Time A or Time B?

J.M.E. McTaggart, who in 1908 coined
the terms "A and B-theories of time."

Human beings seem to have an innate tendency to think that what we do not like or cannot explain does not exist. Thus in Hinduism and Buddhism, reality itself is considered an illusion (maya), something that must be discarded to achieve liberation. According to this philosophy, since it is an inseparable part of physical reality, time should also be considered as an illusion. In the Hindu Brahman and the Buddhist Nirvana, time does not exist.

In Western philosophy and science, the idea of ​​time has traditionally been quite different. Until the eighteenth century, nobody put in question the reality of reality. As an inseparable part of reality, time was absolute. In Newtonian mechanics, time plays that role. According to his theory of gravitation, the course of time is independent of the motion of the observer. Hence one can deduce the principle of relativity of classical mechanics: when several bodies are subjected to uniform rectilinear motion (at constant speed) it is impossible to distinguish which one is at rest and which is moving.

Determinism versus freedom (2nd part)

Claude Elwood Shannon

Among the arguments used by deterministic neuroscientists to prove that human freedom does not exist, I’ll mention two:

• Brain injuries and mental disorders affect the mind and self-consciousness in various ways, depending on which part of the brain is affected. In the worst case, self-consciousness can be completely lost. Hence they deduce that self-consciousness is an epiphenomenon that can provide some evolutionary advantages, but at bottom is an illusion without objective reality.
• Moreover, mental states of all kinds (even mystical experiences) can be caused by applying electromagnetic stimuli to different parts of the brain. Hence they deduce that mental states depend only on the electrical state of our neurons, while mystical experiences, whatever their origin, are all hallucinatory. I have discussed this in another article.

The dilemma determinism versus freedom

In one of my mystery novels (El Zahir de Quetzalcoatl) the protagonist must solve three riddles, as in the classic fairy tales. The third puzzle consists of three statements that cannot all be true or false. This enigma is what you might call a trilemma.

C.S.Lewis

A famous trilemma (usually called the 3-L) was formulated by C.S.Lewis to justify the divinity of Christ. Assuming that Christ affirmed his own divinity, Lewis posed the following alternatives: either Christ was a Lunatic, or a Liar, or he was the Lord. Of these three statements, only one can be true, as each one excludes the other two.

On the question of human freedom, whose reality is denied by deterministic philosophy, Brigitte Falkenburg proposes another trilemma, a little different, because in this case any two of the three alternatives can be true, but then the third must be false. This is her trilemma:

Dating the crucifixion of Jesus Christ

During their deportation in Babylon, the Jewish people adopted a lunar Babylonian calendar and took it with them at their return to Palestine. Ordinarily their year consisted of twelve lunar months, but as this made them lose on average eleven days every year against the solar cycle, occasionally it was necessary to introduce an intercalary month, thus some of their years had thirteen months.

At the beginning of our era there was no rigid rule for the proclamation of the intercalated months. Every year the Sanhedrin (the Jewish Supreme Court) decreed whether or not an extra month would be intercalated. For this they used several criteria, first of all that the Passover celebration had to take place after the spring equinox, but if the crop had been very bad and the first fruits, to be offered in that festivity, were not mature, or if the sacrificial lambs had not grown enough, the council could decide to insert a new month, delaying a full cycle the celebration of the Passover.

Jesus of Nazareth: The Infancy Narratives

Pope Benedict XVI

In his book The Spaniard and the seven deadly sins, Fernando Diaz Plaja criticizes what he considers an example of the sin of pride rather common among Spaniards: criticizing a book without having read it. He offers the following example:

Literary judgment is easiest in Spain. I once listened to a radio broadcast where a few writers commented Dr. Zhivago, by Pasternak. The opinions were so hard, sharp and negative, that a lady of the group, with a probably Russian accent, was astonished and asked humbly:

“But how can you say..., where did you read that?” “I have not read the book,” was the astonishing reply. It turned out that, of the four writers who had gathered to discuss the novel, she was the only one who had read it.

November 21st 2012, near the beginning of the Christmas season, was the date of the publication of the book about the infancy of Jesus, third in the trilogy that Pope Benedict XVI dedicated to Jesus of Nazareth (he also signed them in his own name, Josef Ratzinger).

Let’s look at a review issued in a major daily journal in Spain on the same day of the publication of the book:

Dating the birth of Jesus Christ

Copy of Raphael's The Virgin of the Rose, 
by Manuel Alfonseca Santana

I will not enter here into the nineteenth-century debate on the historical existence of Jesus Christ, for after 1926 historical criticism has unanimously accepted his existence, and the persistence of the idea that Jesus Christ did not exist is solely due to ignorance or anti-Christian bigotry.

In the previous post we saw that December 25 might actually have been the date of the birth of Christ, if we follow a tradition that dates back to Irenaeus. Traditionally, the main argument against that date was the unlikelihood of the shepherds being in the fields in winter, watching their flocks. However, other studies disagree with this statement.
The chronological system used today internationally is the Christian era. After the collapse and disintegration of the Western Roman Empire, the Roman era, which counted the years from the founding of Rome, remained in use for about two hundred years, but in the sixth century, the Scythian theologian Dionysius Exiguus introduced the custom of dating historical events from the birth of Christ. Dionisius calculated that Jesus must have been born around the year 754 AUC (Ab Urbe Condita, since the foundation of the town) and called this year 1 AD (Anno Domini, the year of the Lord). Later dates in the Roman era could easily be translated into the Christian era by subtracting 753 from the corresponding Roman date. As for the years before 754 AUC, in the new era they correspond to negative numbers and can be obtained by subtracting the Roman date from 754 and by adding the abbreviation BC (Before Christ). In this system, there is no year zero.

The celebration of Christmas

Earth lighting in the winter solstice

The time of the winter solstice was the occasion for major celebrations by nearly all ancient peoples. It represents the time when the sun, after losing height for six months, begins again to recover its upward movement. The ancients had always the fear that some year the sun could fail to recover, and would continue down until disappearing forever, a catastrophe for humanity.

In the Roman Empire, the Saturnalia played that role, for Saturn was the god of agriculture and the recovery of the sun was a sine qua non for the success of the next harvest. Also, just by that time the sun entered the sign of Capricorn in the zodiac, which was astrologically linked with the planet Saturn. The festival, which began on December 17, lasted for several days, until the 23rd. During these days, banquets were held, gifts were distributed, and masters served their slaves.

One of the traditional deities of ancient Indo-European peoples, Mitra, had a varied fate, according to the particular people we are talking about. Thus, in Vedic India he was one of the chief gods, along with Varuna and the other asuras, but came to play a secondary role, almost demonic, when in Hindu India prevailed the devas, another group of gods including Siva and Vishnu.
