The Two Greatest Primal Fears.

Eternity denial is much like death denial in the degree of primal fear it creates.
Both are very real, and neither can be avoided, no matter how much religious dogma we create to assist in our denial. Time tells us dogma is finite, even if people take its fraudulent belief systems to the grave. Dogma may change to adapt to new societies, but because the individual is more important than the society, dogma will always die. And death is eternal, though eternity is not death.
