Thr33 tests...for a good argument.


Argument:

Cyrille normally does not wear eyeliner. But today, Cyrille has eyeliner on. So Cyrille tattooed the eyeliner.

Good Argument:
1. Premises = plausible.
        2. Premises = more plausible than the conclusion.
3. Argument is valid or strong.

First of all, the two premises of Cyrille normally not wearing eyeliner and having on eyeliner that day is possible.

Second, it is more plausible for the premises of normally not wearing eyeliner and having eyeliner on that day to be true compared to the conclusion of the tattooed eyeliner. Maybe Cyrille all of a sudden decided to temporarily put on some eyeliner that day; it’s possible, instead of permanently applying it through cosmetic surgery. Or maybe she got a bruise that formed a line on her eyelid, or maybe she accidentally marked herself with a black marker, or…

Third, it’s not a valid argument where every way the premises could be true the conclusion is true, but a strong one because the premises can possibly be true and it’s conclusion of tattooing the eyeliner false (at the same time).

Also, since we now that Cyrille does not wear eyeliner makes this a good argument.

  1. this is a good example. It would not make sense for a girl who does not where eyeliner that often to tattoo eyeliner on her. I like this example because it is simple with no ambiguity.

    In addition, I definitely did not know that you could tattoo eyeliner on yourself. I'm guessing for girls who always like to wear eyeliner it's more cost/time efficient. lol. I would be so scared if someone had a ink needle to my eye.
