Today we learn what “Argumentum Ad Absurdum” in logic means.
Argumentum ad absurdum is a Latin term that means “argument to absurdity.” It is a method of reasoning where a person shows that an opposing argument leads to an absurd, illogical, impossible, or ridiculous conclusion — therefore suggesting that the original argument must be wrong.
In simpler terms, if we follow a particular logic all the way, it results in something absurd. Therefore, that logic is flawed. This concept is closely related to the legal and philosophical method called reductio ad absurdum.
In the Philippines, some notable politicians have used this concept in their arguments. In a previous issue, the late Senator Miriam Defensor-Santiago emphasized that the baseless distribution of additional pork barrel funds is absurd, even if the amount to be received appears relatively small, because, in the spirit of absurdity, such amounts may increase significantly as the years go by.
Recently, the incumbent Senate President Alan Peter Cayetano invoked the same concept in arguing that elected officials should not automatically be surrendered to the ICC without undergoing judicial process. According to him, if the ICC could simply arrest anyone through the mere issuance of a warrant, without the conformity of the Philippine judicial system, then, theoretically, any government official could be arrested at any time, potentially leaving the government without leadership.

Through discussions such as this, we hope to contribute, in our own little way, to the improvement of critical thinking and the level of reasoning among Filipinos.
