What is Duality… Really?
According to Websters, duality is defined as:
the quality or state of having two different or opposite parts or elements : dualism.
Historically and traditionally these two different parts are often viewed as Heaven/Earth, God/Human, Spirit/Matter, Self/Other, Light/Dark, Good/Evil (a.k.a. old dualities) and so forth.
In terms of quantum physics a fundamental duality of two parts is believed to exist as Wave/Particle and/or Vibration/Matter.
These historical fundamental dualities existed long before we were scientifically advanced enough to identify atoms and their related sub-atomic realities such as the Wave/Particle duality. This is, however, quite a key point to contemplate more deeply!
Why? Because it’s easy to see that we were steeped in deeply rooted and often superstitious notions of duality long before we began trying to make sense out of, and interpret our observations of, the quantum world. It’s therefore fairly easy to understand that we’ve been observing and interpreting the quantum world through a rather thick lens of duality from the very beginning.
Given we have measured and observed both wave and matter properties associated with quantum ‘particles,’ it would also be quite natural to interpret quantum particles as having a dualistic Wave/Particle nature. This concept would quite effortlessly emerge out of our age-old dualistic patterns of perception and thinking.
