According to Wikipedia honesty is:
“the human quality of communicating and acting truthful and with fairness, as best one is able. It is related to truth as a value. This includes listening, reasoning and any action in the human repertoire, as well as speaking.
Superficially, honesty means simply, stating facts and views as best one truly believes them to be. It includes both honesty to others, and to oneself (see: self-deception) and about ones own motives and inner reality.”
