I would like to get a better understanding of the term "permissive will". I have read a couple threads on this forum related to this topic, but neither has given me a satisfactory understanding. I desire to know whether there are any Christian philosophers (e.g. Augustine or Aquinas) who discuss this subject, or, on a similar note, which theologians first introduced the term into discussion. At the moment, I contrast this term with two others, God's sovereign will and his declared will, per a conversation with a pastor.
