Which logical fallacy involves assuming a conclusion based on the premise without further proof?

The logical fallacy where a conclusion is assumed based on the premise without additional proof is known as Begging the Question. This fallacy occurs when an argument's conclusion is included in its premises, leading to circular reasoning. Essentially, it asserts that something must be true because it has been stated to be true, without providing any supporting evidence to validate that claim. This can lead to flawed reasoning as it replaces the need for independent evidence with an assertion that relies on the very conclusion it aims to prove.

For instance, if one were to argue that "Ghosts must exist because they are real," they are not providing any additional proof; they are instead restating the conclusion in a different way, thus failing to establish a solid argument. Understanding this fallacy helps in identifying arguments that lack proper support and encourages more rigorous critical thinking.
