There's certainly nothing original about the observation that conscious experience poses a hard problem.

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 most people accept the existence of qualia.

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

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.

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