Epicurus was an ancient Greek philosopher and one of the prominent philosophers in the Hellenistic period. He was the founder of the school of philosophy called Epicureanism. World is still unknown to the majority of his work as there are only few fragments and letters left out of the 300 original works of Epicurus. The most of Epicurean philosophy was known to the world through his followers and commentators.

The basic purpose of Epicurean philosophy was to acquire a happy and tranquil life, which was characterized by ataraxia which was complete freedom from worry and aponia, or absence of pain. One more feature required for the attainment of happy life was to live a self-sufficient
life surrounded with friends. According to him, pleasure and pain are the measures of good and evil and death is the end of body and the soul, hence there is nothing to fear. He taught that the Gods couldn't punish or reward humans and man should not worry about life. He further taught that universe is infinite and eternal and atoms are responsible for events that took place in the world.

Epicurus's philosophy combines a physics based on an atomistic materialism with a rational hedonistic ethics that emphasizes moderation of desires and cultivation of friendships. His world-view is an optimistic one that stresses that philosophy can liberate one from fears of death and the supernatural, and can teach us how to find happiness in almost any situation. His practical insights into human psychology, as well as his science-friendly world-view, gives Epicureanism great contemporary signficance as well as a venerable role in the intellectual development of Western Civilization.

Epicurus was a most voluminous writer. According to Diogenes Laƫrtius he left 300 volumes. Among others he had written 37 books on natural philosophy, a treatise on atoms and the void, one on love, one on choices and avoidances, another on the chief good, four essays on lives, one on sight, one on touch, another on images, another on justice and the other virtues, etc. From all these works there have come down to us three letters and a number of detached sentences or savings, preserved by Diogenes Laƫrtius in his life of the philosopher.

Epicurus suffered from kidney stones and finally succumbed to it in 270 BCE. He was 72 years of age when died. He had no heirs or sons as he never married in his life
