Responsibility, in contrast to formal education, is vital to leadership. Barnard asserts that responsibility derives from the existence of a moral code: he defines morals as "personal forces or propensities of a general and stable character which tend to inhibit, control, or modify inconsistent, immediate, specific desires, impulses, or interests, and to intensify self does not imply responsibility. Responsibility comes when a moral code actually governs individual behavior. Thus, it is possible for a person to be moral but not responsible, although a person cannot be responsible without a moral code.
