What theme or life lesson is the playwright the crucible by Arthur Miller trying to communicate to the reader/viewer?

that they should never take social stability for granted. Miller presents society as a fragile, delicate thing, something that can be destroyed by repression, ignorance, and mass hysteria.

"in every dark hour of our national life a leadership of frankness and vigor has met with that understanding and support of the people themselves which is essential to victory. i am convinced that you will again give that support to leadership in these critical days."

in this part of his address, he established his identity as the leader who reflects the american public's ideals. he ascertained that the people will give their support to him, the leader of candor and strength.

"with this pledge taken, i assume unhesitatingly the leadership of this great army of our people dedicated to a disciplined attack upon our common problems."

franklin d. roosevelt arrogates his position to commandeer with his promise to fulfill the american people's need for adequate leadership.
