Occult

The occult (from Latin occultus 'hidden, secret') is a category of esoteric or supernatural beliefs and practices which generally fall outside the scope of organized religion and science, encompassing phenomena involving a 'hidden' or 'secret' agency, such as magic and mysticism. It can also refer to paranormal ideas such as extra-sensory perception and parapsychology.

The term occult sciences was used in 16th-century Europe to refer to astrology, alchemy, and natural magic. The term occultism emerged in 19th-century France, among figures such as Antoine Court de Gébelin. It came to be associated with various French esoteric groups connected to Éliphas Lévi and Papus, and in 1875 was introduced into the English language by the esotericist Helena Blavatsky.

Throughout the 20th century, the term 'occult' was used idiosyncratically by a range of different authors. By the 21st century the term 'occultism' was commonly employed –including by academic scholars in the field of Western esotericism studies– to refer to a range of esoteric currents that developed in the mid-19th century and their descendants. Occultism is thus often used to categorise such esoteric traditions as Qabalah, Spiritualism, Theosophy, Anthroposophy, Wicca, the Hermetic Order of the Golden Dawn, New Age, Thelema and the left-hand path and right-hand path.

While Rosicrucianism is not directly 'occult', various Christian Rosicrucian societies have also engaged in esoteric study and are historically adjacent; for example, the Societas Rosicruciana in Anglia and its members influenced the foundation of the Hermetic Order of the Golden Dawn.

Use of the term as a nominalized adjective ('the occult') has developed especially since the late twentieth century. In that same period, occult and culture were combined to form the neologism occulture.

The occult (from the Latin word occultus; lit. 'clandestine', 'hidden', 'secret') is "knowledge of the hidden". In common usage, occult refers to "knowledge of the paranormal", as opposed to "knowledge of the measurable", usually referred to as science. The terms esoteric and arcane can also be used to describe the occult, in addition to their meanings unrelated to the supernatural. The term occult sciences was used in the 16th century to refer to astrology, alchemy, and natural magic.

The earliest known usage of the term occultism is in the French language, as l'occultisme. In this form it appears in A. de Lestrange's article that was published in Dictionnaire des mots nouveaux ("Dictionary of new words") by Jean-Baptiste Richard de Radonvilliers [fr] in 1842. However, it was not related, at this point, to the notion of Ésotérisme chrétien, as has been claimed by Hanegraaff, but to describe a political "system of occulticity" that was directed against priests and aristocrats.

In 1853, the Freemasonic author Jean-Marie Ragon had already used occultisme in his popular work Maçonnerie occulte, relating it to earlier practices that, since the Renaissance, had been termed "occult sciences" or "occult philosophy", but also to the recent socialist teachings of Charles Fourier. The French esotericist Éliphas Lévi then used the term in his influential book on ritual magic, Dogme et rituel de la haute magie, first published in 1856. Lévi was familiar with that work and might have borrowed the term from there. In any case, Lévi also claimed to be a representative of an older tradition of occult science or occult philosophy. It was from his usage of the term occultisme that it gained wider usage; according to Faivre, Lévi was "the principal exponent of esotericism in Europe and the United States" at that time. The term occultism emerged in 19th-century France, where it came to be associated with various French esoteric groups connected to Éliphas Lévi and Papus.
