It’s not often that you find something that’s a fallacy both logically and creatively — that is, a fallacy to which both researchers and artists are susceptible. Perhaps you’re tempted to tell me I’m committing a category mistake, that artistic fields like fiction and architecture aren’t the sort of thing to which the word “fallacy” could even meaningfully be applied. An understandable objection! But let me explain myself.
I first encountered the term “fallacy of difference” in David Hackett Fischer’s excellent book, Historians’ Fallacies, in which he defines it as “a tendency to conceptualize a group in terms of its special characteristics to the exclusion of its generic characteristics.” So for instance, India’s caste system is a special characteristic of its society, and therefore scholars have been tempted to explain aspects of Indian civilization in terms of its caste system rather than in terms of its other, more generic features. The Puritans provide another case in point: “Only a small part of Puritan theology was Puritan in a special sense,” Fischer comments. “Much of it was Anglican, and more was Protestant, and most was Christian. And yet Puritanism is often identified and understood in terms of what was specially or uniquely Puritan.”
Here’s a less scholarly example from my own experience. I’ve heard several non-monogamous people complain that when they confide to a friend that they’re having relationship troubles, or that they broke up with their partner, their friends instantly blame their non-monogamy. But while non-monogamy certainly does make a relationship unusual, it’s hardly the only characteristic relevant to understanding how a relationship works, or why it doesn’t. Non-monogamous relationships are subject to the same misunderstandings, personality clashes, insecurities, careless injuries, and other common tensions that tend to plague intimate relationships. But the non-monogamy stands out, so people tend to focus on that one special characteristic, and ignore the many generic characteristics that can cause any kind of relationship to founder.
So the fallacy of difference is a fallacy of science (broadly understood as the process of investigating the world empirically) but how is it also a fallacy of art?
