If I oversleep, I will be late for my 0830 class. I wasn’t late. Therefore, I did not oversleep. This is a valid and sound deductive argument because both premises are true and the conclusion follows from the premises.
If I oversleep, I will be late for my 0830 class. I didn’t oversleep. Therefore, I was not late for class. This is an invalid deductive argument although both of the premises are true. Even though I didn’t oversleep, I could still be late for class if I had an accident on the way to class or my car wouldn’t start.
I chose the logical fallacy called post hoc ergo propter hoc. It assumes that temporal sequence implies causation.
Look at all of the bad things that happened to Canada while my opponent was in office. If you don’t want to elect an official who will bring about such bad things, then you should vote me.
These statements represent a fallacy because it assumes that all of the bad things that happened in the country while the opponent was in power were caused by him, which may not be true.
