Some quick notes on "religion"


You could see religion as a sort of complex system, with myths, moral & symbolic codes, codified worship behaviors (i.e., rituals), and creation-and-destruction narratives. Religions are extremely successful because they give purpose, and meaning to life.    
_________
From the point of view of belief:

Theism, is the belief that some sort of personal God exists and HE is involved with the universe.
Agnosticism: The truth about certain religious claims, is unknowable.
Deism: There is a God but this supreme being does not intervene in human affairs. Deists typically reject supernatural events such as prophecy and miracles.
Monotheism: The belief that there is only one God.
Pantheism: God is the summation of the all universe. God = Nature.
Transtheism: A system of philosophy which is neither theistic, nor atheistic. Paul Tillich writes:
The courage to take meaninglessness into itself presupposes a relation to the ground of being which we have called "absolute faith." It is without a special content, yet it is not without content. The content of absolute faith is the "god above God." Absolute faith and its consequence, the courage that takes the radical doubt, the doubt about God, into itself, transcends the theistic idea of God.
Fideism: It maintains that faith is independent of reason. Tertulian's Credo quia absurdum.

Big Bang (please, watch these videos)



Part 2 here.

What is the age of the universe? The best available measurements as of 2010 suggest that the initial conditions occurred between 13.3 and 13.9 billion years ago.

What caused the BB? Remember: The question doesn't make much sense. It's meaningless. However, it's still logically possible to imagine that the universe is caused.

Cosmogonical myths


Mesopotamian cosmogony:  The basic feature of Mesopotamian cosmology was the firmament, or vault of heaven, that created a dry space above the Earth. The Earth was a disk, and the firmament rested on the Earth around its edge – as was obvious to any Mesopotamian scanning the horizon. Beneath the Earth were the waters of the abyss. The Earth had some thickness as was obvious from digging and from caves. Within the thickness of the Earth-disk was the underworld.

Sumer: Nammu the mother of all. Nammu creates an (heaven) and ki (earth). An, the sky, is a hard metallic shell lies on the earth, ki. The union of an and ki produce Enlil, the god of air, wind, and storm. Enlil lifts an away from ki, filling the space in which humans live. The space is filled with lil (atmosphere). The brighter parts of the lil form the sun, moon, and stars. Enlil also creates all living things. He also invents all the tools used by man and teaches him to use them. But it isn’t Enlil that creates man; it is his son Enki.

Babylon: But there are two kinds of water: fresh, deified in Apsu (male), and salt, deified in Tiamat (female). They call into being a whole genealogy of gods. The new gods were noisy and Apsu complains that he gets no rest either by day or night. This is significant since the gods are still existing in the primordial waters; sun, moon, and earth have not yet been created. This shows that the Babylonians were not aware that day was caused by the sun. They thought of day and night as fundamental and the sun as a mere marker of day. Apsu proposes to kill off the children gods that he and Tiamat have produced. But the gods take measures to prevent this and kill first Apsu and then Tiamat. The latter is accomplished by Marduk who is then the chief god. He splits Tiamat’s body in two ‘like and oyster’.


Ancient Israel: It is referred to as the “Preistly” or “P” account. It is very close to the Babylonian account and was probably learned by the Hebrew priests during Jewish captivity in Mesopotamia. It begins with a formless void of water. Yaweh’s spirit (i.e. breath, like Enlil the air) moves over the waters. He creates night and day; before creating the Sun, just as in the Babylonian myth. He creates the firmament that separates the waters and creates the Earth. He brings forth vegetation first and then produces the Sun, Moon, and stars. After creating all the other living things he makes man and woman and tells them to multiply and dominate the Earth.


Egypt: The Egyptian world view was dominated by the Sun and the Nile. For the Egyptians godhood was flexible. Kings and noblemen could become gods. Even the common people could be immortal. Gods, people, animals, and the natural world were suffused with the same kind of life force. The cosmos emerged from primeval waters, just as in the Mesopotamian myths. It was hollowed out of the abyss, Nun. This was no doubt suggested by the way high ground reappeared, rising from the water as the Nile’s floodtide receded. The primeval waters were held back by an arched living female figure Nut, as shown in figure 3, instead of a metallic firmament; Or in some accounts by a cow or a shell.


Greek: The world began with chaos. Gaia, mother Earth, arose from the chaos. She gives birth Uranos. Uranos is the sky and holds back the chaos. As in the Babylonian myth, there is a revolt among the gods and Zeus becomes the chief god. In the Greek mythology the gods are just humans writ large. They live on Mount Olympus and engage in power struggles and intrigue and sex. As in the Egyptian and Mesopotamian religions, different gods are benefactors and protectors of different cities.

Confucius' Analects (Excerpts)

On Filial Piety

Mang asked what filial piety is. The Master said, "It is being obedient." Soon after, as Fan Chi was driving him, the Master told him "Mang asked me what filial piety is, and I answer him 'being obedient.'" Fan Chi asked, "What exactly did you mean?" The Master replied, "That parents, when alive, should be served according to ritual; that, when dead, they should be buried according to ritual; and that they should be sacrificed to according to ritual." (Note: "ritual" here is "Li" the idea being of developing meaningful practices that can be seen as embodying what is right. For Confucius there must be a blueprint to be followed).  

Ziyou asked what filial piety is. The Master said, "The filial piety of now-a-days means providing nourishment for one's parents. But dogs and horses likewise are able to do something along that line for their own kind. Without reverence, what is there to distinguish the one support given from the other?"

On Goodness

The Master said, "A youth, when at home, should behave well toward his parents, and when abroad, respectfully to his elders. He should be earnest and truthful. He should overflow in love to all, and cultivate the friendship of the good."

The Master said, "With coarse rice to eat, with water to drink, and my bended arm for a pillow, I still have joy in the midst of these things. Riches and honors acquired by unrighteousness are a floating cloud."

Zhong gong asked about perfect virtue. The Master said, "When abroad, behave to everyone as if you were receiving an important guest; treat people as if you were assisting at a great sacrifice; do not do to others as you would not wish done to yourself. Thereby you will let no murmuring rise against in public, and none in private. . . ."

On the Chuang Tzu

The Master said, "Riches and honors are what men desire; but if they cannot be obtained in the proper way, they should be let go. Poverty and meanness are what men dislike; but if they cannot be avoided in the proper way, they should not be avoided. If a gentleman abandons virtue, how can he fulfill the requirements of his title? A gentleman not, even for the space of a single meal, act contrary to virtue. Even in moments of haste, and in times of danger, he clings to virtue."

The Master said, "A gentleman, well studied in literature, and abiding by the rules of ritual, will not go very wrong."

"When gentlemen perform well all their duties to their relations, the people are inspired to virtue. When they remain true to their old friends, the people are preserved from irresponsible behavior."

The Master said, "A gentleman points out the admirable qualities of men and does not point out their bad qualities. A petty man does just the opposite."

The Master said, "A gentleman is distressed by his lack of ability, but he is not distressed by men not knowing him."

The Master said, "What the gentleman demands is something of himself. What the petty man demands is something of others."

A gentleman does not wear a deep purple or a puce color, nor in his at-home clothes does he wear red. In warm weather, he wears a single-layered garment, either of coarse or fine texture, but when going out he wears it over another garment. He wears lambskin with a garment of black, fawn with white, and fox with yellow. His fur dressing gown should be long, but with the right sleeve short. His night clothes must be half again as long as his body. When staying at home, he wears thick furs of the fox or the badger. So long as he is not in mourning, he wears all the trimmings of his girdle. . . . He does not wear lamb's fur or a black cap when making a visit of condolence. And on the first day of the month he must put on his court robes and present himself at court.

On Ritual and Music

The Master said, "If a man lacks the human virtues, what has he to do with ritual? If a man lacks the human virtues, what has he to do with music?"

The Master said, "Respectfulness, without the rules of ritual becomes laborious bustle; carefulness, without the rules, becomes timidity; boldness becomes insubordination; straightforwardness becomes rudeness.

The Master said, "It is by the Odes that a man's mind is aroused, by the rules of ritual that his character is established, and by music that he is perfected [finished]. . . ."

Education is, of course, important to Confucius, as one needs to learn the traditions and profit from the wisdom of the past. Government can then be carried on by "moral force," as opposed to requiring military or legal force. As to religion, Confucius does not challenge it, but he doesn't put his hope in it either. His stress is always on living well, which means living properly, here and now and by our own actions.

Which is more important for an orderly state: food, weapons, or a government that one can trust.

On Education

The Master said, "Anyone learning without thought is lost; anyone thinking but not learning is in peril."

The Master said, "Yu, shall I teach you what knowledge is? When you know a thing, to realize that you know it; and when you do not know a thing, to allow that you do not know it: this is knowledge." The Master said, [I have been] "a transmitter and not a maker, believing in and loving the ancients. . ."

When the Master went to Wei, Ran Yu acted as driver of his carriage. The Master observed, "How numerous the people are!" Ran Yu asked, "When they are more numerous, what more shall be done for them ?" "Enrich them," was the reply. "And when they have been enriched, what more shall be done?" The Master said, "Instruct them."

On Government

The Master said, "To rule a country of a thousand chariots requires reverent attention to business, sincerity, economy in expenditures, and love for men, as well as the employment of the people only in the right seasons."

The Master said, "If the people are governed by laws and punishment is used to maintain order, they will try to avoid the punishment but have no sense of shame. If they are governed by virtue and rules of propriety [ritual] are used to maintain order, they will have a sense of shame and will become good as well."

Ji Kang Zi asked Confucius about government, saying, "What do you say to killing those who are unprincipled [i.e., the immoral] for the good of those who are principled?" Confucius replied, "Sir, in carrying on your government, why should you use killing at all? Let your obvious desires be for what is good, and the people will be good. The relation between superiors and inferiors is like that between the wind and the grass: the grass is bound to bend when the wind blows across it."

Zigong asked about government. The Master said, "The requisites of government are that there be sufficient food, sufficient military equipment, and the confidence of the people in their ruler." Zigong said, "If one had to dispense with one of those three, which should be given up first?" "The military equipment, " said the Master. Zigong again asked, "If on had to dispense with one of the two remaining, which should be given up?" The Master answered, "Give up the food. From of old, death has always been the lot of men; but if the people have no faith in their rulers, they cannot stand."

On Religion

Someone asked the meaning of the great sacrifice. The Master said, "I do not know. Anyone who knew its meaning would find it as easy to govern the kingdom as to look on this," and he pointed to the palm of his hand.

Zilu asked about serving the ghosts of the dead. The Master said, "Until you are able to serve men, how can you serve their ghosts?" When Zilu ventured to ask about death, the answer was: "While you do not know life, how can you [hope to] know about death?"
