In the town of Salem, Massachusetts, rumors of witches has started. Reverend Parris's daughter has not awoken, and his niece Abigail will only give the same answer. Not admitting to what he saw, Reverend Parris is contemplating whether to let the people know there is witchcraft in the town, which his daughter and niece were involved.
And now you bid me tear the light out of my eyes? I will not, I cannot! You loved me, John Proctor, and whatever sin it is, you love me yet!
Abigail's motivations into accusing others of witchcraft was to clear her name. If people were going to believe her, she would be seen as a good girl. She also wanted revenge on John Proctor's wife because she was jealous.
Reverend Parris knows his niece is not a good girl, and wants to believe the rumors of witchcraft are false. He knows that if the rumors of witchcraft are true, his name and reputation would both suffer.
... But let you say nothing of witchcraft yet. I will not discuss it. The cause is yet unknown. I have had enough contention since I came; I want no more.
