## Is math the same in every universe?

Not only could mathematics be different on a different planet or in another universe; which are of course unprovable one way or the other; but **mathematics could and actually has been different at different eras on this planet.**

## 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?

## 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.
