 One can also ask how types of integrity are distinguished from each other. Halfon (1989, 55) argues that we distinguish between types of integrity in terms of commitments to specific kinds of ends, principles and ideals. However, not every end creates a distinct type of integrity. Trivial ends, like train-spotting, do not introduce a new species of integrity. To count as being a type of integrity, the sphere of action and commitment in question should be a complex and valuable human pursuit that has distinct ways in which integrity is demonstrated. Robust examples are intellectual integrity and artistic integrity. On this way of looking at the matter, personal integrity and various specific types of integrity tend to be run together. Integrity is seen as the one virtue: essentially the same virtue expected of one’s life partner, a friend, an employee, a priest, a teacher, or a politician. (See Benjamin, 1990; Calhoun, 1995; Halfon, 1989; and Grant, 1997.) Professional integrity then becomes a matter of the extent to which a person displays personal integrity in professional life. Halfon (1989, 53), for example, argues that types of integrity may overlap, ‘So a person who is an artist by profession may come to possess professional and artistic integrity in virtue of performing one and the same action or fulfilling one and the same commitment’.
