Abstract
Reflection on death gives rise to a variety of philosophical questions. One of the deepest of these is a question about the nature of death. Typically, philosophers interpret this question as a call for an analysis, or definition, of the concept of death. Plato proposed to define death as the separation of soul from body. This definition is not acceptable to materialists, who think that there are no souls. It is also unacceptable to anyone who thinks that plants and lower animals have no souls, but can die. Others have defined death simply as the cessation of life. This too is problematic, since an organism that goes into suspended animation ceases to live, but may not die.
