Rational Culture

Rational Culture is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Rational Culture rather than just read about it. In short: Rational Culture (In Portuguese: Cultura Racional) is a Brazilian UFO religion derived from Umbanda, founded in 1935 in the city of Rio de Janeiro by the medium Manuel Jacinto Coelho. Rational Culture is based on a series of books called Universo em Desencanto, a work that addresses a wide range of topics including cosmology, metaphysics, ecology, linguistics, theology, UFOs, and flying saucers.

Key takeaways

  • Rational Culture belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Rational Culture to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Rational Culture from memory before moving on to harder problems.

Reference excerpt

Rational Culture (In Portuguese: Cultura Racional) is a Brazilian UFO religion derived from Umbanda, founded in 1935 in the city of Rio de Janeiro by the medium Manuel Jacinto Coelho. Rational Culture is based on a series of books called Universo em Desencanto, a work that addresses a wide range of topics including cosmology, metaphysics, ecology, linguistics, theology, UFOs, and flying saucers.

Origins Rational Culture emerged on October 4, 1935, at the "Tenda Espírita Francisco de Assis" in Rio de Janeiro, Rua Lopez da Cruz, Méier. During the early decades of the 20th century, persecution of Afro-Brazilian religions increased, with practitioners of these religious segments being pursued and monitored by the police, especially between 1930 and 1945. To escape this persecution and be accepted by society, especially the urban middle class, some Afro-Brazilian religions underwent a process of "de-Africanization" and whitening, in which they sought to differentiate themselves from the so-called "lower spiritism," viewed by this society as backward and uncultured, while also constructing a "rational legitimacy." For this purpose, a group known as the "Intellectuals of Umbanda" worked intensively to provide Umbanda with a doctrinal basis and written knowledge, thereby distinguishing it from the practices of "lower spiritism."

Doctrine Rational Culture emphatically presents the idea that its teachings should be found only in its books and that reading them is the path to "salvation," described in its writings as "Rational Immunization," with no need for methods other than sequential reading of the books.

Religiosity Similar to how the author of Rational Culture distinguishes between "spiritism," dividing it into true and false, the same is done with the term "religion," differentiating it in his work between: true religion and false religion, or religion from above and religion from below. Also, Rational Culture initially denies its religious nature, claiming to be just transcendental knowledge.

Astral Planes According to Rational Culture, the world is divided into four planes: the Rational World, Higher Astral, Lower Astral, and Terrestrial Astral.

Rational World Inhabited by rational beings who have always existed in a rational state and readers of Universo em Desencanto, invisible and on other planets. Its inhabitants would be composed of Rational Energy, a pure, clean, and perfect energy. Located above the Higher Astral.

Higher Astral Inhabited by beings who were unable to fully develop their reasoning, who manifest themselves as flying saucers. The Higher Astral plane, located above the Sun, above electric and magnetic energies, is formed by inhabitants generated by "Mediating Energy."

Lower Astral Inhabited by beings who did not possess "rational conduct."

Terrestrial Astral Inhabited by orishas, "the people of the ground and the people of the air."

Religions Rational Culture recognizes seven main religions (Animism, Brahmanism, Buddhism, Islam, Judaism, Spiritism, and Christianity) responsible for the "confused evolution" and domestication of humanity. The founders of these religions would not be Buddha, Jehovah, or Jesus Christ, but rather beings inhabiting the lower astral.

Spiritism Rational Culture discusses Spiritism in two ways: true spiritism and false spiritism. According to Rational Culture, true spiritism ceased its activities in 1935 and denies the legitimacy of spiritist mediums from that point onwards.

Umbanda Although not recognized by Rational Culture's doctrine: once originating from Umbanda, Rational Culture continued as a branch of it, albeit with a new appearance and altered language, but with the same practices and customs, characterized by what became known among cult members as the "little room," where mediums incorporated entities and provided consultations for people, both members and non-members. These "little rooms" existed in various locations throughout the country, serving as gathering points for followers. It adopts the color of Umbanda's attire (white) and the greeting to eshus used in it. It recognizes orishas as "the people of the ground and the people of the air," inhabitants of the Terrestrial Astral.

Practices

Healing Followers of Rational Culture practice healing through the use of herbs, oils, incense, candles, symbolic objects, reading the books, and chanting to summon entities from the Terrestrial Astral.

Palmistry Followers of Rational Culture practice palmistry, the art of reading hands.

History After the publication of the book "Universo em Desencanto" in the mid-1930s, the religious movement continued in the following decades, having changed its headquarters from Méier to Jacarepaguá, then to Belford Roxo, where the Palácio da Cultura Racional was built. In the 1970s, Rational Culture moved to its current headquarters in Nova Iguaçu, where it remains today. During this period, the religious movement began to be frequented by some artists, including musician Tim Maia, who brought significant visibility to the cult, leading it to its peak. During his time with Rational Culture, the singer recorded two albums that would later become critically acclaimed hits, both titled "Tim Maia Racional". In 2011, Editora Abril released a third unreleased album recorded by the singer in 1976. After leaving the cult, the singer stated:

I joined this cult, which promised to prepare me to communicate with extraterrestrial beings. [...] When I got there, I saw that it was Umbanda, Candomblé, lower spiritism. Jackson do Pandeiro was another artist connected to Rational Culture between 1973 and 1978, recording songs in tribute to the group, such as "Luz do Saber," recorded in 1978. The founder of the cult, Manuel Jacinto Coelho, died in 1991, and since then, Rational Culture has been led by one of his daughters.

Worked examples

Example 1 — a first encounter with Rational Culture

Start with the simplest possible case. Write down what Rational Culture claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Rational Culture before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Rational Culture ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Rational Culture

In research
Rational Culture appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Rational Culture in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Rational Culture is common in secondary-school and first-year university syllabi. It links to neighbouring topics New religious movements established in the 1930s, Pseudoscience, Religion in Brazil, so understanding it makes those chapters shorter.
In everyday life
Look for Rational Culture outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
