Epicurus believed that acknowledging and accepting our faults is crucial for attaining tranquility, emphasizing a collaborative journey with others. He stressed the importance of understanding science to avoid superstitions, being ahead of his time by proposing the existence of atoms and void, denying a divine creation of the universe unlike the Stoics. Stoics, in contrast, believed in a providential universe where everything happens for good as designed by a divine being, influencing their views on misfortune and suffering. Epicurus viewed the world as materialistic and physical, attributing the existence of living beings to the motion of atoms and happenstance.
