This thread is inspired by a discussion in a legal thread about AI where several members have offered diverse opinions about the difference between truth and fact.

It is meant to give everyone a chance to expand on their view of this important subject.

Facts require truth in order to be facts, but truths do not require facts in order to be true. This is why science has been called a child of philosophy, but philosophy has never been called a child of science.

Not at all, facts requires faith for us to accept them, truth is just waiting for us to prove it wrong, again...

I disagree with both members' statements as the situation is rather more complicated than either simplistic view of truth or fact.

Rather than indulge in semantic argument, surely it is better for any user of either vague term to define exactly what they mean by fact or truth, or the relationship betwen them if they need that.

To kick off explanations let me expand on why I think the situation is more complicated.

Both truth and facts are about statements and both require the detail of context to fully express the meaning of a statement. The English language is particularly good in providing the means to express this meaning, whether limited to some specialist use for a particular discipline or in the wider context.

It may or may not be possible to assign a "truth value" to any given statement.

Fir example one of the simplest sentences in the English language is - " Go!"

This statement has no truth value whatsoever.

So truth can be classified as at least either true, or false or no value or indeterminate.

Don't have much time as I have a busy day ( I thought those were over once retired ) but I just had to reply to this.

Facts are global ( apply to everyone - objective ); truth is local ( applies to one person - subjective ).

Diplomatic agreements often involve statements that can be looked at in such a way that the end result gives both parties a different view of what the words can mean. In other words a different view of what both claim to be truth. The process is known as constructive ambiguity.

A true statement is a proposition. As @studiot notes, not all sentences are propositions, like "Get down!" And some only appear to be propositions like Noam Chomsky's "colorless green ideas sleep furiously," because they lack meaningful reference to the world (may be nonsense or highly poetic or what have you). A good starting point (busy day, here, too) is Russell, with his correspondence theory of truth...

He holds that a statement is true if it strictly corresponds to an independent, objective fact. Truth is not determined by usefulness or consensus; rather, beliefs are formed by minds, but their truth hinges entirely on how they align with reality.

On his view, the condition of being true depends on objective fact.

One can trace a lot of modern theory of truth, say the last century, with his correspondence theory as a starting point.

I think it's both very complicated and very simple:

"The limits of my language means the limits of my world." - Wittgenstein

Culture is one of many filters that determine both truth, and to a lesser extent, facts; most of what we think of as objective facts, is via an editor of some sort...

I may well be wrong about this, of course, but, as I see it, the difference lies more in the criterion. A fact must stand up to scrutiny in the wider world and its context. Depending on the language, the statement that is, the truth of it can shift.

The truth about facts are, a lot of them will be wrong in a year or two...

Yes I agree. The Atacama Desert provides a prime example of this, using my earlier comments.

The concept of 'truth' is a language element that obviously bewitches many people. In fact it is just the substantiation of the adjective 'true'. Example:

Of course: both refer to a true linguistical expression of a state of affairs. It says nothing more than that a statement is true. If I use the concept of 'truth', it is more a collection of true statements that are somehow related, e.g. in a murder case (to take the example of @Gees. From this view, the way (s)he uses the concepts of 'truth' here is nonsensical:

The correct description of his example would be:

• It is true that (s)he stands over the shot body of a man (s)he despises, with a gun in his (her) hand

• It is true (s)he did not kill him

• It is true that (s)he was convicted for this murder.

You can replace 'it is true' with 'it is a fact'. Even worse, you can discard of the phrase 'it is true that' completely: one is still saying the same.

And to add: if somebody talks about 'Truth' with capital 'T', then he is making himself important...

And I agree with what @TheVat posted.

Both are linguistic tools to convey ideas.
So let's examine the ideas they attempt to convey.

The word 'fact' indicates to your listener that they can independently verify what you have stated, and they will find agreement.
The word 'truth' is usually stated as 'my truth' or 'I believe to be true', indicating a personal belief, which might not be verified by other's.

No offense, Eise, but there is nothing Philosophical about it; the two terms, much like a hammer and a screwdriver, are defined by their intended purposes.
( although people do use hammers to drive in screws, and screwdriver handles to bash things )

If we have a thread here in the philosophy forum, wouldn't we use definitions proper to that domain? In philosophy, when it's done well, hammers and screwdrivers have their specific purpose.

The sentence "I believe X to be true" is true as a statement of belief, i.e. when the speaker isn't lying, it's an honest report of one's state of mind. X itself, however, is true only when it is a proposition which aligns with reality.

I suggest it would be productive to widen the scope of the discussion.

Consider the statement 'A kiwifruit is delicious.'

This is true for some people but not for others so is not a fact, but a value judgement.

But the statement 'A kiwifruit is a fruit' is true regardless of how it tastes and is a fact.

Which brings me to the observation that English offers the ability to distinguish between Truth, a Truth and the Truth.

Another factor is time.

The statements

Mars is 150 million miles from Earth

Mars is 50 million miles from Earth

Can both be true, but are either facts ?

The statements

Churchill was born in 1874 was true in 1875, but not true in 1873.

Then again there are other ways than comparison with reality to establish veracity.

For instance 'A triangle has three corners' is true by definition.

So the tense of the verb is significant, and can cause confusion in those languages that do not have a present tense of this verb.

It seems to me "facts" are the same to any sane observer, whereas, "truth" is more subjective and limited by one's experiences and knowledge (and perhaps ability to use those to reason in a logical manner).
