On Life and Death

"On Life and Death" is a work of the Greek philosopher and scientist Aristotle, which was included in the collection Parva Naturalia ("short treatises on nature"). The collection consists of seven essays discussing various natural phenomena related to the body and soul.
 The culmination of Aristotle's "Parva Naturalia" is the definition of the stages of the life cycle, from the birth of a new living being to death.
