Are you imagining your fears?

Human beings feel very vulnerable. Totally at the mercy of destiny, and forever battling circumstances, waging a war against financial, emotional and social insecurity. We are perennially choosing from a myriad options and we keep hoping we’ve made the right choice. The fear of the unknown tends to loom large and we spend most of our present worrying about the future. This despondency drives many to soothsayers, clairvoyants, astrologers and palm readers and futurologists. If we look around and take a few cues from nature, it seems animals and birds live life with scarce planning, manipulation or worrying about tomorrow. And they manage all right, too. Humans are unique in that they are bestowed with frontal lobes, those extensions of the brain that insinuate between the eyebrows and the hairline, which also cleave us from our immediate ancestors, the apes. Frontal lobes are the seat of abstraction, intellect, and empower us with qualities like imagination, and conceptual thought. Our primitive nervous system was designed to enable us to perceive and interact with the environment. Successive evolutionary improvements in the nervous system served to increase the speed and complexity of the response, albeit only as a reaction to the environment. But with the frontal lobes appearing in us humans, we could engage in abstraction. Philosophy, poetry and culture are some intangibles that the human brain could delve into. But then came the catch. This added faculty - the power to use creative imagination - also became a tool to conjure abstract fears. The fear of the unknown, the concept of destiny, suspicion, anxiety and the entire spectrum of "imaginary" fears and angst. But then was that the objective of this latest edition of the brain? To believe that this device was designed only to make life more comfortable is a bit far-fetched. We can take the credit for advancing technology, making inventions, and generally utilising the tool effectively. But we still have to realise that we just utilised the tool. We are not the creator of this tool. So what is the objective of this very versatile complex nervous tissue that has helped man transform the external world? Was it to distort and manipulate the external world? Couldn’t the creator have done so himself? Abstraction was given as a boon to us to comprehend the 'inner' world. It is unlikely that other species would query "Who am I?", or "Why has this creation been made?" These are doubts that can arise only as an extrapolation of the thought process beyond the travails of daily mundane living. So this heightened ability of imagination and comprehension was made available for the human mind to fathom itself. An ability no other animal possesses. Needless to say almost all fears arising in the mind are a side-effect of this enhanced cognitive ability. Nothing more than that. The knife with a sharp cutting edge is a very versatile instrument if it is used appropriately. We as proud owners of this add-on gadget need to realise that this tool has to be utilised for the appropriate objective of self-knowledge. To understand the self. To look within and not misuse it to end up as hypertensive and diabetics, disorders very human- specific stemming from gross misuse of this magnificent evolutionary upgrade.
