From Daredevil #55, written by David Mack.

Wolverine tells a story.

"...the story goes like this.

This guy...he was a good guy, but I think he had some problems in the past. Maybe he got in trouble with the law a bit here and there. Maybe he had a rough childhood. Or maybe he fell in with the wrong crowd...or maybe just in general felt like he wasn't living up to his potential for whatever reason.

And in describing his inner struggles, he says, 'There are two dogs inside me. One of the dogs is mean and evil. The other dog is good. The mean dog fights the good dog all the time.'

And when I heard that, I really understood this guy.

I knew that the one dog was like your dreams and good intentions. He is full of purpose. And order. He maybe represents your respect for others and your respect for yourself. Respect for what you can be if you put your heart into it.

And the other dog...he has no respect for anything.

He's like a rabid beast. Crazy and self-indulgent. He blames everyone else for his sickness. He lashes out at every opportunity. He loves nothing but wallowing in the hot darkness of his anger.

So someone asks this guy a question. Someone asks him which dog usually wins.

And the guy sort of looks down and thinks about it for a while. And then after a moment's reflection, he answers. He says this.

He says, 'The dog that wins is the one that I feed the most.'"
