Philosophy of the Mind, The Kantian Perspective and Brain Hemispherical Differences

Sensory Perception and its Integration by the Right Mind 


Sight

*Sunlight falling on an object is reflected from its surface in a way that maps the surface features (color, texture, etc.). 

*Light is reflected off of an external Object.

*The Eye receives the image as the reflected light enters through the cornea, and is focused by the lens onto the retina.

*Specialized retinal Light sensitive receptors transmit an impulse through the optic nerve(s) where they form a mapping in the brain, of the visual features of the object.

*Our belief that there is a meaningful relationship between the object and the mapping in the brain depends on a chain of reasoning that is not fully grounded. 

*But the uncertainty aroused by these considerations, by optical illusions, misperceptions, delusions, etc., are not the end of the problems.

The Mind

*Kant saw that the mind could not function as an empty container that simply receives data from outside. 

*Something must be giving order to the incoming data. 

*Images of external objects must be kept in the same sequence in which they were received. *This ordering occurs through the mind’s intuition of time. (Left Mind, the Right Mind does not conceive of time)                            

*The same considerations apply to the mind’s function of constituting space for ordering mappings of visual and tactile signals arriving via the already described chains of physical causation. (The Left Mind determines the boundaries of Space and defines its’ physical self and   separateness)

Synthesis

Concepts, or “categories of human understanding”, are contingent upon Space and Time for the limits of our human senses, to process experience.  

The Left Mind perceives the details and analyzes individual parts, and the Right Mind Synthesizes the parts into the whole.

Space and Time are not concepts themselves, but constructs necessary for our sensual limitations, in this Space-Time dimension, to comprehend experience. 

Space and Time are a priori (they exist as a necessary condition for our perceptions and experiences themselves to occur).

“Thus the objective order of nature and the causal necessity that operates within it depend on the mind’s processes, the product of the rule-based activity.”

-Immanuel Kant (1755)

Unique Right (Parallel Processing) and Left Hemispherical (Serial Processing) 

Wiring Architecture 

Our Right Mind is wired as a Parallel Processor, and able to synthesize multiple streams of data, while our Left Mind is wired as a Serial Processor and focuses on single particular data stream.  

This contrast in fundamental neural architecture, is determinatve of the two minds’ antithetical functions, and thus their disparate expressions and consequent conceived realities.

There is no past or future, only the present moment to the Right Mind.  Therefore it is not subject to the constrictions of the deconstructing limitations of the Left Mind, which is wired as a serial drive.

Our right brain hemisphere functions like a parallel processor. Independent streams of information simultaneously burst into our brain via each of our sensory systems. Moment by moment, our right mind creates a master collage of what this moment in time looks like, sounds like, tastes like, smells like, and feels like. Moments don’t come and go in a rush, but rather are rich with sensations, thoughts, emotions, and often, physiological responses. Information processed in this way allows us to take an immediate inventory about the space around us and our relationship to that space.”

In  contrast, our left hemisphere is completely different in the way it processes information. It takes each of those rich and complex moments created by the right hemisphere and strings them together in timely succession. It then sequentially compares the details making up this moment with the details making up the last moment. By organizing details in a linear and methodical configuration, our left brain manifests the concept of time whereby our moments are divided into the past, present, and future. Within the structure of this predictable temporal cadence, we can appreciate that this must occur before that can happen. I look at my shoes and socks and it is my left hemisphere that comprehends that I must put my socks on before my shoes. It can look at all the details of a puzzle and use the clues of color, shape, and size to recognize patterns for arrangement. It builds an understanding of everything using deductive reasoning such that if A is greater than B, and B is greater than C, then A must be greater than C.”
-Dr. Jill Bolte-Taylor, excerpt “Stroke of Insight”

Only the Right Mind can operationally and functionally Synthesize sensory input into an universal or whole construct, as its parallel drive anatomical architecture must necessarily produce.  

Only its’ apparatus is capable of creating a consistent, cogent, ever-expanding and integrative World View.  

Only those who have achieved access to their right mind and have subsequently aligned with their essential nature, via their Right Minds’ Authentic-Self, can opt to usurp control from the egocentric Left Mind and Actualize as they will to.
