David Deutsch on "And Why?"

David Deutsch's answer to the Edge World Question Center 2001 "What questions have disappeared?". I've noted this down largely for my own future reference. My come in handy for PhD stuff.

"What Questions Have Disappeared...And Why?" Funny you should ask that. "And why? " could itself be the most important question that has disappeared from many fields.
"And why?": in other words, "what is the explanation for what we see happening?" "What is it in reality that brings about the outcome that we predict?" Whenever we fail to take that question seriously enough, we are blinded to gaps in our favoured explanation. And so, when we use that explanation to interpret regularities that we may observe, instead of understanding that the explanation was an assumption in our analysis, we regard it as the inescapable implication of our observations.
