I agree with Nick’s “Moby-Dick has an underlying, irrational and transcendental structure. The circle” However I come from the perspective of the human psyche and the symbolism that our minds create cross culturally that appear to have a universal base. The significance of circles and squares as having "transcendental structure" underlying their practical usage can be understood as the metaphysics of geometry.
Symbolically circles in the West and East represents the notions of wholeness, perfection, spiritual oneness, and eternity. The square is associated with mankind’s creations that can be measured with straight lines, laws, and intellectual structures.
Just as the ancient astrologers projected their beliefs upon the sky, the alchemists imposed their beliefs upon the elements. “Squaring the circle” was their way of describing their efforts in geometric terms for the process of discovery of the lapis philosophorum.
We know Melville knew how geometry can describe physical laws as well as human understanding of oneself..
In the Try-Works “It is a place
also for profound mathematical meditation. It was in the left hand
try-pot of the Pequod, with the soapstone diligently circling round
me, that I was first indirectly struck by the remarkable fact, that in
geometry all bodies gliding along the cycloid, my soapstone for
example, will descend from any point in precisely the same time.”
Therefore squaring Melville’s circle with the accepted intellectual structure I use, the irrational Pip is the Pi that relates “the circumference to its centre.” From my perspective of the human psyche the irrational that links the square of Ahab’s weltanschauung with his experience of the circle of his feeling is Pip. Pip is the the irrational experience of Ahab’s emotions that he is running from. The positive emotions he sees in Pip make his circle a whole and holy. The negative emotions he sees in Moby Dick he refuses to accept responsibility for and therefore chooses to die believing in his square view of the source of his suffering
. The key Ahab cannot integrate is "I look, you look, he looks; we look, ye look, they look." For we all look and what we believe in response to what we see determines our emotions that govern our actions. That is how this reader squares the Melville Circle.

his brain seems that geometrical circle which it is impossible to
square." The Nut
