The Optical Illusion of Common Sense

Common sense sounds like a sensibility that is common to a species such as human beings. An outlook that arises out of common sense is very often supported by specious arguments. This appears to be a contradiction; or does it? It would not be a contradiction if the outlook is based on certain principles, perceptions and biological mechanisms that can turn out to be limitations. Physics is instrumental in revealing the optical illusion of what we consider to be common sense. It is made to look like a misnomer. The Greek philosopher Plato is noted for his allegory of the cave. By way of the allegory, he shows how people get deceived by what they see. They mistake appearance for reality without knowing, poor chums, the sweet and bitter deceptions that ensue once the curtains subside. When they see what happens behind the curtains, they are in for a treat. Some become disillusioned with their senses and wish to pursue physics and even philosophy. 

The converse is also true. If you come to study sensory inputs threadbare and you start doubting the reality of what you see, you are sometimes scared that you may be mistaking a snake for a rope, when what you are seeing is nothing but a harmless rope.  You do not trust your senses at all to a point where it is dangerous. It is also true that a perspective that takes years to prove can be realized very easily, by common sense. Is common sense a particular faculty in our brain or is it just a simple way of thinking which we overlook? 

Some prefer the simple to the far-fetched. Supposing in a restaurant, there are many novel types of soups in the menu. Your friend tells you that he is going to opt for tomato soup. You remark, “What...despite so many options!” He responds, “I prefer the simple to the far-fetched”. This applies not only to choices and preferences but also to thought and intuitions. Sometimes there is truth in what meets the eye. It is not the figment of our imagination but that of skepticism that keeps us from making progress in all our endeavors.  Common sense is a shared way of perceiving the world and understanding the sensory inputs that we receive. It eludes us because of what we have learnt and the subjective reasoning that we have grown accustomed to practicing as a matter of habit. 

The world exists outside the clinic! The universe cannot be captured by a microscopic outlook.

  1. Very well put... The trick is to simplify things as much as possible... Sometimes trying to find some underlying phenomena that might not be there is perhaps what happens with too much skepticsm...

  2. The will to doubt is not the same as the will to find out. The former is utter skepticism while the latter is curiosity. Curiosity brings the cat to life. Doubts are natural responses to claims that do not seem to be understandable. They may not be convincing as well, which is why the individual doubts them as a natural response. One cannot make a profession out of it. Skepticism is not a stand.
    When you wish to find out, there is wonder and marvel to follow. There are approaches other than the ones accepted by scientists which give us more insight about natural phenomena. They deserve attention and the scientific community do not have a monopoly over truth and human understanding. Sometimes all one needs is a bit of common sense.

  3. Very accurate. The will to find out is what brings answers. Merely questioning things without any intention of getting answers is just hiding behind skepticism. Some say "I will not believe it unless you show me proof." Well too bad. My belief does not depend on someone else's approval. Experience is what provides the proof. Very often experiences cannot be put in any language known to man, but to the one to whom this experience happens, it is very real.
