Deep dives

The Utility of Belief in Human Thought

Belief is considered by some thinkers as a misleading category when analyzing human thought processes. The speaker suggests that while belief can serve a purpose in specific contexts, such as religious faith discussions, it fails to accurately reflect how people engage with ideas in everyday situations. For instance, terms like 'I believe' may indicate varying levels of conviction that do not equate to a measurable belief strength. Instead, the speaker argues that thought and inquiry should be led by a focus on explanations rather than beliefs.
