In "Unity of Good," under the chapter heading "A Colloquy," Mary Baker Eddy records an imaginary conversation between good and evil. Here our Leader writes (p. 21), "If we observe our mental processes, we shall find that we are perpetually arguing with ourselves; yet each mortal is not two personalities, but one." She continues, "In like manner good and evil talk to one another; yet they are not two but one, for evil is naught, and good only is reality."
The Bible records many similar conversations. One of these was in Gideon's experience, as he threshed wheat by the wine press, turning over in his thoughts the predicament in which Israel found herself under Midianite oppression.
We read in Judges (6:12, 13): "And the angel of the Lord appeared unto him, and said unto him, The Lord is with thee, thou mighty man of valour. And Gideon said unto him, Oh my Lord, if the Lord be with us, why then is all this befallen us?"
