While Plutarch may not be a great theologian...certainly not a Christian his quote is quite good. I feel sure that he got it from the then current thinking of the wisest man to ever live, the one and only King Solomon. Solomon expressed it like this: "As a man thinks in his heart, so is he." Proverbs 23:7.
Solomon's dad, King David, put it like this: "Create in me a clean heart, O God; and renew a right spirit within me." Psalm 51:10
Our Lord and Savior, Jesus Christ put it like this: "Blessed are the pure in heart, for they shall see God.. Matthew 5:8.
No matter how you put it...our attitude will totally affect our reality!
