Integrity is one of the most important and oft-cited of virtue terms. It is also perhaps the most puzzling. For example, while it is sometimes used virtually synonymously with ‘moral,’ we also at times distinguish acting morally from acting with integrity. Persons of integrity may in fact act immorally—though they would usually not know they are acting immorally. Thus one may acknowledge a person to have integrity even though that person may hold importantly mistaken moral views.

When used as a virtue term, ‘integrity’ refers to a quality of a person's character; however, there are other uses of the term. One may speak of the integrity of a wilderness region or an ecosystem, a computerized database, a defense system, a work of art, and so on. When it is applied to objects, integrity refers to the wholeness, intactness or purity of a thing—meanings that are sometimes carried over when it is applied to people. A wilderness region has integrity when it has not been corrupted by development or by the side-effects of development, when it remains intact as wilderness. A database maintains its integrity as long as it remains uncorrupted by error; a defense system as long as it is not breached. A musical work might be said to have integrity when its musical structure has a certain completeness that is not intruded upon by uncoordinated, unrelated musical ideas; that is, when it possesses a kind of musical wholeness, intactness and purity.
