Explanation : When an argument's premises assume
the truth of the conclusion, instead of
supporting it , a fallacy of begging the
question occurs.
Circular argument is a logical fallacy in
which the reasoning begins with what
has to be ended with. Ignoratio elenchi is
a logical fallacy of apparently refuting
an opponent while actually disproving
something not asserted. Petitio Principii is
a fallacy in which a conclusion is taken for
granted in the premises.
