Question on arther miller?

Yes he wrote the essay "Why I Wrote the Crucible" which is explained by its title and can be found here: http://warren.dusd.net/~dstone/Resources/11P/M_NY.htm. He outlines many good facts and opinions on the crucible. You may also want to read "Tragedy and the Common Man" here: http://vccslitonline.cc.va.us/tragedy/milleressay.htm. He writes here about what he thinks a tragic hero is. And btw its Arthur not Arther.
