Is the Mind Physical?

If we can see that, the difficult case is surely how the mind can be physical. That's the hardest thing to be physicalist about. And people don't have much trouble with the idea that bodies are just physical. Even some aspects of the mind, it's not so hard to understand. But when it comes to the conscious mind, what's going on when you look at a red sofa as a opposed to green leaves? Or what'sgoing on when somebody sticks a pin into your leg? The conscious feelings should be physical. It really is much harder to comprehend.
