## What is the difference between classical logic and modern logic?

In all three cases—in the assumptions, structure, and the purpose—the traditional system reflects traditional views, and the modern system reflects modern views about reality. Each system is based on a different metaphysic.

## What is the difference between classical logic and symbolic logic?

Symbolic logic has a short history and the traditional or classical Aristotelian logic has a long one. But the difference between them is that of different stages of development. … Classical logic is related to symbolic logic as embryo to adult organism.

## What is the difference between classical logic and fuzzy logic?

In fuzzy logic, a value can belong to several sets at once, unlike classical logic. For example, using our example of speed on the highway, 90 km/h in classical logic is a slow speed; while 90 km/h in fuzzy logic is not totally fast but it is not totally slow either.

## Is quantum logic a logic?

Broadly speaking, quantum logic is meant to be a kind of formal logic that is to traditional formal logic as quantum mechanics is to classical mechanics: a formal framework which is supposed to be able to express the statements whose semantics is the totality of all what is verifiable by measurement in a quantum system

## 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.”

## Is symbolic logic a development form of classical logic?

Answer: Symbolic logic originated in connection with mathematical theory. Symbolic logic has a short history and the traditional or classical Aristotelian logic has a long one. But the difference between them is that of different stages of development.

## What are the types of logic?
