The Circle and The Square
Both are geometrical shapes that most human beings are well acquainted with. One has 4 joints, the other, none. And that's where the crux of this mini-essay lies.
Could it be said that a square, having 4 well-defined joints, well represents the idea of limitations and boundaries? Since the perimeter is so clearly portrayed. By being more relative, perhaps the square symbolizes the relationship the RATIONAL mind enjoys with physical REALITY. The rational mind accepts limits, and considers boundaries and definitions within ALL it's calculations. For example, the irrational mind might consider the possibility of flight. But the rational mind negates that possibility, considering gravity's presence as well as human physical attributes, which makes natural flight impossible in the physical reality.
But what of the circle? In direct opposite, the circle could represent the irrational mind's relationship with the imaginary reality. Bearing no joints whatsoever suggests the presence of no boundaries, and yet, it opens up the discussion that boundaries might be there as well. This balance in consideration suggests another point, but one that will not be presented in this work. However, focusing rather on the lack of boundaries or LIMITS, the irrational mind, in tandem with irreality (imaginary world), may present to us a whole new list of possibilities.
Of course, such a line of thought can only be considered to be true IF the rational and the irrational are firstly considered as completely opposites.
But then again, it's just a thought.
