The Truth Doesn't Change

Many people, including some Christians, think that the truth changes. They may even rashly think or say that everything changes. Both of these ideas are totally false, self-referentially absurd, and anti-Christian. Let's quickly dismiss the foolish idea that everything changes. One could refute it by submitting various counter-factuals, or things that do not change. Or, one could be like David and cut off the head of this stupid Goliath with his own sword. If one asserts the proposition "everything changes," then one may ask if that principle itself changes. If X stands for the principle that everything changes, then one may ask if X itself changes?

There are only three options: 1) Everything changes 2) Some things change and 3) Nothing changes. Anyone in their right mind knows that #2 is the case in reality. If one believes #1 is the case, then they have to believe that the proposition or principle of #1 itself changes. If the principle itself changes, then it would have to be false and change into the position of either #2 or #3.

Related to this idea is the notion that the truth itself changes. Some people may think that the truth changes because everything in nature seems to change. I've heard illustrations concerning weather patterns, colors and other things that seem to be relative. These people fail to properly understand the propositional element to truth (truth is not less than the propositional, but it is more than merely propositional), and what is actually being asserted in any given case. Consider a color illustration for an example.


Here's a picture of a dragon. Suppose I utter the proposition, "the dragon is red." Someone might say that this is relative and illustrates that the truth changes, because the color of the dragon may change under different lighting conditions, or to those color-blind. What they fail to understand is the true nature of the proposition. As I said, I was the one uttering the proposition. The proposition can be clarified by saying, "Tony said the dragon is red." Now, I am not saying that everyone sees the dragon as red when I utter the proposition, so the redness is person sensitive. The proposition is actually, "Tony is being appeared to redly when viewing this dragon." Not only that, one needs to further clarify the proposition because it is time sensitive when uttered. I am typing this at 6:30 am on December 6th, 2005. The true nature of the proposition is this, "Tony is being appeared to redly when viewing this dragon at 6:30am on December 6th, 2005." We might even clarify the location by saying, "Tony is being appeared to redly when viewing this dragon on his computer at 6:30am on December 6th, 2005 in his bedroom in Irving, Texas."

No one in their right mind communicates this way in everday life. We just say "the dragon is red" because we know our listeners automatically understand (at least the sane ones) most of the contextual elements involved. They understand what is being said without all the other tedious details, so we leave them out. But, if we are dealing with people who think the truth changes, then we need to bring out that which is normally understood in order to get to the nature of the truth claim. If we say, "it's raining," we normally mean something like, "it appears to me that it is raining at time (T) in place (P)."

Just because it may not rain at other times, or that I may see the dragon differently in different contexts, it does not follow that the truth has changed. If I turn color-blind tommorrow, it's still true that the dragon appeared redly to me at 6:30am on the given date, and in the given location.

Christians should be the last people to think that the truth changes, or that everything changes. Christianity not only teaches that the truth doesn't change, but that the truth is eternal. Since God exists and is a maximally perfect being possessing all great-making properties (which necessarily includes exhaustive knowledge), it follows that he knows all true propositions. Among the true propositions that God knows eternally is that the dragon would appear redly to Tony in the given place and at the given time. Not only should Christians not think that the truth changes, but they are bound to believe it is eternal! Any other position is self-referentially absurd.
