Facing Death Alone with no Hope of Rescue

"The Gulf Stream" by Winslow Homer

"Animals learn death first at the moment of death;...man approaches death with the knowledge it is closer every hour, and this creates a feeling of uncertainty over his life, even for him who forgets in the business of life that annihilation is awaiting him.
It is for this reason chiefly that we have philosophy and religion."

Arthur Schopenhauer
The World as Will and Idea
