## Is math the same in every universe?

## Can laws of logic be different?

Yes, there have been attempts to construct different rules for logic. You list some of them in your question, i.e. modal, fuzzy, etc. A more radical revision is paraconsistent logic, which does not accept the law of noncontradiction.

## Is logic the science of truth?

In this sense, logic is often defined as the study of valid inference. This contrasts with another prominent characterization of logic as the science of logical truths. A proposition is logically true if its truth depends only on the logical vocabulary used in it.

## Does science rely on logic?

Logic has you thinking with reason and arguments (statements). Scientists use logic because it shows the relationships between the parts of an idea and the whole idea.

## Is logic ever wrong?

In logic, an argument can be invalid even if its conclusion is true, and an argument can be valid even if its conclusion is false.

## Are there limits to logic?

Logical validity is relative to logical systems. Some arguments are logically valid in one logic but logically invalid in another logic. There are various logical systems, each of which has been developed based on some notion of what logic is or should be.

## Can you reason without logic?

It makes no sense to try and justify reasoning without using reasoning because as Hitchens says “Logic is the attempt by humans to make sense”. Without logic, we can’t speak sense and so can’t even formulate the question “how do you justify logic”, because the word justify would be undefined.

## What is the law of logic?

Law of logic may refer to: Basic laws of Propositional Logic or First Order Predicate Logic. Laws of thought, which present first principles (arguably) before reasoning begins. Rules of inference, which dictate the valid use of inferential reasoning.
