Why care about Truth?

Bear with me and I shall tell you, my friend:

1. Everyone has beliefs.

Whether you are conscious of it or not, you have a belief system. This belief system includes a whole slew of things: you have beliefs about who and what you are, where you left your car, what happened in 1492, how likely it is that your face will explode, etc. You may not profess to believe anything—you may even profess to believe nothing—but you are nevertheless ready to act as if certain things are true. For example, you don't behave like a glass of orange juice, and you don’t talk to sinks; when you cut yourself, you don't expect Koolaid to gush out; and you don’t operate on the assumption that our country was founded by gophers who wrote the Constitution by accident during a game of Scrabble.

You even have beliefs about beliefs. And you have beliefs about knowledge, about truth, and about the relation of your beliefs to knowledge and truth. You have ethical beliefs, and you have religious beliefs—again, even if you don’t profess to. Skeptics may profess all day long to believe nothing, yet all day long they accept things as true (that is, they are ready to act as if certain things are, or are not, the case). They may, for example, claim to have no belief whatsoever about whether or not the sun will rise tomorrow, but they still go on as if it will. Agnostics may disclaim beliefs as to whether God exists, yet they are often still ready to behave as if He did not.

You have beliefs. Loads of them. If you didn’t, you’d be absolutely paralyzed, immobilized—unable to act. Having beliefs is, in fact, a necessary condition for action.

2. Beliefs are incredibly important.

Given what I've said above, what we hold to be true is going to hugely impact our actions by definition. I mean, if you want to know what someone really believes, just watch what they do!

(Spoiler ahead: I’m reminded of the climactic scene of Indiana Jones and the Last Crusade, in which Indiana is challenged by Walter Donovan to retrieve the Holy Grail: “It’s time to see what you really believe,” that is, what Indiana is actually prepared to act on. If he hadn't had at least some degree of faith in the power of the grail, he would not have risked his own life for his father's.)

Beliefs are powerful! Crusades, wars, millenia of persecution, planes flying into buildings . . . I mean, holy crap! (no pun intended)

If you agree with me that these are important matters, I really shouldn’t have to say much more. People are ready to act on their beliefs, however wrong they may be, and those beliefs are sometimes, nay, often really messed up.

But this is not only true with regard to large-scale religious beliefs, it's also true on an individual level. If I believe the light is green and it's not . . . uh-oh. (And no amount of rationalization—"But it looked green!"—is going to get me out of the hospital quicker.) It works backwards too: if my neighbor is plotting to kill me, I better believe it (and have some pretty good evidence for it)!

So, what's the point of all this?

3. We need to take care of our beliefs!

We all have beliefs, and it’s clear that beliefs are unbelievably important, because they serve as the basis for almost everything we do: from driving to neighborly relations to suicide bombings.

What does that mean for us? Well, it means that we have a majorly serious and inescapable responsibility to ensure that our beliefs are true!*

Because worse than planes flying into buildings is our secular equivalent: apathy.

Since we are morally obligated to take great aims to ensure that what we hold to be true is actually true, apathy about what we believe is absolutely devastating. And it’s insidious in our culture.

Of course, this shouldn’t come as much of a surprise, because modern thought has many of us under the mistaken conceptions that there is no truth, that knowledge is impossible, and that goodness is subjective!

And if we don’t know, we can’t know, and everyone just has their own morality, who cares? What’s all the fighting about? Can’t we all just get along?!

Well, the good news is that yes, we can! But not if we each have different beliefs about what it means to get along; not if we think that nobody knows the answer—and certainly not if we think that nobody can know the answer; but more importantly to this discussion, not if we operate under explicit I-have-no-beliefs-ism (walking around pretending like we don’t know or believe anything) and think this is going to prevent us from getting into trouble.

We must acknowledge the existence and importance of our beliefs. But most importantly, we have to acknowledge the absolute moral imperative to take responsibility for them, however innocuous they may seem.

So let us start by examining ourselves, and let's clean house! If there's a long-standing falsehood that's been stubbornly preventing us from seeing clearly, let us scrub it off and start over. Perhaps we've been under the delusion that "one more ___ won't hurt anyone." Perhaps we've convinced ourselves that it's his job to reconcile with me. Maybe I still think that I'm at the center of the world, and who are you to tell me that what I'm doing is hurting myself and my family.

Once we've removed the log from our own eye, then we can start, with a healthy dose of truth, love, and humor, to remove the splinter from our brother's.
