    ↪unenlightened But for an inductive argument, its truth value is neither 100% true or 100% false but somewhere in-between.Devans99

    No. There is nothing between empty and not empty, and there is nothing between true and false. What is not 100% is certainty, but a pocket that is 99% empty is not at all an empty pocket.

    Absolute denotes 100% certainty so it is a valid qualifier to use with 'truth'.

    Yes Absolute refers to certainty...

    so it is a valid qualifier to use with 'truth'.Devans99

    So it is not a valid qualifier of truth.

    Our certainty can be more or less, and maybe absolute or maybe not , but it is certainty of truth that is or isn't absolute, not truth itself.

    Of course, we can make new rules and give new mearnings to terms. And in such terms, with such a logic, you can be right. But fuzzy logic is not the logic of our ordinary speech. If you want to talk in that way, then you have to do it consistently; I think you need to get your head around 2-valued logic before you tackle infinite valued.

    very great or to the largest degree possible'

    When we say 'absolutely true' we mean 'absolutely certain to be true'... it's just implicit that the qualifier absolute applies to 'certain to be true' rather than true on its own. It's just an abbreviation.

    But fuzzy logic is not the logic of our ordinary speech.unenlightened

    Yes it is. 99% of stuff we do in our everyday lives is based on induction (so therefore fuzzy rather than boolean logic) - should I cross the road? Did not get run down last time... induction. So when we use terms like absolute truth we are referring to the % inductive likelihood of something being true.

    I only read the question. The problem is in the question.

    Absolute truth exists. Clouds bring the rain is an absolute truth. It is true as long as people watch the clouds waiting for the rain. That does not mean that it will rain. An absolute truth is what we can do. Dancing to bring the rain is an absolute truth, you can do it. That does not mean it will rain. We can talk about certitude but it does not mean we have to do it just because one is more certain than the other. If you take numbers, 1+1=2 is an absolute truth for people who know it. But in nature you have no numbers. You can add one potatoe to another one and say it is two potatoes. That is true only for you.

    The problem is in the question. The truth is relative to a community, the one that watch the clouds and the other that dance. What is true in one is not true in the other one.

    True, truth. Two different words meaning two different things. Start there.tim wood

    Truth is a fact or actuality.

    True, as the way most people seem to use the term, is the degree of accuracy some representation (like a statement) is to the truth.

    The philosophical definition of "true" relates to the logic of some argument.

    What could ever be absolute truth?

    How could we ever know whether the 'laws' of physics we discover will remain accurate tomorrow or in 1 billion years?

    How could we ever know whether the beliefs that we hold now won't change in the future?

    How could we ever know whether something that we deem to be absolutely true won't be contradicted by something we hadn't imagined or thought about?

    There are things we believe, there are appearances, there are things that seem to be the case sure, but absolute truth? It seems more an ideal we try to reach than something we could ever have.
