One needs to protect himself from his own false beliefs alone; therefore the only wrong thinker, or mental malpractitioner, there is or can be is one’s self. The beam in one’s own eye is the whole of evil. Of what does our human concept consist, and who created it? All our warfare is located within the confines of our thought. Evil cannot be located, because it cannot be confined. Mary Baker Eddy (Oakes, Richard, Essays and Bible Lessons, (Red Book), p.83)
