Perhaps the most calamitous of the casualties of our postmodern age is the loss of belief in objective truth.
The notion that all truth, except, perhaps, for mathematical truths, is conditioned by race, gender and economic class has become axiomatic in contemporary discourse. What's true for you, we often hear, isn't true for me. The underlying assumption is that truth is socially constructed and subjective, and that each of us possesses our own personal truth.
I ask students in my classes for a show of hands of those who believe that something can be true for them but not for me, and it frequently happens that over half the class raises a hand.
These students, I believe, are a victim of muddled thinking. When I then ask them to give me an example of something that's true for them but not true for me they'll often say something like, "I'm 19 and you're not," or "I was born in Europe, but you were born in the U.S."
What they don't see in the examples they give is that if it's true for them that they are 19 years old then it's true for everyone that they are 19 years old. How could it be true for Joe that he's 19 but not true for Mary that Joe is 19? How could it be true for Mary that she was born in Europe but not true for Joe that Mary was born in Europe?
As I said, this is muddled. If it's true that Mary was born in Europe then it's an objective truth. It's not just true for Mary, it's true for everyone.
What I think the students really mean to say is that there are things that are true about them that are not true about others. This, of course, is quite right, but it's an entirely different proposition.
Here's another illustration of the same confusion. Sometimes we hear people say, in a rather inchoate way, that, "It's true for Joe that God exists, but it's not true for me." But, if it's true for Joe that God exists, then it's true for everyone that God exists. How could it not be? God doesn't just exist for some people and not for others.
What the speaker is actually trying to say is that, "It's true that Joe believes that God exists, but it's not true that I believe that God exists." This might well be so, but it's a different claim altogether. Moreover, if it's true that Joe believes that God exists then it's objectively true for everyone that Joe believes that God exists.
God's existence or non-existence is an objective state of affairs. His existence is not contingent upon whether anyone believes or doesn't believe He exists.
The notion that everyone has his or her own truth is really quite absurd. All of us may have our own opinions, our own beliefs, our own memories or our own eye color, etc. but no one has his own truth. Whatever is true for any of us is objectively true for all of us, even if it's not true about all of us.
The notion that truth is subjective, that it's whatever we feel strongly, and that my truth isn't necessarily your truth is a product of intellectual carelessness foisted upon us by the postmodern embrace of subjectivity. The sooner we all get over it the better off we'll be for it.
