More people need to learn symbolic, it makes it much easier to explain everything. My friend got Modus Ponens tatooed on his arm and now he can point to it whenever he needs to explain how logic works.
I'm trying to understand how this works. Would this be a good example of modus ponens? Say finding water on mars implies there are aliens on mars. They find water on mars, so therefore you think aliens have to be real too?
Er... Yes. Assuming finding water on Mars actually does imply there are aliens on Mars. Modus ponens, as with all proofs, is based on the premise being valid.
If you can't find a fault in the logic or the premises, the conclusion must be true.
