I don't think so. Or I would like to know of a system or approach that supports it.
...but we can also usefalse propositions in good reasoning. Since a false conclusion cannot be logically proved from true premises, we can know that if the conclusion is false then one of the premises must also be false, in a logically valid argument. A logically valid argument is one in which the conclusion necessarily follows from its premises. In a logically valid argument, if the premises are true, then the conclusion must be true. In an invalid argument this is not so. "All men are mortal, and Socrates is a man, therefore Socrates is mortal" is a valid argument. "Dogs have four legs, and Lassie has four legs, therefore Lassie is a dog" is not a valid argument. The conclusion ("Lassie is a dog") may be true, but it has not been proved by this argument. It does not "follow" from the premises.
Now in Aristotelian logic, a true conclusion logically follows from, or is proved by, or is "implied" by, or is validly inferred from, only some premises and not others. The above argument about Lassie is not a valid argument according to Aristotelian logic. Its premises do not prove its conclusion. And common sense, or our innate logical sense, agrees. However, modern symbolic logic disagrees. One of its principles is that "if a statement is true, then that statement is implied by any statement whatever." Since it is true that Lassie is a dog, "dogs have four legs" implies that Lassie is a dog. In fact, "dogs do not have four legs" also implies that Lassie is a dog! Even false statements, even statements that are self-contradictory, like "Grass is not grass," validly imply any true conclusion in symbolic logic. And a second strange principle is that "if a statement is false, then it implies any statement whatever." "Dogs do not have four legs" implies that Lassie is a dog, and also that Lassie is not a dog, and that 2 plus 2 are 4, and that 2 plus 2 are not 4.
This principle is often called "the paradox of material implication." Ironically, "material implication" means exactly the opposite of what it seems to mean. It means that the matter, or content, of a statement is totally irrelevant to its logically implying or being implied by other statements. Common sense says that Lassie being a dog or not being a dog has nothing to do with 2+2 being 4 or not being 4, but that Lassie being a collie and collies being dogs does have something to do with Lassie being a dog. But not in the new logic, which departs from common sense here by totally sundering the rules for logical implication from the matter, or content, of the propositions involved. Thus, the paradox ought to be called "the paradox of wort-material implication. The paradox can be seen in the following imaginary conversation:
Logician: So, class, you see, if you begin with a false premise, anything follows.
Student: I just can't understand that.
Logician: Are you sure you don't understand that?
Student: If I understand that, I'm a monkey's uncle.
Logician: My point exactly. (Snickers.)
Student: What's so funny?
Logician: You just can't understand that.
The relationship between a premise and a conclusion is called "implication," and the process of reasoning from the premise to the conclusion is called "inference" In symbolic logic, the relation of implication is called "a tnith-functional connective," which means that the only factor that makes the inference valid or invalid, the only thing that makes it true or false to say that the premise or premises validly imply the conclusion, is not at all dependent on the content or matter of any of those propositions, but only whether the premise or premises are true or false and whether the conclusion is true or false.
...Logicians have an answer to the above charge, and the answer is perfectly tight and logically consistent. That is part of the problem! Consistency is not enough. Logic should be not just a mathematically consistent system but a human instrument for understanding reality, for dealing with real people and things and real arguments about the real world. That is the basic assumption of
the old logic.

Then there is the opposite attack on thought: that urged by Mr. H.G.Wells when he insists that every separate thing is "unique," and there are no categories at all. This also is merely destructive. Thinking means connecting things, and stops if they cannot be connected. It need hardly be said that this scepticism forbidding thought necessarily forbids speech; a man cannot open his mouth without contradicting it. Thus when Mr. Wells says (as he did somewhere), "All chairs are quite different," he utters not merely a misstatement, but a contradiction in terms. If all chairs were quite different, you could not call them "all chairs."
The essential thing is contingency. I mean that one cannot define existence as necessity. To exist is simply to be there; those who exist let themselves be encountered, but you can never deduce anything from them. I believe there are people who have understood this. Only they tried to overcome this contingency by inventing a necessary, causal being. But no necessary being can explain existence: contingency is not a delusion, a probability which can be dissipated; it is the absolute, consequently, the perfect free gift. All is free, this park, this city and myself. When you realize that, it turns your heart upside down and everything begins to float...
That's not the same as "(A implies B) and (A implies not-B)" -- that'd be "(A implies (B and not-B)).
(3) If praying induces experiences for a biological reason, then prayer-induced experiences are not observations of reality but hallucinations.
It is comical that God intentionally bothers to mysteriously appear to random people at random times and yet stays quiet when a little Nepali child is being ripped to shreds by a Bengali tiger. Curing children from cancer is somehow a violation of free will, but turning a little lump of blood into liquid like in the "miracle" of Saint January doesn't violate free will at all, does it?
Are you suggesting that we ignore scientific approaches that aren’t ‘mature’?
political prejudice, not philosophical prejudice.
That is not the result, it is the condition from within which we judge.
But that is not all he is doing. Aristotle says the rhetoric is the counterpart to dialectic. The sophists are not the only ones who attempt to persuade us, and it is quite evident that myths can be persuasive. In some causes they can be so persuasive that there are those who believe them to be the truth.
Socrates turns from the problem of the limits of sound arguments to the soundness of those who make and judge arguments.
And yet, he does care. The answer to that question matters to him
It may prevent you from acting unjustly or wrongly accusing others of acting unjustly.
If someone claims to know what is the Good, do you know, can you know, that she knows what is the Good?
There seem to be many things that all (or at least most) people take to be good. Does that consensus amount to knowing what is the Good, or what goodness universally consists in, its essence?
But Hume and Kant showed there is no cause and effect - they are just constructions that might have nothing to do with the world in itself.
(Phaedo 97b-d)
Having some idea of what is better is not knowing what is better. It is an opinion or belief. He could be wrong:
It is the question of what is better that is at issue. It involves deliberation about opinions about what is best
Socrates never abandons his pursuit of the good. It is not for him an intellectual puzzle to be solved. It is a way of life. The pursuit of the good is good not because the good is something we might discover. The pursuit of the good is ultimately not about knowing the good but about being good.
There are things that he thinks it is better to believe to be true even if they are not. The philosopher may object that she is interested in what is true, not in what seems to be true, and certainly not in making it seem to be true. But the truth is, there are things that we do not know to be true. Rather than this leading to nihilistic skepticism, in the absence of knowledge Socrates asks us to consider what it is that is best for us to believe as true. This not for the sake of the truth but for the sake of the soul.
Making philosophical music requires both reason and imagination. Both arguments and stories, including the stories we tell ourselves. Stories come to us chronologically before reasoned arguments and logically after reasoned argument comes to its end. I will end this with another question: Has the philosopher outgrown the need for stories?
The logoi of all things known by God before their creation are securely fixed in God. They are in him who is the truth of all things. Yet all these things, things present and things to come, have not been brought into being contemporaneously with their being known by God; rather each was created in an appropriate way according to its logos at the proper time according to the wisdom of the maker, and each acquired concrete actual existence in itself. For the maker is always existent Being, but they exist in potentiality before they exist in actuality It is impossible for the infinite to exist on the same level of being as finite things, and no argument will ever be capable of demonstrating that being and what is beyond being are the same, nor that the measured and immeasurable can be put in the same class, nor that the absolute can be ranked with that which exists in relation to other things, nor that that which has nothing predicated of it and that which is constituted by predication belong together. For all created things are defined, in their essence and in their way of developing, by their own logoi and by the logoi of the beings that provide their external context. Through these logoi they find their defining limits.

'All beings, by the logos by which they were brought to being and exist, are perfectly firm and immovable; by the logos of things seen as related to them, by which the ordering (otKovoµia) of this universe is clearly held together and conducted, all things move and admit of instability.

What does Aristotle say about this? Is there a term, or an ethical condition, that can describe a person who has "fallen into vice" but not only doesn't know it, but is convinced that they desire the exact opposite?
I don't know . . . possibly I've hung out with the wrong people but the idea that "humans necessarily want to be happy" is extremely implausible to me. Here, for instance, is a person named Pat. Pat suffers from a variety of psychological, physical, and spiritual maladies that produce a kind of chronic frustration, depression, resentment, and lack of ease -- in short, what we mean by "unhappiness." If you ask Pat if they "want to be happy," the answer you will get is: "Nonsense. What you call 'being happy' is for sheep. I operate on a higher plane. Of course I'm miserable, but that is what happens when a person of true intellect sees the world aright. I wouldn't trade one minute of my unhappiness for a fool's paradise of Smiley Faces." Pat, you could say, would rather be Happy (their sense) than happy, but surely that's stretching what "happy" means. Let's face it: Pat just doesn't want to be happy, and they can give you their reasons why.
