thanatagogy n (Greek thanatos, death + Greek agein, to lead; cf pedagogy, demagogy, mystagogy) Ð initiation into death, preparation for dying. Thanatology is the study of death and dying; thanatagogy is a practical branch of this knowledge. The Egyptian "Book of the Dead" is the most ancient manual in thanatagogy. For Plato, philosophy is thebasis of thanatagogy. To study philosophy is nothing but to prepare oneself to die.by Mikhail Epstein November 07, 2003
