It says reasonable precisely because reason does not reduce to mere logic. Otherwise it would have said logical. — Pantagruel
I don't understand. Are you saying that there are times in our lives where we do things without having an experience? Are you saying that you spat out something in your mouth for no reason at all?There must've been a time in your life when you put something in your mouth and immediately spat it out. — TheMadFool
Again, what does survival mean? Why would it only apply to carbon-based systems and not silicon-based systems? Seems to me that you have a limited scope/definition of life and survival - an anthropomorphic one.Pain is necessary for our survival for it's the only means by which we detect harm/injury. That doesn't mean that a different method of detecting harm doesn't exist. — TheMadFool
:lol: What did you attempt to illustrate if not the conclusive nature of dialectic logic? Or are you saying that your illustration is just scribbles and isn't about anything?Au contraire. It was a perfectly valid choice of a dialectical problem. Itwas never intended to be conclusive, only illustrative (as I have repeatedly pointed out, yet you inexplicably refuse to acknowledge). — Pantagruel
Which supports what I said here:"Dialectical thinking refers to the ability to view issues from multiple perspectives and to arrive at the most economical and reasonable reconciliation of seemingly contradictory information" — Pantagruel
This is akin to what I have said before in that we can have different views of the same thing, but we have to be careful that we aren't confusing our views with what our views are of. In discussing opposing views, we are discussing our views, not what our view is of. To get at what our views are of, we have to find similarities between our views, not differences between our views.
The fact that our views may differ says nothing about what our views are about, but more about ourselves - the viewers. — Harry Hindu
This doesn't fit with what you just quoted. You and I have opposing views, that have yet to be reasonably reconciled. So we haven't yet engaged in any dialectic logic because you don't want to reasonably reconcile our opposing views. You just want to go off-topic and say that I don't understand, or that I'm not grasping it, as if dialectic logic has this nature that I'm not grasping and that my view of it is false, not some degree of truth of it. You keep contradicting yourself with every post.Certainly your counter-argument was applicable, and amplified the issue. In doing so, you thereby participated in the process of dialectical reasoning, and gave a strong argument yourself for the use of many-valued (versus dyadic) logic. — Pantagruel
Seems to support what I said, not what you said. Bravery comes in degrees, not on or off / true or false. Some are braver than others. Tell me, Pantagruel, what room does the word "braver" have in your example? You seem to say that the word would be meaningless if you were to apply dialectic logic to bravery. So it seems that either you have the wrong idea about dialectic logic or the wrong idea about bravery, and how and when to apply dialectic logic (it doesn't seem to work for bravery), and it is reflected by your examplethey do not restrict the number of truth values to only two: they allow for a larger set W of truth degrees. — Pantagruel
You keep contradicting your OP in your attempt to argue for the sake of arguing with me.Well, it would lighten the burden for us but the robot probably won't make it through the day. — TheMadFool
So it seems to me that pain is necessary for survival. What is survival if not the continued existence of the thing as a primary result of the thing's own functioning?Pain is a detector of sorts that alerts living things of potentially life-threatening stimuli. This pain detecting mechanism is wired to responses that aim to relieve/avoid/prevent pain; ultimately saving the organism from grievous injury and death. We could, in a way, say that pain is necessary for survival. — TheMadFool
No, that isnt the case. What is the case is that you see the world in black and white and you often confuse your black for white and vice versa.Or else you simply failed to grasp it because it doesn't fit in your procrustean perspective.. — Pantagruel
What are you doing?It's possible to construct a robot with sensors tailored to prevent injury to the robot. The robot isn't conscious like we are but even without it, it can look after itself reasonably well. Surely, a physical system sans the consciousness can perform orders of magnitude better. — TheMadFool
Pain is a detector of sorts that alerts living things of potentially life-threatening stimuli. This pain detecting mechanism is wired to responses that aim to relieve/avoid/prevent pain; ultimately saving the organism from grievous injury and death. We could, in a way, say that pain is necessary for survival. — TheMadFool
Like I said to Pantagruel. If our opinions are conflicting, then how do you know that our opinions are of the same thing?The question is whether or not there is some universally applicable reliable method for determining which opinion is true when we find ourselves being presented with conflicting opinions about the same things. — creativesoul
If you're asking if you can apply logic to ethical questions, then no. There is no such thing as an objective morality. When it is right to open an economy is when individuals feel safe in going out in public, and that can vary from individual to individual. So it seems to me that you are attempting to answer an unanswerable question, or attempting to answer a subjective question as if it had an objective answer.You stated "logic". I answered that logic alone is inadequate for determining which conflicting opinion is true.
Now you're invoking a philosophical position called "empiricism" and adding it to logic alone, as if to say logic and empiricism are enough - when used in conjunction with one another - to tell which conflicting opinion is true. I'm still objecting to that for it's not true. Logic and empiricism are inadequate. They are not capable of being used as a means to discriminate between true and false claims.
So, in effect you're changing your answer, and/or moving the goalposts. I could object on those grounds, but that would look like a hollow victory, and I'm not interested in winning. I am interested in shedding some much needed light upon an everyday problem.
If speaker A says "We should re-open the economy" and speaker B says "We should not re-open the economy" we have ourselves a real life everyday example to discuss.
So...
Tell me how logic alone can discriminate between which of these two statements is true, if either is and exactly how logic determines that much.
I'll tell you how it cannot, even when - especially when - accompanied by empiricism. — creativesoul
But you aren't merely pointing out that it exists. You attempted to show an example of it's use and failed miserably. In pointed out that it exists, you are pointing out a truth, and even provided (what you thought) is the nature of it's existence.Not at all. I am merely pointing out that it exists, in contrast with your claim that everything reduces to true and false. Cheers. — Pantagruel
I don't see what's so funny, unless it's your silly imaginary universe you're laughing at. Is your imaginary universe funny?:rofl: So, had I said, "if two objects strike each other and then the one, identified as p, having a mass m moves at an acceleration a" then the force acting on p is F = 2 * m * a? — TheMadFool
Huh? :brow:That's because I am capable of dialectical reasoning.
If A mans his post in the face of an attack, then A is brave.
But A can man his post for a while, but abandon it when the fighting becomes too fierce.
So A is both brave and not-brave. — Pantagruel
There are never scenarios where the true/false (binary) state is inadequate. To say that there is, is to deny the law of non contradiction, but to deny the law of non contradiction actually makes use of it, so you end up defeating your own argument.I guess the whole point is that there are scenarios where the true/false (binary) state is inadequate. Even in physics, particles can be in more that one state simultaneously, it's what makes quantum computing possible. So it seems that there are empirical conditions in which the true/false dyad breaks down. Nature, it seems, never learned boolean logic.
So in terms of the OP, can we achieve a mutual understanding such that both your notion, that logic is foundational, and my notion that logic transcends the boolean form, co-exist? — Pantagruel
Well sure, empiricism is just as necessary as rationality, if that is what you mean. If not, then I would encourage you to give examples of where logic/empiricism, alone is inadequate. We can make claims all day, but if you aren't willing to provide examples that can falsify my statements, then it seems that we are at an impasse.The rules of correct inference(logic) cannot tell us whether or not some statement or other is true. If the aim is to determine which of two competing statements is true, then logic is of no help here. It can, however, be used to establish whether or not a statement has been arrived at by virtue of following those rules, if we know the particular kind of logic being used. Logic can help us to determine if statements are reasoned.
Typically, logical statements are held to be better(more reliable) than those that are not arrived at via logical means, however, a statement/opinion can be both valid(a logical statement/conclusion that follows the rules of correct inference) and false.
Logic alone is utterly inadequate for the task at hand. — creativesoul
Sorry, are you saying we shouldn't be discussing how to resolve conflicts of opinion or that we should be? I take the latter view - do you agree?
Note. I am here following my own stricture of trying to establish some common ground. — unenlightened
So if the article had stated "black person" it would be a racist thing? Or if he was described as a black, fat, stuttering, shy, ugly, young man, we are to investigate whether there is a possibility they just didn't like shy people? — Benkei
Sure it does. It basically mandates that the opposite of true is false. It is the root of all philosophical conclusions. If you keep asking, "why?", it basically comes down to, "because it is.", and something cannot be something that it isn't.LNC doesn't give you a logic by itself. It says very little about valid inferences; or plausibility of claims; or evidentiary status; it just tells you not to believe something and its negation at the same time. This is nowhere near enough. — fdrake
I thought we were supposed to be talking about the topic at hand? — Harry Hindu
Yeah, but not on the topic at hand, because you decided to engage in ad hominem political attacks rather than defend your statements on the topic at hand.Oh. I'm glad we agree. — unenlightened
I find it very strange that you don't see your own presuppositions of truth in every sentence that you make - that every statement you make is about how things are - from what dialectical logic is to what your thoughts are.If we are talking about interpretation one, we could basically stick "I think" in front of everything that everybody says, and it will always be true. But why would we ignore the external referents of propositions in this way? — Pantagruel
I thought we were supposed to be talking about the topic at hand?That's right Harry, I forgot, there's no conflict of opinion in politics is there? — unenlightened
I don't see how you could be saying that people are talking to each other if they are "talking" gibberish. This is a contradiction. You need to come back with better arguments.People talk to each other - this is a pattern. However they maybe talking gibberish - this is chaos. I can't explain this any better. You'll have to reread my post and come back with better points. — TheMadFool
Sure, because it's not two or three, etc. It's basically saying:So, "one" in if "one" object of mass m (kg) has an acceleration of a (m/s^2) then the force acting on it F = m * a is central to the quantitative nature of the statement? — TheMadFool
I thought we agreed to use this definition:I'm using your definition of "chaos". Does that include complexity? — TheMadFool
but then you went about using a different definition - the one that refers to complexity, which I showed. Maybe you should be the one that re-reads posts, not me.I agree completely with you that chaos is the absence/lack of patterns. We'll begin from there. — TheMadFool
The topic we are supposed to be talking about isn't a political one. You might want to remove those politically partisan glasses you have on.I would like to suggest to you, in relation to the topic we are supposed to be discussing, that this conflict cannot be resolved, because no genuine communication is taking place. You might as well argue with Trump, because you are a a very bad person, and very illogical, and you are dealing with a very stable genius. — unenlightened
Just read the first sentence in the link you provided. It presupposes some truth.Even if we allow that it is trivially true that my statement is really my statement, you asked merely if there was any logic that doesn't presuppose true and false. I merely pointed out that dialectical logic transcends the true-false simpliciter dyad. I'm prepared to acknowledge that it is always true that I have made any statement I have made. Are you prepared to expand the concept of modal logic beyond the scope of true and false? — Pantagruel
The law of non-contradicton.What laws does the logic you're talking about follow? — fdrake
Logic, like any other process, puts out what you put in. If you put in false premises, you will get false conclusions.Thus the answer, without discussion, "Logic." partakes of this authoritarian attitude. One might suppose that reputable logicians have never been known to disagree. Yet we surely know that this is not the case, and so the word becomes nothing more than a stick to beat one with. — unenlightened
Of course it is. It is about what you think:The statement is not about me, it is about dialectical logic. You are conflating the reference of the statement with its origin. Smacks of the genetic fallacy. Dialectical logic can be many-valued. — Pantagruel
It even presupposes that thinking exists and that you think things.I think dialectical logic transcends the simple true-false dyad of traditional logic. — Pantagruel
Does this statement presuppose some truth about what you think, and that you think?I think dialectical logic transcends the simple true-false dyad of traditional logic. — Pantagruel
In a deterministic universe effects are just as necessary of a condition of their causes as causes are a necessary condition of their effects. The difference between them is spatial-temporal.The apparent problem is that “the grass being wet is a necessary condition for it to be raining”, which is supposed to mean the same thing as “if it is raining then the grass is wet”, sounds superficially like the grass has to be wet first. — Pfhorrest
Sure. I could put a tarp over my lawn and then it would be raining but the grass wouldn't be wet. Sounds causal to me. If I can insert some element into the process to prevent what we claimed was a necessary condition for something else, or show that the effect (wet grass) isn't necessarily the result of it raining (it could be condensation, or someone is watering their grass), then obviously rain isn't a necessary condition of wet grass. It would simply be a matter of misusing/misinterpreting words.That’s why I said “IF it can’t be true...”. For the reasons you mention, it could be true that it is raining and the grass is not wet, so the grass being wet is not in fact a necessary condition of it being raining. But IF it were... — Pfhorrest
Show me the quote you are referring to from which this line of thinking would follow. I just don't see it, so you must be assuming more than what I have said, just as SLX assumes more than what the data they provided is showing.So if the article had stated "black person" it would be a racist thing? Or if he was described as a black, fat, stuttering, shy, ugly, young man, we are to investigate whether there is a possibility they just didn't like shy people?
Funny guy! — Benkei
I mean, you entire post presupposes some truth.logic is presupposed by every sentence and every thought. — Harry Hindu
What qualifies as poor advice is subjective, and one person should not be determining what is poor or good advice for any other individual.you’re propagating poor advice — I like sushi
This is a strange response considering it's the TLDR version of 's post and you said,Logic presupposes truth. — creativesoul
Ah drake...
That deserves permanent preservation!
Brilliant. Beautiful. Clear. Concise. Germane. Practical.
The agreement resonated within while reading. Literally... a visceral affect/effect.
Thank you. My respect for you has just increased exponentially. — creativesoul
Ok.I agree completely with you that chaos is the absence/lack of patterns. We'll begin from there. — TheMadFool
Yes, but is the fact that a pattern exists at all in Universe A indicative that Universe A is not chaotic?1. There is a pattern, a nonmathematical one, in the way the earth interacts with objects that are let go in the air - they always fall. This pattern is called free fall. Call this pattern X.
2. There is another pattern, a mathematical one, in free fall as discovered by Galileo: the distance an object falls is directly proportional to the square of the time spent in falling. Call this pattern Y.
You can see, quite clearly, pattern Y is a pattern in pattern X and pattern X is NOT pattern Y. Keep this in mind. — TheMadFool
Another thing I wanted to mention. Here's another law you're familiar with: if "one" object of mass m (kg) has an acceleration of a (m/s^2) then, the force acting on it is F = m * a. Does the "one" in the sentence that states the law make the law quantitative? By your logic "yes" but as a matter of fact the correct answer is "no". Similarly the "one" in the universe A's law, "if one object is struck by another object, the struck object will move" doesn't make the law quantitative. — TheMadFool
So now you are using the kind of chaos that you said you aren't using - complexity.Now, since pattern X is not pattern Y, it is completely possible for pattern X to be present (no chaos = free fall ) and pattern Y to be absent (chaos = there is no mathematical relationship between the distance an object falls and the time it takes to fall) without contradiction for one is a pattern and the other is the pattern in that pattern - two entirely different things . This is exactly what's the case with universe A which has the nonmathematical pattern, "if struck, move", which you were so kind to point out to me (thanks), but lacks the mathematical pattern "if one object moving at velocity w, at an angle x, strikes another object, the struck object will move at a velocity y at an angle z." Let's call the pattern "if struck, move", pattern/law S. In universe A, pattern/law S exists but what's missing is a mathematical pattern in the pattern/law S. I'm using the term "chaos" consistently and without contradiction. — TheMadFool

Logic.Let us start by supposing that there are two opposing opinions on some matter. Is there a tried and true universally applicable method of determining for ourselves what's best to believe regarding the subject matter? — creativesoul
I don't see how the statement implies that the wet grass occurred before the rain, so I'm failing to see the problem you are posing.If it is raining, then the grass outside is wet.
In what tolerable sense can it be said that the grass outside must be wet (Y) before it can rain? Yes, if it is raining, it is necessarily true that the grass outside is wet. But is it necessary that the grass be wet before it can rain or is raining? — MichaelJYoo
I guess it depends on where we drawn the boundary between raining and not raining. Is it raining when the water drops are condensing and falling from the sky before the water drops hit the ground, and how much water on the grass qualifies it as being wet? This isn't an instantaneous process.Time is not a factor in logical necessity. If it can't both be the case that "it is raining" and the "ground is not wet", then the ground being wet is a necessary condition for it to be raining. That doesn't mean the ground has to be wet first; just that it can't be raining without the ground also being wet. — Pfhorrest
The article says that it is young black men. Race is only a third of the description. The other two being age and sex. So how does it follow that it can only be racism is the cause of all these deaths? If it were racism, then age and sex wouldn't seem to matter, would it?Police are literally a public health risk for black people - black men in particular - in the US. It's an incredible 'stupidity' that just so-happens to kill black people at a rate of 2.5x that of white people. Just one of those inexplicable, magic things that happens because of 'stupidity'. — StreetlightX
Compare the following three:
1. Universe with no laws. There would be absolutely no pattern. This is the chaos you're talking about. I agree with you here.
2. Universe with a nonmathematical law. As you rightly pointed out, there is a pattern that the law describes but does this pattern preclude chaos? — TheMadFool
Universe A:
1. Two objects
2. Law of motion: if one object is struck by another object the struck object will move. This law is non-mathematical — TheMadFool
Seems quantitative to me.Definition:
one:
1. denoting a particular item of a pair or number of items
2. the lowest cardinal number; half of two; 1 — TheMadFool
In Universe A, why does an object move when struck?Why did you say "an incomplete law" and use the word "how"? For the simple reason that the nomathematical law "if an object strikes another object, the object struck should move" is not sufficient to predict the behavior of objects in a universe that has such a nonmathematical law. Why can't you predict? That would be because there is no pattern in the motion of objects in such a universe. Where there is no pattern, there is chaos no? Basically, there is a pattern in that struck objects will move but there is no pattern in how the struck object will behave/move.
In the scenarios I put for consideration the pattern you see is nonmathematical but the chaos is mathematical. I'm not contradicting myself. Why is the pattern nonmathematical? Why, numbers don't figure in it. Why is the chaos mathematical? There's no pattern in the trajectory or speed, both mathematical entities, of objects. — TheMadFool
, and not randomness.Mathematical chaos theory is, to my reckoning, simply about unexpected complexity in fully deterministic systems. — TheMadFool
TheMadFool's assertion was that Universe A is chaotic because the Law isn't a mathematical explanation, while Universe B is orderly because the Law is a mathematical explanation.As must already be obvious, universe A is chaotic as the struck object can assume any velocity and any path - the motion is completely random as the law fails to fully describe motion.
The situation is different in universe B as there is order - the struck object's velocity and path is fully determined by the object striking it. Motion is fully described in this universe and there can be no chaos in the sense that the struck object can assume any velocity or any trajectory. — TheMadFool
Mathematical chaos theory is, to my reckoning, simply about unexpected complexity in fully deterministic systems. Nevertheless, there are patterns that can be discerned. The chaos I'm reffering to is completely devoid of any pattern and is also wholly random and undeterministic except perhaps in a qualitative sense. — TheMadFool
