The Fallacy of LN Circular Reasoning

[Gil Jesus]

Circular reasoning is a formal logical fallacy in which the

proposition to be proved is assumed implicitly or explicitly in one of

the premises.

For example:

"Since we KNOW Oswald killed Kennedy, any evidence to the contrary is

irrelevant."

Such an argument is fallacious, because it relies upon its own

proposition — "since we KNOW Oswald killed Kennedy" — in order to

support its central premise. Essentially, the argument assumes that

its central point is already proven, and uses this in support of

itself.

Circular reasoning is fallacious due to a flawed logical structure.
