Quote:If I say 'it is raining' both I, and the person I say it to, understand that 'it is raining'. The only way to introduce doubt or the demands of evidence is to change the statement. For example, the statement will become 'it might be raining', or the statement might become: 'the person who says "it is raining" may be lying'.
Yes, but there are two problems to consider.
When I say to you "it's raining" I use a codified system of communication and, since you are familiar to that particular system, you understand what I mean.
The same when I say "there is a fire in the building".
And the same when I say "the queen of France is a woman".
But language is not only an exchange of statements within a codified system.
When I say to you "it's raining", or "there is a fire" I am describing a factual situation. The statements are valid within the language system previously chosen, but they are not necessarily true.
Because those statements refer to something that is external to the logic of language. And that is the reason why when I say "it is raining" or "there is a fire" I am causing in you, not only an understanding but also a physical reaction.
There is no difference with the signs that some animals give, when they feel a predator. They understand the signs, but there is something else: a reaction, that has nothing to do with language.
I think you agree that logical system can never reach anything that is not already included and codified within that system.
What I mean by this is: the validity of a proposition has nothing to do with it's truth.
See the third example: "the queen of France is a woman". This is a valid proposition. The predicate/attribute is already in the subject. This could be an analytical proposition. But it isn't. When I say "the queen of France is a woman", I am saying more than that. I am saying" There is a queen in France, and that queen is a woman". And that proposition is valid but false.
But if I say "assuming that there is a queen in France, that supposed queen must be a woman", I am enouncing an analytical proposition.
