How "inter subjectivity" is supposed to work? Do you read the mind of other people?
What is "evidence" exactly?
I'm asking here whether you think you know that the Moon exists... So, what evidence do you personally have that the Moon exists?
Does this mean you think it's not legitimate for you to claim to know that the Moon exists?
Does this mean you think it's not legitimate for you to claim to know that you are in pain whenever you are in pain?
Sorry, you're no making sense here. Could you clarify?
Could you or anyone falsify my claim that I'm thinking about going for a walk?
Could you or anyone falsify my claim that I know pain whenever I feel pain?
Does anyone knows anything at all?
Ok, let's assume we all know a few things.
For example, let's assume it's a fact that John knows that the Moon exists.
Given this, is it at all possible do you think to falsify the fact that John knows that the Moon exists?
And presumably we don't know all swans that have ever existed...
But more importantly for falsification, we presumably don't know any swan that will only exist in the future.
So, how could we possibly claim to know things like "all swans are white"?
