Pythagoreanism originated in the 6th century BCE, based on the teachings and beliefs held by Pythagoras and his followers, the Pythagoreans, who were considerably influenced by mathematics and they believed that the universe could be understood in terms of whole numbers. This belief stemmed from observations in music, mathematics and astronomy.
Pythagoras believed that all existence could be unified under the golden ratio. This golden ratio can be seen in mathematical formulas, critical thinking, human beauty, harmony, numerology, the arrangement of leaves and branches, and in the DNA of people.
With Pythagoras’s discovery of the golden ratio and its philosophical conception called the Golden mean, the Greeks observed the golden ratio in many parts of the ordered universe both large and small. Philosophically, the Greeks were concerned with a rational explanation of everything and saw the repetition of the golden mean throughout the world and all levels of reality as a step towards this unifying theory. In short, it is the recognition that the same traits appear in entities of many different sizes, from one man to the entire human population.
