After each eruption of gun violence, there is also a corresponding eruption in the debates over gun issues. As with all highly charged issues, people are primarily driven by their emotions rather than by reason. Being a philosopher, I like to delude myself with the thought that it is possible to approach an issue with pure reason. Like many other philosophers, I am irritated when people say things like “I feel that there should be more gun control” or “I feel that gun rights are important. Because of this, when I read student papers I strike through all “inappropriate” uses of “feel” and replace them with “think.” This is, of course, done with a subconscious sense of smug superiority. Or so it was before I started reflecting on emotions in the context of gun issues. In this essay I will endeavor a journey through the treacherous landscape of feeling and thinking in relation to gun issues. I’ll begin with arguments.
As any competent philosopher can tell you, an argument consists of a claim, the conclusion, that is supposed to be supported by the evidence or reasons, the premises, that are given. In the context of logic, as opposed to that of persuasion, there are two standards for assessing an argument. The first is an assessment of the quality of the logic: determining how well the premises support the conclusion. The second is an assessment of the plausibility of the premises: determining the quality of the evidence.
On the face of it, assessing the quality of the logic should be a matter of perfect objectivity. For deductive arguments (arguments whose premises are supposed to guarantee the truth of the conclusion), this is the case. Deductive arguments, as anyone who has had some basic logic knows, can be checked for validity using such things as Venn diagrams, truth tables and proofs. As long as a person knows what she is doing, she can confirm beyond all doubt whether a deductive argument is valid or not. A valid argument is, of course, an argument such that if its premises were true, then its conclusion must be true. While a person might stubbornly refuse to accept a valid argument as valid, this would be as foolish as stubbornly refusing to accept that 2+2= 4 or that triangles have three sides. As an example, consider the following valid argument:
Premise 1: If an assault weapon ban would reduce gun violence, then congress should pass an assault weapon ban.
Premise 2: An assault weapon ban would reduce gun violence.
Conclusion: Congress should pass an assault weapon ban.
This argument is valid; in fact, it is an example of the classic deductive argument known as modus ponens (also known as affirming the antecedent). As such, questioning the logic of the argument would just reveal one’s ignorance of logic. Before anyone gets outraged, it is important to note that an argument being valid does not entail that any of its content is actually true. While this endlessly confuses students, though a valid argument that has all true premises must have a true conclusion, a valid argument need not have true premises or a true conclusion. Because of this, while the validity of the above argument is beyond question, one could take issue with the premises. They could, along with the conclusion, be false—although the argument is unquestionably valid. For those who might be interested, an argument that is valid and has all true premises is a sound argument. An argument that does not meet these conditions is unsound.
Unfortunately, the assessment of premises does not (in general) admit of a perfectly objective test on par with the tests for validity. In general, premises are assessed in terms of how well they match observations, background information and credible claims from credible sources (which leads right to concerns about determining credibility). As should be expected, people tend to accept premises that are in accord with how they feel rather than based on a cold assessment of the facts. This is true for everyone, be that person the head of the NRA or a latte sipping liberal academic who shivers at the thought of even seeing a gun. Because of this, a person who wants to fairly and justly assess the premises of any argument has to be willing to understand her own feelings and work out how they influence her judgment. Since people, as John Locke noted in his classic essay on enthusiasm, tend to evaluate claims based on the strength of their feelings, doing this is exceptionally difficult. People think they are right because they feel strongly about something and are least likely to engage in critical assessment when they feel strongly.
While deductive logic allows for perfectly objective assessment, it is not the logic that is commonly used in debates over political issues or in general. The most commonly used logic is inductive logic.
Inductive arguments are arguments, so an inductive argument will have one or more premises that are supposed to support a conclusion. Unlike deductive arguments, inductive arguments do not offer certainty—they deal in likelihood. A logically good inductive argument is called a strong argument: one whose premises, if true, would probably make the conclusion true. A bad inductive argument is a weak one. Unlike the case of validity, the strength of an inductive argument is judged by applying the standards specific to that sort of inductive argument to the argument in question. Consider, as an example, the following argument:
Premise 1: Tens of thousands of people die each year as a result of automobiles.
Premise 2: Tens of thousands of people die each year as a result of guns.
Premise 3: The tens of thousands of deaths by automobiles are morally acceptable.
Conclusion: The tens of thousands of deaths by gun are also morally acceptable.
This is a simple argument by analogy in which it is argued that since cars and guns are alike, if we accept automobile fatalities then we should also accept gun fatalities. Being an inductive argument, there is no perfect, objective test to determine whether the argument is strong or not. Rather, the argument is assessed in terms of how well it meets the standards of an argument by analogy. The gist of these standards is that the more alike the two things (guns and cars) are alike, the stronger the argument. Likewise, the less alike they are, the weaker the argument.
While the standards are reasonably objective, their application admits of considerable subjectivity. In the case of guns and cars, people will differ greatly in terms of how they see them in regards to similarities and differences. As would be suspected, the lenses people see this matter will be deeply colored by their emotions and psychological backstory. As such, rationally assessing inductive arguments is especially challenging: a person must sort through the influence of emotions and psychology on her evaluation of both the premises and the reasoning. Since arguments about guns are generally inductive, it is no wonder it is a mess—even on the rare occasions when people are sincerely trying to be rational and objective.
The lesson here is that a person needs to think about how she feels before she can think about what she thinks. Since this also applies to me, my next essay will be about exploring my psychological backstory in regards to guns.
