The Tree Of Possibilities

Author Bernard Werber (the inspiration for this Encyclopaedia) posited the following theory: if we could see the future, would we not actively build towards a better future? Imagine a tree soaring high into the sky, stretching countless branches in all directions. The many branches of the tree branch off into smaller branches, which branch into even more smaller branches. At the end of each branch, there hangs a leaf. This tree is not a normal tree; it is a Tree of Possibilities that represents the flow of time from the beginning of the universe to the distant future. Each split in a branch represents the creation of two different futures due to a choice or a change, while a leaf represents the final future created from the cumulative effects of these changes. Thus, the Tree of Possibilities is the ultimate crystal ball showing all the pasts that could have been and all the futures that can happen.

Of course the Tree of Possibilities is a fictional model created in our imaginations. But what if we could actually make this tree? First, we would create an organisation of the greatest scientists, mathematicians, sociologists, psychologists, historians, philosophers, science fiction writers etcetera that represent the many fields of knowledge. These people are gathered in a location far from the reaches of governments and the media, where they can discuss without any interference. These specialists will debate over all sorts of topics, amalgamating their knowledge and intuition to generate a tree diagram as mentioned above. This is a diagram free from ethics, morals, laws, optimism, pessimism and individualism – the ultimate objective view of all possible futures that humanity and the Earth may face. The experts may agree with each other at times and disagree at times. There is ample possibility that their postulations are wrong. But none of these matter. The important point is not that the Tree is “accurate” or not, but that it is an extensive scenario database of all the paths humanity can walk on towards the future.

The Tree of Possibilities will have various conjectures such as: What if nuclear war broke out? What if artificial intelligence is perfected? What if chimpanzees reach the intelligence levels of human beings? What if we build cities on the Moon? However, the future is altered much more easily that you would think. Thus, there will also be branches representing much more trivial and ordinary (even bizarre) postulations as well: What if smoking is banned? What if the average age women gave birth is older? What if rhinoceroses were domesticated pets? What if pianos do not exist?

On analysing these numerous postulations, a branch bearing the leaf with the ideal future will be found. Ergo, we can choose to follow a path of least resistance, where all the choices we make will ultimately lead to that ideal future. Essentially, the Tree of Possibilities is a tool that is used to predict the future. However, it is not “fortune telling” as it is based on logic rather than magic and divinity to see into the future. The future the Tree tells is not a set “destiny”, but rather one “possibility”. Thus, instead of fearing the future like we do with fortunes, we would instead feel excitement over the potential of finding the ideal future. If the path we are currently on is fated to an unhappy ending, then we can simply jump onto a different path with the guidance of the Tree. Unlike fortune telling, which destroys all uncertainty and any other possibilities in the future, the Tree of Possibilities provides humanity with the greatest gift: dreams of a better future.

As you could imagine, the possibilities of the future are infinite so a drawn-out diagram of the Tree of Possibilities would take up extensive amounts of space. Ergo, the ideal form of the Tree of Possibilities would be a computer program. As computer programs only need sufficient storage space, it provides a perfect environment in which the Tree may grow. The program would generate a Tree based on the information provided by the scholars, drawing out each branch and leaf, while also calculating the effects of any action on each of the possible futures. If we further applied the engine used in chess programs to predict the next few moves, then we may be able to create a program that can calculate the ideal future and the path of least resistance for humanity.

My ideal future is this. There is an isolated island, far from any interference, with a large building. At the centre of this building, there lies a supercomputer running The Tree of Possibilities. The computer is surrounded by lecture theatres, conference rooms and residential areas. Thus, specialists of each field may come to stay and use their knowledge to water the Tree and foster it. This island will provide humanity with hopes and dreams, leading them towards the best possible future based on logic and imagination.

The Tree of Possibilities will radically change our day-to-day lives. One of the greatest weaknesses of human beings is the inability to see the long-term happiness and sacrificing it for short-term gain. However, if we were able to see precisely how our actions will affect the future, then would we not act differently? Armed with insight and foresight, people will understand what is best for the future, and instead of the current near-sighted attitude of only seeing the gain right before our eyes, they will act in the best interests of their children and grandchildren. Politicians will see how useless bickering over trifling issues is and instead focus on policies that take a while to show the effects (yet nonetheless important), such as environmental conservation. The Tree of Possibilities will help us make rational decisions to create a world that the future generation will be happy living in, without being swayed by emotions and selfish greed. And so, we will build towards a utopia.

The greatest weapon a person has is imagination that can build the future.

In the children’s story Goldilocks and the Three Bears, the protagonist is found trying out various porridges, chairs and beds until she finds the one that is just right for her. Because of this, the name “Goldilocks” has become a symbol for something that is “just right”. A Goldilocks economy is one where there is high growth but no inflation; a Goldilocks planet is one which is not too hot or too cold, making it an ideal planet for life; the Goldilocks effect is when success is achieved because something was not too great or too little.

The Goldilocks effect is a law of nature that is far more important than you would think. Nature always seeks consistency, as shown in the human body. For something as complex as life to exist, a cell must maintain its internal environment in a perfect, ideal state. French physiologist Claude Bernard observed that a cell’s internal environment does not change even with changes in the external environment, and commented that “The stability of the internal environment is the condition for the free and independent life”. This is the basis for homeostasis. Without homeostasis, life cannot exist and all living things put in all their effort in keeping homeostasis. Our body constantly strives to keep various factors such as pulse, blood pressure, oxygen saturation, temperature, blood glucose, electrolytes and numerous hormones etcetera in a stable range. One could possibly argue that the meaning of life is “to maintain homeostasis” – a rather cyclical argument.

To understand the importance of homeostasis, let us look at how changes in the external environment affect us. Our core temperature is maintained in a tight range around 36.5 degrees. If it is altered even a couple of degrees, we exhibit symptoms of hypothermia or hyperthermia. If the weather is too hot, we sweat to cool ourselves; if the weather is too cold, we shiver to raise our temperature. After a meal, we secrete insulin to lower our blood glucose, while we secrete glucagon when starving to raise our blood glucose. Failure of either system leads to either diabetes or hypoglycaemic shock respectively. Homeostasis is an extremely complicated and intricate self-repair system that cannot be imitated.

The Goldilocks effect can be applied beyond physiology to our lives. Everything in moderation; to go beyond is as wrong as to fall short. If we have too little money, it is a problem. If we have too much money, it causes other problems. Whether we work or play, doing too much or too little of either can be bad for us. Medicines become poison in excess and even love in excess becomes obsession. In the marathon that is life, if you run too fast you end up collapsing from exhaustion, while running too slow will mean you never get anywhere.

The secret to happiness lies in understanding what is “just right”.
