Rational belief

Summary

The speaker explores the complex nature of knowledge and truth, suggesting that while complete knowledge may be unattainable, rational belief based on evidence and sound reasoning is essential. Referencing Bertrand Russell, the speaker emphasizes that what truly matters is not just what you believe but why you believe it. Rationality is about proportioning your beliefs to the evidence and reasons available, and being open to revising your views when new evidence emerges. Ultimately, rational thinking calls for responsibility, questioning convenience, and relying on reason to guide our beliefs.
