“ Honesty is a moral virtue, a matter of the will. Honesty means willing the truth with the whole of your heart. This demands sacrifice. We have little hope of attaining honesty unless we realize how demanding it is. It demands sacrifice of self-will, self-image, the desire to win, and the comfort of being right.The “honesty” often praised today is usually only emotional honesty with others, not intellectual honesty with one’s self; only “letting it all hang out,” not asking what is the real truth. Sometimes “honesty” is only a code word for shamelessness. Rarely does it mean the absolute, fanatical, selfless love of truth. ”
