Tautology
A statement that can never be false
Tautology is a logical concept that refers to a statement that is true by definition or by its logical form. It is a type of circular reasoning in which the conclusion is already contained in the premises. In other words, a tautology is a redundant expression that uses different words to say the same thing.
Example of Tautology:
1. It is what it is.
The statement is redundant and does not provide any additional information.
2. The reason why he did it is because he wanted to.
The words why and because convey the same meaning and make the statement redundant.
3. A circle is a shape that is round.
The definition of a circle already includes the concept of roundness, making this statement a tautology.
In general, tautologies are not considered useful or necessary in logical arguments or any form of communication because they do not provide any new information or insights. Therefore, it’s important to avoid using tautologies to ensure effective and concise communication.
