# Logic: The Language of Truth

## Understand and evaluate arguments using philosophical theory

If you believe Mickey is a big mouse and Dumbo is a small elephant, then you must also believe that Mickey is a mouse and Dumbo is an elephant.

But, do you believe that Mickey is bigger than Dumbo?

On this course, youâ€™ll consider the logic behind this argument and explore the concept that when something is true, other things have to be true too.

Youâ€™ll discover logical reasoning theory and explore the vital role words like and, or, not, and if play in making good or bad arguments.

Youâ€™ll also learn how philosophers use a formal language to assess arguments and look closely at how our everyday language and thinking works.

The course is primarily designed for those studying philosophy, maths, or science at A-level or university.

The course will also be of interest to anyone whoâ€™d like to learn more about these subjects and the systematic study of good and bad reasoning

Learners require a basic understanding of formal logic and a keen interest to learn.

There is no need for any specialist tools beyond a pen and paper!
