The horoscope visually expresses the set of relationships for the time and place of the chosen event. These relationships are between the seven 'planets', signifying tendencies such as war and love; the twelve signs of the zodiac; and the twelve houses. Each planet is in a particular sign and a particular house at the chosen time, when observed from the chosen place, creating two kinds of relationship. A third kind is the aspect of each planet to every other planet, where for example two planets 120° apart (in 'trine') are in a harmonious relationship, but two planets 90° apart ('square') are in a conflicted relationship. Together these relationships and their interpretations supposedly form "...the language of the heavens speaking to learned men."[

Theological viewpoints
Ancient
St. Augustine (354430) believed that the determinism of astrology conflicted with the Christian doctrines of man's free will and responsibility, and God not being the cause of evil, but he also grounded his opposition philosophically, citing the failure of astrology to explain twins who behave differently although conceived at the same moment and born at approximately the same time.
Medieval
Some of the practices of astrology were contested on theological grounds by medieval Muslim astronomers such as Al-Farabi
Abu Nasr Muhammad Al-Farabi ( fa, ابونصر محمد فارابی), ( ar, أبو نصر محمد الفارابي), known in the West as Alpharabius; (c. 872 – between 14 December, 950 and 12 January, 951)PDF version was a renowned early Isl ...

(Alhazen) and Avicenna. They said that the methods of astrologers conflicted with orthodox religious views of Islamic scholars, by suggesting that the Will of God can be known and predicted. For example, Avicenna's 'Refutation against astrology', ''Risāla fī ibṭāl aḥkām al-nojūm'', argues against the practice of astrology while supporting the principle that planets may act as agents of divine causation. Avicenna considered that the movement of the planets influenced life on earth in a deterministic way, but argued against the possibility of determining the exact influence of the stars. Essentially, Avicenna did not deny the core dogma of astrology, but denied our ability to understand it to the extent that precise and fatalistic predictions could be made from it. Ibn Qayyim Al-Jawziyya
Shams al-Dīn Abū ʿAbd Allāh Muḥammad ibn Abī Bakr ibn Ayyūb al-Zurʿī l-Dimashqī l-Ḥanbalī (29 January 1292–15 September 1350 CE / 691 AH–751 AH), commonly known as Ibn Qayyim al-Jawziyya ("The son of the principal of he school ...

Confirmation bias is a form of cognitive bias, a psychological factor that contributes to belief in astrology. Astrology believers tend to selectively remember predictions that turn out to be true, and do not remember those that turn out false. Another, separate, form of confirmation bias also plays a role, where believers often fail to distinguish between messages that demonstrate special ability and those that do not. Thus there are two distinct forms of confirmation bias that are under study with respect to astrological belief.

Karl Popper, astrology is a pseudoscience. Popper regarded astrology as "pseudo-empirical" in that "it appeals to observation and experiment," but "nevertheless does not come up to scientific standards."[
* The relevant piece is also in ] In contrast to scientific disciplines, astrology has not responded to falsification through experiment.
In contrast to Popper, the philosopher Thomas Kuhn

argued that it was not lack of falsifiability that makes astrology unscientific, but rather that the process and concepts of astrology are non-empirical. Kuhn thought that, though astrologers had, historically, made predictions that categorically failed, this in itself does not make astrology unscientific, nor do attempts by astrologers to explain away failures by claiming that creating a horoscope is very difficult. Rather, in Kuhn's eyes, astrology is not science because it was always more akin to medieval medicine; astrologers followed a sequence of rules and guidelines for a seemingly necessary field with known shortcomings, but they did no research because the fields are not amenable to research, and so "they had no puzzles to solve and therefore no science to practise." While an astronomer could correct for failure, an astrologer could not. An astrologer could only explain away failure but could not revise the astrological hypothesis
A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous obse ...

Paul Richard Thagard (; born 1950) is a Canadian philosopher who specializes in cognitive science, philosophy of mind, and the philosophy of science and medicine. Thagard is a professor emeritus of philosophy at the University of Waterloo. He i ...
asserts that astrology cannot be regarded as falsified in this sense until it has been replaced with a successor. In the case of predicting behaviour, psychology is the alternative. To Thagard a further criterion of demarcation of science from pseudoscience is that the state-of-the-art must progress and that the community of researchers should be attempting to compare the current theory to alternatives, and not be "selective in considering confirmations and disconfirmations." Progress is defined here as explaining new phenomena and solving existing problems, yet astrology has failed to progress having only changed little in nearly 2000 years. To Thagard, astrologers are acting as though engaged in normal science Normal(s) or The Normal(s) may refer to:

believing that the foundations of astrology were well established despite the "many unsolved problems", and in the face of better alternative theories (psychology). For these reasons Thagard views astrology as pseudoscience.
For the philosopher Edward W. James, astrology is irrational not because of the numerous problems with mechanisms and falsification due to experiments, but because an analysis of the astrological literature shows that it is infused with fallacious logic and poor reasoning.

In 1955, the astrologer and psychologist Michel Gauquelin stated that though he had failed to find evidence that supported indicators like zodiacal signs and planetary aspects in astrology, he did find positive correlations between the diurnal positions of some planets and success in professions that astrology traditionally associates with those planets. The best-known of Gauquelin's findings is based on the positions of Mars in the natal chart

They attributed the effect to selective bias on Gauquelin's part, accusing him of attempting to persuade them to add or delete names from their study.
Geoffrey Dean has suggested that the effect may be caused by self-reporting of birth dates by parents rather than any issue with the study by Gauquelin. The suggestion is that a small subset of the parents may have had changed birth times to be consistent with better astrological charts for a related profession. The number of births under astrologically undesirable conditions was also lower, indicating that parents choose dates and times to suit their beliefs. The sample group was taken from a time where belief in astrology was more common. Gauquelin had failed to find the Mars effect in more recent populations, where a nurse or doctor recorded the birth information.[
Dean, a scientist and former astrologer, and psychologist Ivan Kelly conducted a large scale scientific test that involved more than one hundred cognitive, ]behavioural

pooled 40 studies that involved 700 astrologers and over 1,000 birth charts. Ten of the tests—which involved 300 participants—had the astrologers pick the correct chart interpretation out of a number of others that were not the astrologically correct chart interpretation (usually three to five others). When date and other obvious clues were removed, no significant results suggested there was any preferred chart.
Lack of mechanisms and consistency
Testing the validity of astrology can be difficult, because there is no consensus amongst astrologers as to what astrology is or what it can predict. Most professional astrologers are paid to predict the future or describe a person's personality and life, but most horoscopes only make vague untestable statements that can apply to almost anyone.
Many astrologers claim that astrology is scientific, while some have proposed conventional causal agents such as electromagnetism

Western astrology has taken the earth's axial precession (also called precession of the equinoxes) into account since Ptolemy's '' Almagest'', so the "first point of Aries", the start of the astrological year, continually moves against the background of the stars. The tropical zodiac has no connection to the stars, and as long as no claims are made that the constellations themselves are in the associated sign, astrologers avoid the concept that precession seemingly moves the constellations. Charpak and Broch, noting this, referred to astrology based on the tropical zodiac as being "...empty boxes that have nothing to do with anything and are devoid of any consistency or correspondence with the stars."[ Sole use of the tropical zodiac is inconsistent with references made, by the same astrologers, to the Age of Aquarius, which depends on when the vernal point enters the constellation of Aquarius.]
Astrologers usually have only a small knowledge of astronomy, and often do not take into account basic principles—such as the precession of the equinoxes, which changes the position of the sun with time. They commented on the example of Élizabeth Teissier
Élizabeth Teissier, née Germaine Élizabeth Hanselmann (born 6 January 1938) is a French astrologer and former model and actress. Between 1975 and 1976, she created a daily horoscope on French television channel Antenne 2, and in 1981, she lau ...
, who claimed that, "The sun ends up in the same place in the sky on the same date each year", as the basis for claims that two people with the same birthday, but a number of years apart, should be under the same planetary influence. Charpak and Broch noted that, "There is a difference of about twenty-two thousand miles between Earth's location on any specific date in two successive years", and that thus they should not be under the same influence according to astrology. Over a 40-year period there would be a difference greater than 780,000 miles.

In fact, de Wohl's predictions were so inaccurate that he was soon labelled a "complete charlatan", and later evidence showed that Hitler considered astrology "complete nonsense". After John Hinckley's attempted assassination of US President Ronald Reagan, first lady Nancy Reagan commissioned astrologer Joan Quigley to act as the secret White House astrologer.

He found that most astrology-believers did not claim it was a scientific explanation with predictive power. Instead, those superficially involved, knowing "next to nothing" about astrology's 'mechanics', read newspaper astrology columns, and could benefit from "tension-management of anxieties" and "a cognitive belief-system that transcends science." Those at the second level usually had their horoscopes cast and sought advice and predictions. They were much younger than those at the first level, and could benefit from knowledge of the language of astrology and the resulting ability to belong to a coherent and exclusive group. Those at the third level were highly involved and usually cast horoscopes for themselves.
