    I am well aware of what he wrote. But his English is far from exemplary and I tried to explain what he probably meant.

    I know my English is far from exemplary but if I wanted to kill myself, I would climb up to your ego and jump down to your IQ level. 😀

    So someone tries to help you out and you insult him. I never cease to be bemused by how unpleasant (self proclaimed) Christians turn out to be when questioned. It suggests that I am not mistaken in choosing to take your words as presented and let dig your own way out of your own holes.

    It's a joke lighten up. It was aimed at his self proclaimed mind reading abilities.

    Also funny how you manage to evade questions.

    It may have been a joke, but it was clearly also a deliberate insult. And I have not claimed to have mind reading abilities making your claim I 'self proclaimed' them a blatant lie.

    Is that a fact? If so I guess it's not true then by your own admission.

    You guess what is not true?

    Oh yes I forgot only you are allowed to insult people about their reading comprehension etc.

    And I have not claimed to have mind reading abilities making your claim I 'self proclaimed' them a blatant lie.

    Oh so when you were saying you "knew" what I meant, and when you said I insulted you "deliberately", you were not claiming to be a mind reader?

    Whatever you stated as a fact because you stated that a fact is not true.

    "If A then A" is a statement of logic but in what sense is it true?

    I am not convinced either that we can use logic to show truth, though I do see we can use it to make inferences about statements - but that is redundant really and not helpfu ...[text shortened]... ueen of England may (or may not) be found and the truth of my statemenet established or refuted.
    I've got a slight difference with you here. Classical logic is a language, and assigning the status true or false to it is as silly as asking if the moon is true - ignoring the meaning of true used in carpentry where it more or less means straight (which is where we get the word true from) - so far we agree. Classical logic is expected to preserve truth. So if I have "if A then B" and A is true then we expect B to be as well, independently of what A and B are. Logical statements such as "if A then A" are tautologies and they are true, unconditionally so, but are trivial.

    The "truth test" in logic, at least classical logic, isn't connected with usefulness but whether one can deduce a false statement. The nonsense statement "If I am a giraffe then the planet Mars is green." is true, because one cannot make an incorrect deduction from it. I'm not a giraffe, so nothing can be concluded about what colour Mars is and Mars is not green so one can correctly conclude that DeepThought is not a giraffe. Summary, usefulness isn't a criterion for truth, something can be nonsense or trivial, but nevertheless true.

    By 'true' do you mean 'universally true'?

    By 'true' do you mean 'universally true' or 'true according to your subjective opinion'?

    No I mean true. Either it is true or false, there is no universality criterion.

    I would say they require the prior foundation of truisms.
