We know the memories about continuity, but the condition where there no continuity is, we don't know

Identity as some images of life, as experience, belief and knowledge, as a striving after becoming something, a will to power, a will to control, master, frame, no matter on what level, is hard to understand and bring up in the light.

We only know continuity, we have no knowledge about non-continuity.

We know the experiences, the memories about the continuity of the events, but the condition where there no continuity is, we don't know.

We call it death, the unknown, the secretiveness etc., and by giving it a name, we hope to be able to maintain it, which again is the desire after continuity, the permanent.
