"You're asking the wrong question, I think. Asking for a 'who' in this context is mistaken. Not everything that happens happens as a result of some conscious, directing agency."
When did science become about the right or wrong question?
Whose law is it that "not everything that happens happens as a result of some conscious, directing agency".
Doesn't this mean that life is a lottery or a bad accident depending on the status of ones life???
On your first question: Science is always about asking the right question. When a problem finally gets posed in a way that makes it amenable to study, progress usually follows. Until it does, little progress is made. (Case in point: When Galileo started asking how long does it take freely falling objects to traverse fixed distances rather than why do falling objects fall, he discovered the constant acceleration of gravity and brought modern physics into existence.)
On your second question: it's not a law, it's an observation.
On your third question: Uh, pretty much so.
I think you missed the point.
