The fullest expression of Filmer's thoughts is found in "Patriarcha, or the Natural Power of Kings", published posthumously in 1680, but probably begun in the 1620s and almost certainly completed before the Civil War began in 1642. According to Christopher Hill, "The whole argument of... "Patriarcha", and of his works published earlier in the 1640s and 1650s, is based on Old Testament history from "Genesis" onwards". Filmer's modern proponents counter this by noting that the focus on Filmer's biblical arguments neglects his stronger arguments from history and logic.
