Oh, I thought you had it. I haven't mixed up my definitions of 'factual assertion' and 'fact' (true factual assertion). It's a factual assertion that's falsifiable. But a true factual assertion is obviously not falsifiable, because it's true - it's a fact. I don't understand why this is so hard. But I'm happy to leave it there. Thanks.
It is hard because your use of the words 'fact' and 'factual' seems very disconnected and causes confusion.
You have repeatedly said "I define a fact as a true factual assertion". Which is clearly an indication that you recognise both "true factual assertions" and "false factual assertions". And it is clear that a "false factual assertion" is NOT a fact, whereas a "true factual assertion" is a fact.
The word 'indication' puzzles me. I've stated very clearly that factual assertions may be true or false. I use the word 'factual' to characterise assertions that make factual claims, and to distinguish them from assertions that don't make factual claims, which I call non-factual assertions.
So 'assertions' is the set containing two kinds of assertion: factual assertions and non-factual assertions. And 'factual assertions' is the set containing true and false factual assertions. (And the word we use to name a true factual assertion is 'fact'.)
And so I am particularly curious about your use of the word "factual" in the sentence "false factual assertion".
I hope the above clears this up.
This is as far as I have gotten linguistically. Now, in order to understand your meaning I am asking you to give me an example of a 'true factual assertion' and an example of a 'false factual assertion'.
True factual assertion: the earth orbits the sun. (This is a fact.)
False factual assertion: the sun orbits the earth. (This a factual assertion, because it claims something about a feature of reality. But it's false.)
And I am still no closer to understanding whether my claim (There are 9 planets in the Solar system) a "true factual assertion" or a "false factual assertion" ?
I explained this in one of my recent comments. By all means quote my explanation and show why it's unclear - in which case I'll humbly apologise.
