Erikson claims that a adult who believes their life has been fulfilling, important, and valuable has attained a sense of integrity.
Integrity is the discipline of being truthful and demonstrating a steadfast and unwavering devotion to high moral and ethical standards. Integrity is defined in ethics as being honest, true, or accurate in one's activities. Judging using the criteria of integrity entails viewing internal consistency as a virtue and recommends that parties having within themselves obviously opposing ideals should account for the disparity or adjust their views. This is how integrity may stand in opposed to hypocrisy. The adjective integer, which means full or whole in Latin, is where the term integrity first appeared. In this application, integrity refers to the internal sense of "wholeness" derived from traits like honesty and moral rectitude.
