I was once told that math and philosophy jokes are too obscure, too alien and requiring too much thinking to be funny. To that, I still say bite me.
This is a logic joke, and logic is the language of the sophisticated troll (and anyone who has been forced to endure it at the hands of evil philosophy instructors as a part of what they hoped would be an “easy” philosophy minor).
(Modus Ponens) is the inference that if one statement or proposition implies a second one, and the first statement or proposition is true, then the second one is also true.
An example of Modus Ponens in plain English would be:
If I am right, then you are wrong.
I am right.
Therefore, you are wrong.
See? Now I look witty and learned as fuck, and you can too if you own some apparel that sports this truly inspired design.
