From the NY Times blog article: Why Our Children Don’t Think There Are Moral Facts
As a philosopher, I already knew that many college-aged students don’t believe in moral facts. While there are no national surveys quantifying this phenomenon, philosophy professors with whom I have spoken suggest that the overwhelming majority of college freshmen in their classrooms view moral claims as mere opinions that are not true or are true only relative to a culture.
A few weeks ago, I learned that students are exposed to this sort of thinking well before crossing the threshold of higher education. When I went to visit my son’s second grade open house, I found a troubling pair of signs hanging over the bulletin board. They read:
Fact: Something that is true about a subject and can be tested or proven.
Opinion: What someone thinks, feels, or believes.
So what’s wrong with this distinction and how does it undermine the view that there are objective moral facts?
First, the definition of a fact waffles between truth and proof — two obviously different features. Things can be true even if no one can prove them. For example, it could be true that there is life elsewhere in the universe even though no one can prove it. Conversely, many of the things we once “proved” turned out to be false. For example, many people once thought that the earth was flat. It’s a mistake to confuse truth (a feature of the world) with proof (a feature of our mental lives). Furthermore, if proof is required for facts, then facts become person-relative. Something might be a fact for me if I can prove it but not a fact for you if you can’t. In that case, E=MC2 is a fact for a physicist but not for me.
But second, and worse, students are taught that claims are either facts or opinions. They are given quizzes in which they must sort claims into one camp or the other but not both. But if a fact is something that is true and an opinion is something that is believed, then many claims will obviously be both.
