Unethical public communication is often associated with political propaganda and advertising—especially arguments that feature attacks on character and unfair or misleading use of evidence. If only advocates would stick to the facts and logical reasoning, so goes the popular view, we would restore ethics to the public arena.

When we say that someone argues in an ethical way, do we mean that they follow the rules of logic and logical reasoning? If all advocates were to adhere to logic, would not their arguments also be ethical?

Not necessarily—the rules of logical reasoning do not guarantee ethical argument. The proposition that logical argument equals ethical argument, while it may be mostly true, is not always true. Of course, you are unlikely to be ethical if you intentionally break the rules of argument. (Note the qualifier, “intentionally,” since intent is basic to ethics.) But you can follow the rules of logic and still mislead or deceive your listeners.

The rules of logic and argumentation emphasize the form in which claims in speech or writing are presented. The following argument (presented here in the form that logicians call a categorical syllogism) is logically valid:

All satellites are made of green cheese;
The moon is a satellite;
Therefore, the moon is made of green cheese.

So, logic does not guarantee sound reasoning. In this case, it is obvious that the first premise (the first line of the argument) is not factual. The point is that the quality of an argument often depends upon the quality of the evidence or facts that support it. One scholar writing on the ethics of argumentation makes this point: “arguers may reason correctly” and yet “nevertheless be biased or ‘unfair’ at different levels (selective choice of premises, biased interpretation of evidence, use of loaded terms, etc.)” (Vasco Correia, in a 2012 article in the journal, Informal Logic.)

Of course, all reasoning and argumentation involve some selectivity. We choose some facts and not others for our arguments. The problem is, however, that our mistakes in this selecting can be unintentional or biased in understandable ways.

Such mistakes are especially likely when strongly-held commitments become involved, leading to errors in the choice of premises, the interpretation of the evidence, and so on.

Jonathon Haidt, a social psychologist and the Thomas Cooley Professor of Ethical Leadership at New York University, often points out that, for most of us, belief comes first, logical reasoning comes second. In other words, we determine what we want to prove first and then work out the “logical arguments” to justify that belief. In two books, Haidt presents an image of what psychological research suggests regarding moral reasoning—the “elephant and the rider.” Our use of logical reason is like the efforts of a rider to influence the much stronger elephant, representing our emotional attachments and motivations. (The books are The Happiness Hypothesis: Finding Modern Truth in Ancient Wisdom, and The Righteous Mind: Why Good People are Divided by Politics and Religion.) Another prominent psychologist, Joshua Greene of Harvard University, makes similar points based on research using neuroimaging and behavioral experiments looking at moral decision-making. His findings are presented in the recent book, Moral Tribes: Emotion, Reason, and the Gap Between Us and Them.

If the use of slanted evidence and reasoning comes naturally to us as typical human beings, what can we do? Are we ethically responsible for presenting arguments in which the logical reasoning follows from our tendencies to overlook errors of fact or interpretation in order to win the day? Perhaps our ethical responsibility is to be aware of these error-inducing tendencies. As Portuguese philosopher Vasco Correia says, perhaps we need to strive to exercise argumentative self-control, or vigilance. This calls for systematically making the effort to consider alternatives to our reasoning and evidence. Ethical argumentation, in other words, lies in our commitment to exercising vigilance, especially when we feel strongly committed to our positions.

    Agreed–so you must agree that being logical isn’t the same as being ethical.

  2. Dave Szanto says:

    The problem with how logic is being presented is because it strips facts from the world. In the example where the conclusion was that the moon is made of green cheese, a false premise was introduced to arrive at an erroneous conclusion. Let me give a few analogies to why this is the wrong approach. Learning music with the intention to play flat notes and call it music defeats the purpose of the program. Becoming a chef and mixing ingredients that clash would be a bad idea also. Engineering a robot that pours water into a glass but over fills it is equally useless. Calling these efforts music, cooking, or engineering would be wrong. Why would the study of logic be any different? Logic should be the study of reason as it helps our lives, through sound conclusions! This is a point of emphasis, but a very important one. Teaching logic as rules for validity, and not for soundness, is like trying to feed a cat vegetables. She wont eat it, and we do not believe the moon is made of green cheese either. There is no field of knowledge worth a wooden nickel that does not adapt to the experience or the environment. If reason leads to soundness, while logic only deals with validity, then they should rename logic 101 to reason 101, and teach it accordingly. No one expects walking into a math class and be presented with the following argument. 1 = 2 therefore 2 + 1 = 2. No one would call that math, right? Every single class is dedicated to the search for truth, i.e. soundness. Why does academia let logic courses stick out like a sore thumb?
