Topic 1: The Truth Surrounding Human Complexity
It is important that we first understand what we do know, before we can begin to understand what we don't know. The pattern of life is consistent and repetitious. Our existence will begin with the mating of two simple specialized cells. They will increase in complexity through growth and differentiation over time(anabolism). Once we reach the height of our metabolic complexity, we begin to slowly catabolize over time. In other words, we become less complex and less energy efficient. During this period of the cycle, new changes, new knowledge, new growth, new proficiencies, new languages, and new habits are very difficult to acquire. This decline in complexity and energy efficiency will eventually lead to the death of the organism. Everything that we observed as being complex, in reality, is based on underlying layers of simplicity. Cells are made up of simple organelles. Organs are made up of simple cells. Systems are made from simple organs. Brick homes(no matter how complex the design), are made from simple bricks. A complex musical score for a symphony, is composed of simple notes. An intellectual symposium is still composed of simple words. Even the most complex math is based on simple addition. It is through these underlying simple building blocks, that we can begin to understand the added complexities inherent in all natural phenomenon. This understanding is vital for our survival. And, the more we can learn, the better our chances for survival will be. Our physical senses follow this same cycle of simplicity, growth, maintenance, and decline.
We all know that what we see is not only inverted(upside down), but is initially colourless. Visual images are created when a small portion of the electromagnetic spectrum(massless photons) stimulates the physical receptors on the retina of the eye. Low level excitation(white light) and high level excitation(colour). Each sensory signal is interpreted by the brain as a tiny visual portion of our objective reality. The more sensory input to the brain, the better the picture the brain can present. Unfortunately, there is not enough signals to give the truest image, so the brain must fill in the blanks. It's best guess, if you will. The level of functionality is determined by our genes. This truth can be easily seen in observing the effects of many visual maladies. This means that what we see is only a composite image, based on information the brain receives from simple specialized cells.
We all know that taste and olfaction(smell) are the result of stimulating specialized receptor cells on the tongue and the roof of the nose. They are both stimulated by only a few molecules on the tongue, or in the air. Of course molecules themselves don't have taste or smell. It is the brain that makes that interpretation. Again the differences in interpretation is also determined by our genes.
We all know that sound is only an audible vibration of pressure wave moving through the air(or another medium). This vibration of air is picked up by our outer, middle and inner ear(cochlea). These pressure waves cause different regions of the basilar membrane(thin to thick) to vibrate, and the hair cells(organ of Corti) to send its impulses to the brain. The brain then knows what area of the membrane is vibrating. This information is presented to our consciousness as different sounds and different pitches(music, sound, etc.). Therefore, what we perceive as sound or music, is only the representation of what areas of the basilar membrane is being stimulated. This can easily be duplicated in the lab. Again, our auditory sense is controlled by our genes.
Finally, our sense of touch is the brain's representation of the amount of compression on mechanoreceptors(Merkel's Disk, Pacinian Corpuscle, etc.). Again it is the brain and our language that interprets and represents all the information that it receives from its receptors. Anything that is not detected by these receptors, from a subjective perspective, simply do not exist.
My questions are, are we something greater than the sum of our parts? Or, are we only the outward manifestation of these parts? Are we really so complex, or just a composite of simple systems working together to survive? As we age, do our senses age with us? If so, can we still trust our brain's representation of our senses? How do you think our reality may be altered if our senses misfire? Do you think that Belief can have any effect on how the brain interprets sensory input? Are we all simply trapped in our own subjective perspective? Don
