The hypnotic symmetry in abstractions
Abstract reasoning ignores details, generalizes and simplifies. It exalts principles whilst discarding facts. Ideas are beliefs rather than truths. Ideologies are a matter of conviction and actuality is not their primary concern.
It is in the nature of abstract reasoning to hyperbolize selected principles and to invent tendencies. Exaggeration creates a contrast that facilities comparison, discrimination and reasoning. Contrasting in turn extinguishes nuances, and decolours the picture. It produces cerebral symmetries of logic that are captivating for their simplicity. Especially mesmerizing is the simplest bipolar symmetry perhaps due to its extreme perspicuity as well as to the bilateral symmetry of human body and brain.
Reflection symmetry is logic’s favourite. It is like magical mirror to the mind. Mirror-images of reason are simplified mental projections. Simplicity makes them popular and convincing. Symmetry makes them beautiful. The bipolar logic asks whilst it gives. It questions and offers answers simultaneously. As far as thinking is associated with emotion the logical symmetries are conductive to bipolar disorder. 
As symmetric images attract the eyes so the bipolar categories hypnotize the mind. The self-reflecting mind misinterprets its own monologue as knowledge. It retorts readily at any given time. When reflected long enough even the simplest idea can fill up the entire mental realm. Contrasting ideas is the easiest work to do. It is a type of active mental recovery that never ends. Abstractions are obsessive for their effortless yet unstoppable self-reproduction.
The reflection-symmetric logical structures mesmerize us. We cannot avert our minds from them. But their beauty exists only in perception therefore abstract reasoning is self-entranced. Abstract thoughts estrange the mind from the senses. Ideas are manifestations of mind’s egotism and alienation. Bipolar logic seems to suit the bi-hemispheric brain. It makes thinking self-sufficient and arrogant. Logical reasoning is mental power or debility at the same time depending on the context.
The two-valued system is a type of good-bad logical symmetry that is typical of the morals and abstract doctrines. The holy-unholy partition emphasised by the Abrahamic religions can be traced in apparently unrelated fields of thought. Religious morals have crept in the seemingly atheistic sciences. These include even the cerebral mathematics with its abstract negative integers.
The bipolar mode of saints and sinners, orthodox and infidels needlessly and dangerously polarizes attitudes. It underlies, for instance, the class division in historical materialism. In Freudian psychology it occurs as the everlasting antagonism between the heroic Superego and the destructive sex-drive. In contemporary physics it is found in the bipolarity of all fundamental forces. The holy-unholy division drew the Iron Curtain and sustained the Cold War. Even in modern liberal democracies the godly-ungodly categorization is found to form a constant opposition between left and right-wing politics. The antagonism between liberals and conservators in parliamentary systems may be compared to a permanent Soft Cold War within the democratic societies. It stands to reason that the bipolarity is rather a projection of the human mind than a vital property of the volumetric nature.
What abstract doctrines have in common is a simplified picture of polarized reality. The aptitude of logic to universalize invented the energy quanta. Its liking for simple symmetry charged the elementary particles with opposing electric charges, and later with many other bizarre bipolar properties. Abstract mathematics allowed existence of pure energy and its conversion in matter. The mathematical symmetry applied to corollaries of relativity theoretically allowed the existence of antimatter. Physicists are not bothered by the fact that the oversimplification has lead to extreme intricacy as long as the postulated bipolar simplicity is theoretically preserved. They prefer to think that convolutedness is an attribute of nature not a flaw in the bipolar logic on which their theory is based.
Abstract reasoning selectively ignores facts and regards nature by the piece. The antagonism that it arrives at is artificial and biased. The brain-generated opposition originally served to easier discrimination but if taken literally it falsifies reality. Beyond some point of abstraction the abstract reasoning becomes irrational. Not only that: it becomes arrogant and aggressive.
The least the opposing poles are concerned about is objectivity. Defending their positions is what mainly consumes them. Like electric charges both believers and politicians are preoccupied with distinguishing one from the other and spare little recourses for constructive actions. Sadly, the same applies to scientists.
