2735 Could you have a single belief on its own? [Audi,R]
11. Knowledge Aims / B. Certain Knowledge / 1. Certainty
2736 We can make certain of what we know, so knowing does not entail certainty [Audi,R]
11. Knowledge Aims / C. Knowing Reality / 2. Phenomenalism
2721 If you gradually remove a book's sensory properties, what is left at the end? [Audi,R]
2722 Sense-data theory is indirect realism, but phenomenalism is direct irrealism [Audi,R]
