Hacker has a point, "What it is like" is inherently dualist.  I am my experience.  This experience may have similarities to other things but it is itself.

However, Hacker then says: the question "..amounts to no more than “What is human life like?” – and that has a pretty easy, if rather vague, answer."  Pretty easy? Easy?  Come on Hacker, do the physics and maths, how on earth do events get spatio-temporally arranged like they do in my experience?

Could it be that Hacker's lack of scientific knowledge means that he cannot even see that there is a physical and mathematical problem involved in describing what human life is like?
