哲学家关注死亡是因为死亡是“最本己的、无所关联的、确知的、而作为其本身则是不确定的、超不过的可能性。”死亡,作为事件,从来都是别人的。因为死亡是不能够被经历的,用哈姆莱特的话说就是:“死亡是一个有去无回的旅程”。也就是说,没有哪个旅客能够从死亡的旅程里返回。这也标志着生命的一次性性质,作为一次性的生命,谁都有权利将它(生命)使用得更好更恰当。因此说,建基于思考死亡的生命哲学才可能是最真实的生命哲学。 Philosophers are concerned with death because death is “the most self-contained, unconnected, and indeed known, and as such is uncertain and beyond possibility.” “Death, as an event, has always been other’s. Because death can not be experienced, in the words of Hamlet: ”Death is a journey back and forth ". In other words, no traveler can return from the journey of death. It also marks the one-time nature of life, and as a one-time life, everyone has the right to use it better and more appropriately. Therefore, it is possible that the philosophy of life based on thinking of death can be the most authentic philosophy of life.
