Re: What is truth?
I'd rather hear how one might argue against my points directly then to require 'homework' on my own that I already do. What are you asserting or denying, agreeing, or disagreeing to? Or is this even a response to me?raw_thought wrote:http://plato.stanford.edu/entries/truth-coherence/#Cri

Re: What is truth?
Validity is the part the determines HOW the inputs are connected appropriately. This HAS to be minimally 'true'. I definitely did not assert this in isolation of 'soundness'. That is, validity is NOT a sufficient condition. Nor is the 'soundness' of the premises without the connectivity making them valid. The 'fitness' must require the relationship of 'coinciding' values in some domain these factors share collectively of one another, regardless of whether we could or could not directly determine.raw_thought wrote:raw_thought wrote:BTW, Truth has a specific definition.

[* All that 'validity' means is that given true premises, the conclusion must also be true. The incompleteness is due to "W. Bush" as not being mentioned in the argument. The conclusion is just a restatement of at least those things derived in the premises. This allows "inductive arguments" to be a form of argument too. You could also make the first one 'true' to our world by defining "Martian(s)" as something 'fit' in our world.]

Re: What is truth?
Indeed. It all depends on what truth you want to push.raw_thought wrote:However, even then "truth" is a correspondence ( ironically and this is interesting as I mentioned previously the correspondence theory of truth has problems) between a proposition and reality. For example, I can lie and say that I am sad. My statement is not the truth because it doesn't correspond to my state of mind.Hobbes' Choice wrote:That's the normative description. But truth is used validly to comply to a lesser standard too' such as religious truth, moral truth. You might even say of literature that it has a truthful account of friendship or human relations, when it is actually 100% fiction.raw_thought wrote:" so: truth (the true[ful] statement) is that which describes what is real."
Henry
So you finally agree that truth does not = reality. Truth is when a statement describes reality.
Truth is in fact when one statement or account complies with your view of the world.
It is certainly not a simple matter of definition.

Re: What is truth?
Bullshit. Validity refers to correct inference. An argument is valid if the conclusion follows from the premises and invalid if not. An argument can have true premisses, a true conclusion, but be invalid(if the conclusion doesn't follow). It can also have true premisses, a false conclusion and be invalid(must be in that case). Thus, what you say above isn't correct...Scott Mayers wrote: [* All that 'validity' means is that given true premises, the conclusion must also be true.]
Given true premisses and an invalid argumentative form, the conclusion is not necessarily true. The only time a conclusion 'must' be true is if it follows from true premises(if the argument has both true premisses and a valid argumentative form).

Re: What is truth?
Truth has more than one specific definition.raw_thought wrote:BTW, Truth has a specific definition. For example in logic truth does not = validity.
In some logic(s)... truth is often taken to have much to do with coherence(consistent word usage accompanied by valid reasoning sprinkled with an apparent lack of self-contradiction). Following the laws of thought/belief. Those shed light on some things, but not all. Other logics deny the law/principle of ambivalence. Some attempt to deny the law of self-contradiction. Some deny both.
All logical argument necessarily presupposes correspondence by virtue of presupposing the truth of the premisses. Logic aims to preserve the presupposed correspondence by virtue of following the rules of correct inference(valid argument/reasoning).
The premisses lack correspondence.Here is a valid argument that lacks truth.
1. All Martians eat snakes.
2. Bob is a Martian.
3. Therefore, Bob eats snakes.
Arguments aren't the sort of thing that can be true. The premisses are both true. The conclusion is invalid because it does not follow from the premisses.Here is a true but invalid argument.
1. Carter was president.
2. Nixon was president.
3. therefore, W. Bush was president.

Truth is almost always false, from a different POV.
Trump considers that immigrants are criminal rapists being parasitic on US society.
Others could say that immigrants have founded the US and have in all cases made the US what it is today.
Both statements are true.

They correspond to each other. If all As are Bs and C is an A then C is a B.
The fact that All Martians do not eat snakes and that Bob is not a martian is an issue of truth not validity. The above argument is valid but not true.

It is also true that immigrants have founded the US. Thomas Paine migrated to the US from England and practically invented the US. QED.
