is logic subjective? who set the standards for what is logical and what is not?

Answer 1

Yes, I believe it is subjective!

Standards - I don't have ever heard of written or established one to classifies what is logical and what is not.

People classifies something as logical when this is accepted by the mass and general norm and rules of society.

Something is illogical when it deviates from the rules and norms accepted by the society.
These rules can be written or not!

Answer 2

is logic subjective?
no, while there are disputes about things, the core of logic is beyond dispute.
-a=a
-if a=b, and b=c, then a=c
-if a then b. a. therefore b
-all a's are b's. x is an a. therefore x is a b.
-all a's are b's. some c's are a's. therefore some c's are b's.
all these seem pretty objective to me.

"who set the standards for what is logical and what is not?"
the standards of a lot of logic have been set by Aristototle, Frege, and Russell. I'm not sure if you're implying that because the standards were set by certain people that one can infer that logic is subjective. that inference does not follow at all.

ironically, it would be impossible to argue the issue either way without appealing to an objective logic. without such a logic, the argument that logic is subjective would be incoherent. I think part of the confusion is that people aren't seperating logic in the strict way it's used in philosophy from the ordinary non-philosophical use of the word.

Answer 3

Ok, hold the phone. From reading the other answers there seems to be some confusion about what "logic" is.

Logic is a system of relationships between concepts. It is strictly governed the exact same way that mathematics is governed. When a person says something like "my logic may be different from your logic" or "logic is subjective", what they really mean is "when I come to conclusions through a process of reasoning, my conclusions may be different from someone else's". This does NOT mean that there is anything subjective about logic, any more than there is anything subjective about math.

To make the analogy between math and logic more clear, look at it this way: if two people had the exact same math problem to solve, and they both solved it correctly according to the rules of math, they would both get the same answer. The same goes for logic. If two people started with the same premises and followed the rules of logic to get a conclusion from those premises, their conclusions would be the same.

The reason that philosophers who adhere to the rules of logic are still able to arrive at different conclusions is that they do not agree on what the premises are. In other words, they're solving different math problems, and that is why they're coming up with different answers. In order to get the same answer, they would have to agree on what premises are true.

Answer 4

Well... in Philosophy logic doesn't really exist anymore.... when people are trying to reach wisdom, when people are trying to be wiser.... we tend to challenge logic (common and accepted believes written or not written)...

I just saw a question asking if somebody else thinks everything and everyone is real or that everything and everyone is just an illusion....

Isn't that challenging logic? at least mine..... How can I or you be a mere illusion if we are thinking.... how can everything be an illusion if somebody real must be having and seeing all this illusions.... That's my logic towards that question... but obviosly the guy asking the question might have another way of seeing things...

Challenging "logic" (common beliefs) is an essential part of philosophy... then... is it subjective?

Maybe not for an average person... but for us asking and answering in this Philosophy section is must must be....

Hope that helps!

Answer 5

Logic is that which can be explained either by science or by common sense, things that have been past down from one generation to another can also be found in DNA making it easier to determined from what side of the world one may have came from. In many cases where a body has been exhumed from the ground and test have been done we fine elements of Minerals that can be found only in certain parts of the world (now being Logical about this) these elements that are found only in certain parts of the world can only bring one conclusion on where that person that was exhumed from the ground was from. But there are many things that in this universe can not be traced as logical or fiction that creates conflict with a person's mind to where it can drive a person insane, some say that we are the only creatures that are in all the universe's that are complex-ed enough to figure out what is and what isn't logical. but I beg the differ, through history there has been sightings UFOs and Magical creatures that can not be explained in today's world yet we believe that they did once existed, But is that logical or myth? For centuries we have try-ed to find Atlantis and its mysteries that it held and the source of its demise but its can not be explained logically. Now who set these standards on what is logical ? Even Plato and Nostradamus have tryed to explain these things, and yet it comes still as a mystery to all mortals who have tryed to explain things. Even trying to find Eden has been many mortals quest or finding the fountain of youth, logical but impractical. Now What is logical about Myths? these that have been passed down from generation to generation have had some facts involved, even in the Native American History there are stories of things that can not be Explained by science but yet it is a form of fact that it happened.

Answer 6

Logic is the science of reasoning which is interpreted by each individual subjectively.
