There is a powerful emotion in all creatures and it's called fear. It is a survival instinct and has probably been the single greatest reason any species has been able to survive and reproduce. The urge to reproduce is another powerful drive but I will save that one for a future post. Fear can keep an animal from approaching danger. It can keep that creature on high alert when danger is imminent. It can cause a flight/fight reaction when danger is present, allowing a creature to deal with or escape the danger. It serves a vital purpose in the world and yet we humans attempt to eliminate it from our lives. Is that wise?
We are made miserable by fear. It creates a pervasive dread that hangs over us like a cloud. It can be a suffocating fog that clouds our judgement and paralyzes us into immobility. It can destroy our ability to function effectively in the world. It would seem that eliminating it from our lives would be desirable but what would be the unintended consequences of such an elimination?
Fear is a powerful motivator... perhaps the most powerful. It compels us to act when nothing else will. It drives us (through our desire to escape it) to advance, grow, develop, evolve and improve our surroundings and make our lives better. Losing fear from our psyche will cause all those positive impulses and drives to slow or stop. It will stagnate and eventually reverse our development as a species. We will begin a process of devolution and will fall victim to some predation or, even, die off from apathy or entropy.
Manage fear, certainly. Eliminate it? Never. Not if we wish to survive.
