Someone told me the secret of dominant Ne yesterday. It was funny, because afterwards, I understood why I could never put words to it.
Think of reality as a waveform. You have crests and you have troughs. Where it crests, you have matter and material things. Where it troughs, you have emptiness. In both the crests and the troughs you have existence, for the emptiness is defined by a lack of matter, but the matter only has meaning in that it is not empty.
Sensing focuses its perception on matter and energy. It orients toward the crests of existence.
Intuition focuses its perception on emptiness and space. It orients toward the troughs of existence.
Extraverted intuition particularly focuses on the near-limitless emptiness throughout our external world. As a dominant function, it embraces this emptiness as the source of pure potential. Imagination and abstraction provide means of filling the emptiness and harnessing the power of creation. The drive is to take what is on the crests and fill the troughs with enough so that there is balance and harmony in the universe.
That's the secret he told me. Se focuses on what's there. Ne focuses on what's not there.
