"Let me consider this as a resolution by which I pledge myself to act in all variety of circumstances and to which I must recur often in times of carelessness and temptation - to measure my conduct by the rule of conscience."
-Ralph Waldo Emerson (1803-1882)
Just as conscience is a compass, it is also a measurement devise, according to Emerson. We really know how well we are doing, we don't need anyone's judgement or opinion of our behavior - we have our own conscience to mark our progress. There is nothing as freeing as a clear conscience.
