DANGER
Since conscience emerged in humans, many
hundreds of thousands years ago, the sense of
danger
was an important part of it.
Danger in the environment from wild neighbours
(mammoths, tigers, etc), danger from climatic
convulsions, danger from other humans.
Managing
the ubiquitous danger was a condition for
survival and life propagation. Quite obviously,
humans have been good (too good ?) at managing
danger in their daily life.
