In and , a counterargument is an objection to an objection. A counterargument can be used to Rebuttal an objection to a premise, a main contention or a lemma. Synonyms of counterargument may include rebuttal, reply, counterstatement, counterreason, comeback and response. An attempt to rebut an argument may involve generating a counterargument, or finding a counterexample.
A counterargument might seek to cast doubt on facts of one or more of the first argument's premises, to show that the first argument's contention does not follow from its premises in a valid manner, or the counterargument might pay little attention to the premises and common structure of the first argument and simply attempt to demonstrate that the truth of a conclusion is incompatible with that of the first argument.
A counterargument can be issued against an argument retroactively from the point of reference of that argument. This form of counterargument — invented by the presocratic philosopher Parmenides – is commonly referred to as a retroactive refutation.
