A Human Arc is a fundamental representation of perceptions and perspectives as they emerge, exist and evolve across the boundary between your inner and outer worlds. Human Arcs are a way of making sense of the nature of fundamental perceptual flows across the boundary between what is happening inside you and outside you.
The function of the Arcs Space is not to absolutely define your perceptions and perspectives. They are intended to guide you as you engage with what is emerging, existing and evolving for you.
You may often find yourself identifying different perceptions and perspectives in different situations, so just play around with the Arcs Space to make more sense of what is happening inside and what is happening outside.
