Consistency and Ethics

Developed by Manuel Velasquez, Claire Andre, Thomas Shanks, S.J., and Michael J. Meyer

Consistency—the absence of contradictions—has sometimes been called the hallmark of ethics. Ethics is supposed to provide us with a guide for moral living, and to do so it must be rational, and to be rational it must be free of contradictions. If a person said, "Open the window but don't open the window," we would be at loss as to what to do; the command is contradictory and thus irrational. In the same way, if our ethical principles and practices lack consistency, we, as rational people, will find ourselves at a loss as to what we ought to do and divided about how we ought to live.

Ethics requires consistency in the sense that our moral standards, actions, and values should not be contradictory. Examining our lives to uncover inconsistencies and then modifying our moral standards and behaviors so that they are consistent is an important part of moral development.

Where are we likely to uncover inconsistency? First, our moral standards may be inconsistent with each other. We discover these inconsistencies by looking at situations in which our standards would require incompatible behaviors. Suppose, for example, that I believe that it is wrong to disobey my employer, and also believe that it is wrong to harm innocent people. Then suppose that one day my employer insists that I work on a project that might cause harm to innocent people. The situation reveals an inconsistency between my moral standards. I can either obey my employer or I can avoid harming innocent people, but I cannot do both. To be consistent, I must modify one or both of these standards by examining the reasons I have for accepting them and weighing these reasons to see which standard is more important and worth retaining and which is less important and in need of modification.

A more important kind of inconsistency is that which can emerge when we apply our moral standards to...
