Define Logic, will you? - Help.com

common sense. a sense not so common.

So you are saying that because some people abuse a term, the thing that the term originally referred to therefore has no value? I guess you are a true believer in your anti-logic campaign.

I am referring to your post. Some people misuse the word logic, so you conclude that there is no value in logic itself.

ru guys arguing? wats the logic

Aristotle codified a set of rules, which given the correct premises, will result in the correct conclusion every time.

That is logic.

Basically, you have a set of premises, or observations and reasons, which you make inferences from to derive a conclusion.

Example:

1. Socrates is a man. // Premise
2. All men are mortal. // Another premise
3. Therefore, Socrates is mortal. // Inference and conclusion

The main concern is to avoid incorrect premises, incorrect inferences, and logical fallacies.

Example:

1. Honest men always get jobs. // Incorrect premise. Honest men sometimes do not get jobs.
2. Billy is an honest man. // Premise
3. Therefore, Billy is certain to get a job. // Incorrect conclusion, because of an incorrect premise. Billy MAY get a job, but he is not GUARANTEED to get one only because he is honest.

Probably that set of rules represents what most people would consider the meaning of logic. The advantage of defining it like that is that it is also more or less understandable in a similar way by different people, which is of course a hard thing to accomplice and very useful in communication.
Now as with all words the word logic will also be used often in a less standardised way by people who want to express different things with it.
one could argue that the word therefore also could get such a new meaning if it is used by many people in such a way.
I suppose a good way to deal with people using it in another way would be to ask them if they mean logic as the defined set of rules and logical as consistent with those rules, and if so, whether they can demonstrate the logic according to those rules,
or if they mean something else by it ask them if they can clearly define/explain in understandible terms what they mean by it, and if more suitable words could be used to express that meaning, request them to use those instead to avoid confusion.

It should also be mentioned that logic rules cannot decide human behavior. There is no such thing as a logical action.

Thanks for what?

I believe in rationalizing and explainations. I also think there are different measures to logic. You can have common logic, which shouldn’t permit evaluation unless you’re mentally challenged. And then you have more advanced logic which some people would unquestionably agree on, and some might ask you to exhibit the perspective to a certain degree. In any case, logic is the science of reasoning and should always have a prepared inference whether it’s elementary or compound. It’s so easy to use it as a safeguard. I normally don’t substantiate my logical statements, unless I feel the need to or if someone inquires it.

Logic is a thought process. Something cannot be logical without a method of reasoning that keeps us from knowing the truth. The inability to think critically makes us vulnerable to manipulation by those skilled in the art of rhetoric. Thinking critically requires removing all emotion. Deductive reasoning, sometimes called deductive logic, is reasoning which uses deductive arguments to move from given statements (premises) to conclusions, which must be true if the premises are true.[1] An example of deductive reasoning, given by Aristotle, is

* All men are mortal. (major premise)
* Socrates is a man. (minor premise)
* Socrates is mortal. (conclusion)

Logic is in the eye of the beholder, therefor man’s logic is flawed.

More condensed: I think logic is a methodical arrangement of decorative words which produces eloquence.

hahahah!

*Thinking critically requires removing all emotion. (major premise)
*Healthy human beings are not capable of removing all emotion. (major premise)
*SoulRising is a healthy human being. (minor premise)
*SoulRising does not meet his own requirements for thinking critically. (conclusion)

So, do you either agree with the conclusion, or if not, with which of the premises would you disagree? :-P (O sorry, smilies express emotion, therefore they must not be logical…teehee, shame on me!)

I use LOGIC as a spur. If I am striving to sort out a problem, and no mattter what I do to solve it, it just won’t aspic, I turn totally to logical thinking. I really do believe that in the end, everything that has been solved successfully has been thought out logically. “Sound thinking and proof of reasoning”

No. There are a lot of conclusions that aren’t justifiable with logic, but are justifiable with reason.

I believe that reasoning is what enables us to be able to know the difference between right and wrong…Reasoning tells you NOT to jump off of the Golden Gate Bridge….whereas logical thinking tells us that if we do, we are certainly guppie food….

critical thinking vs. logical thinking vs. rational thinking….
C’mon my wise friend, B….
Help me to sort this out before I blow a head gasket….LOL! :o)

Sitting here, waiting for my car to be done with an oil change…then taking off….
tl=dr
yesss, B….I remember that kind of thinking….
And jj, you must’ve been straight on my heels with ^^^that reply!!
Hehehe I read your reply and my chin hit my chest…:oO
What??
B—Need your input on my reply…..ok?

Yes. They also have a confused idea about reality, theory, and pretty much anything that revolves around empiricism. It might be the primary reason we’re falling behind other countries in the field of education.

Maybe a sense of entitlement has something to do with that.

Maybe the lack of world history education that includes credit/Usery history would help the American Public’s ability to have “logic” after years of a Quality education within our own public schools.

Logic is determined by cause and effect - trying to put 12 ounces of water into a 8 ounce glass will cause an overflow and a mess on the counter.

Reason generally links thoughts to form a conclusion based on applied knowledge or inference. “The sidewalk is covered in ice, ice is slippery, if I walk on the sidewalk I MAY fall.”

Logic can oppose Reason but Reason cannot oppose Logic.

“Thus what I thought I had seen with my eyes, I actually grasped solely with the faculty of judgment, which is in my mind.” Descartes

Well, those are some excellent metaphors that demonstrates logical rendition verses a reasonable rendition. However, I think there is a thin, transparent wall seperating the two terms. Dropping by the grocery store on the way home from work to pick up some milk would be reasonable. But logically cogitating this for a moment, wouldn’t also be sufficient to say that the resolution is logical? I know I’m probably a vexation to some people here, but let’s not forget the definition of the word itself. “Logic,” is exact, valid, and rational reasoning. I stand firm in claiming that reasoning is vitally attributed to logic; and without reasoning, well, the logic is futile.

Correct mills…Logic allows or opposes Reason. But Reason can’t do the same for/to Logic.

Logic will always exist based on fact learned from cause and effect.

Reason only exists because the human mind creates it and uses logic, induction or teduction to form a thought process - but it’s not Logic.

Taking your example - stopping by the store to pick up milk on the way home is reasonable.

Change your example - I will save mileage and gas if I stop at the store on the way home is logical.

It’s somewhat a matter of semantics but there is a difference.

The english language has been abused for so long that we exchange words inappropriately so that the definitions become so diluted the true meanings are lost.

I think the simplest way to distinguish between logic and reason is that logic always has some objective premise for it. Reason does not.

effects the Vulcan grip on Brian….

that’s better…we vulcans like peace especially when you agree with us!

I suggest a tattoo…

3 x 5 cards are wonderful for out to lunchers like us, B…hehehe…Sooooo THAT is why you don’t talk to me anymore,eh???
Ya went and forgot me…:o/ *sighhhhhh*
