Numerology is so much more than we think. We take numbers for granted and do not think much about their meaning and what each number encompasses. Nevertheless, our world is based on numerology and numbers are all around – in our bodies’ proportions, in plants, in music, in every heartbeat. Basically, we are surrounded by numbers without even being aware of it. Except when we gamble, right? Have you ever thought about the number 2 and its meaning?

Maths or Philosophy

One of our favorite numbers is number 2. It screams duality and balance. Number 2 is all about interaction and equalization. In order to truly understand the nature of numbers, we need to take a short look back at some of the famous philosophers and mathematicians who explored this subject. Yes, philosophers dealt with this subject as well. Apparently, numbers are more than just graphic presentations of value or quantity.

We were taught that numbers are logical constructs. To us, they exist in the abstract world. Therefore, we can easily grasp only their partial concept. If something is doubled, we ascribe the 2 to it. However, the philosopher Kurt Gödel developed the theorem that says that “if numbers exist in the mathematical sense—then that fact can never be proved mathematically”.  This is the theorem that launches the concept of numbers to a mystical field, which is still beyond our full comprehension.

Back to the meaning of our favorite number 2, we should remember that this number has been explored and thought through many times in the past. Although we know so much about it nowadays, there are still aspects to discover in the future.

Number 2 in Ancient Greece

Number 2 is the only even prime number. It is also the smallest and first prime number, since every other even number can be divided by two.

We learnt about Pythagoras’ Theorem, but not too many of us heard about Pythagoras’ Constant. This is the first irrational number that has ever been discovered. It amounts to app. 1.41 and represents the square root of 2. The calculus itself dates back to Babylon times, believe it or not. Moreover, for the Pythagorians, this discovery of the irrational number at the basis of number 2 came as a big surprise and disbelief. Namely, it shook their understanding of the universe derived around whole numbers. Therefore, in ancient Greece number 2 was the unlucky number, according to the Pythagorians. Additionally, they even dedicated the second day of the month to Hades, the god of the Underworld.

On the other hand, Sparta, also in ancient Greece, had a belief of its own. This belief did not relate to the negative aspect of number 2. Contrary, Sparta had two kings on its throne, the Agiad and the Europontids. Spartans held them to be descendants of Heracles. Hence, they ruled with the same authority.

Number 2 in Ancient China

In ancient China the Daoists placed the foundation to one of the most widely accepted beliefs to this day. Namely, they claimed that the world is based on duality: the yin and yang principle. These two principles keep the world in balance.  The number 2 is usually related to the Yin. Yin is the female principle and symbolizes the earth, the cold, the dark and the soft.

The Chinese went even further and developed the legend of the Earth God, Tu Di Gong and the keepers of his temple, Men Shen. The keepers come in pair and represent two door gods which are differently represented. One is white, the other is either red or black. Either way, their representation is quite strong. They look very strict and they prevent the entrance and the evil demons from entering our world.

If we take a look at number two from the more mathematical point of view, it is the number of division. It separates the whole in half. From metaphysical or “mystical” point of view, two is the number which reflects relations, be it rivalry or companionship. It forces us to rethink our decisions and to unite. Two teaches us that there is no me without you.
