Fallacy
An error in reasoning. An argument is called fallacious if it does not follow the formal structures and rules of logic. It is also fallacious if it is not adequately supported and/or does not necessarily lead to the conclusion that the proponent of the argument wants to establish. An example is begging the question (petitio principi). This is also known as circular reasoning, by which one arrives at a conclusion from statements that are themselves questionable and have to be proved. For instanceMajor premise: Genuine yogīs live in the forest and only eat fruit. Minor premise: This monkey lives in the forest and only eats fruit. Conclusion: This monkey is a genuine yogī.
