Epicureanism
Epicurus, bronze bust from a Greek original, c. 280ā270 bce; in the Museo Archeologico Nazionale, Naples.
De rerum natura (On the Nature of Things) is a didactic poem by the Roman philosopher Lucretius that serves as the most comprehensive extant exposition of the physical theory of Epicurus.21
The work is divided into six books that detail the Epicurean worldview:
- Books I and II: Establish the principles of an atomic universe, arguing that matter consists of infinite, indestructible particles moving through a void.21
- Book III: Explains the atomic structure of the soul and argues for its mortality, concluding that death is nothing to fear.21
- Book IV: Examines the mechanics of sense perception, thought, and bodily functions.21
- Book V: Describes the creation of the world, the evolution of life, and the development of human society.21
- Book VI: Explains natural phenomena, such as thunder and lightning, and concludes with a somber depiction of the plague at Athens.21
Ultimately, Lucretius aimed to liberate humanity from the fear of gods and death, advocating for a life focused on achieving maximum pleasure and minimum pain through philosophical understanding.1
