Question: Is not all [mental]argument mind over mind?

Answer by Mary Baker Eddy: The Scriptures refer to God as saying, “Come now, and let us reason together.” There is but one right Mind, and that one should and does govern [us]. Any co-partnership with that Mind is impossible; and the only benefit in speaking often one to another, arises from the success that one individual has with another in leading their thoughts away from the human mind or body, and guiding the with Truth. That individual is the best healer who asserts him or herself the lest, and thus becomes a transparency for the divine Mind, who is the only physician; the divine Mind is the scientific healer.
