- But then, the "other people" "seem" to exist, so their testimony would
- only be "seeming", too.
-
- But if you're interested in collective Solipsism, try reading Fichte
- or one of his Idealist friends.

- There is none. It is rooted in how logic works. Given a set of premises,
- you can always come up with a conclusion. But you cannot, given some
- conclusion, say that it must stem from one uniquely determined set of
- premises. So if you say that your perceptions (conclusion) must by
- necessity come from the world as you think it is, since the existence
- of such world would yield the given perceptions (premises), you have
- actually committed a logical fallacy. This, the sceptic knows, and
- will use with full force in argument that he will necessarily win,
- unless you resort to the "cheap tricks" of saying:
-
- 1. Do you mean I don't know you exist, or that you don't know that
- I do exist? [You are here tyeing cognition to a person, and not
- just debating it in abstraction.]
-
- 2. But _I_ know this world exist, positively. Or would you claim
- otherwise? Can _you_ know that _I_ cannot know?
-
- 3. So, you're just telling me you have a hard time figuring reality
- out, do you? Well, I could tell you a lot, since I _know_, but
- I really don't intend being your psychiatrist. Sorry.
-
-
- What has happened is that you reversed the situation.
-
- However, this is useful only for debate with people who have that
- malicious smile when they tell you "nothing is certain!", in that
- you simply feed them their own medicine. It can hardly convince
- an honest and thorough inwardly-seeking person who really wants to
- figure things out, as you see at the beginning of my answer.
