Final answer:
Sage philosophy is primarily based on oral tradition. Sages articulate the received wisdom of their culture while seeking a rational justification for their beliefs. This tradition can be seen in various cultures, such as Africa and ancient Greece.
Step-by-step explanation:
The tradition of sage philosophy is primarily based on oral tradition. In Africa, for example, Henry Odera Oruka conducted interviews with tribal Africans who were identified as sages by their communities. These sages expressed complex philosophical ideas through their sayings and demonstrated a rational method of inquiry into the nature of things.
They maintained a critical distance from their culture while articulating the received wisdom of their tradition. Similarly, in ancient Greece, the earliest philosophers were known as sages, and their ideas were transmitted orally. The sage tradition provides a glimpse into philosophical thought in action, showcasing a skepticism of traditions and a commitment to rational reasoning.
