Abstract
Suicide has been a rich field of philosophical investigation. The main issue regarding suicide is whether it is morally permissible. Howerver, people consider suicide for many reasons. Suicide can be a rational choice. My starting premise is that we cannot survive our bodily deaths. There are various arguments presented both in favour and against suicide. I will review these arguments critically. By discussing of moral and value theories, I will give limited justification that suicide ought to be considered a reasonable option.

摘要
在自殺的討論中，主要論點集中在自殺在道德上是否允許。自殺者的身份有很多，我們不能排除一個人即使離自然死亡有很長一段時間，且他沒有重大傷病的情況下，仍然選擇自殺，我們應該予以自殺者尊重。本文會採取死亡之後，個人就不存在的情況來討論，檢視同意自殺和反對自殺的意見，並說明在道德和生命價值的討論中，有些情況的自殺是具有合理性的，並給予自殺有限的證成。
