13. The Problem of Other Minds âThose look like my students, but how do I know they have minds,â thought Mrs. Robin. Notice Mrs. Robin has a mind.
14. The Problem of Other Minds âMy innate knowledge doesnât tell me they have minds. There is no sensory experience that tells me they have minds. And thereâs no self-evident proposition according to which they must have minds. But I do believe they have minds. I have a number of beliefs I would have to doubt if they had no minds.â
15. The Problem of Other Minds âI will apply the Principle of Belief Conservation. My Proposition P will be that they have no minds.â
16. The Problem of Other Minds âFirst I will ask myself if I have other beliefs that I would have to doubt if they did not have minds. I think I do. What are they?â
17. The Problem of Other Minds âIf they had no minds, I would doubt that they had feelings. If they had no minds, I would doubt they can make choices on their own. If they had no minds, they wouldnât laugh at my jokes.
18. The Problem of Other Minds âNow I will ask myself, âDo I have any good reason to doubt those things I just listed as beliefs?â No, I canât really think of any good reason to doubt that my students laugh at my jokes, have feelings or make choices.â
