Embryos think with each stage of their development that they have now reached the only condition that really suits them. This, they say, must certainly be their last, inasmuch as its close will be so great a shock that nothing can survive it. Every change is a shock; every shock is a pro tanto death. What we call death is only a shock great enough to destroy our power to recognize a past and a present as resembling one another.
There are moments of despair that come sometimes, when night sets in and a white fog presses against the windows. Then our house changes its shape, rears up and becomes a place of despair. Then fear and rage run simply--and the thought of Death as a friend. This is the simplest of thoughts, that Death must come when we call, although he is a god.
