Virgin Birth

Although the concept of virgin birth (i.e. conception without intercourse) is common in many religions, there is no conclusive evidence of actual human virgin birth in recorded history. Except in one medical article written in 1874 by a Dr Capers.

In this article, Dr Capers describes a case study of a miraculous conception during the Battle of Raymond during the US Civil War. A soldier was shot in the testicles and the musket ball carried the non-musket ball (read: testicle) into the uterus of a girl working in a nearby field. The doctor attended to the girl who was shot and treated the wound in her abdomen. The bullet was not found.

Over the following nine months, the doctor realised the girl was pregnant, although she claimed to be a virgin. After nine months, a healthy boy was born. Stranger yet, the doctor realised the boy’s scrotum was unusually swollen and upon examination, found that he was carrying the musket ball that impregnated the girl in the first place. He thus concluded that the testicle that was carried by the musket ball was lodged inside her uterus and sperm leaked out. The soldier was eventually found and was told about this bizarre story and the two were married.

This case study has become a famous story told by doctors around the world. Unfortunately, it is completely false and the doctor who wrote the article admitted to faking it to amuse himself. Ergo, there are still no recorded cases of a virgin birth in humans.

The closest to a virgin birth that was recorded is a case study of a young woman who was performing oral sex on a man. She was found by her boyfriend during the act and the boyfriend stabbed her and her lover with a knife. The knife injured her oesophagus, causing the sperm in it to track down the abdomen and down to her reproductive organs. By a stroke of luck, an egg was misplaced during ovulation, causing it to drift into the abdomen instead of the fallopian tube (ectopic pregnancy), and met with the sperm. The egg was then fertilised and the girl presented to the hospital three months later with excruciating abdominal pain. The ectopic fetus was removed.

Spelling Alphabet

One weakness with the English alphabet is that when they are spelt out aloud, some letters are too similar and end up being confused. For example, B sounds like D and M sounds like N. Although this is not too major an issue in normal life, it becomes very problematic when giving important information over the phone, such as an identification number. The same problem applies in the military where precise orders are required. To overcome the issue of similar-sounding letters, many systems have been developed to replace the letters with words when spelling words aloud over the phone or radio. For example, if the ID number EFS9201 has to be told to the other person, it can be read as “echo-foxtrot-sierra-nine-two-zero-one”. It is also used in the military to say abbreviations, such as “oscar mike” for “on the move”. As the spelling alphabet system is designed so that no two words sound similar, it is a very effective way of accurately transmitting information over the phone.

The spelling alphabet (NATO phonetic alphabet) is as follows:

Noblesse Oblige

Noblesse oblige is a French term that literally translates to “nobility obliges”, stating that those with wealth and power must also take responsibility of the society they lead. Also, it requires the nobles to show a high level of morality, acting out the duties of a citizen. The etymology of this term dates back to the 14th century in the French city of Calais during the Hundred Years’ War.

During the war, the city of Calais was under siege from the English army. They fought valiantly for a year but ultimately surrendered to the English. The English desired to execute every citizen for making them fight for so long, but considering the bad press they instead announced that they would let the citizens live on the condition that six people take responsibility for the battle and are executed for it. The citizens were in agony. Who would sacrifice their life to protect the lives and safety of the other citizens? At that moment, Calais’ wealthiest man, Saint Pierre, volunteered to be sacrificed. Following his brave act, five other bourgeois of Calais, including the rich, noble and lawyers, put up their hands and stated that they would gladly give up their lives for the city. Moved by this sacrificial spirit, the queen of England convinced Edward the Third (then English king) to cancel the execution and have mercy. This story became the foundation of the noblesse oblige spirit of “those who are noble should take responsibility first”.

Although it is a very touching story, it is also an uncommon one. Instead, it is much more common to hear stories of the upper class fleeing the country and protecting their own lives when their country is in peril. A true developed nation should have those who lead a wealthy life work harder for the country than regular citizens. We should not be following the social Darwinistic belief of survival of the fittest, but rather show harmony where the strong help out the weak. In the case of the Roman Empire, nobles believed that what set themselves apart from slaves was not their status, but their ability to carry out social duties, having great pride in practising noblesse oblige.

The most common example of noblesse oblige would be the rich giving money to charity, but there are other duties of a citizen other than paying taxes (a way of redistributing wealth). A citizen must respect and follow the law, vote to practise democracy, pay their taxes, receive education and much more (in some countries, conscription is a duty too).

When the Korean War broke out, the first chairman of the People’s Republic of China, Mao Zedong, sent his first son to participate in the war. After his son was killed in action and many people asked him why he sent his own son to war, he replied: “How could I as a leader ask my people to send away their sons to war when I am not willing to send my own son away?”.

The higher your social status, the more wealth and power you have, you should thoroughly upkeep your duties as a citizen and help out so that everyone can live happily.

(Les Bourgeois de Calais by Auguste Rodin, a sculpture depicting the six nobles of Calais who stepped up to be executed)

The Great Dictator

The following is the final speech given by Charlie Chaplin in the movie The Great Dictator (1940). To this day, it is considered one of the most inspirational speeches in modern history. (NB: video excerpt at the end)

“I’m sorry, but I don’t want to be an emperor. That’s not my business. I don’t want to rule or conquer anyone. I should like to help everyone, if possible, Jew, gentile, black man, white. We all want to help one another. Human beings are like that. We want to live by each other’s happiness – not by each other’s misery. We don’t want to hate and despise one another.

In this world there is room for everyone. And the good earth is rich and can provide for everyone. The way of life can be free and beautiful, but we have lost the way. Greed has poisoned men’s souls, has barricaded the world with hate, has goose-stepped us into misery and bloodshed. We have developed speed, but we have shut ourselves in. Machinery that gives abundance has left us in want. Our knowledge has made us cynical. Our cleverness, hard and unkind. We think too much and feel too little. More than machinery we need humanity. More than cleverness we need kindness and gentleness. Without these qualities, life will be violent and all will be lost.

The aeroplane and the radio have brought us closer together. The very nature of these inventions cries out for the goodness in men, cries out for universal brotherhood, for the unity of us all. Even now my voice is reaching millions throughout the world – millions of despairing men, women and little children – victims of a system that makes men torture and imprison innocent people. To those who can hear me, I say – do not despair. The misery that is now upon us is but the passing of greed – the bitterness of men who fear the way of human progress. The hate of men will pass, and dictators die, and the power they took from the people will return to the people and so long as men die, liberty will never perish.

Soldiers! Don’t give yourselves to brutes – men who despise you – enslave you – who regiment your lives – tell you what to do – what to think or what to feel! Who drill you, diet you, treat you like cattle, use you as cannon fodder. Don’t give yourselves to these unnatural men – machine men with machine minds and machine hearts! You are not machines! You are not cattle! You are men! You have the love of humanity in your hearts. You don’t hate! Only the unloved hate – the unloved and the unnatural!

Soldiers! Don’t fight for slavery! Fight for liberty! In the 17th Chapter of St. Luke it is written: “the Kingdom of God is within man” – not one man nor a group of men, but in all men! In you! You, the people have the power – the power to create machines. The power to create happiness! You, the people, have the power to make this life free and beautiful, to make this life a wonderful adventure.

Then, in the name of democracy, let us use that power! Let us all unite! Let us fight for a new world, a decent world that will give men a chance to work that will give youth the future and old age a security. By the promise of these things, brutes have risen to power, but they lie! They do not fulfil their promise; they never will. Dictators free themselves, but they enslave the people! Now, let us fight to fulfil that promise! Let us fight to free the world, to do away with national barriers, to do away with greed, with hate and intolerance. Let us fight for a world of reason, a world where science and progress will lead to all men’s happiness.

Soldiers! In the name of democracy, let us all unite!“

Phantom Limb Pain

In up to 80% cases of amputations, a strange phenomenon occurs where the amputee reports sensation or even severe pain where the limb has been amputated. It was noticed in field hospitals during wars when a soldier would wake up and ask someone to scratch his leg – which was no longer attached to his body. The sensation can be so powerful that victims actively believe that their phantom limb can interact with real objects. For example, there have been case reports of patients trying to pick up a cup with an amputated arm and becoming frustrated with their inability to.

Phantom limb pain may persist even after the amputee realises the limb is no longer there. The basis for phantom limb pain is a neurological system called the cortical homunculus. The cortical homunculus is a concept that the part of the brain responsible for sensation and movement is mapped out so that each part corresponds to a part of the body (see picture). For example, the top of the primary somatosensory and motor cortices (said parts of the brain) is responsible for foot sensation and movement while the side receives information from and sends signals to the face. It lets the brain construct an image of what the body looks like from sensory information it collates from various body parts. It is suggested that phantom limb pain is caused by a remapping of the cortical homunculus, fooling the brain to think that the limb is there even if it has been physically cut off. This also explains a similar condition called supernumerary phantom limb, where the brain believes there is an extra limb (e.g. a third arm).

As the homunculus concept is a recent idea, treatment options had not advanced much until the late 1990s. In 1998, a neuroscientist called Dr. Vilayanur S. Ramachandran devised a method called the mirror box treatment. He noticed that victims of phantom limb pain (PLP) had paralysis or pain in the limb just before the amputation (such as tightly gripping something before the arm got blown up by a mine), suggesting that PLP may be a form of learned paralysis. This means that the brain believes that the arm is still paralysed and any movement causes an uncomfortable sensation as the brain thinks the limb is contorted into a painful position. To fix this problem, Dr. Ramachandran invented a box with two holes, each going into a separate compartment. One compartment is for the good arm while the other has a mirror positioned on an angle to reflect the other arm (instead of seeing the stub they put in the hole). He would then instruct the patient to perform symmetric movements with both hands while looking at the reflected arm. For example, he would tell the patient to squeeze their “fists” tightly as possible and then let go. Through this procedure, the brain is retrained to let go of the perceived paralysis and pain as it is tricked in to thinking that the arm is healthy again. The mirror box therapy drastically improved the outcome and quality of life of PLP patients through the power of illusions.

Brainwashing

The term brainwashing describes the act of converting a person’s deepest thoughts and ideologies. The term originated from the efforts of the Chinese army to convert US soldiers to communism in the Korean War.

The Chinese first made American prisoners-of-war write essays hailing communism, then gave them some rice, candy or cigarettes as rewards.
The intelligence officers posited that the prisoners would be tormented by the reality of having to act against their ideology (of anti-communism) to receive such petty rewards, and that they would convert their beliefs to escape this. They were right.

A significant number of Americans who were given rewards after writing the essays defected to become communists after the war. This was because they justified their actions, believing that they did not write the essays to get a few candies, but because they truly are communists. Converting them did not require horrific torture or heavy bribery. All the officers needed were some candy, and the powerful psychological phenomenon known as cognitive dissonance to play with a grown man’s mind.

Leon Festinger said: “People are not rational beings, but beings that rationalise themselves”. People easily get caught in the trap of self-justification, and distort reality and even their own memories to accommodate it.
