# Is there any exception or rebuttal to the law of noncontradiction?

No, there is no exceptions. All purported “rebuttals” of the law of contradiction are based on the same fallacy, the fallacy of equivocation. Deductive logic is defined as based on the law of contradiction.

## Can the law of Noncontradiction be proven?

In any “complete” logical system, such as standard first-order predicate logic with identity, you can prove any logical truth. So you can prove the law of identity and the law of noncontradiction in such systems, because those laws are logical truths in those systems.

## Does quantum mechanics violate the law of Noncontradiction?

Quantum physics does not violate the Law of Noncontradiction. Second, no correlation is established between Quantum Physics and a Law of Logic. The designation “physics” is categorically antithetical to “Law of Noncontradiction” because Noncontradiction is not a physical identity whereas it is a mental identity.

## Why does the law of non-contradiction work?

In logic, the law of non-contradiction (LNC) (also known as the law of contradiction, principle of non-contradiction (PNC), or the principle of contradiction) states that contradictory propositions cannot both be true in the same sense at the same time, e. g. the two propositions “p is the case” and “p is not the case” …

## What would be an example of the law of Noncontradiction?

The law of non-contradiction is a rule of logic. It states that if something is true, then the opposite of it is false. For example, if an animal is a cat, the same animal cannot be not a cat.

## What is Aristotle’s law of Noncontradiction?

According to Aristotle, the principle of non-contradiction is a principle of scientific inquiry, reasoning and communication that we cannot do without.

A logical contradiction is the conjunction of a statement S and its denial not-S. In logic, it is a fundamental law- the law of non contradiction- that a statement and its denial cannot both be true at the same time.

## Does quantum mechanics violate the laws of logic?

No, it does not violate the laws of logic.

## Can laws of logic be broken?

No. A nonexisting being can not break any laws.

## Does quantum mechanics defy logic?

As Ball puts it: “It’s not so much understanding or even intuition that quantum mechanics defies, but our sense of logic itself.” Yet why should atoms conform to human-scale norms? “We have absolutely no reason to expect that it is ‘reality all the way down,’ ” Ball writes.

## What is true of the law of Noncontradiction quizlet?

The Law of Non-contradiction is that a statement CAN’T be both true and false at the same time and in the same sense. … If any statement is true, then it is true.

## What are rules of logic?

There are three laws upon which all logic is based, and they’re attributed to Aristotle. These laws are the law of identity, law of non-contradiction, and law of the excluded middle.

A contradiction is a situation or ideas in opposition to one another. Declaring publicly that you are an environmentalist but never remembering to take out the recycling is an example of a contradiction. A “contradiction in terms” is a common phrase used to describe a statement that contains opposing ideas.

So some contradictions are true. They are all false, by the way, be- cause of their form; this much carries over from classical logic. Some contradictions are simply false, i.e. they are false without being true.
