Question

Is this argument strong or weak?  

According to Tom Brady (Links to an external site.), if a football is slightly deflated, it is easier to throw. Therefore it's true that a slightly deflated football is easier to throw. 

Group of answer choices

Answer 1

if D then E

D

therefore E

it's a classic Socratic syllogism, always True

an always True argument is a very strong argument

if a Deflated football is easier to throw,

and a football is deflated, then it's easier to throw

BUT your problem doesn't actually say that

It prefaces what would be a very strong argument by saying According to Tom Brady

While Tom Brady is a good authority on throwing footballs, he's not infallible

so it's no longer an Always True argument, but still a very strong argument.

Appeal to Authority is legitimate, not a logical fallacy, if it's a real Authority and the

statement relates to

the Authority's field of expertise.

compare this to

All Men are Mortal

Joe is a Man

therefore

Joe is Mortal

all M are L

J is M

therefore

J is L

Always True, if the premises are True

the conclusion is implicit in the premises

but B says all M are L

J is M

therefore

J is L

only True if what B said is True
