( Puzzles Our Will )
On why we, human beings, and most likely the only sentient beings, fear death, I posit the following:
We do not know how to sit with our selves and do nothing, for from the point of coming into this human world, we are socialized, nurtured, and then expected to be doing, over-doing, and out-doing each other.
So, when the possibility of death enters in life, or when we begin to understand that all living things must die, not as some distant future happening, but every nanosecond of life, we are dying and living simultaneous at the cellular level, we start to form our unhealthy disassociation from our very natural, innate nature of human life, in a vain attempt to minimize our cosmic fear of death.
A Sysiphean journey it proves to be for us to minimize our fear of death, for the only viable possibility is to accept it, thus learn to die, all along the journey of living, gracefully before the final curtain, much like an actress learns to accept, embrace her character's every facets of being, in order to deliver a true, three-dimensional portrayal.
Another psychological wall we hide behind is what Shakespeare refers to as, "The undiscovered country from whose bourn//No traveler returns... ;" the fact we have been bamboozled, hoodwinked into rejecting cosmic randomness and mystery in general, we form as a result an adverse relationship to anything we cannot manipulate into submitting to our perverse linear order of doing and thinking.
We don't know what happens really after death, although some well-meaning religions have given us some comforting possibilities; nevertheless, the fear and denial of death itself has persisted, and has sent us to seek refuge in the dark corners of legacy, which then manifests itself as an insidious Cesar's complex, in which we want to live beyond our own death through our earthly accomplishments, regardless of how many we have to trample on in our emperor-like or god-incarnate, but more like Hades incarnate, pursuit of those accomplishments.
