Sense data are much more controversial than qualia, because they are associated with a controversial theory of perception - that one perceives the world by perceiving one's sense-data, or something like that.

Actually, I think my view is compatible with much of the work going on now in neuroscience and psychology, where people are studying the relationship of consciousness to neural and cognitive processes without really trying to reduce it to those processes.

Now I have to say I'm a complete atheist, I have no religious views myself and no spiritual views, except very watered down humanistic spiritual views, and consciousness is just a fact of life, it's a natural fact of life.

Studying consciousness tells us more about how the world is fundamentally strange. I think we have a few revolutions to go yet before we get to the bottom of it.

People have managed to avert their eyes and hope for the best.

Although I'm Australian, I find myself much more in sympathy with the Austrian version!

What does it mean, exactly, for a given system to be a neural correlate of consciousness?

I think that consciousness has always been the most important topic in the philosophy of mind, and one of the most important topics in cognitive science as a whole, but it had been surprisingly neglected in recent years.

Actually, I think most people accept the existence of qualia.

Anyway, there is a lot of really interesting work going on in the neuroscience and psychology of consciousness, and I would love to see philosophers become more closely involved with this.

Because the idea of zombies seems to make sense, and seems to, in a certain sense, be possible, I think one can use that to argue against the thesis that everything is purely physical. Now many people, I think, agree that the idea of zombies are conceivable, including people who want to be physicalists.

Why should physical processing give rise to a rich inner life at all? It seems objectively unreasonable that it should, and yet it does.

It probably helps that my background is in the sciences and I can speak the scientists' language.

How does the water of the brain turn into the wine of consciousness?
