What type of argument involves assuming the conclusion in one of the premises?

The type of argument that involves assuming the conclusion in one of the premises is referred to as "petitio principii," which is also known as circular reasoning. In this logical fallacy, the argument's premises restate the conclusion rather than providing independent support for it. This results in a circularity where the argument goes in a loop, ultimately failing to establish any new information or evidence to substantiate the claim being made.

For example, if someone argues that "Reading is important because it is essential to one's education," they are essentially restating the conclusion that reading is essential without providing further justification. This type of reasoning is problematic because it does not advance the argument or help persuade others who might not already agree with the conclusion.

Understanding this concept is important for recognizing flawed arguments in various contexts, such as writing, debates, or discussions, where sound reasoning is essential for effective communication and persuasion.
