From: wex@ittvax Lorenzo makes the claim that the "joy, pain, and intelligent achievement" of life are the most fundamental items (discussed so far). That's all well and good, except for one thing: I (and all other humans besides yourself) haven't the foggiest idea what you are \actually/ feeling. All we can do is get a distorted impression from your words and actions. The mental world is (at least for the moment) a completely private one; it would seem, therefore, to be difficult to judge the quality/worth of ANY life on something that is not even observable, let alone measurable. Wexelblat's complaint here is suggestive of solipsism. Perhaps I'm the only sentient being in the world and the rest of you are mindless automata (AI people, please forgive this colloquial expression), but I do not (and can not) believe it. Similarly, perhaps the rest of you are lying when you (for example) tell me you're happy. That such deception is possible is the point, I take it, of Wexelblat's emphasis on what you \actually/ feel VS. my impression based on your words and actions. Such systematic deception is almost as hard to believe in as the solipsistic thesis was. Like solipsism, the proposition that others are deceiving me about their joys and pains is hard to reconcile with other beliefs of mine (some of which are based on observation and measurement). Even in the case of any individual (politicians and salesmen excepted), the hypothesis that s/he is constantly deceiving me runs aground on the probability that s/he has no motive for doing so. Therefore, I see no obstacle to my reasonably believing that someone's life is valuable (valuable according to Sadun's criteria). "[Nobody besides yourself has] the foggiest idea what you are \actually/ feeling." This is either false or irrelevant. If the word \actually/ is merely for emphasis, such that it does not affect the reference of the phrase it is in, then the statement is relevant but false. Suppose I believe that you are happy (only) on the basis of your actions. That doesn't show that I should be skeptical about whether you are happy, any more than the fact that I believe there's a chair here (only) on the basis of certain of my sensations shows that I should be skeptical about whether there's a chair here. On the other hand, if the word \actually/ is crucial in the statement (for example, if it means "what you are actually feeling, apart from what you act and talk like you're feeling"), then the statement is true but irrelevant. As I have argued, what people act and talk like they're feeling is usually the same as what they're feeling. Sometimes not -- our evidence about other minds can be misleading, and our judgements fallible. But the same applies to our beliefs about reality. --Paul Torek U of MD, College Park P.S.
