Intellectual fluidity is the unencumbered expression of the mind. It moves free from left to right, front to back and every degree in between. It is an extraordinary attribute that can be cultivated by being remarkable at two skills: knowing and un-knowing.
The skill of knowing is obvious. The skill of un-knowing is not. To learn how to un-know is to be liberated from the attachment to knowing. Once you understand that solving problems comes from dealing with untamed realities, then you are free to harmonize improvisations in your mind.
This is the greatest mental showcase. To solve, we must escape the empty acknowledgement of knowing. Be present in the moment and solve with fluidity.
