Kardecist spiritism in the context of "Positivist"

Positivism is a philosophical school that holds that all genuine knowledge is either true by definition or positive – meaning a posteriori facts derived by reason and logic from sensory experience. Other ways of knowing, such as intuition, introspection, or religious faith, are rejected or considered meaningless.

Although the positivist approach has been a recurrent theme in the history of Western thought, modern positivism was first articulated in the early 19th century by Auguste Comte. His school of sociological positivism holds that society, like the physical world, operates according to scientific laws. After Comte, positivist schools arose in logic, psychology, economics, historiography, and other fields of thought. Generally, positivists attempted to introduce scientific methods to their respective fields. Since the turn of the 20th century, positivism, although still popular, has declined under criticism within the social sciences by antipositivists and critical theorists, among others, for its alleged scientism, reductionism, overgeneralizations, and methodological limitations. Positivism also exerted an unusual influence on Kardecism.

In folklore, a ghost is the soul or spirit of a dead person or non-human animal that is believed by some people to be able to appear to the living. In ghostlore, descriptions of ghosts vary widely, from an invisible presence to translucent or barely visible wispy shapes to realistic, lifelike forms. The deliberate attempt to contact the spirit of a deceased person is known as necromancy, or in spiritism as a séance. Other terms associated with it are apparition, haunt, haint, phantom, poltergeist, shade, specter, spirit, spook, wraith, demon, and ghoul.

The belief in the existence of an afterlife, as well as manifestations of the spirits of the dead, is widespread, dating back to animism or ancestor worship in pre-literate cultures. Certain religious practices—funeral rites, exorcisms, and some practices of spiritualism and ritual magic—are specifically designed to rest the spirits of the dead. Ghosts are generally described as solitary, human-like essences, though stories of ghostly armies and the ghosts of animals other than humans have also been recounted. They are believed to haunt particular locations, objects, or people they were associated with in life. According to a 2009 study by the Pew Research Center, 18% of Americans say they have seen a ghost.

Western esotericism and the arts surveys documented intersections between Western esotericism—notably Hermeticism, Christian Kabbalah, Alchemy, and Astrology—and the visual arts, literature, and the performing arts from the late Middle Ages to the present. Scholarship highlights recurring vectors: Renaissance and early modern image–text programmes (emblems, alchemical series, Kabbalistic diagrams) that formalised "operative images"; encyclopedic displays and diagrams in early modern erudition; nineteenth-century Spirit photography and related "psychic" image technologies; fin de siècle milieux linking occult orders with salon culture; early twentieth-century abstraction tied to Theosophy/Anthroposophy; ritual poetics on stage and in experimental film; and later artist-authored Tarot and neo-alchemical process art.

Aby Warburg's reading of the Palazzo Schifanoia frescoes in Ferrara established a foundational model for interpreting astrological programs in Renaissance art, while Barbara Obrist documented the late-medieval shift toward serial illustration and diagrammatic representation in alchemical manuscripts. Early modern encyclopedic projects—epitomized by Athanasius Kircher—wove hieroglyphs, cosmology, and spectacular display into ambitious image-systems that influenced the period's visual culture. In parallel, historians of science and craft have emphasized how chymistry's "wider worlds" intersected with literature, theatre, and the visual arts. Classic studies have traced how esoteric metaphysics and "spiritual" aesthetics contributed to early abstraction (e.g., Wassily Kandinsky and Hilma af Klint), while recent scholarship reassesses the role of Spiritualism/Spiritism within abstract art and Surrealism's image-making and poetics.

Hippolyte Léon Denizard Rivail ([ʁivaj]; 3 October 1804 – 31 March 1869), known by the pen name of Allan Kardec (French: [kaʁdɛk]), was a French educator, translator, and writer. He is the author of the five books known as the Spiritist Codification, and the founder of Spiritism.

Santería (Spanish pronunciation: [san.te.ˈɾi.a]), also known as Regla de Ocha, Regla Lucumí, or Lucumí, is an African diaspora religion that developed in Cuba during the late 19th century. It arose amid a process of syncretism between the traditional Yoruba religion of West Africa, Catholicism, and Spiritism. There is no central authority in control of Santería and much diversity exists among practitioners, who are known as creyentes ('believers').

Santería teaches the existence of a transcendent creator divinity, Olodumare, under whom are spirits known as oricha. Typically deriving their names and attributes from traditional Yoruba deities, these oricha are equated with Roman Catholic saints and associated with various myths. Each human is deemed to have a personal link to a particular oricha who influences their personality. Olodumare is believed to be the ultimate source of aché, a supernatural force permeating the universe that can be manipulated through ritual actions. Practitioners venerate the oricha at altars, either in the home or in the ilé (house-temple), which is run by a santero (priest) or santera (priestess). Membership of the ilé requires initiation. Offerings to the oricha include fruit, liquor, flowers and sacrificed animals. A central ritual is the toque de santo, in which practitioners drum, sing, and dance to encourage an oricha to possess one of their members and thus communicate with them. Several forms of divination are used, including Ifá, to decipher messages from the oricha. Offerings are also given to the spirits of the dead, with some practitioners identifying as spirit mediums. Healing rituals and the preparation of herbal remedies and talismans also play a prominent role.

A séance or seance (/ˈseɪ.ɑːns/; French: [seɑ̃s]) is an attempt to communicate with spirits. The word séance comes from the French word for "session", from the Old French seoir, "to sit". In French, the word's meaning is quite general and mundane: one may, for example, speak of "une séance de cinéma" (lit. 'a movie session'). In English, however, the word came to be used specifically for a meeting of people who are gathered to receive messages from ghosts or to listen to a spirit medium discourse with or relay messages from spirits. In modern English usage, participants need not be seated while engaged in a séance.

Fictionalised conversations between the deceased appeared in Dialogues of the Dead by George, First Baron Lyttelton, published in England in 1760. Among the notable spirits quoted in this volume are Peter the Great, Pericles, a "North-American Savage", William Penn, and Christina, Queen of Sweden. The popularity of séances grew dramatically with the founding of the religion of Spiritualism in the mid-nineteenth century. Perhaps the best-known series of séances conducted at that time were those of Mary Todd Lincoln, who, grieving the loss of her son, organized Spiritualist séances in the White House, which were attended by her husband, President Abraham Lincoln, and other prominent members of society. The 1887 Seybert Commission report marred the credibility of Spiritualism at the height of its popularity by publishing exposures of fraud and showmanship among secular séance leaders. Modern séances continue to be a part of the religious services of Spiritualist, Spiritist, and Espiritismo churches today, where a greater emphasis is placed on spiritual values versus showmanship.

Mediumship is the practice of purportedly mediating communication between familiar spirits or spirits of the dead and living human beings. Practitioners are known as "mediums" or "spirit mediums". There are different types of mediumship or spirit channelling, including séance tables, trance, and ouija. The practice is associated with spiritualism and spiritism. A similar New Age practice is known as channeling.

Belief in psychic ability is widespread despite the absence of empirical evidence for its existence. Scientific researchers have attempted to ascertain the validity of claims of mediumship for more than one hundred years and have consistently failed to confirm them. As late as 2005, an experiment undertaken by the British Psychological Society reaffirmed that test subjects who self-identified as mediums demonstrated no mediumistic ability.
