I don’t know if there is a formal study of the history of numbers and their importance in culture, but if there is there is no doubt that scholars have found that the three most important (and powerful numbers) are one, two and three.
- One for unity.
- Two for duality: (two eyes, two ears, two arms, two legs, etc.)
- Three represents everything else
Religious leaders and some philosophers and scientists like to search for the One. The one god. The one truth. The one unifying theory of whatever.
Naturalists – those who observe nature – have noticed that most things in nature come in twos: two eyes, ears, arms. Two energetic impulses, etc.
Mystics – people who can’t figure out what to make of anything – focus on three – the divinity.
