Question

How can I prove that Willy Loman is sane?

Answer 1

I'm not sure how to 'prove' it with any certainty, but you could make the argument that he is not necessarily all that different from the masses. If he's insane, aren't most of us?

Answer 2

He's able to function withing the given perameter's of society. Basically he can hold down a job and set priorities. (pay his bills)

Answer 3

But he isn't making any money from his job, he has to borrow money from Charley just to pay his bills. He also gets fired and is too prideful to take a job from Charley.
