But that doesn't seem enough to make something a pain. It's true that pains are caused by injury, and they do make you hop and yell. But they also feel a certain way, and that seems to be something different from all their relations to causes and effects, as well as all the physical properties they may have—if they are in fact events in your brain. I myself believe that this inner aspect of pain and other conscious experiences cannot be adequately analyzed in terms of any system of causal relations to physical stimuli and behavior, however complicated.

In this case, can I replace "relations to" with "relations between"? Will the meaning change?
And .... what's complicated? Is it "system of causal relations"?
Thank you so much!
