What is the difference between an unsound argument and an invalid argument?

Answer 1

Both are insane.

Answer 2

Hmmmmm

(1) All arguments are either invalid or valid;
(2) All valid arguments are either unsound or sound.

This can be explained as follows:

(a) Invalid argument
(b) Valid argument ----(b1) Unsound argument
(b2) Sound argument



A valid argument is an argument in which, IF you accept the premises, THEN you must accept the conclusion, or else you are contradicting yourself.

A sound argument is a valid argument in which each premise is true. And since the argument is valid, the conclusion must be true, also, because it is impossible, in the case of a valid argument, for the premises to be true and the conclusion be false.
