Final answer:
Stoicism is the early Greek philosophy that maintained humans should live in agreement with nature (logos), which is considered a rational principle guiding the universe.
Step-by-step explanation:
The early Greek philosophy that emphasized living in harmony with nature (logos) is known for its Stoic tradition. Stoicism was founded by Zeno of Citium in the early 3rd century BCE, but many of its practitioners, including the first Stoics, were of Semitic descent and likely drew upon the Jewish thought at the time, which relates to Logos. This connection is intriguing given that the Stoics believed the universe was guided by a divine Logos, akin to the rational and organizing principle that characterizes the universe.
Importantly, Stoicism argues that living in accordance with nature and reason is essential for human flourishing. This philosophical school believed that the world operates according to rational principles, or logos, and maintaining humans should align their lives accordingly. This perspective encourages individuals to develop virtues and live ethically, accepting life's events as manifestations of natural order.
