Open-ended development. This spiral development depicts phases in open-ended development and terms typically associated with different development phases. The inner rotation can be described as learning to master the body, the second rotation as making the mind a reliable tool and the third learning to effectively co-create an optimal living environment. We propose that this corresponds to a progression from right to left to right hemispheric dominance and associated strategies. [Inspired by the depiction in Arnold, (1910), p. 23].
