Astrology

Astrology
From Wikipedia, the free encyclopedia
Astrology is a group of systems, traditions, and beliefs which hold that the relative positions of celestial bodies and related details can provide information about personality, human affairs and other "earthly" matters. A practitioner of astrology is called an astrologer. Astrologers believe that the movements and positions of celestial bodies either directly influence life on Earth or correspond to events experienced on a human scale.[1] Modern astrologers define astrology as a symbolic language,[2][3][4] an art form, or a form of divination.[5][6] Despite differences in definitions, a common assumption of astrologers is that celestial placements can aid in the interpretation of past and present events, and in the prediction of the future.
Astrology is generally considered a pseudoscience or superstition by the scientific community, which cites a lack of statistically significant astrological predictions, while psychology explains much of the continued faith in astrology as a matter of cognitive biases.[7][8][9][10] In 2006 the U.S. National Science Board published a statement which said it considers belief in ten survey items, astrology among them, to be "pseudoscientific".[11]
Numerous traditions and applications employing astrological concepts have arisen since its earliest recorded beginnings in the 3rd millennium BC. Astrology has played an important role in the shaping of culture, early astronomy, the Vedas,[12] and various disciplines throughout history. In fact, astrology and astronomy were often indistinguishable before the modern era, with the desire for predictive and divinatory knowledge one of the motivating factors for astronomical observation. Astronomy began to diverge from astrology after a period of gradual separation from the Renaissance up until the 18th century. Eventually, astronomy distinguished itself as the empirical study of astronomical objects and phenomena, without regard to the terrestrial implications of astrology.
The word "astrology" comes from the Latin term astrologia ("astronomy"),[13] which in turn derives from the Greek noun αστρολογία: ἄστρον, astron ("constellation" or "star") and -λογία, -logia ("the study of").
Historical traditions
Throughout its long history, astrology has come to prominence in many regions and undergone developments and change. There are many astrological traditions that are historically important, but which have largely fallen out of use. Astrologers still retain an interest in them and regard them as an important resource. Historically significant traditions of astrology include Arab and Persian astrology (Medieval, Near East); Babylonian astrology (Ancient, Near East); Egyptian astrology; Hellenistic astrology (Classical antiquity); Hindu astrology and Mayan astrology.
Esoteric traditions

Many mystic or esoteric traditions have links to astrology. In some cases, such as Kabbalah, this involves participants incorporating elements of astrology into their own traditions. In other cases, many astrologers have incorporated other traditions into their own practice of astrology, and astrology has been incorporated into those traditions. Esoteric traditions include, but are not limited to, alchemy, chiromancy, Kabbalistic astrology, medical astrology, numerology, Rosicrucian or "Rose Cross", and Tarot divination.
Historically, alchemy in the Western World was particularly allied and intertwined with traditional Babylonian-Greek style astrology; in numerous ways they were built to complement each other in the search for occult or hidden knowledge.[17] Astrology has used the concept of the four classical elements of alchemy from antiquity up until the present day. Traditionally, each of the seven planets in the solar system known to the ancients was associated with, held dominion over, and "ruled" a certain metal.[18]
Horoscopic astrology
Main article: Horoscopic astrology
Horoscopic astrology is a system that some claim to have developed in the Mediterranean region and specifically Hellenistic Egypt around the late 2nd or early 1st century BC.[19] However, horoscopic astrology has been practiced in India since ancient times, and Vedic astrology is the oldest surviving form of horoscopic astrology in the world.[12] The tradition deals with two-dimensional diagrams of the heavens, or horoscopes, created for specific moments in time. The diagram is then used to interpret the inherent meaning underlying the alignment of celestial bodies at that moment based on a specific set of rules and guidelines. A horoscope was calculated normally for the moment of an individual's birth, or at the beginning of an enterprise or event, because the alignments of the heavens at that moment were thought to determine the nature of the subject in question. One of the defining characteristics of this form of astrology that makes it distinct from other traditions is the computation of the degree of the Eastern horizon rising against the backdrop of the ecliptic at the specific moment under examination, otherwise known as the ascendant. Horoscopic astrology is the most influential and widespread form of astrology in Africa, India, Europe and the Middle East. Medieval and most modern Western traditions of astrology have Hellenistic origins.

Central to horoscopic astrology and its branches is the calculation of the horoscope or astrological chart. This two-dimensional diagrammatic representation shows the celestial bodies' apparent positions in the heavens from the vantage of a location on Earth at a given time and place. The horoscope is also divided into twelve different celestial houses which govern different areas of life. Calculations performed in casting a horoscope involve arithmetic and simple geometry which serve to locate the apparent position of heavenly bodies on desired dates and times based on astronomical tables. In ancient Hellenistic astrology the ascendant demarcated the first celestial house of a horoscope. The word for the ascendant in Greek was ὡροσκόπος (hōroskopos) from which horoscope derives. In modern times, the word has come to refer to the astrological chart as a whole.
Branches
Traditions of horoscopic astrology can be divided into four branches that are each directed towards specific subjects or purposes. Often these branches use a unique set of techniques, or a different application of the core principles of the system to a different area. Many other subsets and applications of astrology are derived from these four fundamental branches.
Natal astrology is the study of a person's natal chart to gain information about the individual and their life experience. Katarchic astrology includes both electional and event astrology. The former uses astrology to determine the most auspicious moment to begin an enterprise or undertaking, and the latter to understand everything about an event from the time at which it took place. Horary astrology is used to answer a specific question by studying the chart of the moment the question is posed to an astrologer. Mundane or world astrology is the application of astrology to world events, including weather, earthquakes, and the rise and fall of empires or religions. This includes the Astrological Ages, such as the Age of Aquarius, Age of Pisces, and so on. Each age is about 2,150 years in length, and many people use these massive ages to characterize and describe major historical ages, as well as current developments in the world.
History

Many believe that the origins of much of the astrological doctrine and method that would later develop in Asia, Europe, and the Middle East are found among the ancient Babylonians and their system of celestial omens that began to be compiled around the middle of the 2nd millennium BC.[20] They believe this system of celestial omens later spread, either directly or indirectly through the Babylonians and Assyrians, to other areas such as the Middle East, and Greece, where it merged with pre-existing indigenous forms of astrology.[21] Thus, Babylonian astrology migrated to Greece, initially as early as the middle of the 4th century BC, and then around the late 2nd or early 1st century BC, after the Alexandrian conquests, this Babylonian astrology was mixed with the Egyptian tradition of decanic astrology to create horoscopic astrology. This new form of astrology, which appears to have originated in Alexandrian Egypt, spread across the ancient world into Europe, the Middle East, and India with varying degrees of influence.
Before the modern era

The differentiation between astronomy and astrology varied from place to place; they were strongly linked in ancient India,[22] ancient Babylonia and medieval Europe, but separated to an extent in the Hellenistic world. The first semantic distinction between astrology and astronomy was probably given by Isidore of Seville[23] (see astrology and astronomy).
The pattern of astronomical knowledge gained from astrological endeavors has been historically repeated across numerous cultures, from ancient India through the classical Maya civilization to medieval Europe. Given this historical contribution, astrology has been called a protoscience along with disciplines such as alchemy.
Astrology was not without criticism before the modern era; it was often challenged by Hellenistic skeptics, church authorities, and medieval Muslim astronomers, such as Al-Farabi (Alpharabius), Ibn al-Haytham (Alhazen), Abū Rayhān al-Bīrūnī, Avicenna and Averroes. Their reasons for refuting astrology were often due to both scientific (the methods used by astrologers being conjectural rather than empirical) and religious (conflicts with orthodox Islamic scholars) reasons.[24] Ibn Qayyim Al-Jawziyya (1292–1350), in his Miftah Dar al-SaCadah, used empirical arguments in astronomy in order to refute astrology and divination.[25]
Many prominent thinkers, philosophers and scientists, such as Galen, Paracelsus, Girolamo Cardan, Nicolaus Copernicus, Taqi al-Din, Tycho Brahe, Galileo Galilei, Johannes Kepler, Carl Jung and others, practiced or significantly contributed to astrology.[26][27]
Modern approaches
Several innovations have occurred in astrological practice in modern times.
Western
Main article: Western astrology
During the middle of the 20th century, Alfred Witte and, following him, Reinhold Ebertin pioneered the use of midpoints (see Midpoint (astrology)) in horoscopic analysis. From the 1930s to the 1980s, astrologers including Dane Rudhyar, Liz Greene and Stephen Arroyo pioneered the use of astrology for psychological analysis, with some following the lead of psychologists like Carl Jung. In the 1930s, Don Neroman developed and popularized in Europe a form of Locational Astrology under the name of "Astrogeography". In the 1970s, American astrologer Jim Lewis developed and popularized a different approach under the name of Astrocartography. Both methods purport to identify varying life conditions through differences in location.
Vedic (Hindu astrology)
Main article: Vedic astrology
Indian astrology uses a different zodiac than Western astrology and is a branch of Vedic science.[28][29] In India, there is a long-established widespread belief in astrology, and it is commonly used for daily life, foremost with regard to marriages, and secondarily with regard to career and electional and karmic astrology.[30][31] In the 1960s, H.R. Seshadri Iyer, introduced a system including the concepts of yogi and avayogi. It generated interest with research oriented astrologers in the West. From the early 1990s, Indian vedic astrologer and author, V.K. Choudhry has created and developed the Systems' Approach for Interpreting Horoscopes, a simplified system of Jyotish (predictive astrology)[32] The system, also known as "SA", helps those who are trying to learn Jyotisha. The late K.S. Krishnamurti developed the Krishnamurti Paddhati system based on the analysis of the stars (nakshatras), by sub-dividing the stars in the ratio of the dasha of the concerned planets. The system is also known as "KP" and "sub theory". In 2001, Indian scientists and politicians debated and critiqued a proposal to use state money to fund research into Vedic astrology.[33]
Effects on world culture
Main article: Cultural influence of astrology
Astrology has had a profound influence over the past few thousand years on Western and Eastern cultures. In the Middle Ages, when the educated of the time believed in astrology, the system of heavenly spheres and bodies was believed to reflect on the system of knowledge and the world itself below. Belief in astrology holds firm today in many parts of the world: in one poll, 31% of Americans expressed a belief in astrology and, according to another study, 39% considered it scientific.[34][35]
Astrology has had an influence on both language and literature. For example, influenza, from medieval Latin influentia meaning influence, was so named because doctors once believed epidemics to be caused by unfavorable planetary and stellar influences.[36] The word "disaster" comes from the Italian disastro, derived from the negative prefix dis- and from Latin aster "star", thus meaning "ill-starred".[37] Adjectives "lunatic" (Luna/Moon), "mercurial" (Mercury), "venereal" (Venus), "martial" (Mars), "jovial" (Jupiter/Jove), and "saturnine" (Saturn) are all old words used to describe personal qualities said to resemble or be highly influenced by the astrological characteristics of the planet, some of which are derived from the attributes of the ancient Roman gods they are named after. In literature, many writers, notably Geoffrey Chaucer[38][39][40] and William Shakespeare,[41][42] used astrological symbolism to add subtlety and nuance to the description of their characters' motivation(s). More recently, Michael Ward has proposed that C.S. Lewis imbued his Chronicles of Narnia with the characteristics and symbols of the seven heavens. Often, an understanding of astrological symbolism is needed to fully appreciate such literature.
Some modern thinkers, notably Carl Jung,[43] believe in astrology's descriptive powers regarding the mind without necessarily subscribing to its predictive claims. In education astrology is reflected in the university education of medieval Europe, which was divided into seven distinct areas, each represented by a particular planet and known as the seven liberal arts. Dante Alighieri speculated that these arts, which grew into the sciences we know today, fitted the same structure as the planets. In music the best known example of astrology's influence is in the orchestral suite called "The Planets" by the British composer Gustav Holst, the framework of which is based upon the astrological symbolism of the planets.
Astrology and science
In the Islamic world astrology was rejected during the turn of the 2nd millenium AD owing to the development of the scientific method and the work of al-Farabi, Alhacen, al-Biruni, Avicenna and Averroes, who made a semantic distinction between astronomy and astrology[44] and helped to render astrology obsolete for Muslims. Muslim views on astrology have generally remained negative.
By the time of Francis Bacon and the scientific revolution, newly emerging scientific disciplines acquired a method of systematic empirical induction based upon experimental observations.[45] At this point, astrology and astronomy began to diverge; astronomy became one of the central sciences, while astrology was increasingly viewed as an occult science or superstition by natural scientists. For example, Christiaan Huygens wrote in his Cosmotheoros: "And as for the Judicial Astrology, that pretends to foretel what is to come, it is such a ridiculous, and oftentimes mischievous Folly, that I do not think it fit to be so much as named."[46] This separation accelerated through the 18th and 19th centuries.[47]
Contemporary scientists, such as Richard Dawkins and Stephen Hawking, regard astrology as unscientific,[48][49] and those such as Andrew Fraknoi of the Astronomical Society of the Pacific have labeled it a pseudoscience.[50] In 1975, the American Humanist Association characterized those who have faith in astrology as doing so "in spite of the fact that there is no verified scientific basis for their beliefs, and indeed that there is strong evidence to the contrary".[51] Astronomer Carl Sagan was unwilling to sign the statement, not because he felt astrology was valid, but because he found the statement's tone authoritarian.[52][53] Sagan stated that he would instead have been willing to sign a statement describing and refuting the principal tenets of astrological belief, which he believed would have been more persuasive and would have produced less controversy than the circulated statement.[54]
Astrophysicist Neil deGrasse Tyson asserted that "astrology was discredited 600 years ago with the birth of modern science. 'To teach it as though you are contributing to the fundamental knowledge of an informed electorate is astonishing in this, the 21st century'. Education should be about knowing how to think, 'And part of knowing how to think is knowing how the laws of nature shape the world around us. Without that knowledge, without that capacity to think, you can easily become a victim of people who seek to take advantage of you'".[55][56]
Although astrology has not been considered a science for some time, it has been the subject of considerable research by astrologers since the beginning of the 20th century. In their study of 20th-century research into natal astrology, Geoffrey Dean, a former astrologer who became critical of the field, and coauthors documented this burgeoning research activity performed primarily within the astrological community.[57]
Researce

Studies have repeatedly failed to demonstrate statistically significant relationships between astrological predictions and operationally defined outcomes.[7][58] Effect size tests of astrology-based hypotheses conclude that the mean accuracy of astrological predictions is no greater than what is expected by chance. For example, when testing for cognitive, behavioral, physical and other variables, one study of 2000 astrological "time twins" born within minutes of each other did not show a celestial influence on human characteristics.[59] It has been suggested that other statistical research is often wrongly seen as evidence for astrology due to uncontrolled artifacts.[60]
Experimental psychologists have suggested that several different effects can contribute to perception of astrological accuracy. One observed tendency is known as the confirmation bias, whereby people who are given a set of multiple predictions tend to remember more of the accurate predictions ("hits") than the inaccurate ones ("misses"). Consequently, people tend to recall the set of predictions as being more accurate than it actually was. A second psychological phenomenon is known as the Forer effect, which refers to a tendency for individuals to give high accuracy ratings to descriptions of their personality that are presented to them as tailored specifically for them, but are in fact vague and general enough to apply to a wide range of people. When astrological predictions turn out to correspond with some phenomena but not with others, the recollected integrity of these predictions may stem in part from confirmation bias. When predictions use vague language, their individualized appearance may be partially attributable to the Forer effect.
The French psychologist and statistician who devoted his life to the attempt to demonstrate the validity of certain fundamentals of astrology, Michel Gauquelin, wrote that he had found correlations between some planetary positions and certain human traits such as vocations.[61] Gauquelin's most widely known concept is the Mars effect, which denotes a correlation between the planet Mars occupying certain positions in the sky more often at the birth of eminent sports champions than at the birth of ordinary people. A similar idea is explored by Richard Tarnas in his work Cosmos and Psyche, in which he examines correspondences between planetary alignments and historically significant events and individuals. Since its original publication in 1955, the Mars effect has been the subject of critical studies and skeptical publications which aim to refute it,[62][63][64] and of studies in fringe journals used to support or expand the original ideas.[65][66] Gauquelin's research has not received mainstream scientific notice.
Obstacles to research

Astrologers have argued that there are significant obstacles in carrying out scientific research into astrology today, including lack of funding,[67][68] lack of background in science and statistics by astrologers,[69] and insufficient expertise in astrology by research scientists and skeptics.[67][68][70] Some astrologers have argued that few practitioners today pursue scientific testing of astrology because they feel that working with clients on a daily basis provides personal validation for their clients.[68][71]
Another argument made by astrologers is that most studies of astrology do not reflect the nature of astrological practice and that the scientific method does not apply to astrology.[72][73] Some astrology proponents argue that the prevailing attitudes and motives of many opponents of astrology introduce conscious or unconscious bias in the formulation of hypotheses to be tested, the conduct of the tests, and the reporting of results.[7][26][51][70][74]
Mechanism

Astrologers have not presented consistent explanations of physical mechanisms underlying astrological beliefs,[75][76] and few modern astrologers believe in a direct causal relationship between heavenly bodies and earthly events.[68] An editorial published by the Astronomical Society of the Pacific reports no evidence for a scientifically defined mechanism by which celestial objects can influence terrestrial affairs.[7] Researchers have posited acausal, purely correlative, relationships between astrological observations and events, such as the theory of synchronicity proposed by Carl Jung.[77] Others have posited a basis in divination.[78] Others have argued that empirical correlations stand on their own epistemologically, and do not need the support of any theory or mechanism.[70] To some observers, these non-mechanistic concepts raise serious questions about the feasibility of validating astrology through scientific testing, and some have gone so far as to reject the applicability of the scientific method to astrology entirely.[70] Some astrologers, on the other hand, believe that astrology is amenable to the scientific method, given sufficiently sophisticated analytical methods, and they cite pilot studies to support this view.[79] Consequently, several astrologers have called for or advocated continuing studies of astrology based on statistical validation.[80]
