corollary term "nature", has had multiple meanings since the ancient world, the term "supernatural" emerged in the Middle Ages and did not exist in the ancient world. The supernatural is featured in folklore and religious contexts, but can also feature as an explanation in more secular contexts, as in the cases of superstitions or belief in the paranormal.
DemonA demon is a malevolent supernatural entity. Historically, belief in demons, or stories about demons, occurs in religion, occultism, literature, fiction, mythology, and folklore; as well as in media such as comics, video games, movies, and television series. Belief in demons probably goes back to the Paleolithic age, stemming from humanity's fear of the unknown, the strange and the horrific.
SpiritismSpiritism (spiritisme; espiritismo), spiritist doctrine, Kardecism or Kardecist spiritism is a spiritualistic and reincarnationist doctrine established in France in the mid-19th century by the author and educator Allan Kardec (pseudonym of Hippolyte Léon Denizard Rivail). It explains, from a Christian perspective, the cycle by which a spirit supposedly returns to material existence after the death of the old body in which it dwelled, as well as the evolution it undergoes during this process.
SoulIn many religious and philosophical traditions, the soul is the spiritual essence of a person, which includes one's identity, personality, and memories, an immaterial aspect or essence of a living being that is believed to be able to survive physical death. The concept of the soul is generally applied to humans, though it can also be applied to other living or even non-living entities, as in animism. The Modern English noun soul is derived from Old English sāwol, sāwel.
