Esotericism or Esoterism is a term with two basic meanings. In the dictionary sense of the term, it signifies the holding of esoteric opinions, and derives from the Greek (esoterikos), a compound of (eso): “within”, thus “pertaining to the more inward”, mystic. Its antonym is exoteric.
In the scholarly literature, the term designates a series of historically related religious currents including Gnosticism, Hermetism, magic, astrology, alchemy, Rosicrucianism, the Christian Theosophy of Jacob Bohme and his followers, Illuminism, Mesmerism, Swedenborgianism, Spiritualism, and the theosophical currents associated with Helena Blavatsky and her followers.
There are competing views regarding the common traits uniting these currents, none of which involve “inwardness”, mystery or secrecy as a crucial trait.
Esoteric knowledge, in the dictionary (non-scholarly) sense, is thus that which is available only to a narrow circle of “enlightened”, “initiated”, or specially educated people. Esoteric items may be known as esoterica. In contrast, exoteric knowledge is knowledge that is well-known or public; or perceived as informally canonic in society at large.
In Western, English-speaking societies today, the term “esotericism” is not necessarily used in the sense of mystical knowledge or practice, but rather informally to mean any perception or knowledge that is difficult to understand or remember, such as theoretical physics, or that pertains to the minutiae of a particular discipline, such as “esoteric” baseball statistics.
Origins
Plato, in his dialogue Alcibiades (circa 390 BC), uses the expression ta eso meaning «the inner things», and in his dialogue Theaetetus (circa 360 BC) he uses ta ekso meaning «the outside things». The probable first appearance of the Greek adjective esoterikos is in Lucian of Samosata’s “The Auction of Lives”, (also called “The Auction of the Philosophical Schools”), written around AD 166.
The term esoteric first appeared in English in the 1701 History of Philosophy by Thomas Stanley, in his description of the mystery-school of Pythagoras; the Pythagoreans were divided into “exoteric”, (under training}, and “esoteric” (admitted into the “inner” circle).
Connotations
Among the competing understandings of what unites the various currents designated by “Esotericism” in the scholarly sense, perhaps the most influential has been propsed by Antoine Faivre. His definition is based on the presence in these currents of four essential traits: a theory of correspondences, the conviction that nature is a living entity, the need for mediating elements (such as symbols or visions) in order to access spiritual knowledge, and a sense of personal transmutation when arriving at this knowledge. To this are added two less crucial traits. Esotericism sometimes suggests an additional element of initiation. Finally, esotericists frequently suggest that there is a concordance between different religious traditions. It should, however, be emphasied that Faivre’s definition is one of several divergent understandings of the most appropriate use of the term.
History
Since esotericism is not a single tradition but a vast array of often unrelated figures and movements, there is no single historical thread underlying them all. The developments that one might wish to emphasize in drawing up a history of esotericism furthremore depends on whether esotericism in the dictionary (non-scholarly) or the scholarly sense is intended.
Several historically attested religions emphasize secret or hidden knowledge, and are thus esoteric in the dictionary sense, without necessarily being esoteric movements in the scholarly sense of the word. Thus, the Roman Empire had several mystery religions which emphasized initiation. Some saw Christianity, with its ritual of baptism, as a mystery religion. None of these are “esoteric” in the scholarly sense. The terms “Gnosticism” and “Gnosis” refer to a family of religious movements which claimed to possess secret knowledge (gnosis). Another important movement from the ancient world was Hermeticism or Hermetism.
The Ismaili Muslims also stress a distinction between the inner and the outer. It is believed that spiritual salvation is attained by receiving the ‘Nur’ (light) through the esoteric, that is, spiritual search for enlightenment.
Esoteric movements in the scholarly sense have roots in Antiquity and the Middle Ages. A major phase in the development of esotericism begins in the Renaissance, partly as the result of various attempts to revive such earlier movements. During the Italian Renaissance, for example, translators such as Ficino and Pico della Mirandola turned their attention to the classical literature of neo-Platonism, and what was thought to be the pre-Mosaic tradition of Hermeticism. Other pursuits of Antiquity that enetered into the mix od esoteric speculation were astrology and alchemy. Beside such revived currents from late Antiquity, a second major source of esoteric speculation is the kabbalah, which was lifted out of its Jewish context and adapted to a Christian framework by people such as Johannes Reuchlin.
In the early 17th century, esotericism is represented by currents such as Rosicrucianism. A century later, esoteric ideas entered various strands of Freemasonry. In the 19th century, esotericism is represented e.g. by a notable French wave of occultism. The major exponent of esotericism in the latter part of the 19th century is the Theosophy of H. P. Blavatsky. In the 20th century, Theosophy was reformulated by Annie Besant, C. W. Leadbeater, Alice Bailey, Rudolf Steiner and many others.
Theosophy is also considered a major influence on the many current varieties of esotericism in metaphysical organizations, “Ascended Master Activities“, and within the New Age milieu. Anthroposophy, a synthesis of Western esoteric traditions and Theosophy founded by Rudolf Steiner in the early part of the 20th century, stimulated developments in education, agriculture, and medicine. Yet another notable esoteric strain stems from the teachings of G. I. Gurdjieff and P. D. Ouspensky.
