What kind of education did john proctor have in thd crucible?

In The Crucible, John Proctor does not appear to have received formal education beyond basic reading and writing skills typical of his time and societal position as a farmer during the 17th century in Puritan New England. He lacks the advanced theological knowledge and sophisticated language that characters like Reverend Parris and Judge Danforth possess due to their extensive theological training and higher social status.
