I always struggle with definitions of ethics and morality. Michael Jensen, of Harvard Business School throws integrity into the mix of terms.
Here are his definitions:
Integrity: A state or condition of being whole, complete, unbroken, unimpaired, sound, in perfect condition.
Ethics: In a given group, ethics is the agreed upon standards of what is desirable and undesirable; of right and wrong conduct; of what is considered by that group as good and bad behaviour of a person, group or entity that is a member of the group, and may include defined bases for discipline, including exclusion.
Morality: In a given society, in a given era of that society, morality is the generally-accepted standards of what is desirable and undesirable; of right and wrong conduct, and what is considered by that society as good or bad behaviour of a person, group or entity.
It seems he moves up the chain from individual, to groups, and to a larger society with the three concepts.
He also points out that morality and ethics have a good and bad side to them.They relate to desirable and undesirable behaviors.
On the other hand, integrity is more of a yes or no proposition. You either keep your word or you don’t. I suppose there is some gray in between.
Since Jensen is a business school professor, not a philosophy professor, he is researching the effect of integrity on business performance.
