In your own words, write two arguments , one that is valid and one that is not valid. Make sure not to specify which is argument is valid.
EXAMPLE:
Hi Class,
I wanted to share how we write arguments using symbols, and how it can be made clear when an argument is valid or not.
Here’s an example:
Cats don’t like swimming. Tom does not like swimming. Therefore, Tom is a cat.
To write the argument using logic symbols:
Let c = being a cat
s = like to swim
T = being Tom
So, the argument “Cats don’t like swimming. Tom does not like swimming. Therefore, Tom is a cat” would be written:
?⟶∼? (If you’re a cat, then you don’t like swimming.
?⟶∼? (If you’re Tom, then you don’t like swimming.)
____________
∴T⟶? (Therefore, if you’re Tom, then you are a cat.)
So, we know only 1 thing about Tom, that Tom doesn’t like swimming.
And, we know only 1 thing about cats, that cats don’t like swimming.
We have not proven that Tom is a cat! It is possible that some people (and dogs and pigs, etc.) don’t like swimming…
