Why does the brute flee, trembling, and seek to conceal itself? Because it is simply the will to live, but, as such, is forfeited to death, and wishes to gain time. Such also, by nature, is man.

Context

“Thus it is the fear of death, and not the mere avoidance of pain, which shows itself in the anxious carefulness with which the brute seeks to protect itself, and still more its brood, from everything that might become dangerous. Why does the brute flee, trembling, and seek to conceal itself? Because it is simply the will to live, but, as such, is forfeited to death, and wishes to gain time. Such also, by nature, is man. [pg 252] The greatest evil, the worst that can anywhere threaten, is death; the greatest fear is the fear of death. Nothing excites us so irresistibly to the most lively interest as danger to the life of others; nothing is so shocking as an execution.” source
