Passage Summary: The folklorist argues that speaking is better than writing because it keeps your brain sharp and discards useless data, while writing makes people lazy and creates confusing amounts of information.

Conclusion: Oral traditions are frequently better than written ones.

Reasoning: Oral traditions improve memory and naturally filter out irrelevant information, whereas written traditions can lead to mental laziness and information overload.

Analysis: The folklorist moves from descriptive facts about memory and information volume to a normative judgment that one tradition is 'preferable.' To justify this, we need a principle that bridges the gap between these specific benefits and the concept of being better. Look for a principle that values memory retention and the elimination of irrelevant data as the primary criteria for judging a communication medium. The argument assumes that the 'sluggishness' and 'confusion' associated with writing are significant enough to outweigh any of its potential benefits.
