    That is also a proposition - one with a different logical subject and predicate.

    You are mixing up a couple of things: True claims and false claims, truths and lies, the science of necessary inference called logic and what is "reasonable" ........ confusing.

    Nemesio: " That's why we call it faith: because it defies logic and reason, and we believe it anyway."

    ????? ..... If this is faith then I do not have faith.

    The Roman-Catholic religion does not contradict logic or reason in any principal way.

    Er. Doesn't the answer have to be accurate for it to be a proposition?

    That is, if I said 'Yes' to your proposition, shouldn't I be able to
    demonstrate it (which, of course, cannot be objectively done)?

    It may be a coherent sentence grammatically, but it does not have
    a coherent answer (because subjective opinions do not have truth
    values).

    ...[text shortened]... es.

    Would you like me to put "Pepsi tastes better than coke" in logical propositional form?
    You're just randomly throwing together bits and pieces of phrases that you've seen used over at Christian Logic, such as 'predicate' and 'declarative', and hoping that what comes out either convinces me that you are correct or confounds me to the extent that I cannot construct an intelligible response.

    Seriously. Not a single sentence in your post both makes sense and is correct.

    For my amusement, go ahead put it in "logical propositional form." This should be fun.

    The discussion and instances about taste are very confusing.

    Well, Ivanhoe, a Moslem, Mormon, Jew and atheist (among
    others) would disagree with this. The first three would maintain
    that their notion of 'natural law' was the reasonable one and
    that yours is unreasonable.

    And, so, faith conflicts with reason all the time. It's only within
    the context of a single faith that it might not. The second
    you expand to a ecumenical notion of faith, you find conflicts
    left and right.

    Nemesio

    Edit: so the subject should read 'My Roman Catholic faith never
    conflicts with reason.'

    If you are such an expert then why do you bring in these instances about "taste", which can only add to the confusion.

    Because Coletti tried to introduce an absurd notion of opinions as being beliefs. It would be irresponsible of me as Christian Logician to allow him to wallow in this error.

    If you look upon things the way you do one might also claim that science defies logic and conflicts with reason all the time. For instance the Theory of Strings and all these mindboggling theories of which it hasn't been proven (yet) that they are true. I simply do not grasp what you are trying to say.

    In my opinion one part of the problem is that you do not reason from a certain stance or point of view. The only point of view that I can detect on your side is the stance that my point of view must be incorrect.

    If something is unjustified, that means you lack the means to

    unjustified claim. Would you call this an opinion? I wouldn't.

    How about this? 'Vanilla tastes better than chocolate.' C ...[text shortened]... 'educated
    guess.' Educated guesses (lacking a solid reason) are not 'opinions.'

    Nemesio
    Good points. I am compelled to say that an opinion usually have basis or support for one to believe them true.

    I think we'd agree that opinions are weaker than knowledge - even if they have some sort of support - so in the definition of knowledge (justified true belief) the justified must be stronger than the support given to opinions.

    I don't know about educated guesses - these seem like opinions also.

    An opinion is a belief also. It usually connotes a belief with less than unquestionable support. Usually they are similar to the "which tastes better" example which may be true for one person and false for another. Opinions are propositions one hold true depending on other premises.

    So they are still unjustifed in the sense of "justified true belief" is knowledge.

    I would have to pimpslap anybody who would agree with you about this.

    Opinions and knowledge do not lie on the same spectrum. They are different beasts altogether. One cannot have opinions about factual matters. One cannot have knowledge of subjective matters, but only knowledge about subjective claims, such as "It is Nemesio's opinion that..."

    You can't know that chocolate is a good tasting ice cream.
    You can't opine that ice cream melts, or that it doesn't melt.

    Ivanhoe can't opine that I'm white.

    Sure they do! A subjective proposition is subjective because the true/false values is subject to other premises which are not universally accepted as true or false.

    "The golden gate bridge is orange." Well when I looked at it last, it looked red to me. And some people are color blind. And then you can define color by some measure of a light spectrum. So the truth of "the golden gate bridge is orange" can is subjective - depending or other premises that may not be agreed upon.

    Coke taste better than Pepsi. If we are talking about my taste - this is true. So it is a proposition, but it is not knowledge. To be knowledge it must be universally true, not subjectively.

    All propositions are either true of false - but not all propositions constitute knowledge. A proposition must be universally true to be knowledge. Opinions are true subjectively.

    I always thought that 'reasonable' meant something proveably true,
    or at least very likely to be true.

    What do you think 'reasonable' means, Ivanhoe?
