What happened in the 400 years of the Dark Ages that made philosophical inquiry cease?

The term "Dark Ages" refers to a period in European history, roughly from the 5th to the 10th century, characterized by a decline in cultural and intellectual activity following the fall of the Roman Empire. During this time, societal instability, invasions, and a focus on survival led to the prioritization of practical concerns over philosophical inquiry. Additionally, the rise of the Christian Church established a theological framework that often discouraged questioning and emphasized faith over reason, further stifling philosophical thought. However, it's important to note that this characterization is debated, as intellectual activity continued in other regions, particularly in the Islamic world and parts of Asia.
