Critical Realism

Representative or indirect realism is also known as 'critical realism' as well!

My 'Dictionary of Philosophy' defines it like this;

Critical realists claim that knowledge of the world can be gained because there is some sort of reliable correspondence between sensa, [sense data to us] or some sort intuitive data, on the one hand, and external objects on the other.

I think the word correspondence is really important and a very useful in talking writing about this stuff: what kind of correspondence is there between 'sense data' and the world they represent?
